SIEM by TEHTRIS is a Security Information and Event Management solution integrated within the TEHTRIS XDR AI Platform. SIEM collects, archives, correlates, and alerts on security events 24/7. It monitors infrastructure continuously, automating the processing of information from infrastructure logs. SIEM combines security information management (SIM) and security event management (SEM), including an enhanced SIM subsystem for collecting events, normalizing data, and retaining it in secure storage. The advanced SEM subsystem acts as the brain, with an intelligence layer to sort data, select relevant information, and aggregate events to detect complex attacks. SIEM gathers and retains data for months, enabling Digital Forensic or Incident Response operations.
