Notifies me whenever there's a problem so we don't have to constantly watch the screen
Pros and Cons
  • "The comprehensiveness of the security features that Kerio Control provides us with is good. Before GFI had it, they would have more updates. The updates have been slower, but I like the things that they keep adding like the ability to block by country. I use pretty much every feature."
  • "I can no longer renew my subscription directly with GFI but we have to go through third-party resellers like CDW. The first time I did it with CDW. I went to CDW and it was almost like they didn't even know anything. They didn't know what package I was supposed to get. Then after I got it, it took almost five days to get everything working."

What is our primary use case?

I use Kerio Control is several different places. I use it at home. I also have a firewall at my grocery store. I have a server on the internet that uses Kerio Connect, and I have Kerio Control in front of it.

How has it helped my organization?

It has improved my organization because I am able to back the mail server through the tunnel to my house. All the video cameras at the store get copied and backed up to my house as well. For example, if I had a break-in and someone took the video server, I would still have copies of all the videos.

Kerio has saved time for those who manage security. It notifies me whenever there's a problem or when something goes wrong so we don't have to constantly watch the screen. It saves us 20 to 30 man-hours a week. 

What is most valuable?

The custom firewalling is pretty intuitive. You don't have to sit there and learn a new language or anything like that. You can just block this, open that, allow this, just allow that. With a lot of firewalls nowadays, you have to know a language. You have to sit there at the keyboard and type in special commands, and those commands are not used anywhere, just for that particular brand of firewall. Connecting the two up in two different locations for a tunnel is easy.

The comprehensiveness of the security features that Kerio Control provides us with is good. Before GFI had it, they would have more updates. The updates have been slower, but I like the things that they keep adding like the ability to block by country. I use pretty much every feature.

Kerio Control gives us everything in one solution.

The firewall and intrusion detection features are pretty good. I haven't had an issue that I know of. I hope no one's gotten any. I think it's good.

I also like the malware and antivirus features. It's sitting in front of my email server and the email server has antivirus too. The firewall catches it before the email server even catches it, so they work pretty well.

I like the VPN but I don't use content filtering that much. It works pretty well but a lot of times kids can get around that kind of stuff. I don't have kids that age anymore, so I don't have to worry about it. I don't use the content filtering that much.

Kerio is easy to use. If you don't know tech, you can't just get up and do it. Nothing can be that easy, but you don't have to be a rocket scientist to do it. `

What needs improvement?

The only thing that I have a problem with is not so much the product itself, but back when Kerio had it, I could call up Kerio or send an email and do an upgrade online. I could renew my subscription online. But now, I have to go through a third-party, and it seems clumsy. 

I can no longer renew my subscription directly with GFI but we have to go through third-party resellers like CDW. The first time I did it with CDW. I went to CDW and it was almost like they didn't even know anything. They didn't know what package I was supposed to get. Then after I got it, it took almost five days to get everything working. I used to be able to go to Kerio's website and then add the stuff to my cart, use my credit card, and it would bill me. Everything would be working in a few minutes. But now, if your subscription is getting ready to expire, you better give it a week or two.

Learn what your peers think about KerioControl. Get advice and tips from experienced pros sharing their opinions. Updated: June 2025.
857,028 professionals have used our research since 2012.

For how long have I used the solution?

I have been using Kerio Control since the late nineties when it was called WinRoute Firewall.

What do I think about the stability of the solution?

The stability is really good. I haven't had any issues whatsoever. 

What do I think about the scalability of the solution?

I'm not a large enterprise, so I don't know how well it scales. But I imagine if you were to throw bigger hardware at it, it would scale really well.

I'm the owner, so nobody else touches Kerio except for me. Everybody else uses it as part of their job. They don't really know it's there.

My company is small-sized and Kerio is good for it. It's good for small and medium businesses. I've never used it on a large or an extra-large enterprise, so I couldn't give my opinion on that. I would imagine it could, I just don't have any experience.

How are customer service and support?

I haven't used GFI, but back when Kerio had it, they were very good.

They were very responsive. A lot of times you call the company tech support and they want to treat you like you don't know what you're doing. It's a "Is the power plugged into the wall" kind of a thing. They're very fast to understand that it's not the user that they're talking to on the phone. That the user they're talking to on the phone knows what they're doing to an extent and needs some extra help. It saves time. But I haven't had to call GFI yet, other than when my key wasn't working. It was an email. When I renewed my subscription, the keys didn't update. They had a problem with their update process, so the person had to go and manually update all my subscriptions. It took a few days. 

At first, they didn't understand, because they said it's just automatic. Which it's supposed to be. The next day I told them that it didn't update. Then finally looked and they did one subscription, and then I told them that my other subscriptions didn't update. 

At first, I was supposed to read a manual on how to do it. But I was doing everything that was shown, it just that their process behind the scene wasn't working. It's the online thing, so it was updated. However, my server wouldn't get the notification that it was updated. They thought I was not doing the website properly because they would tell me to go to the website and hit update. It first started as if I was a user that didn't know how to do anything and then they realized we had a problem. I fixed it. It should have been a lot faster.

Which solution did I use previously and why did I switch?

I did try out another solution called Unify but it wouldn't work very well. I couldn't get the VPN tunneling to work. The GUI was not intuitive and it was all over the place. Things were not all in the same spot. 

I actually bought several of them. I was going to go away from Kerio. I didn't like the way Unify worked. You had to have a gateway key in order for it to work. You took two devices to make one device work. I ended up scrapping that project and kept Kerio.

How was the initial setup?

For the initial setup, it walks you through a wizard. I've just never used that. But the wizard can set up a very basic bare bones, don't let anything in kind of a setup, which works. My setup is more complex. I have VPNs and tunnels. Any IP on my network has to be logged in, in order to get out. Mine is more of a complex setup. The ease of setup is pretty easy if you use the wizard. It just asks you a few questions and that's it. It's a bit more complex when you do it yourself. 

The deployment took a couple of hours. 

What was our ROI?

I have seen ROI. All the attacks, malware, and viruses that have been stopped are nonstop. The people out there are attacking all the time. It's nonstop, it never stops.

We have peace of mind that our solution stops all those attacks.

What's my experience with pricing, setup cost, and licensing?

Get the GFI unlimited, unless you're only going to have it at one spot. The pricing for the unlimited is a pretty good deal.

Which other solutions did I evaluate?

I looked into Palo Alto, that had a lot of features and everything else. But when I tried to contact them to get a price, they didn't give me the time of day. They wouldn't even return my call. At the time I was a director for a very large company and they still ignored me.

What other advice do I have?

Make sure the person that's doing it knows what they're doing. If you're not getting overly complicated, pretty much anybody can do it. But if you're going to get complex, you'll need to have somebody that knows their way around or else you might make yourself vulnerable.

If you have a tunnel and you have to change certificates because they expired, you do it in the right order, or else you might have to travel long ways to accept the key on the other side. If you create a new key for the tunnel and apply it, the tunnel is down until the other side accepts the key. If going through the tunnel was your only way there, then you're now traveling unnecessarily or long ways. Luckily for me, it was not too far away. But if you have city to city and you have no one on the other end that has the ability to log in and accept the key, then you're going there.

I would rate Kerio Control an eight out of ten. 

I haven't had a lot of experience with the new owners and I'm worried that they're going to sunset it or not give it the attention it needs. That's just my thought, I have no proof or anything like that.

Gives me the ability to map which ports to allow in and out of the VPN
Pros and Cons
  • "I want to have access to my computer from the outside and Kerio Control plays a role because it has a VPN... It is more reliable because it's a smaller group of computers to target for hackers and the like. The VPN works very well. I use it to work remotely very easily and exchange information, both to and from the location where it's deployed, and there have been no problems there."
  • "I would like to be able to automatically send email from Kerio Control and have it tell me what my external IPs are, because on one of my lines I have a fixed IP address and on the other it is variable. If there were a permanent way for me to figure out, "Okay, my current external VPN and my firm IP is this," it would help. I need to know the IP address to connect with the VPN and, at the moment, one of the lines sometimes changes its IP address without me knowing it. It's a hassle to figure out what it is."

What is our primary use case?

I use Kerio Control because it is one of the few firewalls which allows easy failover from two separate internet providers. It also has virus protection built-in. I use it to have reliable access to the internet, which is virus-free and which fails over if one of my internet providers drops — and they do sometimes when it rains. Those were the reasons I wanted Kerio Control. And it just works; provides internet.

We are a very small company, and started with two users. We have now four users who use it on and off. There are nine or 10 computers. I, myself have three or four computers working at the same time. I'm not really dependent on cloud, but I use internet very much in a lot of situations.

It's deployed onsite but as a virtual machine in a Windows server.

How has it helped my organization?

Being an SMB, Kerio Control is nice-to-have. It fulfills my needs completely. 

It allows the users I have to use email without any problem, without their having to know anything about the fact that there is a firewall which protects them in different ways. I might spend an hour per month on maintenance of the Kerio system. So it's very transparent and very hidden. The best thing is the fact that nobody notices it.

It has helped me save time. It allows me to get on with my main work, without spending any time on security or worrying about threats to the data I have. Without it, I would have lost a lot of time. A long time ago, I spent a lot of time cleaning computers, removing viruses, etc. That has all gone away since I have had this set up, as part of a three-layer defense.

The failover has no effect on security. It only affects the availability. There used to be a situation where I had two internet providers with different speeds. If my main provider was down, it would be backed up by the other and I wouldn't notice that it was a little slower, and I wouldn't notice that one of my internet providers was unavailable. This guarantees that I always have internet availability. We had some technical problems with one of the lines which was very sensitive to rain — which sounds weird, but okay. And this setup allowed me to not think about it anymore. Since then, internet speeds have grown and at the moment it's not a big issue, but I'm sure that both of the providers drop once a year for a day. But I don't notice it, and that's very important for me.

What is most valuable?

The most valuable features include 

  • being able to attach to two different internet providers
  • the ability to map which ports you will allow in and out of the VPN, which is built-in 
  • the fact that it reliably works without any attention.

I want to have access to my computer from the outside and Kerio Control plays a role because it has a VPN. This VPN is different from most other VPNs, although they have used a standard version. It is more reliable because it's a smaller group of computers to target for hackers and the like. The VPN works very well. I use it to work remotely very easily and exchange information, both to and from the location where it's deployed, and there have been no problems there.

I have one or two VPN clients, at most, that are active at one time, so it's there if needed when I'm not working at this location. It helps me a lot to have a reliable VPN client. I have no performance issues when working through VPN.

Kerio Control also has some authorizations so I am able to block internet access for certain hours for certain people.

Overall, the security features are adequate. They do what I need. I don't have much experience with anything else, so I can't compare, but they completely solved my problems.

The firewall and intrusion detection features don't hinder me, and I haven't had any attacks, as far as I can see. I want a firewall to be unobtrusive. I don't want to notice it's there. It should just do its work and protect me and not hinder me when doing real work, and that's what it does. It's very good because it shouldn't be noticed, and it's good at not being noticed and doing its work.

Overall, I don't have any problem using Kerio Control. For me, it's very easy, but I've been working in software for some 50 years.

What needs improvement?

I would like to be able to automatically send email from Kerio Control and have it tell me what my external IPs are, because on one of my lines I have a fixed IP address and on the other it is variable. If there were a permanent way for me to figure out, "Okay, my current external VPN and my firm IP is this," it would help. I need to know the IP address to connect with the VPN and, at the moment, one of the lines sometimes changes its IP address without me knowing it. It's a hassle to figure out what it is.

It might also be interesting to have a GFI-approved, Docker-containerized version of the Kerio Control system.

For how long have I used the solution?

I have been using Kerio Control for more than 10 years.

What do I think about the stability of the solution?

I don't remember any glitches. I haven't had problems with it for a very long time. But I use it very specifically for a certain purpose and that works fine.

What do I think about the scalability of the solution?

It's very hard for me to give a correct estimate of the scalability, since a lot of overhead in my situation is caused by the fact that I run it in a virtual machine. That means the bandwidth which it can process, which would be scalable, is downgraded because it's in a virtual machine. That's not Kerio's fault.

I have no plans to increase the usage in the future. For me, it's adequate because I have a lot of leeway. I have enough bandwidth available to fulfill my needs.

How are customer service and technical support?

The problems I've had with Kerio, when I wanted to change something, have always been solved by consulting the Knowledge Base.

We are located in Holland and there is supposed to be Dutch tech support, and there is an American tech support, as far as I know. The bad thing about the American tech support is that reaching them by phone is difficult and by mail there's a certain turnaround. So, I'd rather rely on the Knowledge Base so that I'm not really dependent on the person on the other side.

They have an extensive Knowledge Base and, if you can't find something there, you can check the internet and there's enough available.

Which solution did I use previously and why did I switch?

I switched because I wanted something which had the possibility to handle two different internet providers, two network cards, and do load switching and load balancing. The other solution I used didn't have that.

How was the initial setup?

The initial setup is easy. I know what I want to configure so it's easy, no problem at all. 

The biggest problem I have is using it as a container on a virtual machine. You have to connect your hardware network cards to the internal virtual machine. That's a problem that Kerio won't be able to solve because it's the environment I have to create to let Kerio work in the way I work, and that is probably different than most users. But if you use it on a simple PC, it's no problem at all.

I reinstalled it recently and it took me about half an hour, and part of that was getting backups right, etc.

As for an implementation strategy, I changed the system my Kerio was installed on, so I first did a trial-install to figure out if everything worked. After that, when I did the actual production install, it was done very fast because I had tried it out before.

What was our ROI?

It does its job. Converted into hours, it doesn't cost more than five hours per year to pay the price for the 10 users I have. That's a good deal for me.

Having good internet access is a very large requirement for me to do my work. Internet is one of the basic tools I have and I need a firewall. Your internet provider will give you a box that has a simple firewall in it, but that doesn't suffice for me. I need something like this and it's not an option for me not to buy a product like this. I'm really not even thinking of return on investment. If I don't have something like this, I just can't work. It's a basic necessity.

What's my experience with pricing, setup cost, and licensing?

I don't think it's expensive. I'd recommend it to others.

Which other solutions did I evaluate?

I haven't evaluated any other options. I started using Kerio Control and it was sufficient. I haven't spent any time looking at alternatives. I've seen constant improvements in Kerio; they actively enhance the product. That's a good sign for me. I also use the GFI mail server and I prefer to use one company for my tools.

What other advice do I have?

My general advice is always: Read the manual, check your hardware and see if you have everything you need, and if it will suit your needs.

It's hard for me to assess its malware and antivirus protection because Kerio is one part of a three-part defense against malware and antivirus. I'm not sure which part picks up which problem. My philosophy is that no single protocol picks up all the problems, so if you have several of them, you'll fight the virus or malware at some point. That's why I have three different tools with different focus points, and together they keep me safe. Malwarebytes specializes more in malware, ESET is a normal desktop antivirus system, and this system is a general anti-malware and antivirus system of another type. They compliment each other.

I have an internet speed of 200 megabits per second, and 15 might be enough. So the only point I don't know about Kerio is whether it takes a lot of performance out of the maximum you could get if you didn't have a firewall.

Overall, I would give it a nine out of ten, but with the comment that I haven't compared it with anything else. On my scale, 10s are very rare. They're for things that go beyond my expectations and Kerio does exactly what I expect and it does it well.

It's just an essential which does it's work. I don't think about it normally. It's just there and it works.

Which deployment model are you using for this solution?

On-premises

Makes it easy to manage and add settings to the firewall, and gives us a single point to manage global rule sets
Pros and Cons
  • "The traffic insight page or the administrative portal is really helpful because you can see all the internet usage down to the point where you can see if it's big files or streams. It gives us a good view of what the internet usage is of users who are coupled to an IP address. That way, if there are problems with, for example, a lot of data usage or problems with the connection, we can narrow it down to a single user or server and address the problem. It's really helpful for diagnostic data."
  • "If you have to dive deeper into the firewall or any other features, then you really have to read up a bit about how to set it up properly. Some of my colleagues, in the beginning, jumped in and made a bunch of rules but then it got really messy. If Kerio had a template or guidelines for best practices, at the beginning, that would really help. With Kerio Control it's basically 'find out for yourself.'"

What is our primary use case?

We mostly use Kerio Control as a virtual firewall solution, and the user accounts let people have access to the internet through the firewall. We also have a few cases where we use the VPN. But it's mostly a firewall solution with multiple VLANs and the network behind it.

It's deployed on-premises, both virtual and hardware solutions. The NG100 is the smallest solution for smaller businesses, but we mostly use the virtual appliance.

Most of our customers are small to medium companies, where there are between five and 40 work spaces. Everyone has a PC and they have a VoIP phone and their own phones, and they have tablets. Most of the time, it's one to four devices per user. The biggest client we have is around 30 users.

How has it helped my organization?

It has made it easier for us and our employees to manage and add settings to the firewall, as opposed to another brand where you have to use command-line or really complicated layouts. The ease of use is a big plus.

The solution has also saved us a lot of time in managing security. We have to adjust the content rules and now we have one place where we can enter them. We have a customer with about 20 Kerio Controls and we don't have to set all the rules on each firewall. When we have to add some rules to each of the firewalls, it can be done within one minute. Normally, it would take 20 to 30 minutes, depending on if they're all online — and we would have to check them manually. Now, we just have to enter them and, when they come online, they sync with the global rule sets.

What is most valuable?

The traffic insight page or the administrative portal is really helpful because you can see all the internet usage down to the point where you can see if it's big files or streams. It gives us a good view of what the internet usage is of users who are coupled to an IP address. That way, if there are problems with, for example, a lot of data usage or problems with the connection, we can narrow it down to a single user or server and address the problem. It's really helpful for diagnostic data.

The content filtering is pretty good for our needs, especially with the global rules you can define. We can define global rules and use them on multiple Kerio Control installations. So we have one place to set all the rules for different customers. That's very good. The rules that it auto-updates and that are automatically available — for example, spam or indecent websites, or whatever else is in the firewall by default — are good.

The VPN works pretty well, especially with the Kerio Control VPN software. Some products don't have their own VPN software and, with Windows, sometimes it's just better to have a piece of software. That's especially true for some of our customers because they only have to open the software and press "Connect." Windows can be a little bit weird when it comes to that, and it breaks connections. You really don't see when Windows loses a connection or if you have to reconnect. The Kerio Control VPN client is pretty good at that.

What needs improvement?

The antivirus is either on or off, but we can't really see or measure how well it is doing. Sometimes we get the feeling that some files get past it and then they get caught on the antivirus of the client PC. We would like to have more control with the antivirus.

Also, we have multiple employees working on firewalls and if one employee changes a rule and traffic that shouldn't be there suddenly comes through the firewall, it's hard to pinpoint which rule is affecting that traffic because there is some overlap. It's not clear if it's getting past it because it's not decrypted. It needs more logging or more in-depth diagnostics about which traffic is hitting which rule on the firewall. Sometimes we have 20 or 30 rules and it becomes a whole job to figure that out.

When it comes to QOS, the quality of service, you have to set a fixed bandwidth. But sometimes, when we have multiple connections in front of it, it's a fallback line. For example, when we use Kerio aboard a ship, there is the satellite connection but there is also a 3G or 4G connection. We always have to set a fixed limit for the connection. If we set the fixed limit to 4G and it switches to navigation, one user can use up all the bandwidth for the entire ship. It would be better if there were something more dynamic, where it could sense the total and we could use percentages. For example, we could say a user has always 5 percent of the connection. But now we have 5 percent of a fixed connection number. The fixed limit on a line for QOS is a problem because we don't always know which connection is in front of it.

Also, if you have to dive deeper into the firewall or any other features, then you really have to read up a bit about how to set it up properly. Some of my colleagues, in the beginning, jumped in and made a bunch of rules but then it got really messy. If Kerio had a template or guidelines for best practices, at the beginning, that would really help. With Kerio Control it's basically "find out for yourself."

We've also had some problems with how to set the rules, but that's when more than one rule is overlapping and cancels out all the other rules. However, that's more our fault.

For how long have I used the solution?

I have been using Kerio Control for around six years.

What do I think about the stability of the solution?

It's pretty stable. We had some problems with Kerio Control virtual appliances. If it was running more than 20 days, it would become really slow and sometimes it would just stop working. When we rebooted the solution it would come back up. But that was something that was happening a year-and-a-half ago. Since then, we haven't had any more problems with it. 

We had a few solutions that just went corrupt. We're not sure if that was the disk or Kerio itself. We always have an installation of the virtual appliance on the server, so we can set up a new one, load the backup back in, and be up and running again in 15 minutes.

How are customer service and technical support?

It's been a while since we contacted support, but back when we did it was pretty hard to get a hold of someone. We didn't get a lot of feedback. Most of the time, it was, "Look at the documentation." It was hard to get someone to look over our shoulder and help us with the problem. I think that was before GFI took over.

Which solution did I use previously and why did I switch?

We did not have a previous solution. 

How was the initial setup?

As I said, if there were best practices or a template, the setup would be a lot easier because you start and then you change the setup according to what you think is right. But later on, when you encounter problems and look in the documentation, you see that another way is better. That was a bit of a problem when setting up. It all works, but in managing or adding rules, for example, or we just didn't do it properly. It was a bit of trial and error and that was a problem. It's too much trial and error when you start.

Deployment time, for some customers, is fairly quick. A basic setup can be up and running in 15 or 30 minutes. With other customers that have a lot of rules we do testing so it could take three or four hours.

For our implementation strategy, we just look at what the client wants. For some clients, we have a basic template now, where we always use a backup from an existing Kerio. If it's a new customer, we check if we have an existing Kerio that's pretty much the same, or we just do it from scratch if there aren't too many rules or networking behind it.

What was our ROI?

We see ROI because the ease of use is a lot better, so we spend less time on maintenance, administrating, changing rules, and checking usage.

What's my experience with pricing, setup cost, and licensing?

If you have a lot of users, the licensing can be a bit of a problem because we have a lot of customers who don't use the user feature, but we have five devices per user, and we have to extend the license every time. The fixed model of users and devices is a bit of a problem for us. We want to be able to expand it fast and not have to contact our supplier first to get a license. That takes another one or two days and the customer is waiting.

It might be better if they offered a fixed monthly or yearly price instead of the user-based price. That's really keeping us from deploying with some of our smaller customers or customers that have a more dynamic user base. If they had a larger fixed price with unlimited users or devices, that would help. Now, it's five users each time. A pack of 100 or 200 users for a certain price would make it more dynamic and user-scalable.

Which other solutions did I evaluate?

We looked at pfSense and some paid firewall solutions, but in terms of how user-friendly it is for our employees and my colleagues, and how well we could manage it from a remote portal, Kerio Control was better, in our opinion.

What other advice do I have?

Kerio Control is a nice-to-have for a small business like ours.

My advice would be to look at best practices or get someone to show you how to properly set it up before you try anything and it gets too messy. The biggest lesson I have learned from using this solution is to look out when it comes to firewall rules. Don't use too many firewall rules or content rules because it can get really messy, really quickly, if you don't have a decent strategy for that.

We always try to use auto-update, so most of the time we're on the most recent version. We have some examples where we use Kerio Control aboard ships where the bandwidth is really limited. In those cases we use our own timeframe to update Kerio Control, but it's normally done within a month or two, so most of them are up to date.

We haven't seen anything yet in the antivirus and we haven't had any problems with malware with our systems. I don't know if malware is being detected that well, because sometimes the clients still have some malware. I don't know if it's because it's an HTTPS site or something else.

In our company, most of the work with Kerio is done by about 10 people. Everyone does the same tasks: administrating, changing rules, and installing new Kerios. I work on it in my role as a system admin team lead and developer. As of late, I've been more of a developer than administrator. The others are system administrators, business consultants, and there are two other developers.

VPN enables us to do remote work and we can better manage security
Pros and Cons
  • "We also like the security. We can control what sites users can go to and we can make sure that where they're going is appropriate and that it's work-related."
  • "The denial of service could also be improved. There recently was a big issue with denial of service attacks and it was a bit laborious."

What is our primary use case?

Our primary use cases are for internet connectivity, security, and VPNs.

How has it helped my organization?

The VPN connections have improved my organization. It also means that I can manage security more easily.

What is most valuable?

The most valuable feature is the VPN. It enables us to do remote work. 

I use the geo IP filtering a lot. 

We also like the security. We can control what sites users can go to and we can make sure that where they're going is appropriate and that it's work-related.

What needs improvement?

Quality of service and bandwidth management need improvement. It just doesn't seem granular in that.

The denial of service could also be improved. There recently was a big issue with denial of service attacks and it was a bit laborious.

For how long have I used the solution?

I have been using Kerio Control since 2016. 

What do I think about the stability of the solution?

It's stable and we rarely have any reliability issues.

What do I think about the scalability of the solution?

It is scalable up to a point that then you might have to use a user faster, bigger one, but on the whole, it is scalable. It's because based most installations I have are over 300. Whereas if they start to get really big, you'll need to increase the model to the next model up.

In my company, it's me that manages and installs them all. We install, manage, and offer basic management and support.

The environments we've installed for can go from three to 50 users.

We've never had any problems with it not being able to manage the traffic.

How are customer service and technical support?

The GFI technical support is average. The speed of response sometimes is not very fast. Sometimes they take a while to resolve an issue. For example, I've got an issue that's not been resolved for three months now, meaning that the box, the unit isn't performing as it should do.

Which solution did I use previously and why did I switch?

My clients generally replace solutions like SonicWall and Fortinet with Kerio but sometimes they don't have a firewall at all, so we set them up with their first firewall.

It's easier when all our customers are using the same firewall. It makes it easier for us to manage them across the board. We use Kerio across the board.

We used to use a lot of Fortinet but now we've replaced that with Kerio because of the support and price, although now the support is not so good. The price is fair and the features are all pretty much the same.

How was the initial setup?

The initial setup is straightforward. It's a bit tricky because I do it a lot, but it's pretty straightforward. It has a Wizard if you need it, but I don't need it anymore. I know what I'm doing. I find it quite easy to set up.

A basic deployment takes an hour. Just the box standards are set out for everybody, and then if they need something specific, we'll add it in afterward. But a straightforward, standard, basic setup takes about an hour.

We have a unified implementation strategy that we start with and then we tweak it if need be. We don't use MyKerio to put a standard implementation across all of them.

Our standard implementation strategy is to implement dual internet connections, standards, and standard traffic rules with VPN access.

What was our ROI?

At the end of the day, our customers are being managed, looked after, and they're secure, so they're happy.

What's my experience with pricing, setup cost, and licensing?

The licensing is a bit of an issue. People don't like to have to buy user licenses. They think they should be able to buy the box and be able to use it. Licensing is a bit old fashioned in terms of the fact that if they don't renew the license that box becomes useless. People really don't like that. Then they can't use it anymore.

What other advice do I have?

My advice would be to make sure you've got an internet connection. The first thing you have to do is register the user on the internet and then if you get to a new installation where you're setting them up from scratch, you're going to struggle because with the new Kerio unit, the first thing it needs to do is connect to the internet and it can't do that if you haven't set it up. It's best to get it set up before you install it on site.

The biggest lesson I have learned from using the solution is not to assume everything is running okay because it might not be. The main reason is because of the denial of service not being up to scratch. You have to make sure that their connections aren't being kept of denial of service effects. That's the problem right now. I would say denial of service is probably one of the weakest areas.

I would rate it an eight out of ten.

If one connection goes down, it automatically switches for me
Pros and Cons
  • "The routing of the multiple internet physical routers I have is the most valuable feature of this solution. Instead of me physically unplugging a cable from one router to the server, if one connection goes down, it automatically switches for me. So I can have all three of them plugged in. If one goes down, it just picks up the other one automatically. There's no physical cable swapping."
  • "I would like it if the interface section had multiple failovers. Although I do have three connections, just in case our physical cables get disconnected, I can only set up one failover as a backup. So, if for some reason our fiber and our AFM went down together, I would have to have it search for our 4G modem. I'd love to have extra backups running."

What is our primary use case?

My primary use case is to route traffic and route our multiple Internet interfaces. It routes all of the outbound Internet traffic, none of the internal. I do apply a content filter as well to make sure people aren't going into places that they shouldn't be. We have some traffic rules setup for certain services, blocking certain IP ranges from getting external access as well. We do the same for the Adelaide office, but our South Coast office, in addition to all of that, we also run DSCP off of it. The South Coast is the only place we use the DSCP on Kerio.

How has it helped my organization?

Now that we're both running fiber connections between Sydney and Adelaide, I can access our document server in Adelaide just from my PC, rather than using something like TeamViewer and transferring the file I'm after via TeamViewer from Adelaide. I get to it not much slower than the internal server we have right now. It's fantastic.

What is most valuable?

The routing of the multiple Internet physical routers I have is the most valuable feature of this solution. Instead of me physically unplugging a cable from one router to the server, if one connection goes down, it automatically switches for me. So I can have all three of them plugged in. If one goes down, it just picks up the other one automatically. There's no physical cable swapping.

In terms of ease of use, it's pretty easy. It took some playing around for me to understand some of it, but I'd say if you understand what it is you're after, and how that works, then this is pretty easy.

We use the firewall. It's fine, a bit tough. I need to test it against others. I'd rather use the Kerio firewall than the Windows ones.

With the VPN features we can connect all three of our sites together.

The content filtering and VPN features are pretty easy to set up. It's a couple of clicks and it's done, so it's pretty good. I'm pretty happy with it.

I am the only manager who manages the security. It does save me time. In the scenario where one Internet connection goes down, I used to have to run to the server room and unplug a cable, and come back. Now, I don't have to do that at all. It saves me a lot of time, 100%. With the routing, previous to this there are a few things in here that I haven't had the ability to really do how I wanted so I don't have a comparison.

What needs improvement?

I would like it if the interface section had multiple failovers. Although I do have three connections, just in case our physical cables get disconnected, I can only set up one failover as a backup. So, if for some reason our fiber and our AFM went down together, I would have to have it search for our 4G modem. I'd love to have extra backups running.

Someone set a printer to have a static IP address and because they set it as static, it won't show on my LAN, on the DSCP server, because it's not questioning it. So just because the device does not request the rules from the DSCP, I don't see why it wouldn't show up in my LAN on the DSCP server. That's a bit odd. It's different from how a Windows DSCP server would react. Instead of only showing one is requesting DSCP, or on a reservation, it shows all, whether they're reserved or not. A Windows one would. For some reason, it isn't showing me ones that were statically assigned.

For how long have I used the solution?

I have been using Kerio Control for four to five years. 

It's deployed in three different locations now. 

What do I think about the stability of the solution?

The stability is pretty good. I've only had one issue with it before. It was set to update on its own, and it didn't update and the update failed, so it didn't come back on for some reason.

If an update fails, it should have some kind of automatic rollback to bring itself back on. Because when it does that at night and it stops, I don't really get a notification that it's stopped. It's not on anymore so I don't find out that nothing has worked all evening until the next morning.

What do I think about the scalability of the solution?

Scalability is fantastic. I don't see a limit to it.

I am the only admin for this solution.  

We employ a company that contracts stuff out for me, so they're the people that initially installed this for me at the three sites, but I maintain it. If I have other things I don't know how to do, they'll get in, but it's just me and that other team.

Increasing usage depends on whether the business itself acquires other businesses, and that's really why we've got these three locations. We bought a business in Adelaide, so we set up a similar setup to what we had in Sydney. And this year in February we bought another business down in the South Coast of New South Wales and we've set up a similar thing there as well. So if we buy other businesses and I need some other help with the server running, then yes, I'll probably get another license. But only if that happens.

My business is medium-sized and this solution is perfect for it. 

I have one point of access for multiple portions of what I need for routing. We've got an Internal server that's managed by a different company and it was incredibly easy for that other company to put certain rules in place and then for us to create those rules to and communicate to the outside world was incredibly easy to map. There was just no confusion between the two companies that we're talking about what to map. That was in the initial setup, so that all wasn't done by me. They just communicated to each other very easily. This made it very simple. There was no confusion.

How are customer service and technical support?

I've never contacted technical support because I just call the people that I contract to fix things and if they're not quite sure how to fix something, they'd probably contact GFI. 

Which solution did I use previously and why did I switch?

We used to use a Cisco router. That was it. There was a very limited amount of routing I could really perform.

Kerio Control enables us to add multiple routing. We have lots of different options in the one thing. 

Kerio was recommended to me by ITIS. They told me that this one was what they highly recommended we use for what I needed.

What about the implementation team?

The outsourced contractor that we used for the setup was great. There's nothing wrong. I've been using him for a while.

What was our ROI?

I can't imagine not using it. I think if I had to use the Microsoft server to do all of this I'd be very frustrated.

What's my experience with pricing, setup cost, and licensing?

I don't have other ones to compare the pricing to. I haven't used other solutions to know all the features they have. The price seems reasonable to me for something that does so much and works so well.

What other advice do I have?

Kerio Control has not increased the number of VPN clients but we have added clients only because they needed it, not because Kerio is there.

To the best of my knowledge, before Kerio we did not experience a security breach. The only semi security issue we had was that someone had run a virus that encrypted a whole bunch of files on the server. But that was before my time. I was not the IT manager at that point.

If I didn't have the help from someone else that completely understood all of the services that are features of this product, then I probably wouldn't have put it in myself. It's definitely more advanced for people that are handling this type of networking day to day, which I don't. The only other thing that I've had a problem with is Apple servers for some reason, because Apple services come through on so many different servers themselves, and different destinations on the Internet, there's always some kind of issue with updating them on the network with Kerio running. I don't know why. It's just Apple. Everything else is fine.

Personally, I've just learned how to route traffic over a network well. It's helped me to route different parts of the Internet to different parts of my network, which I can't do on a Window server, and visually it's been a great help.

It's been able to add multiple Interfaces, it's good. I have multiple Internet streams and a failover. That's the best.

I would rate it a nine out of ten.

Scales easily, works well, and has good content filtering options
Pros and Cons
  • "The firewall and the content filtering options are valuable."
  • "There isn't a lot to be improved. It works well as it is, but they can maybe improve the reporting side."

What is our primary use case?

We use it for our data plan. We are using its latest version.

What is most valuable?

The firewall and the content filtering options are valuable.

What needs improvement?

There isn't a lot to be improved. It works well as it is, but they can maybe improve the reporting side.

For how long have I used the solution?

We have been using this solution for about five years.

What do I think about the stability of the solution?

It is pretty stable. We don't have any issues.

What do I think about the scalability of the solution?

It scales easily without a challenge. We have about 400 users, but administrators directly work with it.

How was the initial setup?

It was pretty straightforward. It took about an hour.

What about the implementation team?

We deployed it ourselves.

What's my experience with pricing, setup cost, and licensing?

Its licensing is yearly. You renew every year. Its price is all-inclusive.

What other advice do I have?

It works well. I don't have a problem with how it works. I am also fine with its deployment, but it can be challenging if you don't have someone skilled or trained. If you have the skills, its deployment would be straightforward. You would be able to deploy it without a challenge. So, you just need to find the right person to deploy it.

I would rate it an eight out of 10.

Effective ISP feature, stable, and simple deployment
Pros and Cons
  • "The most valuable features of Kerio Control are the IPS and traffic rules. The traffic rules are very user-friendly and the IPS is working well. Additionally, the anti-virus is effective with quick options, such as filtering."
  • "Kerio Control could improve by having higher availability and adding a mobile VPN channel. These additions are needed. The VPN is working fine on the Kerio Control but there needs to be a VPN client on the mobile phones, both for iOS and Android. This would be very good for us."

What is our primary use case?

We are working with VMware and we are using virtual machines for Kerio Control.

What is most valuable?

The most valuable features of Kerio Control are the IPS and traffic rules. The traffic rules are very user-friendly and the IPS is working well. Additionally, the anti-virus is effective with quick options, such as filtering.

What needs improvement?

Kerio Control could improve by having higher availability and adding a mobile VPN channel. These additions are needed. The VPN is working fine on the Kerio Control but there needs to be a VPN client on the mobile phones, both for iOS and Android. This would be very good for us.

In a future release, SD-WAN features would be very useful.

For how long have I used the solution?

I have been using Kerio Control for approximately seven years.

What do I think about the stability of the solution?

The solution is stable. However, we have had some problems, and we want to receive some updates for the IPS module. Sometimes we have errors downloading the IPS updates.

How are customer service and support?

I have not contacted technical support. When I have an issue I search the internet and solve the problem. When I search Google, I find solutions for my problem.

Which solution did I use previously and why did I switch?

Previously I was using OPNsense and pfSense. However, Kerio Control is more user-friendly and stable than pfSense and OPNsense.

How was the initial setup?

The deployment of Kerio Control was easy and user-friendly. We have no problems deploying the Kerio Control, Kerio Portal, and Kerio Connect for our customers.

What's my experience with pricing, setup cost, and licensing?

I am living in Iran and we cannot buy the product from Kerio because of sanctions.

What other advice do I have?

I rate Kerio Control an eight out of ten.
