What is a SOC (Security Operations Centre)?

Security Operations Centre Guide for Australian Businesses

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.

SOC Technology Integration

Modern SOCs integrate multiple security technologies for comprehensive protection. Learn about SIEM platforms for log analysis, EDR solutions for endpoint monitoring, and SOAR platforms for automated response capabilities.
