Supports secure remote authentication and provides comprehensive user activity tracking
The most important feature is the security capability because it provides a substantial amount of security for admin-related activities. Fortinet FortiAuthenticator can be used from anywhere in the world, and the authenticator services function globally. This global accessibility is one of the critical advantages, particularly since admin features are critical and security is a real concern. With Fortinet FortiAuthenticator, secure usage of firewall services and related functions is achieved. A complete log of all users who access the authenticator setup is maintained. Monthly logs are reviewed to check for any unnoticed activities. Each authenticated user's complete activity history is recorded. This logging capability allows for providing access to more admin users while ensuring security is not compromised and all users can be monitored.

Offers robustness and ease of use
The product improves our organization's daily healthcare tasks since the use of the tool reduces a lot of support calls, and its users remember many passports that keep on changing. Writing down the passwords somewhere would compromise the security of the system. In our company, the product streamlines access to critical applications and makes it more secure. The management of the system becomes easy with the product. With the product, you can also decide on the strength of the policy you need for your environment. It also helps in the area of authentication credentials. With the product in place, users need to remember fewer passwords, which makes an organization's environment much more secure. The product has improved productivity in the sense that users are now able to manage the tool on their own without having to wait for IT support. IT teams also have to handle fewer support calls and can focus on more value addition in other areas. I recommend the product to others who plan to use it. I suggest that it is always better to use the product's SSO capabilities since it provides security. With SSO capabilities, if you can use multi-factor authentication, you can add a second layer of security to make your system safer and free from attacks. The product's integration capabilities with existing healthcare infrastructure are good. The secure access provided by the product has helped all the applications in our company where security is required. I rate the tool a nine out of ten.
