Unified security has protected diverse environments and supports consistent policies everywhere
I would say 8 out of 10 regarding the stability of Fortinet FortiGate. It requires a lot of bug fixing and what I understand, Fortinet is fast enough to provide bug fixes and patches, but usually I suggest Fortinet should do thorough testing of their releases and software releases and once probably they can reduce the frequency of new releases but make it stable. That's what my recommendation is. As far as the core objective of Fortinet FortiGate is concerned, I think they are meeting the targets but I guess for rolling out new features and new updates, they are doing a bit of hurry just to cope with the market dynamics. But possibly, I understand that they are compromising on the quality of the software and stability. So over there they have to improve. Rest of the aspects, I guess they are doing pretty good. We are happy. Regarding my experience with Fortinet FortiGate in comparison to maybe some other vendors such as CyberArk, Fortinet is in the top three and they give a lot of competition to their nearest peers in the market. But I guess Fortinet is really struggling in software-defined LAN, Wi-Fi, and FortiSwitches space. So they have to make their products more affordable in Forti-switching and Forti-WiFi space. They are not able to compete effectively with the nearest competitor HP Enterprise and HP Aruba.

Has offered reliable threat protection and detailed network insights but could expand features beyond existing capabilities
The best features of Trellix Intrusion Prevention System include advanced ATP (Advanced Threat Protection), which uses signatures, behavior analysis, and machine learning to stop zero-day exploits and malware advanced persistent threats (APTs). They track and collect data from APTs, which allows them to track malicious files entering the environment. The system offers inline prevention and real-time automatic blocking of malicious packets before they reach the network. It integrates with the Trellix ecosystem and provides application visibility and control. The solution provides deep insight into network traffic, applications, and protocols for better information. All packets coming through the application are analyzed and reported. They share intelligence updates regularly to protect from different malicious files and sector-specific threats. It supports both on-premise and cloud environments.

Quotes from Members

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

Pros

"Fortigate can mitigate all attacks, it can handle a lot, it has a good set of UTM features, a good bandwidth shaping mechanism, and other features."
"There is a tool called FSSO, which is a single sign-on user ID agent that works perfectly."
"You don't need to reinvent the wheel, as FortiGate is the best solution."
"SSL VPN, Site to Site VPN, UTM features and web override are nice features."
"FortiGate Next Generation Firewall has a stateless balance proposition"
"It has been very stable and reliable."
"The ECC management and the GUI that offers single interface management are the most valuable features of Fortinet FortiGate."
"The performance is good."
"The most valuable features in Trellix for me are the automated signature updates. It is a great and convenient feature."
"The best feature of the Trellix Intrusion Prevention System is the rules that Trellix provides, I think that's the best value from IPS."
"McAfee NSP is much more stable than Cisco."
"The most valuable features are the customization of the signature and the unlimited amount of custom signatures in IPS."
"The most valuable features of the solution stem from the fact that it is a good product for dealing with DDoS attacks and for the inspection of network traffic."
"We use a lot of the functions this solution provides such as the firewall and the ability to check aliases, and we can monitor and show the traffic that's moving in and out."
"There's a good dashboard you can drill down into. It helps you easily locate intrusions and the source of attacks."
"It improved my security by stopping an attack to the signature base, or the behavior base."
 

Cons

"To stay ahead of the competition Fortinet FortiGate IPS needs to think about how to adjust pricing."
"In the next release, I would like to see the interface simplified to be more user-friendly."
"It could use more templates for third-party site-to-site VPN setups other than FortiGate and Cisco."
"They could improve performance with all the UTM features working. Sometimes, we have seen that when you enable the antivirus sensor, customers report slow web browsing."
"The search tool needs improvement."
"The reporting was limited."
"The issue with Fortinet FortiGate is the many security CVEs around; I have read there are probably multiple critical CVEs above 9.0 in Fortinet FortiGate products."
"There are some complex administration tasks in their administration portal. That needs to be improved."
"The pricing could be improved."
"I haven't seen threat intelligence and machine learning for predictive threat analysis in the Trellix Intrusion Prevention System yet."
"Some of the documentation is not as straightforward as it could be. It's much too general - especially in areas related to updates."
"The solution could improve some aspects of detection."
"The management console needs to be less complex and easier to navigate."
"Trellix Intrusion Prevention System does not provide virtual patching."
"The solution needs to improve the graphical interface. And they had a limitation in some of the sensor modems as well."
"The area of concern where the tool needs improvement is how the product prompts users at a network level that helps prevent any wireless network attacks through alerts and notifications."
 

Pricing and Cost Advice

"It's a year based license."
"It is an inexpensive solution."
"The price of Fortinet FortiGate could improve, it is expensive."
"The price is okay, so far so good."
"The pricing of the solution is very competitive."
"The beauty is the price performance ratio is great with FortiGate. It provides all the features we needed and the price is comparable with others' firewalls. The price is quite competitive with the firewalls with similar features."
"We have the full version of Fortinet FortiGate and we are on a three-year contract with a commitment of five years."
"In the Asian economy in which we operate, FortiGate is expensive."
"I rate the product’s pricing an eight out of ten."
"The tool is competitively priced."

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…
