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.

Enhanced threat detection with integrated security features and good support

We are using application firewalling, WAF, and SD-WAN. The capabilities are mostly within the box. For example, you will get web application firewall WAF as part and parcel of this. SD-WAN is also bundled. It integrates with their SIEM and SOAR solutions very nicely. Lastly, the pricing point is very cost-efficient as well.

Cons

"In FortiGate Next Generation Firewall (NGFW), my concern regarding improvements is the licensing model."

"To improve Fortinet FortiGate, I think they need to improve the software and make updates more quickly, rather than taking a long time to update the software or firmware."

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

"The stability of Fortinet FortiGate could improve."

"There is room for improvement in pricing."

"The user interface needs a bit of upgrading."

More Fortinet FortiGate cons

"The documentation should be clearer because I faced some difficulties navigating many options."

"Pricing in my opinion is just too expensive. It makes no sense. It moves in the direction of a monopoly."

"In our experience, OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."

"It does not offer any recommendations on how to mitigate or control attacks."

"Sangfor NGAF could improve the policies and default criteria. They could be much better."

"I would be happy if Sangfor developed a firewall designed specifically for home use, as well as for small businesses such as clinics and so on."

"They need to improve their research team and they need to study their data to analyze it and build the product."

"An area for improvement would be the number of ports defined on the box."

"Scalability for any network device is not very easy in terms of vertical scalability."

"We have deployed many firewalls and have faced two or three faulty devices that we have to replace over a year because their power supply was faulty."

More Sangfor NGAF cons

Pricing and Cost Advice

"The price range is quite acceptable and normal."

"FortiGate's pricing falls within the mid-range when compared to other leading firewall solutions."

"I think that the pricing is fair."

"The pricing depends on the FortiGate model we are using, ranging from $3,000 to $20,000 US dollars."

"I do not have first-hand experience with the rice of Fortinet FortiGate, but I have heard the price was reasonable."

"The price for the device and software is high. However, the solution is of good quality and has a lot of features."

"The cost is too high... They have to focus on more features with less cost for the customer. If you see the market, where it's going, there are a lot of players offering more features for less cost."

"It is cost-effective, and provides a good value for your money. The pricing, and license renewal, is very reasonable for us."

More Fortinet FortiGate pricing and cost advice

"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."

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

"The solution is not expensive."

"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."

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

"It's not expensive."

"We are not paying any licensing fees. OPNsense is completely free for us."

"We are using the paid version."

More OPNsense pricing and cost advice

"The solution has a TCO that is 32% to 50% less than Sophos, Fortinet, and SonicWall."

"I rate the product price as one on a scale of one to ten, where one is low price and ten is high price."

"We purchased one year technical support and return to factory support, and we also purchased one-year technical support services. So those were additional."

"If one is very cheap and ten is very expensive, I rate the tool's price as three out of ten."

"The price is unmatcheable."

"For over 2000 users, the cost is around 5000 to 6000 USD. If you want a web application firewall, you have to purchase an additional license for it."

"The price falls in the mid-range, neither exceptionally low nor high."

"If you know you have around 200+ computer users on your network, then the Sangfor NGAF 5200-F-I model would be the minimum recommended model for that amount of users. This model includes modules for packet filtering, deep packet inspection, malware scanning, DSCP filtration, and many other features."
