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

"It is simple to manage, and there are a lot of functionalities in the same box."

"I like several features that this product has, such as antivirus and internet navigation inspection. It is also simple to use."

"Run Script is the best tool to use in Fortinet FortiGate with multiple environments."

"This solution has solid UTM features combined with a nice GUI."

"The dynamic segmentation feature in Fortinet FortiGate is pretty good."

"The tool is a nice product and easy to handle. The software's user interface is also good. You can easily implement remote access in the solution."

"It's a flexible solution and is well-known in the community."

"You do not have to do everything through a command line which makes it a lot easier to apply rules."

"It's a flexible solution."

"It integrates with various Cisco security portfolios and products, and there is an easy and seamless integration for building a complete security framework for our customers."

"IPSec Tunnel and AnyConnect (of course), the context awareness was a good feature, but clumsy at the beginning. I think it's better now."

"The greatest benefit that this has provided to our organization is that we've been able to adjust the time that it takes to implement firewall changes. It's gone from a week to less than half a day to implement a change, which means that our DevOps team can be much more agile, and there is much less overhead on the firewall team."

More Cisco Secure Firewall pros

"The most valuable feature is availability."

"Prevention of evasive threats is one of the best tools I've encountered."

"The most valuable feature of Palo Alto Networks K2-Series is the configuration, it is very clear."

"The customer service and support are really good."

"The most valuable feature of Palo Alto Networks K2-Series is its management abilities. Additionally, the updates are very good."

"Simple integrations with the domain controllers and other inventories"

Cons

"Due to its higher cost, Fortinet FortiGate can lead to increased operational expenses."

"One drawback of Fortinet FortiGate is that they provide two types of models: one with a hard disk and another without. The model without a hard disk has very low ROM where you can store very few logs, after which you need to upload it to the cloud or purchase a firewall with SSD."

"Fortinet FortiGate could be improved in terms of user friendliness at the policy level and assigning URL based and keyword based features."

"Its reporting can be improved. Sometimes, I don't get proper reports."

"They need to improve their technical support."

"The license renewal process, annual renewal price, and the web application firewall features should be improved."

"It should have a better pricing plan. It is too expensive. It should also have a more granular view of the attack. I don't have FortiAnalyzer, and it is difficult for me to have a complete view when there is an attack on my server."

"I feel that the reporting needs to be improved."

More Fortinet FortiGate cons

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

"We have encountered problems when implementing new signatures and new versions on our firewall. Sometimes, there is a short outage of our services, and we have not been able to understand what's going on. This is an area for improvement, and it would be good to have a way to monitor and understand why there is an outage."

"I have worked with the new FTD models and they have more features than the ASA line."

"The security features in the URL category need more improvement."

"This solution could be more granular and user-friendly."

"Most of the features don't work well, and some features are missing as well."

"Technical support is unsatisfactory for me. There might be restructuring within Cisco India or with the partner's capability."

"The most valuable features of the product are the VPN and the NextGen firewall features such as application control, URL filtering, etc."

More Cisco Secure Firewall cons

"Threat prevention could use improvement."

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

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

"Palo Alto has many other products. It would be nice for these products to be centralized under one tool"

"The technical support, and how they provide it to the client, needs to be improved."

"When it comes to renewing the solution, they tend to try to jack up the pricing."

"Its networking features could be better."

"The ease of management and configuration should be improved."

Pricing and Cost Advice

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

"The cost of Fortinet FortiGate is competitive and not expensive compared to other enterprise- grade solutions. On average, the license cost per year is around seventy percent of the firewall's purchase price."

"It is more expensive than Sophos. Fortinet is overall more expensive than Sophos. The small range of Fortinet, such as 60F and 80F, is more expensive than the small range of Sophos. Sophos is cheaper. In addition, if you jump from 80F Series to 100F Series, the price doubles."

"I find it quite reasonable."

"Its pricing is competitive with other solutions."

"Cost-wise, there is not much difference from Sophos, but feature-wise, we get more features."

"Fortinet FortiGate as a less expensive solution than Palo Alto."

"The price of Fortinet FortiGate is better than Cisco, Check Point, and Palo Alto. In terms of pricing, it's probably a better-priced firewall solution overall."

More Fortinet FortiGate pricing and cost advice

"Cisco smart licensing is a hassle for a disconnected environment."

"I know that licensing for some of the advanced solutions, like Intrusion Prevention and Secure Malware Analytics, are nominal costs."

"It's very competitive with other products."

"Its price is in the middle range. Both Firepower and FortiGate are not cheap. Palo Alto and Check Point are the cheapest ones. I don't remember any costs in addition to the standard licensing fees."

"The pricing is fair."

"The prices of Cisco Secure Firewall are competitive, especially for us as Cisco partners. We purchase the products directly from Cisco as a gold partner, which allows us to obtain better pricing than we would get from normal distributors or the local market."

"Cisco is not really cheap, but there is great technology behind it."

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

More Cisco Secure Firewall pricing and cost advice

"The price of this solution is too high."

"We are on an annual license to use Palo Alto Networks K2-Series."

"It is an expensive solution."

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

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

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

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