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
7.5
Fortinet FortiGate is valued for affordability, cost savings, enhanced security, operational efficiency, quick implementation, and long-term ROI benefits.
Sentiment score
7.9
Netgate pfSense offers cost-effective, high-performance solutions, replacing pricier options and improving network stability, efficiency, and security.
Sentiment score
2.5
Entities benefited from rapid returns and cost savings with OPNsense, offering superior threat management compared to Check Point and FortiNet.
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.
 

Customer Service

Sentiment score
7.0
Fortinet FortiGate's customer service varies, with praise for responsiveness but criticism for slow, sometimes inadequate technical support.
Sentiment score
8.0
Netgate pfSense offers reliable community resources and praised paid support, despite occasional inconsistencies with complex technical issues.
Sentiment score
6.4
Many users rely on forums for support, expressing mixed satisfaction with OPNsense's accessibility, cost, and technical support.
I would rate their support for FortiGate a nine out of ten.
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.
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.
I mainly rely on community support since the solution is open source.
 

Scalability Issues

Sentiment score
7.3
Fortinet FortiGate scales well for diverse enterprises, though planning and licensing are crucial to avoid hardware limitations.
Sentiment score
7.0
Netgate pfSense is scalable and cost-effective, managing large networks efficiently with adaptable hardware and seamless expansion capabilities.
Sentiment score
6.5
OPNsense is scalable for diverse organizations, efficiently supporting different user volumes, with some challenges in high-volume voice traffic.
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.
In my organization, there are 400 users, and OPNsense serves as our gateway and proxy for all of them.
Aside from these aspects, it demonstrated good scalability.
It supports routing, VPN setups, and traffic monitoring with additional packages like Snort and Suricata.
 

Stability Issues

Sentiment score
7.9
Fortinet FortiGate is generally stable and reliable, with minor issues arising from new features, firmware updates, or hardware constraints.
Sentiment score
6.9
Users highly rate Netgate pfSense's stability, attributing rare issues mainly to hardware rather than the software itself.
Sentiment score
8.5
OPNsense is stable with high ratings, despite issues with VPN failover, occasional bugs, and hardware compatibility concerns.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
We have not had any problems with the operating systems or maintenance of subscriptions.
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.
Stability-wise, I rate the solution a ten out of ten.
It just doesn't respond, so I have to restart it over and over again to try to figure out what the problem is.
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.
 

Room For Improvement

Fortinet FortiGate needs enhancements in firmware, usability, integration, support, reporting, VPN, cloud integration, and documentation for seamless use.
Netgate pfSense needs better GUI usability, management, consistent updates, improved performance, intuitive interfaces, and strategic communication.
OPNsense faces challenges with integration, user interface, documentation, scalability, performance, and security features, needing enhancements in various areas.
By providing an integrated solution, users would have access to all features and functionalities within a single window, eliminating the need to navigate through multiple windows.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
The constant daily revisions necessitate meticulous identification of the relevant documents to prevent the use of outdated information that could jeopardize our environment.
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.
The user experience when we create policies can be made easier.
Some of the features include classified traffic and better blocking of newly registered DNS domains.
 

Setup Cost

Fortinet FortiGate offers competitive pricing with upfront affordability, simple licensing, and long-term value, despite potentially high renewal costs.
Netgate pfSense is cost-effective, open-source, integrates key functions, and offers affordable subscriptions, appealing to budget-focused enterprises.
OPNsense is a cost-effective, flexible solution for enterprises, preferred over costly alternatives like FortiGate and Palo Alto.
The most expensive part is the renewal of the license subscription.
FortiGate is priced lower than Palo Alto.
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.
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's a free solution.
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.
 

Valuable Features

Fortinet FortiGate delivers robust security features and intuitive management, offering scalable and affordable network protection solutions.
Netgate pfSense is praised for its performance, flexibility, robust features, and user-friendly interface, enhancing security and scalability.
OPNsense is valued for its flexibility, user-friendly interface, robust features, frequent updates, and compatibility with useful plugins.
The firewall, IPS, and VPN functions are the most valuable features.
FortiGate provides solid protection against viruses, malware, and other threats.
In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable.
With pfSense, network configurations adhere to standard practices, facilitating troubleshooting without the need for complex overlays or policies.
The price point is the most valuable aspect of the solution.
I like the tool's flexibility in the sense that you do not have to buy an appliance. You can put it on your own hardware, and it can be very simplistic hardware with simple configurations.
The most valuable features include the basic firewall functionality and the GeoIP location services.
One of the most valuable features is the network checking.
OPNsense is easy to use and open source.

Jorge Martínez - PeerSpot reviewer
Offers good SD-WAN capabilities and integrates easily with Fortinet devices
I am not part of the initial setup or deployment process since I work in presales. The setup or deployment is quite easy, as you can do a one-touch deployment that automatically connects to the FortiManager cloud when you connect it to a broadband or dynamic IP, allowing you to start the configuration from that point. We usually sell it for on-premises setups. It's on the cloud only when the client has virtual machines or their own service. Sometimes they have a service on the cloud like AWS, but it's more difficult to sell now because AWS has an e-commerce option where you can buy FortiGate directly. The only thing you need is someone to manage and configure.
Vincent Hamm - PeerSpot reviewer
I appreciate the depth of what the solution can do and the simplicity of the initial setup
We do a lot of managed services and are currently trying to get people off of L2TP VPN. Apparently, we can download a mobile config file from a configured NetGate device, and we're primarily Apple. We've experimented with it on a device that's not a production device, and we can't seem to get the phase one IPSec set correctly so that the Apple config will accept it. We've tried looking at the documentation but haven't found anything. While it's not the highest priority, it is rather frustrating. We'd like to do this, and the feature is right there, but we can't get it configured. We certainly don't want to try it on a production machine because it will break the current VPN. I would like to download the Apple mobile config so that I can tell it to configure my VPN connection to do that. We have some cross-platform things. So there's also a Windows VPN. You can download a script or a PowerShell, put it on a Windows machine, and it can connect to the VPN. It would be nice if I could say I want Mac only, Windows only, or both. I wish it could configure the IPSec phase one and phase two, or at least give me solid instructions on how to configure that. It doesn't supply out-of-the-box visibility to drive decisions. You get 75 log lines, so if you're trying to troubleshoot something, you have to look at one log and then another. It integrates with SysLog systems, but our customers are not at the level where they want to pay for some third-party SysLog system. Usually, we can get things taken care of fairly quickly. I would like to have the ability to control all my devices from one place. With Ubiquiti, you can get a controller that allows you to control all of your Wi-Fi devices, switches, and routers. From one area, you can switch to that customer and see what's happening in their environment. That's not part of pfSense. I understand why it's not because pfSense is open source and community supported. That's something that someone in the community needs to pick up and run with. It's not something the pfSense can easily implement. If they could, that'd be great.
Akram Zaki Hussein - PeerSpot reviewer
Robust network security and management offering a user-friendly interface, open-source flexibility, and cost-effectiveness, with challenges regarding initial setup and the absence of official support
The interface is user-friendly, but there's room for improvement in terms of intuitiveness. The bundle management aspect requires additional attention to make it more intuitive, especially for inspecting high-level traffic. This is crucial, especially for larger companies where the existing features might not be the most optimal choice, given limitations like printer constraints. For high availability, it's crucial to have a method in place where a designated component oversees the entire process. Given that OPNsense plays a pivotal role as a firewall, safeguarding against various threats, having a reliable backup ensures uninterrupted protection even if unforeseen events impact the primary virtual machine. It would be beneficial if OPNsense supported additional virtualization platforms like Hyper-V from Microsoft and VMware, similar to how Kaspersky has integrated them.
