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.

Unified policies streamline network management but complex licensing requires attention
Cisco Secure Firewall has some growth opportunities in terms of visibility and control capabilities regarding managing encrypted traffic. It has the ability to analyze encrypted traffic, and there is potential for more integration with APIs and AI to enhance these capabilities. Cisco Secure Firewall needs improvement in deployment time and the capability to access the CLI during support calls. I often encounter issues when technical support uses a CLI that is not familiar to me while troubleshooting through the GUI. My ongoing complaint for the last six years has been the lack of CLI functionality, which hinders my ability to work on the firewall, alongside concerns regarding deployment time. For the next release, they should look at the features offered by competitors such as Fortinet, including the ability to perform packet capture directly from the interface. If they enhanced their troubleshooting efficiency related to packet capture for each specific rule, it would simplify the process significantly.

A robust appliance that is reasonably priced and straightforward to set up
Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

Quotes from Members

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

Pros

"The most important features with FortiGate are the web filter and application controls. We can control our internet usage and use the web filter for application purposes."
"I like that they have given me a solution at a fair price."
"The most important features of Fortinet FortiGate are the Intrusion Prevention System (IPS) and firewall control applications."
"The most useful functionality of Fortinet FortiGate is the user interface, multiple engines, and their cloud with the latest integrations. Additionally, the Security Fabric tool is very good."
"Fortinet FortiGate provides excellent security against ransomware attacks."
"Its user interface is good, and it is always working fine."
"It is easy to manage, and it doesn't need much knowledge from the team. It is a stable device, and there are many features that are included out of the box."
"The pricing is excellent. It's much less expensive than Cisco."
"The most valuable features for my client are the ASDM and monitoring."
"The technical team is always available when we have problems."
"There is a good relationship between real throughput, meaning the root performance, and the data sheet performance."
"When it comes to the integration among Cisco tools, we find it easy. It's a very practical integration with other components as well."
"The Firepower IPS, based on Snort technology, has an amazing detection engine and historical analysis capability of files that eases threat investigations a lot."
"The initial setup is easy."
"Their performance is most valuable."
"The important features are IPS intrusion prevention, anti-malware, and anti-spam."
"The solution can scale well."
"This is a capable appliance and the standard features work well for us."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
 

Cons

"I would prefer to have more detailed logs within the FortiGate products themselves rather than relying on a separate tool."
"Fortinet technical support is lacking, as OEM support is slightly better. Improvement in their technical support could include response time as well as having more technically sound people in tech support."
"Fortinet currently has many products bundled with FortiGate including the basic firewall and load balancer, and I think that that they need to have separate product portfolios for each of these specialized services."
"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."
"Improvements for Fortinet FortiGate could be made by making it easier to implement on networks and simpler to add users and accounts that utilize this solution. That's basically the only challenge that I see."
"In most cases, the IPS engine uses too many resources, which makes Fortinet FortiGate devices unstable."
"Performance on the box and technical support are areas where Fortinet FortiGate can be improved."
"The UI could be improved."
"It is expensive."
"There may have been one or two incidences of malicious threats."
"Tech support could not answer all of our questions. I had to do research on the web to solve my issues."
"If you need to reschedule a call with the support team when you face a new issue with the product, then it may get a bit of a problem to get a hold of someone from the support team of Cisco."
"The solution is overcomplicated in some senses. Simplifying it would be an improvement."
"One issue with Firepower Management Center is deployment time. It takes seven to 10 minutes and that's a long time for deployment. In that amount of time, management or someone else can ask me to change something or to provide permissions, but during that time, doing so is not possible. It's a drawback with Cisco. Other vendors, like Palo Alto or Fortinet do not have this deployment time issue."
"The virtual firewalls don't work very well with Cisco AnyConnect."
"There are some limitations with SSL. Regarding the security assessment for the ISO 27000 standard, there are certain features that Cisco needs to scale up. Not all products support it, so you need to be slightly careful, especially on the site track."
"Sometimes it reboots when you least expect it, and that's the main issue."
"The product has some scalability and data management issues where improvements are required."
"Although manageable, the user interface is a little bit slow and could be improved."
 

Pricing and Cost Advice

"It is an inexpensive solution."
"Fortinet bundles FortiGate with other products and because of this, the price is a little expensive to some SMB enterprises."
"It is a good product from a price perspective versus functionality."
"Licensing is usually on a three-year period."
"​We saved a bundle by not needing all the past appliances from an NGFW.​"
"Work through partners for the best pricing."
"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."
"We just pay a flat monthly fee to the vendor for the support."
"It is a great solution for medium or big enterprises, not so much for small businesses, mainly due to the financial costs."
"Cisco Firepower is a great solution, but it is expensive compared to others that can provide similar benefits for much less."
"They have a lot of different models but most of them are really expensive."
"Cisco is always expensive, but you get what you pay for. It is expensive for a reason. It is a good solution, and good solutions cost money."
"Pricing is why we had to go for a UTM. For us to achieve what we needed, if we had gone with the ASA, the cost would have been high compared to getting one box (UTM)."
"It's a brilliant firewall, and the fact that it comes with a perpetual license really does go far in terms of helping the organization in not having to deal with those costs on an annual basis. That is a pain point when it comes to services like the ones we have on Fortigate. That's where we really give Cisco firewalls the thumbs up."
"The licensing is not good, it's confusing. I'm an engineer so I don't care about the actual price that much but the licensing part is confusing."
"ASA pricing seems high compared to other firewalls, such as the Sophos XG models."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."

Cisco ASA vs. Palo Alto Networks
Cisco ASA vs. Palo Alto: Management Goodies You often have comparisons of both firewalls concerning security components. Of course, a firewall must block attacks, scan for viruses, build VPNs, etc. However, in this post I am discussing the advantages and disadvantages from both vendors concerning…
