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.

Offers good features like URL filtering, IPS, and IDS to users

We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

Quotes from Members

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

Pros

"The Fortinet FortiGate local partners were good. I did not have direct contact with Fortinet support."

"The ease of use and the user-friendly interface are the beauty of this firewall."

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

"The security for endpoints is the most valuable; it is very secure for our workers and allows us to secure a transaction and enable security for a specific segment in the workflow."

"It controls the traffic in the organization and the navigation of the Internet, blocks some sites, permits limited access to our information through the web, and lets us detect any attack of viruses or malware at the first point of contact."

"Fortinet FortiGate has it all."

"The security features that they have are quite good. On top of that, their licensing model is quite nice where they don't charge you anything for the SD-WAN functionality for the firewall."

"I like the security that Fortigate offers; it has great URL filtering with a next-generation firewall that can do internet routing, plus give us advanced layer seven application control."

More Fortinet FortiGate pros

"Cisco’s AnyConnect SSL VPN is by far the best client VPN technology I’ve ever had to deploy and manage."

"Technical support is good; they were both fast and reliable and quick in making decisions, and when we faced specific issues, tech support was efficient and provided an immediate solution."

"You can also put everything into a nice, neat, little package, as far as configuration goes. I was formerly a command-line guy with the ASA, and I was a little nervous about dealing with a GUI interface versus a command line, but after I did my first deployment, I got a lot more comfortable with doing it GUI based."

"The most valuable feature of the Firepower solution is FireSIGHT, which can be easily managed and is user-friendly."

"This solution is easy to use if you know how to set it up."

"This product is pretty stable."

"The feature I have found most valuable is the IPS advanced threat detection for removing ransomware and malware."

"Cisco ASAs are great network firewalls and they can work for years after being configured."

More Cisco Secure Firewall pros

"Five out of five ROI."

"Very reliable solution with good scalability and straightforward implementation."

"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."

"I am impressed with the application filtering feature."

"The most valuable feature of the solution is the ransomware protection that the tool offers."

"If an organization is not looking for a web proxy, it's a very, very good product."

"This solution has two main features that we find very valuable; a threat-intelligence option, and a web/application filtering option."

"The initial setup was straightforward. It only took a few hours to deploy."

More Hillstone E-Series pros

Cons

"One area for improvement is the IPS engine."

"Fortinet FortiGate can improve by integrating the web application firewall and the DDoS protection part of the solution. Having a WAF feature, web application firewall, and proxy together would be a good benefit."

"Its performance can be better. We have had performance issues in the past, but we sometimes tend to find that it is more related to what we do in our network than anything else."

"In the past six to seven years with the Fortinet FortiGate, we've had two major downtimes, both caused by firmware upgrades."

"FortiManager has not been my favorite. I don't use it and cannot say I really care for FortiManager for managing the firewalls."

"The room for improvement is about the global delivery time period. Usually I need to wait for almost one month to deliver it overseas."

"Some features of Fortinet FortiGate are actually fee enabled that are inconvenient for deploying in production. Other issues relate to isolation with Cisco products and your server."

"At first glance, the interface for the device is very confusing."

More Fortinet FortiGate cons

"The Firepower FTD code is missing some old ASA firewalls codes."

"I would like to see more configurable feature parity with Cisco ASA, which is the legacy product that Cisco is moving away from. When configuring remote access VPN, not all of the options are there. You have to download another tool, which means that the configuration takes a little bit longer with Cisco Secure Firewall. Though it's getting there, there are still some features lagging behind."

"The operation of the ASA is good but the problem is that whenever you require an upgrade, there are multiple pieces of software that you have to upgrade."

"Cisco should improve its user interface design. There is a deep learning curve to the product if you are a newcomer."

"The cost is very high. Most organizations cannot afford it."

"There were a few problems with the interaction between the ASDM client and ASA device."

"The installation and integration of Cisco ASA with Firepower can be improved. The management with Fortigate is easier than Cisco ASA on Firepower."

"To improve Cisco Secure Firewall product, we have a TAC case open for that, but I would prioritize responsiveness for sure, as UX/UI is always something to work on."

More Cisco Secure Firewall cons

"Having frequent live webinars on a monthly basis would really help."

"SSL VPN license cost is not cheap."

"The tool only had some memory-related problems."

"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."

"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."

"The current usage reporting is very basic. I would like to be able to access more granular data."

"The tool needs to improve its price."

"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."

More Hillstone E-Series cons

Pricing and Cost Advice

"No comment."

"The pricing is better compared to other solutions like Check Point, Arista, or Cisco."

"If we have an older version, the support costs get quite high."

"Fortinet FortiGate allows you to purchase licenses for hardware and software."

"The pricing is fair."

"The licensing costs are very low."

"It was worth the money overall. It's good value."

"We just pay a flat monthly fee to the vendor for the support."

More Fortinet FortiGate pricing and cost advice

"Cisco is expensive, but you do get benefits for the price."

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

"The cost of keeping the licensing up on the ASA is very expensive. It has a lot of positives, but the cost of going with it is really starting to be a major negative right now."

"The price of this solution is not good or bad."

"The pricing seems fair. It is above average."

"You get what you pay for. It's always priced based on what you get and what it can handle. It's acceptable."

"I bought a license for three years and it was really affordable."

"Based on the services that you will get, especially the AMP license, the price is very reasonable."

More Cisco Secure Firewall pricing and cost advice

"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."

"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."

"Hillstone's pricing is economical and neither very high nor very low."

"The tool's pricing is reasonable. It depends on the model. The product's pricing is around 600 USD. You need to buy a software license to activate the features. You need to pay around 150 USD for that."
