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

Phil Shiflett

Senior Manager, Network Engineering at TTi Power Equipment

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.

One of the best tools for the prevention of evasive threats

Krishnakumar M

enterprise architect at a tech services company with 1-10 employees

There is a feature called granular application controls, which I liked. Instead of relying on ports and IP addresses, they use AMP ID. This kind of solution is very good. Another valuable feature is the prevention of evasive threats, which is one of the best tools I've encountered. SSL decryption and app ID-based SSL decryption are also impressive, along with the integration with user ID. Identity-based policies ensuring only authorized users can access specific resources are excellent features. Normally, there is something called SIM or SCIM in IDA IDM, but this feature is provided on the box, which is exemplary.

Quotes from Members

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

Pros

"The solution is scalable."

"Application control and the web filter are the best features of Fortinet FortiGate."

"The solution is stable."

"Fortinet FortiGate is a stable solution."

"The VPN is the most valuable feature."

"The most valuable features of Fortinet FortiGate are the APIs. They are the most widely known."

"The FortiGate controls the user's activities and maximizes my bandwidth use overall."

"It's very fast and easy to configure."

"Its VPN and ASN features are very stable."

"The configuration was kind of straightforward from the command line and also from the ASDM. It was very easy to manage by using their software in Java."

"I love the ASDM (Adaptive Security Device Manager) which is the management suite. It's a GUI and you're able to see everything at a glance without using the command line. There are those who love the CLI, but with ASDM it is easier to see where everything is going and where the problems are."

"Cisco Secure Firewall has improved our customers' security posture because it offers Next-Gen features, granularity, and reporting on the back of it. You can see the amount of users accessing Office 365, for example, and whether they're having a good or bad experience. You can see the threats that are coming into your network. You can see anyone who is compromised from within your network."

"Cisco Secure Firewall is easy to configure, and you can do it all in one pane of glass."

"The VPN feature is the most valuable to us because it accomplishes the task well. We're able to do everything we need to do."

"It is a very user-friendly product."

"This solution has good security, and it's a good product. You can trust Cisco, and there's support as well, which is really good."

More Cisco Secure Firewall pros

"The company is inventive and always adds a lot of great features."

"The solution offers effective security features such as HIDS (Host-based Intrusion Detection System) in global products."

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

"The most valuable feature of Palo Alto Networks K2-Series is the performance which is above their competitors. The throughput they have delivered is good. When we used other solutions they failed the deployment when we were using different rules. They have a theory perform performance light and performance degradation. However, Palo Alto Networks K2-Series never fails in that scenario."

"The scalability of the product is quite high."

"This firewall is very good for our customers because they don't have to write their own rules for adding an application."

"The customer service and support are really good."

"It's easy to configure."

More Palo Alto Networks K2-Series pros

Cons

"Fortinet FortiGate needs to improve the protection, it did not prevent us from being attacked. Additionally, Fortinet FortiGate could provide more features for WAF devices. I should not have to purchase two solutions, it would be a benefit to combine these features into one solution."

"The UI could be improved."

"We would like to have the ability to disable some of the security functionalities."

"One area for improvement is the performance on bandwidth demands for smaller devices, as well as better web filtering."

"I would rate Fortinet support a six out of ten. The immediate response is not that good, particularly when raising a critical or P1 ticket; they lag in the immediate response."

"I would prefer to have more detailed logs within the FortiGate products themselves rather than relying on a separate tool."

"When we cluster the two Fortinet FortiGate boxes together we have some issues."

"In the future, I would like to see improvements made to cloud-based management."

More Fortinet FortiGate cons

"10Gb interfaces should be available on more models."

"The change-deployment time can always be improved. Even at 50 seconds, it's longer than some of its competitors. I would challenge Cisco to continue to improve in that area."

"One area that could be improved is its logging functionality. Your logs are usually displayed on the screen, but if you want to go back one or two days, then you need another solution in place because those logs are overwritten within minutes."

"More intuitive support for SIP services are needed. This took a long time to configure properly for the user."

"One of the challenges we've had with the Cisco ASA is the lack of a strong controller or central management console that is dependable and reliable all the time."

"I don't have any specific improvements to recommend. However, when you compare the throughput of a Cisco firewall to the competitors, especially Fortinet, what you find is that Cisco has lagged a little bit behind in terms of firewall throughput, especially for the price that you pay for that throughput."

"An area for improvement is the graphical user interface. That is something that is coming up now. They could make the product more user-friendly. A better GUI is something that would make life much easier."

"It is a good firewall, though not NextGen."

More Cisco Secure Firewall cons

"I cannot think of anything specific to improve at the moment."

"I would like to see the threat intelligence capability integrated with other vendors such as Cisco and Forcepoint."

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

"There are a lot of bugs in this solution."

"The scalability for on-premises version is limited as it depends on the model."

"The tool needs to improve integration with more products from other vendors. I would like the product to add threat intelligence features as well."

"It is recommended that the Palo Alto Networks K2-Series be implemented step by step for the Panorama. Sometimes we can't overwrite the configurations because it fails."

"In the past, we've had trouble with Palo Alto's application filtering not getting it right. I would not be recommending layer 7 application filtering yet."

More Palo Alto Networks K2-Series cons

Pricing and Cost Advice

"The price of Fortinet FortiGate is affordable. Most of our customers are on a three-year license to use the solution. All the features and support are included in the price."

"The pricing of the solution is very competitive."

"This is not a cheap solution but it isn't expensive, either. It's a good solution for the right price."

"They need to be competitive with other solutions."

"Its pricing is competitive with other solutions."

"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."

"Fortinet FortiGate gives you most of the features in one license."

"In terms of the market, it's not a cheap product, but it's cost-effective."

More Fortinet FortiGate pricing and cost advice

"I wish there was an easier way to license the product in closed environments. I have worked in a number of closed environments, then it is a lot of head scratching. I know that we could put servers in these networks and that would help with the licensing. I have never been in a situation where we connected multiple networks, i.e., having an external network as well as an internal network, as those kinds of solutions are not always the best. I think licensing is always a headache for everyone, and I don't know if there is a simple solution."

"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."

"It is extremely expensive compared to its competitors and I would rate it 2 out of 10."

"License capacity needs to be extended and the vendor needs to work on the pricing."

"The product is very expensive."

"Their pricing is very aggressive and good. Even a small company can afford it. I am happy with its pricing. Its licensing is on a yearly basis."

"I like its licensing because you buy the license once, and it is yours. We don't have to go for a subscription. So, I liked how they licensed Cisco ASA. Our clients are also very satisfied with its licensing model."

"Be sure of what features you are going to utilize to add/remove some from new bundles."

More Cisco Secure Firewall pricing and cost advice

"Pricing is a sensitive issue because the cost is high in this market."

"The overall price of Palo Alto Networks K2-Series could be reduced."

"The price of this solution is too high."

"Palo Alto firewalls are very expensive."

"This product is designed for large companies. The price would not be suitable for a small or medium size company."

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

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

"It is an expensive solution."
