Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

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.

Application control excels and integration with monitoring system boosts efficiency
I am an integrator working with Palo Alto Networks CN-Series and Panorama. I have been involved with the implementation of Palo Alto Networks CN-Series The stability of Palo Alto Networks CN-Series is excellent. Application control is one of the most valuable features. Its monitoring capability…

Quotes from Members

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

Pros

"I like that you are able to manage FortiGate from the FortiManager to create a more centralized environment."
"Fortinet FortiGate has improved our routing and made us more secure."
"The Fortinet product provides enterprise capabilities in a small footprint at a price point that is more attainable for a small business."
"Security management tool that's easy to integrate and easy to work with. No issues found with its stability and scalability."
"The feature that I find most valuable is its protection of the websites."
"Fortinet FortiGate is a firewall that protects all network data."
"Typically, we use Fortinet FortiGate with edge devices for businesses, we also use them to integrate with a SIEM product and we use it for detailed analytics."
"From the firewall perspective, the rules and policies are very sufficient and easy to use."
"Its Snort 3 IPS has better flexibility as far as being able to write rules. This gives me better granularity."
"The most valuable feature is the access control list (ACL)."
"The fact that it's a full inspection firewall."
"Most of same old ASA 5520 config could be used for the new 5516-X model."
"I have access to the web version of Cisco Talos to see the reputation of IP addresses. I find this very helpful. It provides important information for my company to obtain the reputation of IP addresses. The information in Talos is quite complete."
"The feature that I found most valuable is the overall stability of the product."
"In terms of how the ASAs have affected our security posture as an organization, it's done well."
"My advice for anybody who is implementing Cisco ASA is that it is not very difficult to deploy and not very difficult to understand how to continue adding more rules to it."
"The stability of Palo Alto Networks CN-Series is excellent."
"The app inspection is very helpful for network security."
 

Cons

"The firmware needs improvement because there are bugs when a new release comes through."
"The customization is a little bit difficult."
"I think that the infrastructure for the VPN could be improved. The way that it is bundled also made it difficult to use and sell as it is too expensive."
"The price could be improved."
"Fortinet FortiGate should improve the VPN tokens."
"The customer support is expensive. We have had difficulties with technical support from Fortinet."
"I would like to see a more intuitive dashboard."
"The security features could have been more similar to those in the Palo Alto firewall with major data protections and WildFire, and deeper inspection capabilities, which Fortinet FortiGate lacks."
"Cisco support is okay, but not great. The response time is too long."
"I think the old interface could be improved, as it is not that good."
"The scalability has room for improvement."
"Regarding stability and reliability, I have experienced false negative alerts with the CS models, which indicate that my switch has gone down when in reality, it has not. That is a fix that is needed."
"It just doesn't have any. It's just a box which does firewalling."
"One feature I would like to see, that Firepower doesn't have, is email security. Perhaps in the future, Cisco will integrate Cisco Umbrella with Firepower. I don't see why we should have to pay for two separate products when both could be integrated in one box."
"The solution needs to have better logging features."
"It is hard to collaborate with our filtered environment."
"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."
"I'd like to see more IOPs features."
 

Pricing and Cost Advice

"The solution requires a license annually, it is not a user license, you can have as many users as your want. I must renew the license regularly per device."
"It is cost-effective, and provides a good value for your money. The pricing, and license renewal, is very reasonable for us."
"They are more expensive than others."
"Fortinet FortiGate is expensive."
"The support subscription for the solution is annual. You are paying for support and there are two levels of support, professional and advanced."
"The price of FortiGate is good."
"Fortinet has one or two license types, and the VPN numbers are only limited by the hardware chassis make."
"Cost-wise, there is not much difference from Sophos, but feature-wise, we get more features."
"All our requirements which we need performed by the firewall (e.g. VPN, URL white-listing, or IP based white-listing, etc.) have separate licenses and costs."
"To discuss with Cisco Systems or their partners to gain the optimal price and to not consider, without verifying, the false information that Cisco ASA is very expensive."
"The pricing structure for Cisco Secure Firewall can be challenging to manage."
"Pricing for Cisco is expensive. There are additional costs for the licensing part, support, and even the hardware part. The device cost is very high. I would be very happy with an improvement on the price."
"It definitely competes with the other vendors in the market."
"The pricing and licensing structure of the firewall is fair and reasonable."
"Licensing with Cisco Secure Firewall isn't too difficult. However, pricing seems high. We had been using a Meraki solution, and Cisco Secure Firewall seems more expensive than Meraki, even though Meraki is also cloud-based."
"The licensing scheme is completely confusing, and they need to streamline it. They have classic licensing and a new type of licensing now. Also, the licensing for the actual firewall is separate from the one for TAC support."

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…
