Scalability Issues

Sentiment score
7.2
Fortinet FortiClient is scalable, suitable for small to large enterprises, but reviews on ease of scaling are mixed.

OpenVPN Access Server scales well but faces challenges with certain operating systems, regions, and licensing costs.
We normally take into consideration while installing the product that it can scale up to approximately 20%, but not more than that.
Director at a manufacturing company with 11-50 employees
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.
Senior Technical Manager at Flexaccel
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
When we deploy and install OpenVPN Access Server, the principle is to install and forget.
System Network Administrator at a consultancy with 201-500 employees
You can easily upgrade the underlying hardware resources or spin up additional nodes in a cluster configuration if you need to handle a massive surge in concurrent users.

It's not very easy to expand, and it would be beneficial if the process were simpler.

Additionally, native support for newer, lighter protocols like WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency would be beneficial.
Manager at a computer software company with 201-500 employees
With WireGuard, which is locked down over UDP, it is harder for attackers to probe ports.

The sticker price may look clear, but the real cost includes the time spent untangling subscription limitations, account conflicts, sales handoffs, and unclear guidance.

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.
AS
Network operation center engineer at a computer software company with 10,001+ employees
Secure remote access has protected critical data and now simplifies role-based user management
An area for improvement is the pricing model. The concurrent user licenses get expensive pretty quickly as your organization grows, so more flexible pricing options would be a huge plus. Another area is configurational disconnect. While the admin web UI handles about 90% of what you need, the moment you have to do deep, advanced routing customization, you still have to drop back to the command line interface to make those changes. It would be great to see those deeper configurations completely integrated into the web portal. Lastly, it would be awesome to see native support for newer, lighter protocols through WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency.
