The cybersecurity landscape has evolved dramatically, with organizations facing increasingly sophisticated threats that require advanced detection, analysis, and response capabilities. Modern security operations centers (SOCs) rely on a complex ecosystem of tools and platforms to protect against cyber threats.
Three categories of security platforms have emerged as essential components of modern cybersecurity architectures: Security Information and Event Management (SIEM), Security Orchestration, Automation, and Response (SOAR), and Extended Detection and Response (XDR). Each serves distinct but complementary roles in comprehensive security programs.
Security Information and Event Management (SIEM)
SIEM platforms serve as the central nervous system of security operations, collecting, correlating, and analyzing security events from across the enterprise infrastructure to identify potential threats and compliance violations.
