For a very little investment, I was able to increase the security of my network.
The service generates a low rate of false positives, reducing the overhead of managing false positive events.
 

Customer Service

Sentiment score
6.6
Fortinet FortiGate support is generally effective, but some users report delays and issues with complex problem resolution and communication.
Sentiment score
4.9
Users often solve issues using online resources, valuing community help, but suggest OPNsense centralize and improve support options.
Sentiment score
7.0
Palo Alto Networks WildFire's support is responsive and expert but varies in availability and response time, especially for smaller companies.
They offer very accurate solutions.
The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with.
I would rate the technical support for Fortinet FortiGate a ten out of ten.
Compared to some open-source projects with weak support, OPNsense stands out for having both a strong community and commercial backing options.
I mainly rely on community support since the solution is open source.
If you say you do not have one, it is finished. This is where the monopoly starts.
There is a lack of SLA adherence, and third-party partners do not provide prompt responses.
The service response times are aligned with standards, responding within a few hours based on the problem's criticality.
The support is quite difficult to access promptly.
 

Scalability Issues

Sentiment score
7.1
Fortinet FortiGate efficiently scales for SMEs, though hardware upgrades can be challenging, with virtual deployments offering flexibility.
Sentiment score
6.6
OPNsense is scalable and adaptable, supporting small to large deployments with flexibility in hardware upgrades and virtual machines.
Sentiment score
8.2
Palo Alto Networks WildFire efficiently scales for diverse environments, supporting thousands of users while integrating well with security modules.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
Aside from these aspects, it demonstrated good scalability.
It supports routing, VPN setups, and traffic monitoring with additional packages like Snort and Suricata.
OPNsense is an extremely scalable solution.
Wildfire is highly scalable.
Palo Alto Networks WildFire is scalable, and I give it a nine for scalability.
 

Stability Issues

Sentiment score
7.7
Fortinet FortiGate is praised for its dependable stability, minimal downtime, and robust performance, especially with regular firmware updates.
Sentiment score
7.5
OPNsense is highly stable and reliable, excelling in security and usability, but occasionally faces VPN and update issues.
Sentiment score
8.5
Palo Alto Networks WildFire is highly rated for reliability, seamless integration, and effective network security performance without disruptions.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
Currently, we are experiencing a general outage of one of the main internet service providers of the Dominican Republic, and we have not been impacted in our operations because with SD-WAN, we have another internet service provider and we are working with the second WAN connection without any disruption.
For home and small network use, OPNsense is also reliable, providing enterprise-grade security at no cost.
OPNsense is the same, but it does have a way of installing the Realtek drivers, which gives you a lot more stability overall on the system.
The only challenge faced was its inadequacy to manage large voice traffic effectively, even with dedicated hardware.
It performs filtering, malware blocking, and scanning.
The solution is scalable and stable.
 

Room For Improvement

Users seek improvements in FortiGate's performance, web interface, reporting, documentation, licensing, and training resources.
OPNsense's challenges include interface usability, integration issues, and the need for improved VPN, analytics, and virtualization support.
WildFire needs improvements in integration, user-friendliness, and pricing, along with better support, automation, and global availability.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
While Fortinet claims to offer a comprehensive network solution, it falls short in addressing computer application issues, particularly server security.
When considering Sophos XG, which we also use, the logging and reporting functionality is notably more efficient.
For high availability, it's crucial to have a method in place where a designated component oversees the entire process.
Improved guidance on package usage and integration beyond relying on external tutorials or community support would be beneficial.
I would like the APIs to be more mature and more developed and have more options to automate threat hunting.
The dashboard should provide better visibility, especially in showing how many files are sent to Wildfire and their findings.
It is a very good product.
The support could be improved, as it takes a while to get assistance from the vendors.
 

Setup Cost

Fortinet FortiGate offers robust features at a competitive price but can be costly, especially with licenses; long-term pricing negotiation advised.
OPNsense is a cost-effective, open-source firewall solution offering affordability compared to commercial firewalls, appealing to enterprises.
Palo Alto WildFire offers advanced threat protection, appealing to enterprises despite its high cost, potentially deterring smaller organizations.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.
It offers cost savings as it is generally cheaper than the competition.
It is about 20% cheaper.
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.
I would rate the pricing a nine out of ten, especially considering the availability of a free community edition.
It is free.
I would rate it an eight out of ten in terms of affordability.
 

Valuable Features

Fortinet FortiGate provides robust security, seamless integration, user-friendly interface, and cost-effective advanced threat management for diverse network environments.
OPNsense is user-friendly and cost-effective, offering extensive VPN, firewall features, and easy scalability with strong community support.
Palo Alto Networks WildFire automates threat analysis, excels in sandboxing, and offers robust security with cloud-based, user-friendly features.
In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable.
FortiGate has helped reduce the risk of cyberattacks that might disrupt our client's production.
These features help reduce our downtime, manage the ISPs, and deploy SLAs for all the website traffic.
The most valuable features include the basic firewall functionality and the GeoIP location services.
I can have a Wi-Fi VLAN and feel secure that the server network or the VM network that I have on a different VLAN are isolated, and they cannot talk to one another, which adds a great level of security.
It offers enterprise-grade features such as intrusion detection and prevention system, VPN support, traffic shaping, and web filtering, all without license cost.
Integrating Palo Alto Networks WildFire with various security protocols similar to a firewall has significantly improved the overall threat detection capabilities in our organization.
The most valuable feature of Wildfire is its sandboxing capability for examining suspicious files or locations.

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 cybersecurity with advanced sandboxing and effective in controlling DNS issues
Improvements are needed in the UI part. The dashboard should provide better visibility, especially in showing how many files are sent to Wildfire and their findings. This information should be integrated with the Dashboard so that system admins can see what is happening. Furthermore, technical support needs a lot of improvement, particularly in terms of responsiveness and adhering to service level agreements.

Cisco ASA vs. Palo Alto Networks
Cisco ASA vs. Palo Alto: Management Goodies You often have comparisons of both firewalls concerning security components.
