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.

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.

Quotes from Members

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

Pros

"Application control and the web filter are the best features of Fortinet FortiGate."

"The network security and cloud security are most valuable."

"We are very happy with the general bandwidth agility we have seen from one website to another website."

"Its administrative panel is very intuitive and simple. It is simpler than the other solutions that we had. As an administrator, we are always looking for the easiest solution to manage network policies. We are able to filter everything on our network and also use the VPN feature, which is important these days when people are working remotely during COVID."

"Fortinet FortiGate is a simple solution, and the integration with other solutions in the Fortinet portfolio, such as the Security Fabric integration, is competitive."

"The solution is very, very easy to use, the user interface is very nice, the product offers pretty good customization, configuration has been straightforward and simple, the reporting is quite good, the initial setup is straightforward as well, and we've found the pricing to be pretty good."

"Mainly the FortiGate reporting system is very good. It guides us through all the expectations of security. Fortinet provides us all that we need for security. Also, Fortinet FortiGate is a next-generation firewall. It is much more advanced than others."

"The best feature of Fortinet FortiGate is the IPS or IDS implementation. I appreciate most the agility or the flexibility to create hashes to block incoming threats, and I can integrate with third-party threat intelligence with our FortiGate."

More Fortinet FortiGate pros

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

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

"OPNsense is easy to scale when running on the hardware."

"OPNsense is a great tool for problem-solving with a VPN."

"I mostly rely on the solution's network intrusion detection and prevention system, along with other systems, CMs, and log management."

"The technical support is very good."

"The system in general is quite flexible."

"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."

More OPNsense pros

"So far, the performance and reliability of the product have supported our company's critical network traffic."

"It enables us to not only detect but also prevent various types of incoming threats, allowing us to take appropriate corrective actions and exercise control over the network."

"Sangfor has the best capabilities for securing connections, securing web browsers, securing servers, and general threat protection."

"I think this solution is a very good example of a proactive solution that can detect problems and immediately fix the problems or issues."

"You might try Sangfor if you are on a tight budget. The price is affordable, and Sangfor offers a lot of features. We don't have any complaints about Sangfor."

"Sangfor NGAF works accordingly with our customers, the solution has good performance, is easy to use, and integrates well with the endpoints."

"In four steps one can configure the entire firewall."

"Sangfor is a good solution that provides a WAF and firewall solution. Most other vendors, like Sophos and Fortinet and Cisco, only provide one solution. That's a valuable feature of Sangfor."

More Sangfor NGAF pros

Cons

"I would like to see improvements in Fortinet FortiGate regarding the active-active scenario. The active-active scenario is supported but not recommended, whereas other vendors are implementing active-active without issues."

"We understand that FortiGate cannot be standalone without others, such as FortiManager, so for small businesses, if FortiGate can provide something similar to FortiManager, it will be better."

"The scalability could be better."

"They could improve vulnerability scanning."

"For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial."

"The only problem that we have here in China is that the whole subscription process on Fortinet is a little bit difficult if you are doing it from China."

"It would be good if they had fewer updates."

"The speed of the detection could be improved. The prevention mechanisms and implementation are not easy and could be better."

More Fortinet FortiGate cons

"They should improve IPEs for security in the future."

"When using the solution at the beginning was difficult. There was a steep learning curve."

"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."

"I would like to see better SD-WAN performance."

"On the customer-side, because I'm a small business, I need a cheaper or free solution option."

"There are issues with stability and reliability."

"The interface of the solution is an area with shortcomings."

"The monitoring is a little complicated and I have tried to use a plug-in, but it's quite complicated to configure."

More OPNsense cons

"The web interface needs to be improved, making it more user-friendly."

"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."

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

"Our experience with its customer support was quite challenging."

"Sangfor could improve by providing better real-time reporting, as the current reports don't offer the level of detail we need, especially for runtime insights."

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

"The support offered by the product has certain shortcomings where improvements are required. The knowledge levels and response time of the support team need improvement."

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

More Sangfor NGAF cons

Pricing and Cost Advice

"The product is expensive."

"Fortinet FortiGate has different licensing models, depending on what you're going to do. Services included would depend on the license model. Licenses can be renewed annually."

"It is an inexpensive solution."

"I give the pricing of the solution a six out of ten."

"When I look around at other products, such as Sophos, Fortinet FortiGate is 20% to 30% more expensive with our current cost."

"The setup cost was good. The Egyptian pound is declining, and upgrading Fortinet FortiGate yearly costs about $2000 USD, which equals one hundred Egyptian pounds. I maintain a business relationship with the vendor and receive support from them."

"The price is really low. It's cheap in comparison to the cost of Cisco or CheckPoint, for example."

"The pricing or licensing of Fortinet FortiGate is quite effective as it offers different bundles that aggregate most required features, while also allowing clients the option to select specific components alone."

More Fortinet FortiGate pricing and cost advice

"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."

"As an appliance, it's in the medium price range."

"There are no licensing costs for OPNsence."

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

"It costs about $1000."

"It's a free solution."

"It is open source and free."

"It's not expensive."

More OPNsense pricing and cost advice

"For four to five physical appliances for a licensed firewall, it costs approximately $4,000."

"The pricing is reasonable."

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

"It is one of the cheapest tools in the market."

"In my opinion, the price of the tool is good in the Pakistani market. We can easily get discounts if needed."

"The license of Sangfor NGAF can be purchased at different interval lengths, such as annually or three years. They offer a range of packages to choose from, such as combo or hybrid packages. We are using the complete solution package which includes IM, NGF and SSL VPN, and WAF."

"Sangfor NGAF is a cheaply priced product, especially if I consider the previous product that was used in my company."

"Price-wise, I would not consider Sangfor NGAF to be a cheap product. It is an expensive firewall solution, though not as expensive as something like Palo Alto, which is costly. However, the higher price point is justifiable given the feature set the tool provides that other firewalls may not offer in a single dedicated appliance."
