Most of our clients are using the free version rather than the paid version due to the high range of maximum users available for the free version.

I hope Fortinet will start an insider developer program where professionals can provide feedback on new releases to ensure improvements.
Head IT at Burraq Cyber Security Solutions
It's not very easy to expand, and it would be beneficial if the process were simpler.
Chief Cloud Architect at a tech vendor with 10,001+ employees
It does not utilize much memory or CPU on the VM.

I would give OpenVPN a six out of ten for scalability, as it's usually a single user or single device.

Senior Technical Manager at Flexaccel
Remote access has become seamless and secure while deployment remains simple for our users
Performance could be improved today. People are now moving toward SASE, which stands for Secure Access, Secure Edge Solution. Fortinet also has that offering, which would be easier since it operates through the cloud, acting as a first line of defense. When the user connects to the internet, they connect to the cloud first for posture assessment and monitoring before connecting to the outside world. The impact is significant because nowadays people are adopting SASE. During COVID time, many users were trying to connect back to their office, causing the performance or CPU utilization of the firewall to increase tremendously, which slowed down performance. I have not worked with endpoint telemetry in Fortinet FortiClient that could have been helpful for threat mitigation.
Girraj Godia - PeerSpot reviewer
Devops Engineer at Emergent
Has improved internal app access by allowing secure user onboarding and simplified network whitelisting
The plan for OpenVPN Access Server could be improved. When adding new people, better plans for startups would be beneficial. I'm working in a startup and sometimes people think we should take the enterprise plan or not. If there was a dedicated plan for startups, it would be really helpful. For instance, providing store credit for OpenVPN Access Server through a startup program, similar to YC's program which gives credit to new startups. UI-wise, OpenVPN Access Server is easy to manage, but the overall overview dashboard in the admin portal could be improved. Currently, you have to go through dropdowns to find where to add users or whitelist IPs. Creating an onboarding dashboard where an admin person can find these things easily would be beneficial.
