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.

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.
Himanshu-Sharma - PeerSpot reviewer
Senior Engineer at Qualic
Offers good scalability and monitoring features
There is room for improvement in the UI. They can improve it by making it so that everything is in one place, so we don't have to jump around to different pages. For example, if we're creating a rule, we should be able to do everything on the same page. Just a drop-down thing or something. This would improve productivity.

Quotes from Members

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

Pros

"I find Fortinet FortiGate to be quite stable, as I have never heard of any issues where they broke or malfunctioned; they are always working."
"The initial setup of Fortinet FortiGate was straightforward."
"In terms of ROI, they're inexpensive, and because they're inexpensive, they're just everywhere, in the Federal Government, schools, everywhere where budgets are fairly tight, and it is a very good product."
"FortiGate SWG's most valuable feature is integration with vulnerability management."
"The most valuable feature of the solution revolves around SSL VPN."
"It has very easy management and an amazing ETM configuration."
"It increases security posture and is helpful for firewall reporting, intrusion protection, web filtering, and SD-WAN implementation."
"Two aspects I'm happy with regarding Fortinet FortiGate firewall are the easy user interface and its resilience during power interruptions."
"We have found pretty much all the features of the solution to be valuable."
"URL blocking, Wireguard, Tail Scale, Engine Blocker, and VPN are the most valuable features for me."
"The solution has high availability."
"The most valuable features in OPNsense are reporting and visibility."
"I have found the solution has some great features overall, such as guest access capabilities, dashboards, and ease of use, with plenty of documentation and support and the plugins that I needed."
"The most valuable thing about this product is that it is very easy to use, the graphic user interface is very good, and it is user-friendly."
"OPNsense is highly stable."
"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."
"It was easy to initially deploy it."
 

Cons

"Maybe they could make some features more accessible, such as a way to translate directions between two networks that share the same subnets."
"The anti-malware engine could use an upgrade."
"The product has to be upgraded every few weeks."
"There have been several vulnerabilities in the firewall. It is hackable, some of the images are hackable."
"It should have a better pricing plan. It is too expensive. It should also have a more granular view of the attack. I don't have FortiAnalyzer, and it is difficult for me to have a complete view when there is an attack on my server."
"It claims it does DLP, but the degree and level of controls are very basic."
"The solution could maybe use more integration with artificial intelligence to be more proactive."
"The cloud management and automation capability could be improved."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"Its interface should be a little bit better."
"The reporting part could be better."
"The solution would not be suitable for anything large-scale."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"OPNsense could be improved with a better wizard, as when I first installed it, it seemed difficult to know where to go."
"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."
"There should be more technical documentation."
"There is room for improvement in the UI. They can improve it by making it so that everything is in one place, so we don't have to jump around to different pages."
 

Pricing and Cost Advice

"We pay $500 per year for the license."
"FortiGate SWG is a cost-effective solution well-suited for organisations of all sizes."
"Its price is reasonable. They have a clear pricing policy. It is not complicated by the number of VPN users at a time. We know what the price is. The yearly subscription for the security license is rather high, but it is all included for whatever number of users you have and the kind of functions you need."
"The price of FortiGate is comparable to that of most other firewall solutions and is more affordable than Cisco."
"If you purchase a one-year subscription with the hardware and then you want to renew for the second year, it is very costly."
"Although the solution's pricing is high, compared with other products, it may be cheap."
"The pricing is better compared to other solutions like Check Point, Arista, or Cisco."
"The cost has increased since the update so I would rate it eight out of ten."
"OPNsense is open source software so at this time it is free for us to use."
"We are using the paid version."
"The solution is not expensive."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"The price of OPNsense is good."
"I would rate the pricing three out of ten."
"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."
"Its pricing is unbeatable in comparison to other firewalls. You can have a small instance that could be €80 a month with the hardware underneath. Azure Firewall and FortiGate are out of the question at this price. If you are on a public cloud, you need the underlying infrastructure. Other than that, there is no additional cost. If you have it on-prem, you have to buy the server or the appliance. The hardware cost is replaced with the infrastructure cost in the cloud. You also have costs for the public IPs and underlying VMs, but that's not related to OPNsense. It would be the same for a FortiGate deployment on Azure. You need a FortiGate license, and you need the underlying infrastructure that scales up depending on your needs."
