Featured Reviews

Sebastian Micu - PeerSpot reviewer
Auth0 | Ciam Consultant at Intragen
Platform has strengthened user security, improved sign-on journeys, and supported future growth
Regarding areas for improvement, Auth0 Platform is a premium product, and its pricing reflects its enterprise-grade capabilities. While the cost can sometimes make smaller businesses hesitate, the return on investment usually outweighs the initial price tag when the platform is architected and implemented correctly. The comprehensive feature set, top-tier security, and reduced development time justify the investment for organizations prioritizing scalability. On the technical side, I would like to see Auth0 introduce more no-code branding options for Universal Login. Currently, achieving a highly specific, bespoke login experience often requires utilizing Liquid page templates or the newly released Advanced Customizations for Universal Login. While these are incredibly powerful tools, they do require some technical expertise to execute flawlessly. Having more robust, out-of-the-box customization options would be a great enhancement in the future.
Sachin Vinay - PeerSpot reviewer

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.
