Room For Improvement

Fortinet FortiAuthenticator struggles with integration, complex setup, limited customization, high pricing, and needs better support and documentation.
OneLogin requires simplified setup, better support, enhanced integration, customization options, improved interfaces, and flexible pricing for optimal usability.
For example, authentication for wireless users expires after 24 hours, requiring re-authentication daily.
Head of computer systems at Indian Institute of Space Science & Technology(IIST)
For example, Cisco Duo is on the cloud, so we cannot compete with that part if a user requires a cloud-based two-factor authentication solution.

I recommend Fortinet make its images migratable between environments.
Senior Network and Security Engineer at Symbol Technologies PLC
More real-time alerts, such as when access fails or MFA is triggered, would help users understand issues faster.

Step-by-step tutorials and troubleshooting guides would help users resolve issues faster without needing to contact support.

The two major pain points are customer support needing improvement and the integration with third-party software needing to be more flexible.

Featured Reviews

Sachin Vinay - PeerSpot reviewer
Assistant Manager-Networks at a university with 1,001-5,000 employees
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.
Amit Rathod - PeerSpot reviewer
Senior Analyst - IDAM at Toll Holdings Limited
Unified sign-in has simplified access control and has supported end-to-end identity lifecycle
The authentication process is good, but sometimes the responsiveness to requests for enhancement is very slow. I sometimes face issues with platform stability, flexibility in configuration, and limited API availability. I experience downtimes two to three times per year. OneLogin's support team is sometimes very slow to respond. There is a feature limitation with mapping, as OneLogin does not provide one-to-all mapping. For client deployment, we need to create separate mappings for each request, and we cannot use the same mapping for multiple requests. Other areas that have room for improvement are related to API limitations. If a client requires more APIs, such as 5,000 or 6,000, OneLogin charges more. The API rate limits by default or the standard limit should provide more than 5,000. Additionally, OneLogin could provide more flexibility in configuration. These are the main limitations I have identified with OneLogin.
