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 SD-WAN feature of Fortinet FortiGate has been most impactful in maintaining our network's integrity."

"I think that the UTM features are the most value, as it truly protects my infrastructure."

"Fortigate is very scalable to serve our customers' needs. We have scaled already from fifty to more than a hundred instances of Fortinet FortiGate. Around 20 staff are required for deployment and maintenance, mostly engineers."

"FortiGate has a strong security topic which allows all of the Fortinet devices to communicate and share information which makes their security more powerful."

"We use a southern institution that's audited for IT security and the reporting that automatically comes off the unit makes it much easier to meet compliance standards and makes it easier as far as the amount of time that has to be spent to compile that information. If you get your reporting set up correctly when you initially set it up, you just select the one you want and hit print. The auditing trail on it is the best feature."

"Fortinet FortiGate is stable. It's used across all the countries, this is the way most multinationals run their system."

"FortiGate is more feature-rich and has a broader range of hardware. T"

"FortiGate is on the cheaper end, and it offers good value."

"We feel that we can trust the security, and our assets and business are well protected. We need to have trust in it, but we also see that it works. We have a security company that has tested that it works."

"The most valuable feature for the customers is that they can control what communication is allowed and what is not allowed. That is, they can allow or deny client traffic."

"Signature-based detection; user-defined signatures with regular expressions; integrated URL and content filtering; custom URL categories filtering."

"It allowed us to consolidating multiple security devices into a single appliance."

"If configured, Firepower provides us with application visibility and control."

"We found the initial setup to be easy."

"Its in-depth monitoring and analysis help us to make better decisions and policies."

"Cybersecurity resilience has been paramount. Because there is a threat of losing everything if ransomware or another sort of attack were to happen, the cybersecurity resilience has been top-notch."

More Cisco Secure Firewall pros

"I have found that Palo Alto Networks K2-Series has the best security. They are more user-friendly, older firewalls used to have to be configured using the command-line interface, but in this solution, it can be done in the GUI."

"Palo Alto has a unique solution for DNS security, which is very good."

"Overall, this is a very simple and very effective firewall, and I am satisfied with it."

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

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

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

"Mainly, it is very easy to understand, and the logs are very good."

More Palo Alto Networks K2-Series pros

Cons

"They should improve high CPU and memory usage that occurs."

"A sandbox would be good in order to be able to inspect the emails containing spam and be able to validate the emails that contain malware, prior to delivering to the customer."

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

"Fortinet FortiGate is not a scalable solution, as they give you a number and each box comes with concurrent connections; if you need to expand, you have to change the box."

"They sometimes hide some features and if you want to enable them, you have to go in the CLI, enable the feature and configure it through the CLI. Customers, typically, like everything to be done by the GUI."

"Compared to some other products, the DLP is not at par for the moment."

"It needs more available central management."

"FortiGate is really good. We have been using it for quite some time. Initially, when we started off, we had around 70 plus devices of FortiGate, but then Check Point and Palo Alto took over the place. From the product perspective, there are no issues, but from the account perspective, we have had issues. Fortinet's presence in our company is very less. I don't see any Fortinet account managers talking to us, and that presence has diluted in the last two and a half or three years. We have close to 1,500 firewalls. Out of these, 60% of firewalls are from Palo Alto, and a few firewalls are from Check Point. FortiGate firewalls are very less now. It is not because of the product; it is because of the relationship. I don't think they had a good relationship with us, and there was some kind of disconnect for a very long time. The relationship between their accounts team and my leadership team seems to be the reason for phasing out FortiGate."

More Fortinet FortiGate cons

"Cisco ASA is not a next-generation firewall product."

"I have a lot of difficulties with the solution's Firewall Management Center (FMC) and the GUI. Neither is responsive enough and should be improved."

"Even on a smaller scale, people are finding you need HA pairs, and there's no way that the ASA can do that, at least in the virtual version."

"Nowadays, nobody is in the office, so I need to figure out how to put the firewall outside. If I could have a centralized firewall that also receives information from external locations, like peoples' home offices, that would help us consolidate everything into one appliance."

"Some of the features, like the stability, need to be improved."

"We use the FTD management platform for the boxes. The GUI that manages multiple Firepower boxes could be improved so that the user experience is better."

"You need to have a little bit of knowledge to be able to configure it. Otherwise, it would be very difficult to configure because there is no GUI. The latest software available in the market has a GUI and probably zero-touch provisioning and auto-configuration. All these things are not available in our version. You need to manually go and configure everything in the switch. In terms of new features, we would definitely want to have URL-based filtering, traffic steering, and probably a little bit steering in the bandwidth based on the per-user level and per-user group. We will definitely need some of these features in the near future."

"It is my understanding that they are in the process of discontinuing this device."

More Cisco Secure Firewall cons

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

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

"It would be really helpful to have dashboards that provide information on IOC blockings such as where and how many. It will also be good to know how many hashing files have been reported. It would also be nice to have easy access to this information. Otherwise, it's a painful, manual task."

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

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

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

"I'd like to see more data protection on the system."

"Higher levels of support are excellent but new users may need additional options."

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 pricing is flexible."

"It is too expensive for us. My organization is very small, and we have a total of ten users. We have three internal users and seven external users. The FortiGate 100D series is too expensive for renewing the licenses."

"It is expensive. You need to pay for the subscription every year, which is very expensive. The subscription includes technical support and hardware exchange in case of failure."

"Pricing is good. They offer a lot of things, the most important is the support. Every time you upgrade your license, you also get insurance for the equipment. If you have any problem with equipment, they send in new equipment."

"The pricing of the solution is very competitive."

"The pricing is fair."

"The setup cost was good. The Egyptian pound is declining, and upgrading Fortinet FortiGate yearly costs about $2000 USD, which equals one hundred Egyptian pounds. I maintain a business relationship with the vendor and receive support from them."

More Fortinet FortiGate pricing and cost advice

"I rate the product's price a seven on a scale of one to ten, where one is expensive, and ten is cheap."

"When it comes to Cisco, the price of everything is higher. Cisco firewalls are expensive, but we get support from Cisco, and that support is very active."

"The pricing of Cisco's boxes is pretty good."

"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."

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

"Pricing is high."

"Cisco is cheaper than Check Point although it is not as cheap as Fortigate. But with the latest improvements in hardware and speed, the pricing is okay."

"Cisco's prices are more or less comparable to those of other products."

More Cisco Secure Firewall pricing and cost advice

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

"The price of this solution is too high."

"It would be nice if they lowered their prices for small businesses."

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

"The pricing is expensive."

"Palo Alto Networks K2-Series is an expensive solution, the price could be reduced. They are more expensive than some of their competitors."

"When comparing Palo Alto Networks K2-Series with other solutions it is on the higher end of the price scale."

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