Enables customers to manage security effortlessly with intuitive features and easy integration

In terms of improvements for Fortinet FortiGate, they could offer evaluation licenses, as compared to Meraki, which provides a 90-day evaluation. In Fortinet FortiGate, they do not provide standard evaluation licenses; instead, we need to request them from the OEM through the account manager for POCs. If we want to conduct a demo, we need to work with real hardware. In comparison to Cisco, we have DCloud, which helps with providing demos to customers, but in Meraki, I need to reach out to them, book a lab, and they need to provide all the hardware. I need remote access and L3 engineers to program it; only then can I offer a real-time demo to the customer.

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

"Fortinet FortiGate is a very stable solution."

"It does not require a lot of maintenance."

"I've found the solution to be very good."

"FortiGate firewalls pay for themselves."

"This product is definitely scalable."

"It is easy to use and update the software version. It is also useful for integration with other Fortinet products, because my office and company use Fortinet solutions."

"Fortinet FortiGate IPS has an easy-to-use interface and configuration."

"One of the best features of Fortinet FortiGate is that it's a very powerful equipment that gives many security features in a single box with good performance, and the user interface is friendly to use and configure."

More Fortinet FortiGate pros

"Offering this solution has provided some of our clients with firewall protection and UTM, which basically just protects them from the internet."

"Its user interface is one of the best interfaces I have used."

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

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

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

"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."

"The initial implementation process is simple."

"I feel that its valuable features are that it is simple and free."

More OPNsense pros

"It was easy to initially deploy it."

Cons

"There could be more modifications."

"We would like to have the ability to disable some of the security functionalities."

"The initial setup is complex."

"Another issue is how deduplication services don't work reliably after enabling deduplication on Fortinet."

"Fortinet FortiGate could improve by having more storage in the hardware for log data."

"Fortinet FortiGate can be integrated with different platforms. They have integrations in place, but I can't say they're 100%."

"It should be more stable. There should be full integration within Fortinet products themselves as well as with other third-party products. Especially when you're not dealing with SIEM and the correlation of the security box, we want Fortinet to be able to share that information with as many other products as it can."

"There are problems with the custom reporting of the unique traffic. The data is there, but it is too difficult for us to extract."

More Fortinet FortiGate cons

"My mark for OPNsense technical support is a four for the free version since they do not care when they realize you are using the free version; they just ghost on you."

"There are a few weaknesses. For example, there is a lack of some features that I have in certain commercial products."

"There are issues with stability and reliability."

"The reporting part could be better."

"The feature that I would like to see in the next release, I think, would be to improve the VPN (Virtual Private Network) selection."

"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."

"The IPS solution could be more reliable."

"The solution could be more secure."

More OPNsense cons

"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

"Fortinet Secure SD-WAN delivered the lowest total cost of ownership (TCO) per Mbps among all other vendors."

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

"The pricing is better compared to other solutions like Check Point, Arista, or Cisco."

"The tool's pricing is neither cheap nor expensive. Overall, I find it to be competitive in the market."

"Fortinet is reasonable in pricing and licensing. Overall, FortiGate is affordable. The licensing fee can be a little high, depending on the budget for your project."

"There is a license required to use Fortinet FortiGate with all the features. It has to be updated with the threats on an ongoing basis for the signatures to prevent threats and a license is needed to receive those security updates."

"In the Asian economy in which we operate, FortiGate is expensive."

"It is too expensive for us. My organization is very small, and we have a total of ten users. We have three internal users and seven external users. The FortiGate 100D series is too expensive for renewing the licenses."

More Fortinet FortiGate pricing and cost advice

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

"The price of OPNsense is good."

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

"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."

"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."

"It is open source and free."

"It is free."

"There are no licensing costs for OPNsence."
