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.
Neha Chhangani - PeerSpot reviewer
Business Analyst at a startup based organization
Centralized identity governance has automated lifecycle management and simplifies compliance
One Identity Manager could be improved by making the initial setup and configuration simpler, especially for complex workflows and integrations. The user interface and reporting dashboards could also be more modern and intuitive with better out-of-the-box analytics. Additionally, clearer documentation and faster implementation guidance would help organizations get value more quickly. One specific challenge my team encountered was the complexity during initial configuration, especially when setting up custom workflows and role models which required more time and expertise. We also felt that out-of-the-box reports and dashboards are limited, and more customizable real-time analytics would be helpful. Better documentation and guided setup wizards would make adoption easier, particularly for teams new to identity governance tools. One improvement I think One Identity Manager needs is the enhanced self-service experience. The end-user self-service portal could be more intuitive with clearer guidance for access requests and password resets. Additionally, while integrations are solid, deeper cloud-native connectors and API-driven automation would help in hybrid and multi-cloud environments. A more responsive mobile interface or dedicated app for approvals and tasks would help managers who are often on the go. One more improvement is the built-in predictive insights or trend dashboards around access patterns and risk could improve proactive governance. More descriptive error messages and in-tool troubleshooting tips during setup configuration would reduce dependency on external documentation or support.
