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.

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

"The GUI configuration is its most valuable feature"
"Fortinet FortiGate has SD-WAN, FortiView, antivirus, sandbox, and IPS, which are generally well-known features."
"FortiGate SD-WAN facilitated a smooth transition for our customers between their two internet service providers, ensuring uninterrupted connectivity without any downtime."
"I find that Fortinet FortiGate is pretty easy to use and integrated, offering many features in one box at a decent price compared to other enterprise vendors."
"The product is user-friendly and not complex."
"We’ve gone from only selling Fortinet FortiGate as an accessory to creating an entire department in our business dedicated to selling Fortinet products in the span of three years."
"The firewalls are valuable for threat prevention."
"The pricing is excellent. It's much less expensive than Cisco."
"OPNsense impacts my projects and home network positively because its cost-effectiveness is perfect for lab and enterprise setup without expensive licensing, and the flexibility, easy VLAN and DMZ configuration supports different zones such as web servers, mail servers, and log servers."
"It has firewall and VPN capabilities, which are very valuable features."
"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."
"I feel that its valuable features are that it is simple and free."
"The system in general is quite flexible."
"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"The tool's integration is more like a button press."
"We have been operating here in our lab for several months, and everything appears to be extremely stable."
"It was easy to initially deploy it."
 

Cons

"Cisco Meraki products are rising very quickly in the cloud and the connected era. Meraki products offer much better ROI, upgradability, and manageability."
"The support structure needs to be improved because every time we contact them, there is a delay in the response."
"Some of the filtering is not robust, you can escape it with a VPN. Some of the users bypass some of the filters. It catches some but it also misses some, that area could be improved. It's functioning reasonably but there's room for improvement in that area."
"It could use better throughput on some of the smaller boxes for the branch offices."
"They could improve the response time and quality of support."
"It is essential to leverage its capabilities more professionally to achieve an even higher level of security."
"Their software support needs improvement. I would prefer to have better support for bug fixes. Sometimes, we open a ticket, and it is very difficult to get a solution. Specifically, we are not at all happy with their support for load balancing."
"The pricing could be reduced or include the first year warranty."
"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."
"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."
"An area for improvement in OPNsense is the hardware, which needs to be updated more frequently. DNS blocking is another good feature I want to be added to the solution. pfSense has a peer-blocking feature that I also want to see in OPNsense."
"There is room for improvement in SSL inspection."
"On the customer-side, because I'm a small business, I need a cheaper or free solution option."
"There are some add-ons that need enhancements to make management easier for users, especially the reporting features. Some reports don't show the level of detail I'm looking for, and I've had trouble installing certain add-ons, especially for Internet bandwidth shaping within my company."
"The ability to set the VPN IP address would be a welcome addition."
"The documentation should be clearer because I faced some difficulties navigating many options."
"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

"The price range is quite acceptable and normal."
"The solution is more expensive than Sophos. It could be cheaper. The licensing is on a yearly basis. We have had it for about three years. We must only pay extra for the license, additional requirements, and the hardware box."
"The solution's pricing is competitive."
"FortiGate Next Generation Firewall is a very cheap solution."
"Their licensing costs are annual. The UTM feature license along with their support is called FortiCare. We include that as a part of the annual maintenance cost. Palo Alto or Juniper also have an annual subscription charge for UTM. Price, of course, can always be more competitive, but it is not the most expensive product. The price-performance ratio is quite high for FortiGate."
"It's very competitive."
"The price is high compared to some of the other solutions."
"Fortinet bundles FortiGate with other products and because of this, the price is a little expensive to some SMB enterprises."
"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."
"We are using the paid version."
"It costs about $1000."
"OPNsense is an open-source solution and it is free to use."
"I would rate the pricing three out of ten."
"OPNsense is open source software so at this time it is free for us to use."
"The price of OPNsense is good."
"It's a free solution."
