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.

Quotes from Members

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

Pros

"This solution has solid UTM features combined with a nice GUI."

"The impact of SD-WAN on the network performance has been significant."

"Security, SD-WAN, and Streetscape are valuable features."

"I think that the UTM features are the most value, as it truly protects my infrastructure."

"The main benefit is the grouping of our security monitoring."

"We were looking for the VPN feature and controlling the inflow and outflow of all the traffic within the site and across the sites. We are also using it for the VPN and VLANs."

"Fortigate's most valuable feature is that it doesn't need a push policy when writing rules."

"The best features of Fortinet FortiGate are that it does the job effectively and protects our environment."

More Fortinet FortiGate pros

"The solution can scale well."

"This is a capable appliance and the standard features work well for us."

"The Zyxel Unified Security Gateway solution is stable and does its job effectively."

"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."

Cons

"FortiGate Next Generation Firewall could be made a little less expensive."

"Fortinet FortiGate could improve by having a frequent ask questions(FAQ) area for people to receive quick answers to popular questions. Additionally, it would be beneficial to have an SMS notification feature. For example, if you cannot access your email you could receive an SMS message."

"I would like to have logs, monitoring, and reporting for a month without extra fees."

"At the moment, if you don't integrate any third-party solution with a simple Fortinet FortiGate box, the box would not function as expected for superb protection."

"The vendors offer models with different levels of productivity of the product to its users, which is not possible in FortiGate Next Generation Firewall (NGFW). It lacks integration options."

"Scalability is one of the disadvantages. When it comes to scalability, you have to actually change the box. If you want to upgrade it, you need to actually change the existing box and probably you take the system off to other sites."

"The only issue that I have is with FortiNAC. The firewall is fine, but the FortiNAC interface is a little bit too jumbled or too complicated, not as straightforward as it is on the Fortinet FortiGate firewall and FortiAnalyzer."

"The platform's compatibility with Wi-Fi equipment needs improvement."

More Fortinet FortiGate cons

"The product has some scalability and data management issues where improvements are required."

"Sometimes it reboots when you least expect it, and that's the main issue."

"Although manageable, the user interface is a little bit slow and could be improved."

Pricing and Cost Advice

"We are currently evaluating a Palo Alto solution, and the pricing could be a reason for going for Palo Alto."

"Easy to understand licensing requirements."

"The price of FortiGate is good."

"The tool is a bit pricey for small businesses, but it is still bearable in terms of cost."

"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."

"The price is really low. It's cheap in comparison to the cost of Cisco or CheckPoint, for example."

"Licensing is usually on a three-year period."

"Pricing is lower than Cisco."

More Fortinet FortiGate pricing and cost advice

"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."

Sophos UTM vs. Fortinet FortiGate

I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
