ROI

Sentiment score
6.3
Fortinet FortiOS offers cost-effective, scalable security, with competitive pricing and partnerships, enhancing ROI compared to top brands.
Sentiment score
5.9
Netgate pfSense provides significant ROI with cost-effectiveness, eliminating license fees, ideal for small to mid-sized companies replacing costly systems.
Once it is deployed, I do not have to revisit or replace the hardware.
Network Administrator at a educational organization with 501-1,000 employees
The pricing of FortiOS is competitive and reasonable compared to other leading products such as Palo Alto and Check Point.
Senior Manager at ITX360 (Pvt) Ltd
Fortinet is strong in terms of cost and compatibility with other vendors.
Technology Consultant at 1ware
In four years of using it, that payment of 189 dollars per year has already paid off.
L2 Systems Administrator at a comms service provider with 201-500 employees
It's very favorable to have the inclusion of firewall, VPN, and router functionalities.
Owner at SimpleIT
The total cost of ownership is extremely low when you compare it to a lot of the other devices or other gateway appliances that are available on the market.
Operations Manager at a tech services company with 11-50 employees
 

Customer Service

Sentiment score
8.2
Fortinet FortiOS support is responsive and helpful but sometimes slow with complex issues, lacking top-tier vendor standards.
Sentiment score
7.8
Netgate pfSense receives praise for effective support, though some users experience slow responses; forums often suffice for troubleshooting.
I would rate them nine or ten out of ten.
Technology Consultant at 1ware
Fortinet technical support is very responsive and helpful.
Senior Manager at ITX360 (Pvt) Ltd
Support engineers sometimes lack eagerness to assist with issues such as the memory problem.
Director, IT Infrastructure Department at Zemen Bank S.C.
I couldn't imagine having better support.
Director of IT at Cutting Edge Hair Salon RSS
The biggest fear I have, and probably the only reason I still have the old one lying around is that if something were to happen to this hardware and I had to send it back for support, I need to be able to keep my network running in the meantime.
Co-Owner at Steffi and Tim
The support is knowledgeable and responds quickly, so the questions are addressed professionally and accurately.
Senior Project Engineer at a manufacturing company with 1-10 employees
 

Scalability Issues

Sentiment score
8.2
Fortinet FortiOS is highly scalable, adapting to different organizations, supporting growth and global deployments, yet may need hardware upgrades.
Sentiment score
6.6
Netgate pfSense is highly scalable for SMBs, supporting high user counts and complex configurations depending on hardware choices.
When customers' networks grow and needs expand, we can easily switch between models to trade up devices.
Technology Consultant at 1ware
It allows for the expansion of users and devices without additional licensing costs.
Senior Manager at ITX360 (Pvt) Ltd
We have been using Fortinet for bandwidth shaping and many other bandwidth-related functions.
Associate Director IT Operations at Procento
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.
CTO at Vigon Business Solutions Limited
I don't think Netgate pfSense can offer much scalability for big enterprises.
Director at a tech vendor with 5,001-10,000 employees
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.
IT Manager at a healthcare company with 11-50 employees
 

Stability Issues

Sentiment score
7.8
Fortinet FortiOS is praised for stability, with minor issues usually tied to configurations or external factors, not the system.
Sentiment score
7.1
Netgate pfSense is highly stable, with users attributing minimal issues to hardware rather than the firewall, ensuring reliable performance.
While the product is largely stable, it sometimes faces memory issues in specific versions like 11 OE, which can be disruptive.
Director, IT Infrastructure Department at Zemen Bank S.C.
There were no lags, there were no issues, and no hanging of the firewall.
Associate Director IT Operations at Procento
Stability is a seven out of ten because during version migrations, and sometimes with new versions, Fortinet is not as good.
Technology Consultant at 1ware
I rate the solution's stability a ten out of ten.
Infrastructure and integration Architect at CommunityForce
I've noticed a substantial improvement in stability and ease of use for upgrades and patching over the past year or two.
Technical Sales Specialist at a tech vendor with 10,001+ employees
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.
Partner and Owner at Free Range Geeks
 

Room For Improvement

Fortinet FortiOS requires improvements in VPN, pricing, compatibility, UI, security features, support, updates, deployment, and pricing consistency.
Netgate pfSense requires better centralized management, an updated user interface, improved security integrations, and enhanced documentation for ease of use.
Fortinet FortiOS faces memory issues, which can lead to unexpected downtimes.
Director, IT Infrastructure Department at Zemen Bank S.C.
There should be more documentation on how to use the CLI or how to perform CLI versions of tasks that can be done through the GUI.
Network Administrator at a educational organization with 501-1,000 employees
Compared to other market leaders like Palo Alto and Check Point, FortiOS has many bugs in its initial releases.
Senior Manager at ITX360 (Pvt) Ltd
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.
Information Security Manager at a tech services company with 11-50 employees
They should support the idea of configuration management as code from source code and provide a more robust API for managing the pfSense configuration.
Co-Owner at Steffi and Tim
Monitoring is crucial. The easier the monitoring and user interface, the simpler our team can work on and investigate issues.
Infrastructure and integration Architect at CommunityForce

Senior Manager at ITX360 (Pvt) Ltd
It also offers a free community version that can't be beaten.
Owner at Shaffer Consulting
Since I'm using my own hardware instead of a Netgate appliance, this is the most bang for your buck you can deploy.
Owner at a consultancy with 1-10 employees
There are cheaper firewall options, but they aren't as reliable and easy to manage.
Managing Director at IPC Solutions Pty Ltd

The solution offers good threat intelligence, which is crucial for our customers' security purposes.

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.
Information Security Manager at a tech services company with 11-50 employees
The most valuable feature is the routing capability.
Managing Director at a tech services company with 11-50 employees
It is not licensed and is not run by some corporation that watches you.

Featured Reviews

MS
Associate Director IT Operations at Procento
Single-pane management has simplified firewall control and has improved risk mitigation
I would not say that Fortinet FortiOS is not very scalable. Generally, what happens is that for enterprises, we hire consultants who do the capacity planning and sizing to determine what kind of firewalls to put in place. At the same time, it is not only the number of users; it also depends on the number of WAN links coming in and everything, because we have been using Fortinet for bandwidth shaping and many other bandwidth-related functions. They should improve their machine learning AI capabilities of Fortinet FortiOS because there is too much competition. Other players are also improving and making a lot of changes in their UI and overall operating system.

Principal Cloud Architect - Software Engineer at a consultancy with 11-50 employees
Rapid VPN setup has connected offices in minutes and brings live insights for proactive issue control
What I appreciate the most about Netgate pfSense is the ease and straightforward nature of the platform. I can set up a new office in less than 10 minutes. The benefits of using Netgate pfSense are that I can set up VPNs in less than two to three minutes, and then just deploy the file across my networks, where everybody would be connected in less than an hour. The dashboards of Netgate pfSense bring all the necessary information that I need at a glance, and it is actually a live update every three to five seconds. It is spotless, and I have been able to catch issues before they hit operations.
