Security Information and Event Management (SIEM) collects logs from firewalls, servers, cloud apps, and endpoints, then correlates events to detect suspicious patterns — failed logins, privilege changes, or data exfiltration. For regulated Canadian organizations, SIEM supports audit trails required by PIPEDA breach investigations and industry frameworks. Managed SIEM (SOC) services filter noise so your team sees actionable alerts instead of thousands of daily emails. SIEM success depends on log coverage: if a system does not forward events, blind spots remain. Start with identity, email, and perimeter logs, then expand as maturity grows.
