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.

Is stable and has a user-friendly dashboard and a good interface
We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good We cannot secure a specific IP class with this firewall. Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the…

Leveraging geo-tagging and web filtering for enhanced network security

Quotes from Members

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

Pros

"The technical support is great."
"FortiGate has led to a reduction in our security budget."
"The IPS is good. It protect my network from attackers."
"The most valuable feature is the web filter."
"Generally, every aspect of it being a next-generation firewall provides good value."
"Fortinet FortiGate is considered the best in the European market for security reasons."
"It has very easy management and an amazing ETM configuration."
"The product is easy to use and is stable. The SV1 functionality is a benefit."
"It has been stable so far."
"The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"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."
"In terms of the comprehensiveness of the security features, it does a great job of laying out what it does. It's fairly easy to edit and research. Some of the features were turned on by our IT company and I was able to easily find other features on my own by searching for videos on the internet. I've been able to block certain websites, and content filter, as well as manage some of our bandwidth because we live stream on Sunday. I'm able to dedicate bandwidth for the encoder that goes to the internet. It always has enough bandwidth, no matter how many people are on the network. That's really helpful."
"The firewall appliance itself is the most valuable feature."
"The reporting needs to be improved. It is hard to get a domain."
"The tool shows what has been blocked externally. It's very good because once installed and correctly set up, it allows you to work from home as if you are in the office, without any errors or issues. It's very simple to use, click to connect or disconnect."
"The product is easy to use."
"Compared to other solutions, accounting and live monitoring of firewall status are very good features in KerioControl."
"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."
 

Cons

"There are some cloud-based features that could be much more flexible than they currently are."
"From my experience, I see that the datasheets of the Fortinet FortiGate portfolio need to be more accurate because correct sizing is essential."
"Fortinet FortiGate is not very easy to use. The navigation could be improved to make it easier to use."
"Some of the web policy reports could be improved."
"Fortinet FortiGate could be improved in terms of user friendliness at the policy level and assigning URL based and keyword based features."
"In an incident, after a restart, Fortinet FortiGate did not connect to FortiGuard servers. Due to that reason, on the customer end, all websites got blocked."
"Tunnel flapping was one of the major things I had seen wherein your internet link remains but your VPN tunnel is down. However, since I got a fix from the TAC team, I have not noticed it, but the customer complained a few times that they couldn't access the internet because of this problem."
"One area for improvement involves FortiAnalyzer, specifically regarding the SOC part and log interpretation. Sometimes interpretation is very difficult."
"Licensing is not cheap."
"Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the hotspot get all the functions, and the security does not work."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"The solution should offer more dashboards."
"I find it a bit costly to pay for the products that I am not using. They need to change their model in such a way that you don't have to pay for the products that you are not using. Its local support and scalability are also not good. I am looking forward to a more scalable product that will be able to grow with time and technology."
"When we did our last update, we had some trouble with the initial syncing process to get our messaging to go through. But we were also moving a store and a lot was changing during that process. I don't think it was on Kerio's end. It just coincided with the update. Once we got our third-party IT guy involved it was resolved very quickly."
"After the takeover by GFI, one of the things that Kerio built was MyKerio environment. This has not been very reliable because I get many messages that MyKerio is not functioning. For some reason, there are things that they changed and it is not very reliable at this moment, instead I have to connect to the firewall to see what is happening."
"They don't provide content filtering when it comes to search engine results. We had an incident on the network where a blocked site was showing up in search results. We are in a school environment, so we have blocked a site with some of the explicit content so that kids wouldn't see it. When one of them did a search, the results came on the search engine part. When you try to drill down to the website, it blocks, but when you search by image, it brings up all the images. That's one of the reasons why we are looking at Juniper."
"There isn't a lot to be improved. It works well as it is, but they can maybe improve the reporting side."
"They should improve the remote connectivity feature for users."
"Kerio Control could improve content filtering."
 

Pricing and Cost Advice

"For our organization, the licensing costs are approximately $7,000 per year."
"Our licensing costs are on a yearly basis."
"Its price is normal. If I compare it with other vendors, such as Palo Alto, it's normal. Palo Alto is expensive."
"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."
"The cost of Fortinet FortiGate is competitive and not expensive compared to other enterprise- grade solutions. On average, the license cost per year is around seventy percent of the firewall's purchase price."
"I think the price of Fortinet FortiGate is very reasonable."
"We pay for the solution annually."
"The license is too expensive to renew. The license renewal process is also complex."
"We got a much cheaper price than that provided by Fortinet right now."
"On a scale from one to ten, with one being low and ten being high price, I would rate the price of Hillstone T-Series at three. There are no additional costs other than renewal costs."
"The price of Kerio Control could be better, it is a bit overpriced compared to other solutions."
"Our clients see ROI with Kerio Control, as they are saving bandwidth costs."
"There is a yearly upkeep fee."
"On the low-end device that I use, it has unlimited IP addresses. So, they have a subscription model where, on the higher models, you pay X dollars for 10 IP addresses. Then, if you want any more, you have to pay more on the model. On the low-end model, it has unlimited IP addresses, because if you have too many users, the thing will just slow you down and stop working. At some point, you need to say, "Okay, I've grown to a point where performance is impacted. I need to get some bigger hardware." If I get to that stage, I will possibly look at using one of the virtual appliances and putting it on some bigger hardware."
"Pricing is good, but the licensing took a lot of time."
"The price is inexpensive."
"GFI has made a stupid decision regarding small office licensing. For offices where there are only three to five employees and had five years towards a five user product, they now force these customers to a 10-year user license. I really don't understand it. It's a stupid decision for the small offices who want a good solution for security because they'll probably decide to go to another product. Why should they buy something that they don't use?"
"I think it is a bit on the pricey side, but it's okay. I've got 50 licenses which I think is $250 a year or something like that."
