Google Cloud just dropped an autonomous security system built to match the speed of AI-driven attacks. The new Google AI Threat Defense platform fuses Gemini models, Wiz cloud mapping, CodeMender repair agents, and Mandiant threat expertise into one always-on loop. Attackers now weaponize AI to scan for flaws and chain exploits in minutes. Traditional human-led patching no longer keeps pace. Google responded with a four-step framework drawn from its own internal defenses: Prepare, Scan and Prioritize, Remediate, and Monitor. Google assembled the pieces over years of acquisitions and internal builds. Wiz, bought for $32 billion in March 2026, supplies live exposure maps across clouds, APIs, identities, and runtimes. It flags reachable assets and simulates attack paths with its Red Agent. Mandiant adds real-world incident response data and helps craft response plans for legacy systems or patch surges.…
