Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

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

"I prefer FortiGate because it has a lot of other solutions embedded within it and is the easiest for our technicians to operate."
"I have found the decryption of Fortinet FortiGate IPS very good. It's called SSL deep inspection, it's working very well. This is how you decrypt access and traffic, and it is through the IPS antivirus center. Additionally, the UI is user-friendly."
"At least one part I am headache free that I don't have to categorize all the websites and that security has been pre-categorized by the people, and that the services are getting updated."
"Initial setup is straightforward; there weren't too many issues with setting it up and it takes one hour or so."
"Fortinet provides us all that we need for security."
"Customer Service: Very good. Technical Support: Very good."
"FortiGate tech support is very good because we get immediate support from them; for example, whenever we raise a ticket, we get an immediate response, and someone attends to help."
"The web tutor and automatic rules by schedule are good features."
"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"We have found pretty much all the features of the solution to be valuable."
"What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it. I had an excellent experience with OPNsense, which helped me achieve the targets I wanted."
"We have found pretty much all the features of the solution to be valuable."
"Based on my experience, the main benefits OPNsense provides for me are due to the limitation in getting financials to implement the most marketable solutions available in the market, which pushed me to find other open-source-related or cheaper solutions, and that is how I came upon OPNsense and pfSense, but OPNsense was the choice in this decision, providing a simple but also effective solution on a low budget."
"With the VPN solutions, it is possible to cover up all the scenarios which we have."
"It is a very good solution. I like the dashboard. I can see what is going on and manage it as I like it."
"Offering this solution has provided some of our clients with firewall protection and UTM, which basically just protects them from the internet."
"It was easy to initially deploy it."
 

Cons

"The solution could maybe use more integration with artificial intelligence to be more proactive."
"Sometimes it's super hard to figure out what's wrong with a FortiGate VPN unless you know the commands on the CLI to see the flow and how to interpret it."
"The tech support is not excellent; this is where Fortinet saves money compared to others... But plenty of free, clear and public documentation is available and this compensates for the most part the tech support shortcomings."
"In the balance between links feature normally you can just choose one option to balance. It would be better for the solution to have more than one option, preferably three."
"I often ask for help from the local provider. I haven't found the required efficient help."
"There are some issues with security features and aspects like logs not being up to the mark."
"Overall it is not scalable."
"I wish that they could integrate zero-trust technology into Fortinet FortiGate. I am not sure whether it has been done already, but if they could implement that, it would help significantly."
"While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet."
"The support service isn't very accessible, so you have to look at the forums to solve some issues."
"There is room for improvement in SSL inspection."
"They should improve IPEs for security in the future."
"The feature that I would like to see in the next release, I think, would be to improve the VPN (Virtual Private Network) selection."
"There are issues with stability and reliability."
"OPNsense could be improved with a better wizard, as when I first installed it, it seemed difficult to know where to go."
"There are issues with stability and reliability."
"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

"I would rate the pricing a seven out of ten"
"The price for the device and software is high. However, the solution is of good quality and has a lot of features."
"The solution requires a license annually, it is not a user license, you can have as many users as your want. I must renew the license regularly per device."
"It's a year based license."
"Our licensing costs are on a yearly basis."
"The license is too expensive to renew. The license renewal process is also complex."
"I give the pricing of the solution a six out of ten."
"We purchased a five-year bundle package, which worked out cheaper than competing solutions."
"We are using the paid version."
"OPNsense is a well known open-source tool."
"It costs about $1000."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"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."
"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."
"There are no licensing costs for OPNsence."
"OPNsense is open source software so at this time it is free for us to use."
