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

"The user interface is intuitive. Anyone can configure the firewall with little knowledge of the product. The back-end is robust with good security."

"Fortinet FortiGate has several valuable features; the configuration and policy setup are easy to implement, and there are embedded features including DLP, WAF, and proxy capabilities with security profiles for various functions."

"Fortinet FortiGate positively provides my clients' organizations with a high return on investment."

"Unified Threat Management (UTM) features."

"You can integrate certain other services with FortiGate and use additional threat intelligence services because they allow you to combine various solutions, enhancing your overall security."

"The solution’s initial setup is very easy."

"The most valuable feature of Fortinet FortiGate is load balancing. It can provide central management and VPNA. Additionally, it has enhanced our security environment."

"Its usability is good. We can easily navigate the system, and we have a very good user experience."

More Fortinet FortiGate pros

"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."

"The DNS-level filtering is impressive for thwarting time scanners."

"The solution has high availability."

"It's more secure and more reliable."

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

"I find the solution to be user-friendly. It has a lot of reports and easy settings."

"The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed."

"We saved up to half a million Egyptian pounds, which is nearly $100,000 yearly on licensing or subscription using this kind of software, and the network attacks reduced by approximately 60% after using that, even without customizing the custom configuration yet."

More OPNsense pros

"It seems to be a durable, stable product."

"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."

"The built-in features function as intended, providing exceptional value."

"Sangfor NGAF's standout feature is its powerful application control, enabling precise restrictions on mobile user access to approved applications."

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

"The price versus value is good because the solution is less expensive than Sophos, Fortinet, or SonicWall."

"The capabilities are mostly within the box."

"The stability of Sangfor NGAF is good."

More Sangfor NGAF pros

Cons

"The room for improvement is about the global delivery time period. Usually I need to wait for almost one month to deliver it overseas. So if you can shorten the deliver time it'd be great."

"One of the main reasons we're considering switching from FortiGate is because many companies have a lot of features and you don't have to pay for."

"When we cluster the two Fortinet FortiGate boxes together we have some issues."

"There could be more integration between the logging and analytical platforms to make it more seamless and integrated."

"I would rate the technical support of Fortinet FortiGate as a five because it is not as strong as Cisco. Additionally, the turnaround time is very high compared to Cisco."

"The area that Fortinet may improve is customer support."

"Security level could be increased."

"Its reporting capabilities can be improved. It should have some out-of-the-box reporting capabilities and some degree of customization. The basic reporting that it currently has is not sufficient to create more usable reports. It needs some sort of out-of-the-box reporting. They try to make customers purchase FortiAnalyzer for this kind of reporting, which is an additional cost. Other firewall vendors, such as SonicWall and Sophos, provide this sort of reporting without any additional cost."

More Fortinet FortiGate cons

"OPNsense could be improved with a better wizard, as when I first installed it, it seemed difficult to know where to go."

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

"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 solution could be more secure."

"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."

"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."

"I would like better documentation concerning the provided packages and their integration."

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

More OPNsense cons

"The reporting and log management could be improved."

"The cost of licensing is very high compared to other firewalls available here. There should be improvements in hardware scalability, allowing for more storage and memory capacity."

"The support for YouTube or the Internet is not enough."

"An area of improvement for Sangfor NGAF could be in the field of reporting and logging."

"The setup phase is quite complex."

"There is room for improvement in dependency on certain infrastructure, like the DNS dependency on the current DNS server that the company has. It should be standalone. It should not depend on any other DNS server."

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

"Sangfor NGAF could improve by refining its application control policies, especially in addressing challenges with certain types of applications."

More Sangfor NGAF cons

Pricing and Cost Advice

"Go for long term pricing negotiated at the time of purchase."

"The price of Fortinet FortiGate is better than Cisco, Check Point, and Palo Alto. In terms of pricing, it's probably a better-priced firewall solution overall."

"A year or two years back, its price was competitive and reasonable. That was one of the reasons that people easily switched to Fortinet. Over the last two years, the prices have increased drastically. However, the prices of others have also increased. An advantage is there from the price point but not as much as it was previously."

"When you look at these end security systems and firewalls, these firewalls even five years ago were $50,000 or perhaps $25,000 to implement in some types of customer sites. Now we're talking about tools that are $1,000. In this case, it might have been $500 or something like that."

"The main reason we chose Fortinet FortiGate was that the price was better than the competition."

"We pay about $4,000 for a yearly license, and there aren't any additional fees."

"The pricing is perfect."

"The price of the license and warranty can be better because it is very expensive."

More Fortinet FortiGate pricing and cost advice

"The solution is not expensive."

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

"It is free."

"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."

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

"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."

"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."

"It is open source and free."

More OPNsense pricing and cost advice

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

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

"Sangfor is cheaper than competing vendors."

"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."

"The price could be more competitive."

"When it comes to the price of firewall solutions, Sangfor NGAF takes the cake."

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

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