Platform that collects and analyses security logs from across your IT environment to detect threats and support compliance.
Security Information and Event Management (SIEM) aggregates log data from firewalls, servers, applications, endpoints, and cloud services into a centralised platform. It correlates events across these sources to identify patterns indicating attacks—such as failed logins followed by successful access from an unusual location. SIEM provides real-time alerting, historical analysis for incident investigation, and compliance reporting. Modern SIEM platforms use machine learning to reduce false positives and identify subtle threats. For regulated industries, SIEM is often essential for meeting log retention and monitoring requirements.
Why It Matters
The DSC Perspective:
SIEM gives you the audit trail that compliance frameworks demand. ISO 27001, NIS2, and many customer questionnaires require centralised logging and monitoring. SIEM also dramatically speeds up incident investigation by putting all your security data in one place.
