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.

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

"I like how we can achieve total integration."

"Fortinet FortiGate has many valuable features, such as IDS, and intrusion detection. It has security features that are in part with the technologies that are available in the market."

"The most valuable feature is the VDOM, which allows the customer to have multiple firewalls in a single campus."

"The notable features that I have found most valuable are that it includes the antivirus, and also IPS, and even SD-WAN."

"FortiGate has a very strong unified threat management system."

"Whenever I need something, Fortinet improves and updates the software for me."

"Customers are more inclined towards FortiGate because of application control, web filtering, and anti-spam features. The support from the FortiGate team is good, and price-wise, it is affordable."

"The web controls are what I appreciate about Fortinet FortiGate. We have extensive controls over areas where we could block external-facing IPs, external URLs. We can do geo-fencing with the firewalls, which is a good feature."

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."

"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."

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

"Palo Alto's App-ID is what differentiates it from other competitors."

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

"It's easy to configure."

"One of the most valuable features is Palo Alto's firewall management. We find it easier to manage the firewall centrally."

"The solution offers effective security features such as HIDS (Host-based Intrusion Detection System) in global products."

"I have found the threat profile feature valuable."

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

Cons

"I don't really have anything negative to say as far as Fortinet firewalls are concerned. If anything, they can support a user a little bit better. They can stop being so time-sensitive about how much time the support call has taken, and they can help you do it yourself."

"The solution lacks multi-language support."

"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. It will be useful for assessing our strategy and monitoring our environment without investing in FortiGate Analyzer. It would be beneficial if Fortinet could enhance the FortiGate by providing more statistical and monitoring views for a longer timeframe, rather than requiring access to FortiGate Analyzer."

"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. That's the only drawback."

"The cloud features can be improved."

"The solution could be improved by addressing limited local reporting. It requires obtaining the FortiAnalyzer for proper visibility because you can't do much from a reporting perspective with just the firewall alone."

"Fortinet FortiGate can improve the integration with Active Directory. Additionally, I would like to have a Cloud Controller, such as they do in the Cisco Meraki solution."

"Fortinet FortiGate is not very easy to use. The navigation could be improved to make it easier to use."

More Fortinet FortiGate cons

"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."

"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."

"The user monitoring could still be improved."

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

"I cannot think of anything specific to improve at the moment."

"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."

"Threat prevention could use improvement."

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

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

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

"The licensing cost is a typical complaint with many clients. The solution is expensive."

More Palo Alto Networks K2-Series cons

Pricing and Cost Advice

"The licensing costs are very low."

"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."

"Compared to other firewall products, it's a little cheaper in terms of pricing."

"The cost is too high... They have to focus on more features with less cost for the customer. If you see the market, where it's going, there are a lot of players offering more features for less cost."

"For the performance that we get, the price is reasonable. There are cheaper options, but they may not deliver the same kind of performance that we want. For the performance they provide, the price is acceptable."

"The price is fine."

"The price of FortiGate is comparable to that of most other firewall solutions and is more affordable than Cisco."

"Fortinet FortiGate is cost-efficient. Palo Alto is expensive, but Fortinet FortiGate is not."

More Fortinet FortiGate pricing and cost advice

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

"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."

"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."

"It is an expensive solution."

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

"The price of this solution is too high."

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

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

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

"Palo Alto firewalls are very expensive."

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