A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Comprehensive Security Features and High Ease of Setup Elevate User Experience
The best features for KerioControl are its proprietary VPN protocol, which does not connect easily with other firewalls unless you enable IPsec. It will only connect to KerioControl. KerioControl is very valuable for business. Key points where KerioControl is valuable include its own anti-spam, intrusion prevention, and antivirus, which is included in the yearly subscription renewals. The VPN capabilities are helpful in managing my remote or distributed workforce, as we create documents and set up a location for clients to download. Clients can download KerioControl's VPN client online, and they just have to log in from the VPN client, which connects easily. I assess the firewall function in filtering both incoming and outgoing network traffic with KerioControl as excellent. Everything is logged, and any intrusion, antivirus, virus, or anything foreign to the system trying to hack in gets logged, and we can easily block those IPs.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is secure."
"Unified Threat Management (UTM) features."
"The best feature of Fortinet FortiGate is its SD-WAN capability, which is included and differs from other products that require an additional license."
"The usage in general is pretty good."
"The most effective features for threat prevention are the IPS, content filter, and SD-WAN capabilities."
"Security solution with a straightforward and quick setup. It's a stable and scalable product."
"With Fortinet FortiGate, we improved security significantly."
"Fortinet FortiGate has SD-WAN, FortiView, antivirus, sandbox, and IPS, which are generally well-known features."
"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 flexibility of the system, the capacity to provide the right level of security, and the ability to be integrated into different kinds of infrastructures are the most valuable features."
"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."
"It prevents people from visiting undesirable sites and ensures that they use the internet for their designated jobs."
"The interface control manager where we can allocate LAN connections to certain VLANs is the most valuable feature. The other feature that's important for us is because obviously everything is remote with MyKerio, as long as the boat has an internet connection, we can log onto the Kerio and get statistics, as well as provide support."
"The top features are ones that we're not using yet but we soon will be because we've just had broadband upgraded in Australia. We've got something called the National Broadband Network, which is forced onto you, so you have to take it when it arrives. We'll be trying the high availability out soon. We tried that with some load balancing, it didn't quite work as we expected, but I think that was more of a configuration thing rather than a product thing."
"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."
"It has saved a lot of time and it was a secure way of doing it too. We had a whole contact center that worked from home for a period of time and that's a 21 hour a day contact center that we moved, that was spread out across the greater Brisbane region and working on home internet connections. Surprisingly, we didn't have a lot of stability issues anyway on those connections, but Kerio didn't blink, so that was good."
"The app inspection is very helpful for network security."
"The stability of Palo Alto Networks CN-Series is excellent."
 

Cons

"The solution’s stability could be improved."
"I would rate Fortinet support a six out of ten. The immediate response is not that good, particularly when raising a critical or P1 ticket; they lag in the immediate response."
"Fortinet FortiGate can improve by integrating the web application firewall and the DDoS protection part of the solution. Having a WAF feature, web application firewall, and proxy together would be a good benefit."
"The performance can be improved."
"The logs need to be better. They need to be more visible and easier to access."
"It could use more templates for third-party site-to-site VPN setups other than FortiGate and Cisco."
"Fortinet needs more memory to save the log files. We need it to save the logs on the hardware and not in the cloud. I know this feature is available in FortiCloud, but if we need this log locally, it is not available."
"One point against them is that their solution lacks a unified approach."
"We'd like to have more integrations Kerio Operator."
"The antivirus seemed to be a bit laggy on the connection so I disconnected that. It's definitely good. The only issue we've had with any sort of cyber attack seemed to be coming from a couple of distinct locations, people trying to get into known ports on remote desktops and stuff like that. The fact that we can block all that traffic is just great. It simplifies it."
"I would like to see them develop a bit more flexibility creating VLANs."
"The VPN features are the ones that we really like, but we are using a VPN client to be able to use them. We would like to have an SSL implementation for this same feature so we don't need to install anything on the client side. That's a feature I really miss and that should really be embedded in the product. We really would love to use it via a web browser."
"The upgrades make the network slower."
"The security part of the software, like virus scanning, website, traffic monitoring, things like that, can take a beating on the appliance. And when there's a lot of things going on, the system can get bogged down. The actual security functionality of it needs a little bit more work, which I believe they are remedying or attempting to remedy at this time, but that's the downfall at this time."
"I would like to see geo-IP filtering added to the filtering rules. Incorporating these rules would be very beneficial if you have different ideas or reasons to filter, such as communication to the email server or specific websites."
"The GUI should be changed because it remains the same consistency across versions. However, those who have been using KerioControl for a long time may be accustomed to the current interface. Installing a new version in the same location makes it easy to find, but overall, there are no notable changes between versions."
"I'd like to see more IOPs features."
"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."
 

Pricing and Cost Advice

"The pricing is justified. It's a little pricey, but what you pay for is what you get."
"I would rate pricing to be about four or five out of ten, it is reasonable."
"If we have an older version, the support costs get quite high."
"Its price could be better."
"I pay €1,200 per year for the license along with Fortinet's 81E firewall appliance. I would rate this pricing as 3/5 stars, and I believe the price is reasonably similar to its competitors in the market, being somewhere in the middle."
"It's an expensive solution."
"For our organization, the licensing costs are approximately $7,000 per year."
"Setup costs and pricing depends on many variables, but it's mostly affordable."
"Pricing is good, but the licensing took a lot of time."
"Its licensing is yearly. You renew every year. Its price is all-inclusive."
"It's very affordable."
"Its price is fair. There are no additional costs."
"The price of Kerio Control could be better, it is a bit overpriced compared to other solutions."
"It's pretty expensive in licensing costs, especially if you use the product longer than one or two years. The licensing costs are still high, which I don't think is reasonable for a product like this."
"It gives us a lot. It does prove to be a very robust product for the cost."
"It is a good fit for SMBs because of its maintainability. When you want to keep your costs low, then Kerio Control is a very good solution. It's not an expensive product that is well integrated. It has a complete set of features within it that make it a very strong product."
