Quick Setup (< 1 hour)

You can use OpenText TDR to monitor user and device behavior across your organization and automatically flag unusual activity that could indicate insider threats, credential misuse, or advanced attacks. It builds behavioral baselines for every user and entity without manual rule-writing, integrates with Microsoft Defender for Endpoint and Entra ID, and scores alerts by risk level so your SOC team focuses on real threats. It reduces false positives by up to 90% and maps detections to MITRE ATT&CK for faster investigation.
