On one side, defender AIs like CrowdStrike Charlotte AI, Microsoft Security Copilot, SentinelOne Purple AI, Palo Alto Precision AI, Darktrace, and Vectra AI automate the SOC. On the other side, WormGPT, FraudGPT, AI voice-clone phishing, polymorphic malware, and prompt injection accelerate attacks. This deep dive walks through EDR/XDR/SIEM, NDR, ITDR, code security, cloud CNAPP, AI threat intel, OWASP LLM Top 10, NIST AI RMF, the Korean and Japanese vendor landscape, and how SOC analyst careers shift in 2026.
