In 99% of cases, we do not have to do configurations on our own as they are normally handled by their service providers.
Director at a manufacturing company with 11-50 employees

Scalability Issues

Fortinet FortiClient is scalable, suitable for small to large enterprises, but reviews on ease of scaling are mixed.
Sentiment score
5.9
OpenVPN Access Server offers scalable performance but may face challenges with specific setups and licensing costs during large-scale expansion.
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.

Room For Improvement

Fortinet FortiClient needs improved management, simplicity, features, compatibility, pricing, connectivity, scalability, authentication, and better support across OS.
OpenVPN Access Server offers enhanced usability and security but faces challenges in connectivity, scalability, and interface design improvements.
FortiClient needs improvement in restricting user information and ensuring more secure customer data to better protect source code and reduce the risk of security breaches.
Head IT at Burraq Cyber Security Solutions
There are advanced features like Zero Trust that I currently do not use but could be beneficial for security.

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.
Network operation center engineer at a computer software company with 10,001+ employees
If they had a one-click setup where you provide credentials instead of manually running commands, that would be beneficial.

FortiClient is a value-for-money product and is not considered expensive compared to similar products on the market.
Global Head of IT Infrastructure at EPL Americas
Justifying the price to clients can be difficult.
Head IT at Burraq Cyber Security Solutions
FortiClient is included in a package with the UTM features, so there is no separate cost for it.
Senior Manager Tech Compliance at Qenta Inc.
The sticker price may look clear, but the real cost includes the time spent untangling subscription limitations, account conflicts, sales handoffs, and unclear guidance.
Webmaster & Software Engineer at a university with 501-1,000 employees
My experience with pricing is excellent as the pricing is free.

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.

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.
