Datadog Synthetic Monitoring now supports Microsoft Active Directory with Kerberos single sign-on, enhancing its ability to proactively detect authentication failures that might disrupt employee access to critical applications and APIs. This integration allows for automated tests to be run from within a network's Active Directory domain, ensuring reliable authentication and minimizing operational risks. By continuously validating Kerberos-authenticated login workflows and API endpoints, Datadog Synthetics helps maintain productivity and reduces authentication-related outages. It also offers a unified monitoring approach across internal and external applications, improving the correlation of authentication failures with system metrics like latency and network performance. This new feature aims to close visibility gaps by providing a single source of truth for application performance, allowing early detection and swift resolution of potential authentication issues before they impact employees.
