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.

KL
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.

Supervisor, Client Security at a consultancy with 11-50 employees
World-class support and highly effective for application control and elevation
Their product is solid. I have a hard time complaining much about it because when we do find little things, they are usually interface-related or related to things that would be nice to have. Their idea portal, unlike so many other vendors we deal with, shows movement. At least four to eight features of ThreatLocker exist because I made a request in the last five years, and it became a feature of the actual product. When it comes to improvements, we moved the product as customers, and we got to move the product by making suggestions. They seem to be very reactive to it, so there is not a whole lot that they actively need to change right now. It is one of those situations where when we run into something that would be nice to have, it happens. They make it work.
