Manager, Information Technology Operation/Presales at TechMonarch

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.

Olivier DALOY

Group Information Systems Security Director - CISO at Faurecia

Secures users wherever they are and enable us to inspect SSL traffic, but we encountered too many issues

The solution should have no impact but it does have a bit of impact on end-users. For example, we encountered some issues in the downloads that took longer than they did without using Menlo. That is clearly not transparent for users. We expected not to have any latency when downloading anything from the internet with Menlo compared to without Menlo. We are now transitioning to another solution. The main reason for that is that managing all of the exceptions and troubleshooting all of the issues our users have had connecting to the internet has become too significant in terms of workload, compared to what we hope we will have with another solution. In other words, we hope to get the same level of protection, while reducing the number of visible bugs, issues, latencies, impacts on performance, et cetera, that we have today with Menlo. We already solved most of them, but we still have too many such instances of issues with Menlo, even though it is protecting us for sure. The weak point of the solution is that it has consumed far too much of my team's time, taking them away from operations and projects and design. It took far too much time to implement it and get rid of all of the live issues that we encountered when our users started using the solution. The good point is that I'm sure it is protecting us and it's probably protecting us more than any other solution, which is something I appreciate a lot as a CISO. But on the other hand, the number of issues reported by the users, and the amount of time that has been necessary for either my team or the infrastructure team to spend diagnosing, troubleshooting, and fixing the issues that we had with the solution was too much. And that doesn't include the need to still use our previous solution, Blue Coat, that we have kept active so that whatever is not compatible or doesn't work with Menlo, can be handled by that other solution. It is far too demanding in terms of effort and workload and even cost, at the end of the day. That is why we decided to transition to another solution. If we had known in the beginning that we would not be able to get rid of Blue Coat, we probably would not have chosen Menlo because we were planning to replace Blue Coat with something that was at least able to do the same and more. We discovered that it was able to do more but it was not able to replace it, which is an issue. It is not only a matter of cost but is also a matter of not being able to reduce the number of partners that you have to deal with. In addition, they could enhance the ability to troubleshoot. Whenever a connection going through Menlo fails for any reason, being able to troubleshoot what the configuration of Menlo should be to allow it through would help, as would knowing what level of additional risk we would be taking with that configuration.

One of the best tools for the prevention of evasive threats

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

"Previously, we were using another firewall device, Sophos. Compared to that, Fortinet FortiGate provides more features and better security."

"The firewalls are valuable for threat prevention."

"The most valuable features are the enterprise modeling and the simple interface."

"Fortinet FortiGate is the best option on the market when it comes to firewalls."

"The user interface is intuitive. Anyone can configure the firewall with little knowledge of the product. The back-end is robust with good security."

"The most useful features in Fortinet FortiGate are the security features, where we can analyze what kind of traffic is inside our network, and we also utilize ZTNA for limiting and managing our network access."

"The solution effectively controls browsing traffic."

"It is pretty straightforward to manage and has robust capabilities. I appreciate that Fortinet FortiGate can be a central controller for other Fortinet products, such as switches and access points."

More Fortinet FortiGate pros

"It has reduced security events to follow up on. While it is not 100%, there has been probably a 90% or more reduction. We were getting hit left, right, and center constantly from people browsing the Internet and hitting bad websites. It was not just bad websites that were stood up to be malicious, but good sites that were compromised."

"The fact that it is a cloud proxy solution is another feature we like. For example, if you acquire a new company, you can use it to protect that new company without the need to install anything physically on their networks."

"For us, the primary goal is protection on the web, and that's extremely important. We're not using any of the other services at this time. The web part is key to the success of the organization. It gives us the ability to protect. It can isolate. It opens the session in an isolated format so that the code isn't running locally. It is running over in the Menlo environment, not in ours. It is not running on the local computer, whereas if you were to go to a normal website, it would run Java or something else on the local machine and potentially execute the malicious code locally. So, it does give us that level of protection."

"This security technology addresses risk and enables people to conduct business without that risk, which is where the ROI is realized."

"Accessing the internet with a proxy from anywhere is the most valuable feature. It ensures that users are only able to browse legitimate websites. If they happen to go to a legitimate website with a malicious payload, the isolation feature will take care of that."

"This is a very reliable firewall and we have never had problems with it."

"The scalability of the product is quite high."

"Palo Alto has an approach that makes the configuration easier not only for the customers but also for the IT help for the customers."

"The application ID on the Palo Alto Networks K2-Series is able to understand the application traffic, and WildFire is also good."

"Everything I could possibly want has already been implanted in the new version."

"K2-Series' best features include its scalability, which is the best on the market."

"It's easy to configure."

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

More Palo Alto Networks K2-Series pros

Cons

"I'm not sure if it's something that they already have or are developing something, however, we need some dedicated features for container security."

"FortiGate can only retain logs for 24 hours or 7 days. I'm not sure if it holds them for a longer period, such as for a month."

"To the best of my knowledge, Fortinet does not have a CASB solution and Fortinet does not have a Zero trust solution."

"Fortinet FortiGate could improve by adding enhancements to FortiMail, FortiSOAR, and FortiDeceptor."

"I want some additional features. For example, I want something to ensure that when we are using Google email or Microsoft email, or Google Workspace, emails can only be accessed on designated machines given to our employees. I would like them to access data from designated machines, not from any machine. It should work for designated mobiles and laptops. I don't know if Fortinet provides something like that out of the box."

"They need faster serviceability and more security features."

"The ease of use could be improved."

"In their datasheet, they put the throughput as huge, but once you enable all the features of the box, the performance is impacted dramatically."

More Fortinet FortiGate cons

"The user monitoring could still be improved."

"Currently, I don't have a good way to see which of my rules are being used in the access control lists. I have numerous entries, but are they all still needed? A report that would show me my list of who is allowed and whether we're actually using it would be useful because I can then go clean up my list. It would be easier to manage. We would eliminate the vulnerability of unused services."

"Menlo Secure is a smaller company with limited resources and funding, which makes it challenging to compete with larger companies such as Palo and Cisco."

"We are now transitioning to another solution. The main reason for that is that managing all of the exceptions and troubleshooting all of the issues our users have had connecting to the internet has become too significant in terms of workload, compared to what we hope we will have with another solution."

"In the best of all worlds, we wouldn't have to make any exceptions. However, that is a big ask because a lot of that depends on how websites are constructed. For example, there are some very complex, application-oriented sites that we end up making exceptions for. It is really not that big an issue for us to make the exceptions. We feel like we are doing that without a huge impact on our security posture, but we do have to make some exceptions for complex sites, e.g., mostly SaaS-type sites and applications."

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

"Threat prevention could use improvement. Not just in malware exploits and C2 traffic; enhancing web traffic protection would be a great upgrade."

"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."

"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 scalability of Palo Alto Networks K2-Series is good. It is good for larger environments over smaller ones."

"Its networking features could be better."

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

More Palo Alto Networks K2-Series cons

Pricing and Cost Advice

"My experience with the pricing, setup cost, and licensing for Fortinet FortiGate is quite good. I don't have a public site, such as in Azure, where I can see the pricing. I always have to go through the distributor, and that could take some time to get the real price for each appliance."

"It has a competitive price."

"The price is okay, so far so good."

"The pricing for this solution is good."

"When comparing this solution to others, I would rate it a ten out of ten in terms of pricing. However, the issue of requiring a separate license for redundancy is a drawback, and I would rate it a nine out of ten."

"The licensing costs are very competitive."

"The product pricing is reasonable."

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

More Fortinet FortiGate pricing and cost advice

"We save a ton of money and time. Previously, the numerous hits that we were receiving from our security tools, prior to implementing them, had to all be chased down, dispositioned, and endpoints had to be reimaged. It was just a ton of effort to do all that. That is where the savings from time and money come in."

"The solution is expensive. It's more expensive than the solution I previously used. Compared with the other cloud-based solutions, it's very competitive."

"It is appropriately priced for what they're doing for us. Considering the protection provided, I feel their pricing is spot-on."

"The pricing is expensive."

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

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

"Palo Alto firewalls are very expensive."

"It is an expensive solution."

"The price of the solution is expensive."

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

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