What is a SOC (Security Operations Centre)?

A Security Operations Centre (SOC) is a centralized facility where cybersecurity professionals monitor, detect, analyze, and respond to security incidents 24/7. For Australian businesses, SOCs provide enterprise-level security monitoring and incident response capabilities without the cost of building internal teams.
