AI is transforming cloud security by enabling faster, more accurate threat detection and response. Cloud workload protection platforms like Wiz and Lacework leverage machine learning to baseline normal behavior and surface anomalies in real time. AI‑driven UEBA identifies suspicious user activity across AWS, Azure, and GCP, such as unusual data access patterns or privilege escalation. Automated playbooks powered by SOAR orchestrate incident response, isolating compromised resources and rolling back risky configuration changes. Generative AI also assists analysts by summarizing alerts, enriching incident tickets, and suggesting remediation steps, dramatically reducing mean time to respond (MTTR). As cloud footprints grow, AI‑infused security operations become essential for maintaining resilience and compliance.
