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.

Robust network security and management offering a user-friendly interface, open-source flexibility, and cost-effectiveness, with challenges regarding initial setup and the absence of official support

The interface is user-friendly, but there's room for improvement in terms of intuitiveness. The bundle management aspect requires additional attention to make it more intuitive, especially for inspecting high-level traffic. This is crucial, especially for larger companies where the existing features might not be the most optimal choice, given limitations like printer constraints. For high availability, it's crucial to have a method in place where a designated component oversees the entire process. Given that OPNsense plays a pivotal role as a firewall, safeguarding against various threats, having a reliable backup ensures uninterrupted protection even if unforeseen events impact the primary virtual machine. It would be beneficial if OPNsense supported additional virtualization platforms like Hyper-V from Microsoft and VMware, similar to how Kaspersky has integrated them.

Quotes from Members

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

Pros

"The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with."

"The application control features, such as Facebook blocking and Spotify blocking, are the most valuable."

"The most valuable features are the possibility of having one fabric for switching on security."

"Secure, user-friendly, stable, and scalable network security solution. Installation is straightforward."

"Fortinet FortiGate is a very good next-generation firewall."

"It is a safe product."

"Overall, I would rate Fortinet FortiGate a ten out of ten."

"There are great templates, so you don't have to customize them if you don't want to. You do have the option to custom create some folders and some reports, however, with what is there, you don't really need to go through extra effort, as they already give you a lot of predefined views of reports and so forth."

More Fortinet FortiGate pros

"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."

"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."

"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."

"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 solution is user-friendly and easy to configure."

"We have been operating here in our lab for several months, and everything appears to be extremely stable."

"The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used."

"The initial setup is easy. It only takes 15-30 minutes to deploy."

"I have found the solution has some great features overall, such as guest access capabilities, dashboards, and ease of use. There is plenty of documentation and support and it has the plugins that I needed."

"I mostly rely on the solution's network intrusion detection and prevention system, along with other systems, CMs, and log management."

"The most valuable features in OPNsense are reporting and visibility."

"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."

More OPNsense pros

Cons

"Fortinet FortiGate is a very good device overall, though it can be improved in certain areas regarding the licenses, particularly the big one called unified threat management, which has many capabilities."

"They could simplify their deployment process, especially when customers have existing devices."

"Cisco Meraki products are rising very quickly in the cloud and the connected era. Meraki products offer much better ROI, upgradability, and manageability."

"We would like to see a better training platform implemented."

"In the scenarios coming from Sophos, it has not."

"I think the only issue that needs improvement is the interface."

"It's one of the more expensive brands."

"We would like to see an upgrade to the VPN feature, we are using the VPN from outside of our office and there is a limitation to 10 connections, more connections would be suitable."

More Fortinet FortiGate cons

"The user monitoring could still be improved."

"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."

"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."

"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."

"I would like better documentation concerning the provided packages and their integration."

"The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform."

"The IPS solution could be more reliable."

"The scalability needs improvement."

"The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs."

"When using the solution at the beginning was difficult. There was a steep learning curve."

"I would like to see better SD-WAN performance."

More OPNsense cons

Pricing and Cost Advice

"No comment."

"It is very cost-effective. You get features similar to other firewalls, such as Palo Alto, but at a lower price."

"The license is yearly. We pay for the top end. It's called 360."

"The value is the capability of having multiple services with one unique license, not having the limitation per user licensing schema, like other vendors."

"The pricing for the product is alright."

"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."

"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."

"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

"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 costs about $1000."

"I've used the free version. My computer with two network cards at home allows me to try as many different software options as I want. I did pay for the license, but it was for the Zenarmor license, which is the packet inspection tool. They use AI for packet inspection, which integrates with OPNsense and pfSense."

"OPNsense is an open-source solution and it is free to use."

"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."

"It is open source and free."

"It's not expensive."

"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."

"The solution is not expensive."
