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.

User-Friendly, improves security, and gives me more control over my VoIP

We purchased the solution and we are partners. I haven't had a chance to go through all of the features and what this solution offers, but I think that it has an integrated VPN. I am looking forward to using another VPN. I am anxious to see it, as we are going to set that up for one of the clients. At this time, I am not able to add any comments on how this solution can be improved, because this solution does what it is asked to do. I would rate this solution an eight out of ten.

Has helped simulate enterprise security setups and strengthens network segmentation practices

For my capstone, I use OPNsense for my project and its broader benefits for enterprise and cybersecurity context. OPNsense is an open source based firewall and routing platform. It offers enterprise-grade features such as intrusion detection and prevention system, VPN support, traffic shaping, and web filtering, all without license cost. This platform has a modular design, a clean web-based GUI, and frequent updates that prioritize security and usability. It competes with commercial firewalls such as Cisco ASA, FortiGate, and Palo Alto, but stands out because it's community-driven, cost-effective, and transparent. I find OPNsense's feature of acting as a central firewall and gateway most valuable, providing robust point segmentation between the internal network and DMZs in my capstone project, intrusion detection to monitor malicious traffic, VPN services for secure remote access, and logging and monitoring for compliance and auditing. This allows me to simulate a real-world enterprise environment on a smaller scale, demonstrating both security hardening and network efficiency. OPNsense impacts my projects and home network positively because its cost-effectiveness is perfect for lab and enterprise setup without expensive licensing. The flexibility, easy VLAN and DMZ configuration supports different zones such as web servers, mail servers, and log servers. The security-first design for IDS/IPS integration helps me showcase modern defense-in-depth strategies. The user-friendly management through the web GUI makes it possible to manage complex firewall rules clearly, which is critical when documenting and presenting a capstone. Scalability is also an advantage. Although my project is lab-based, OPNsense can scale into production deployments in SMBs and enterprise.

Quotes from Members

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

Pros

"The solution provides an easy way to filter information and Fortinet lab is a great place to discover new things."

"The firewall is pretty good if you understand how to use it. It performs at a very high level, and we are loving it."

"Fortinet offers the latest versions to cater to the needs of enterprises."

"FortiGate Secure SD-WAN includes best-of-breed next-generation firewall (NGFW) security, SD-WAN, advanced routing, and WAN optimization capabilities, delivering a security-driven networking WAN edge transformation in a unified offering."

"The most valuable features of the FortiGate firewall include SSL inspection, VPN functionality, and threat intelligence features for preventing threats."

"The scalability is easy with switches and access points that are basically plug-and-play for the most part."

"It's simple to operate and use."

"Our project needs to link two sides through the internet. One of these was in Cairo and the other in another city. We used FortiGate as the integrating solution between the two locations, i.e. the Fortinet 30E & 100E."

More Fortinet FortiGate pros

"This solution is user-friendly."

"The interface and the dashboard are the most valuable features of this solution."

"The system in general is quite flexible."

"We can open a new VPN connection easily. It's much easier than with Fortinet in our experience."

"URL blocking, Wireguard, Tail Scale, Engine Blocker, and VPN are the most valuable features for me."

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

"It's open source."

"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."

More OPNsense pros

Cons

"Security is a continuous process. In every product, there is a requirement for improvement. Its pricing should also be improved according to Indian market requirements. They must also improve on the reporting part. Its reporting can be more precise. If we can get a real-time report in a specific format, it will be helpful for customers to know about the current status of their security."

"FortiGate needs to be elastic to the market's trends. It should be easy for SMBs to get the solution."

"It would be helpful to have a better tool for migrating all policy rules using an automatic script."

"There is room for improvement related to the logging and reporting aspect."

"The platform's interface could improve."

"One area for improvement is the licensing policy. If support licenses are not renewed, the product's functionality ceases, which can be disruptive."

"I would like reporting to be improved and should offer a lot more tools to monitor the products."

"I would like to see improvements in the product's application rules."

More Fortinet FortiGate cons

"I haven't seen any feature that will allow me direct authentication for a VPN solution."

"I think the most important thing is that it should be easily accessible, but currently, that doesn't seem to be the case. We need a hardware platform that's based on common standards and open computing principles, which would be like a commodity and benefit us greatly."

"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."

"The interface of the solution is an area with shortcomings."

"The interface needs to be simplified. It is not user-friendly."

"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."

"There are issues with stability and reliability."

"The ability to set the VPN IP address would be a welcome addition."

"OPNsense could be improved with a better wizard, as when I first installed it, it seemed difficult to know where to go."

More OPNsense cons

Pricing and Cost Advice

"We have the full version of Fortinet FortiGate and we are on a three-year contract with a commitment of five years."

"It's an expensive solution."

"We purchased a five-year bundle package, which worked out cheaper than competing solutions."

"The solution is very expensive so pricing is rated a one out of ten."

"I think the price of Fortinet FortiGate is very reasonable."

"Fortinet FortiGate gives you most of the features in one license."

"The price of Fortinet FortiGate is the lowest in the market."

"The license of Fortinet FortiGate should be reduced."

More Fortinet FortiGate pricing and cost advice

Information not available

"It is free."

"I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups."

"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 open source software so at this time it is free for us 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."

"OPNsense is a well known open-source tool."

"As an appliance, it's in the medium price range."

"The price of OPNsense is good."
