Manager, Information Technology Operation/Presales at TechMonarch

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.

Perimeter security has reduced botnet attacks and now needs better interface and logging

The best features Arista Edge Threat Management NG Firewall offers are its ability to push a lot of traffic along with bandwidth management and traffic policy. Bandwidth management and traffic policy help my organization by keeping our internet subscription low. Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks. Immediately after I installed the firewall, it stopped a few botnet attacks.

reviewer9216065

Sr. Cloud Security Architect at a tech services company with 11-50 employees

Has provided strong traffic visibility and efficient policy management for advanced network environments

Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.

Quotes from Members

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

Pros

"The most valuable feature is the FortiManager for centralized management."

"The most useful features in Fortinet FortiGate are the security features, where we can analyze what kind of traffic is inside our network, and we also utilize ZTNA for limiting and managing our network access."

"The most valuable feature of Fortinet FortiGate is URL filtering."

"I would recommend using Fortinet FortiGate because of its usability."

"The security fabric is excellent."

"It blocks the vulnerabilities that can negatively impact us."

"The most useful features of Fortinet FortiGate IPS are you can create a virtual firewall within it, most other firewalls do not have this feature. You are able to manage your network and have network segmentation within your firewall. Additionally, you can create virtual switches within the firewall and have policy management, such as firewall and access policy."

"The most valuable features of Fortinet FortiGate are the ease of use and the UI. It has always provided me with what I needed. I have no need for additional costs that other solutions have, such as Sophos."

More Fortinet FortiGate pros

"Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks."

"The product's initial setup phase is easy."

"Phish Blocker is a valuable feature."

"Regarding traffic visibility features and Advanced Threat Prevention aspects, I would assess these functions as awesome; it's unparalleled, not just for K2-Series, but in general for Palo Alto."

"Everything I could possibly want has already been implanted in the new version."

"It's easy to configure."

"Overall, this is a very simple and very effective firewall, and I am satisfied with it."

"I have found the threat profile feature valuable."

"The most valuable features are the virtualization of the firewall and the antivirus."

More Palo Alto Networks K2-Series pros

Cons

"Right now, it's not really scalable, but it's okay for us. However, looking ahead to three years from now, we might have a problem with scalability. We foresee a little risk down the road. The stability is okay for now."

"The pricing could be reduced or include the first year warranty."

"If I had any criticism that I would give FortiGate, it would be that they need to stop changing their logging format. Every time we do a firmware upgrade, it is a massive issue on the SIM. Parsers have to be rebuilt. Even the FortiGate guys came in and said that they don't play well in the sandbox."

"Fortinet FortiGate could improve by adding enhancements to FortiMail, FortiSOAR, and FortiDeceptor."

"There could be more modifications."

"The firmware needs improvement because there are bugs when a new release comes through. Sometimes, the configuration changes, and it's a bit harder to see where the fail is. The first time that you have the firmware, it tends to have some issues, and it's better to wait a bit to update the equipment."

"One of the problems I was having was with user mapping, and it is an issue for which I have escalated tickets with Fortinet support."

"I have used technical support and they could improve."

More Fortinet FortiGate cons

"The documentation is not clear."

"Arista Edge Threat Management NG Firewall can be improved, particularly the user interface, which is not very good, and also the logs, which are not very good."

"The product has a lot to improve in the area of policy implementation."

"Threat prevention could use improvement."

"With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models."

"I'd like to see more data protection on the system."

"It would be really helpful to have dashboards that provide information on IOC blockings such as where and how many. It will also be good to know how many hashing files have been reported. It would also be nice to have easy access to this information. Otherwise, it's a painful, manual task."

"Higher levels of support are excellent but new users may need additional options."

"The graphical user interface is a little complex and difficult to manage. L1 engineers cannot work on the Palo Alto Networks K2-Series because it's too complex, which requires L2 and above level of engineers."

"The URL Filtering module needs to have more categories added to it."

"The password function of the solution could be improved. Additionally, some of the processes take too long to complete."

More Palo Alto Networks K2-Series cons

Pricing and Cost Advice

"Pricing is lower than Cisco."

"It is more affordable than Check Point and Palo Alto. Another thing is that all the features and the OS remain the same irrespective of the size of the device. Pricing-wise, Fortinet typically provides one-year support with the firewall appliance. There is also an option for three years which is how their licensing works."

"The solution could be better priced."

"FortiGate SWG is a cost-effective solution well-suited for organisations of all sizes."

"Some of our customers are using Sophos and SonicWall due to price concerns, as they can't manage the pricing of Fortinet FortiGate."

"Fortinet's pricing is more straightforward than other solutions. If Fortinet doesn't stick out when you're searching for a solution, you are a glutton for punishment. You only need to know two things when purchasing a Fortinet solution: your total bandwidth and bandwidth at the site. You need to estimate the future bandwidth with other solutions if your customer plans to upgrade."

"It's a very full-featured and it's priced well solution."

"I think price-wise, the solution is totally reasonable since it has many products to serve, starting from small homes to massive scale sites."

More Fortinet FortiGate pricing and cost advice

"The tool is quite cheap."

"I consider it an averagely-priced tool."

"This is an expensive solution, although you will get value for the price."

"The price of this solution is too high."

"If you compare K2-Series' quality with its price, I think it is reasonable."

"It would be nice if they lowered their prices for small businesses."

"This solution is expensive compared to other, similar products."

"The price of the solution is expensive."

"Palo Alto Networks K2-Series is an expensive solution, the price could be reduced. They are more expensive than some of their competitors."

"Products by the leader in the field are justifiably a bit more expensive compared to other vendors."
