Review summaries and opinions

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

ROI

Sentiment score
5.7
Fortinet FortiGate offers cost-effective security with quick deployment, improving efficiency, reducing downtime, and providing a strong return on investment.
Sentiment score
6.5
Netgate pfSense provides cost-effective network management with inexpensive hardware, eliminating costly licenses, and offering reliable, low-maintenance features.
Sentiment score
4.4
OPNsense offers quick ROI, annual savings, improved network protection, efficiency, but faces challenges like market disruptions and cyber threats.
Clients are now comfortable and not wasting productive hours on IT support.
The automation part is giving us a cost benefit and speed; we can react faster.
It's a very useful tool to mitigate and protect your enterprise.
If they can save their data from attackers then it would save them at least two days of not working plus the cost of recovery, which would be much more than the cost of the system and maintenance.
Since the memory leak fixes, it's been incredibly stable and requires minimal maintenance.
In four years of using it, that payment of 189 dollars per year has already paid off.
The network attacks reduced by approximately 60% after using that, even without customizing the custom configuration yet.
For a very little investment, I was able to increase the security of my network.
 

Customer Service

Sentiment score
6.4
Fortinet FortiGate support is mostly praised for responsiveness and knowledge, though inconsistencies exist in complex cases or regions.
Sentiment score
7.9
pfSense users benefit from robust online resources and community support, with paid services praised for promptness and professionalism.
Sentiment score
5.0
Users often solve issues using online resources, valuing community help, but suggest OPNsense centralize and improve support options.
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.
When I provide detailed information about the problem, they've been able to reply quickly with a solution or go research the problem and get back to us quickly with a fix.
They are highly responsive.
I couldn't imagine having better support.
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.
OPNsense is open source, so you have to rely on the community for customer support.
 

Scalability Issues

Sentiment score
7.0
Fortinet FortiGate offers scalability and easy integration for diverse environments, catering to businesses from small to large enterprises.
Sentiment score
6.6
Netgate pfSense is highly scalable and adaptable, efficiently managing network demands and supporting seamless expansion across various environments.
Sentiment score
7.4
OPNsense is scalable and adaptable, supporting small to large deployments with flexibility in hardware upgrades and virtual machines.
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.
If I put things into a certain context and say that we have a network that has around 100 people, then you don't put up a device that can manage 100 people. Instead, you need to get a device that can manage 150 to 200 people, and then you can create room for growth.
I don't think Netgate pfSense can offer much scalability for big enterprises.
Even with a jump from a 50 megabit to a 500 megabit internet connection and approximately 65 active VPN clients, our firewall operates smoothly without any strain.
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.
 

Stability Issues

Sentiment score
7.5
Fortinet FortiGate is highly stable and reliable, excelling in continuous operation with effective network management, despite occasional update issues.
Sentiment score
6.5
Netgate pfSense is highly reliable and stable, often rated top-tier, with most issues stemming from non-software factors.
Sentiment score
8.6
Users find OPNsense generally stable, though VPNs, updates, and hardware compatibility can occasionally cause issues.
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.
I rate the solution's stability a ten out of ten.
I've noticed a substantial improvement in stability and ease of use for upgrades and patching over the past year or two.
When I replace consumer routers with pfSense for small businesses with two or three employees, they are often amazed to discover the router can run for a year without a reboot.
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.
 

Room For Improvement

Users express concern over Fortinet FortiGate's interface stability, functionality, performance issues, and call for improved support and features.
Netgate pfSense needs enhancements in reporting, security features, user interface, compatibility, documentation, and integration with third-party tools.
OPNsense's challenges include interface usability, integration issues, and the need for improved VPN, analytics, and virtualization support.
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.
There is some trade-off between having a certain level of security and maintaining acceptable performance.
If I need to go between different VLANs, I have VLAN 19.1 and VLAN 19.2, and I strictly use Netgate pfSense, but it doesn't route very efficiently and works quite slowly.
They should support the idea of configuration management as code from source code and provide a more robust API for managing the pfSense configuration.
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.
 

Setup Cost

Fortinet FortiGate offers high initial costs but competitive pricing, valued features, and flexible licensing compared to competitors.
Netgate pfSense is a cost-effective, flexible firewall solution offering free software and optional paid support for enterprises.
OPNsense is a cost-effective, open-source firewall solution with free core features, ideal for budget-conscious enterprises.
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.
The price of setup is approximately €500 to €800, which also includes the initial monitoring.
You can acquire a decent embedded PC for around a hundred dollars and install pfSense on it, effectively creating a robust firewall solution.
The product is free of cost.
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.
 

Valuable Features

Fortinet FortiGate offers robust, affordable security with user-friendly interface, centralized management, and efficient SD-WAN capabilities.
Netgate pfSense is favored for its open-source flexibility, robust features, affordability, and strong community support for diverse networking.
OPNsense is appreciated for its flexibility, user-friendly interface, robust security features, and extensive customization options through open-source access.
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.
We have multiple VLANs, and with assistance, it was easy to get everything set up and running in our organization the way we needed it to.
We had downtime before pfSense. We've never gone down using the solution.
It is very stable, and it works very well.
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.

Vasu Gala - PeerSpot reviewer
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.
Jean-Pierre DAREYS - PeerSpot reviewer
Easy to use, configurable, flexible, excellent user group support
I'm not knowledgeable enough to suggest new features. The use has been very straightforward. Whatever questions I've had, I've found videos to help me on YouTube, or I've been able to ask the forums. I've also reached out to technical support and I've received help although there could be more videos or tutorials from Netgate, in addition to third parties who have already implemented it, which is great. I have suffered a lot of problems over time but I don't think the problems are related to the hardware or the software. I am convinced that the problems have been related to hacking during configuration. During the setup process, while experimenting, the device would stop working or the password would suddenly not allow access, requiring re-installation and re-configuration, it was very slow going until I moved to the cloud. The dashboard is a little bit slow and the reporting isn't always current or immediate but acceptable. I'm not sure I can make data-driven decisions due to insufficient volume. I would need enhanced reporting, statistics, playback. I haven't looked at the reports a lot since because you have to access the log files, time is an issue, I use it in a home office environment.
Moutaz Sheikh Alard - PeerSpot reviewer
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.
