Process-Level CPU Visibility: Introduce detailed CPU-usage metrics per subsystem (e.g., IPS engine, logging) so administrators can quickly identify and address performance spikes.

Analytics with FortiAnalyzer. Being able to pull in logs not just from our FortiGates but from all our other firewalls and then get them in one view has been a game changer. Whether I’m building an executive dashboard or doing a deep dive forensics session, I get everything I need without navigating consoles.Straightforward Application Control. FortiGate spots and blocks unwanted apps (eq. like BitTorrent or streaming services) with accuracy. Segmentation with VDOMs. We’ve carved our data center into four logical ‘mini-firewalls’ enterprise, core, billing, and WAF—all on one box. Each has its own rules and logs, and any traffic between them still gets inspected. It’s like having multiple appliances without the extra hardware. Always-Up-to-Date Threat Feeds. Daily signature updates and AI-driven threat sensing mean we’re blocking the latest vulnerabilities almost as soon as they’re announced.

Secure internet access has reduced threats and simplifies firewall management for distributed teams

Threat detection needs improvement; Arista Edge Threat Management NG Firewall should follow Alto and Fortinet. One limitation that I've seen is AI-driven automation which needs to vastly improve. It has fewer third-party integrations, and therefore the adoption amongst very large enterprises is less; it's largely with the SMBs. Customer support can be improved. It's a smaller global footprint that Arista provides, with fewer certified partners in some regions and limited 24/7 support for premium vendors. I've categorically mentioned that it has sophisticated threat detection capabilities but they can be bettered. AI-driven automation can be improved, and therefore, I think the adoption with large enterprises can be much better. I think the current AI capabilities of Arista Edge Threat Management NG Firewall are a bit limited compared to other vendors. It primarily relies on threat intelligence feeds, signature-based detection, and reputation services. Currently, I would rate its AI capabilities as probably a seven out of ten because it does not provide for extensive GenAI or advanced ML-driven autonomous capabilities like some of its competitors. Threat intelligence aspects can be further improved, and I think there's a lot that the product can do with respect to the usage of AI. AI-driven automation and threat detection can vastly improve. I don't think they were purchased through AWS Marketplace. The adoption has to increase amongst large customers, and threat intelligence needs to improve for many customers to adopt, enhancing the security ecosystem that is relatively small.

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.

Quotes from Members

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

Pros

"These features have proven effective in protecting our network, handling large volumes of traffic smoothly without any issues."

"We've found the solution to be pretty stable."

"Fortinet has a product that can cater to any area of the security market."

"The security for endpoints is the most valuable. It is very secure for our workers. It allows us to secure a transaction and enable security for a specific segment in the workflow."

"The web tutor and automatic rules by schedule are good features."

"The overall features of Fortinet FortiGate SWG are good."

"Fortinet FortiGate has positively impacted our organization by strengthening our security posture, improving visibility into network traffic, simplifying security management, and providing reliable connectivity for both users and the branch office."

"It can expand easily."

More Fortinet FortiGate pros

"The product's initial setup phase is easy."

"Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks."

"I would say that if you're a small and medium enterprise or an education institution and you have a distributed organization looking for a cost-effective and easy-to-manage next-generation firewall solution with fairly good security, VPN, filtering, and centralized management, then Arista Edge Threat Management NG Firewall is an excellent choice."

"Phish Blocker is a valuable feature."

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

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

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

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

"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."

"The solution has high availability."

"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."

"URL blocking, Wireguard, Tail Scale, Engine Blocker, and VPN are the most valuable features for me."

More OPNsense pros

Cons

"I would prefer to have more detailed logs within the FortiGate products themselves rather than relying on a separate tool."

"Some of the software stability could improve."

"It's my understanding that more of the current generation features could be brought in. There could be more integration with EDRs, for example."

"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."

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

"FortiGate is really good. We have been using it for quite some time. Initially, when we started off, we had around 70 plus devices of FortiGate, but then Check Point and Palo Alto took over the place. From the product perspective, there are no issues, but from the account perspective, we have had issues. Fortinet's presence in our company is very less. I don't see any Fortinet account managers talking to us, and that presence has diluted in the last two and a half or three years. We have close to 1,500 firewalls. Out of these, 60% of firewalls are from Palo Alto, and a few firewalls are from Check Point. FortiGate firewalls are very less now. It is not because of the product; it is because of the relationship. I don't think they had a good relationship with us, and there was some kind of disconnect for a very long time. The relationship between their accounts team and my leadership team seems to be the reason for phasing out FortiGate."

"I am afraid I cannot say that I have seen a return on investment."

"I wish Fortinet FortiGate's UI updates would be done in a more simplified way to improve it."

More Fortinet FortiGate cons

"The product has a lot to improve in the area of policy implementation."

"The documentation is not clear."

"Threat detection needs improvement; Arista Edge Threat Management NG Firewall should follow Alto and Fortinet."

"Arista Edge Threat Management NG Firewall can be improved, particularly the user interface, which is not very good, and also the logs, which are not very good."

"OPNsense can be improved by making it more user-friendly, as its current UI is not that user-friendly when compared to paid software such as Sophos."

"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 ability to set the VPN IP address would be a welcome addition."

"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."

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

"To use Intrusion detection and Antivirus Plugin it is necessary to configure proxy; without a proxy, you cannot use the ClamAV antivirus plugin."

"pfSense has better performance and quicker updates."

"The support service isn't very accessible, so you have to look at the forums to solve some issues."

More OPNsense cons

Pricing and Cost Advice

"The price is okay, so far so good."

"Fortinet prices are around $600 for the small 40F model, and for licenses, the simplest option is about $300 for a year. They sell licenses that can last for 1, 2, 3, or 5 years."

"It is a cost-effective solution that meets the user's needs."

"It was worth the money overall. It's good value."

"The product is expensive. I rate its pricing a six out of ten."

"The licensing cost is at the intermediate level."

"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."

"Work through partners for the best pricing."

More Fortinet FortiGate pricing and cost advice

"The tool is quite cheap."

"I consider it an averagely-priced 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."

"It is free."

"It's 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."

"It is open source and free."

"I would rate the pricing three out of ten."

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

"It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident."
