Two 2025 shifts rewrite the IR playbook: GuardDuty Extended Threat Detection now emits a single critical attack-sequence finding instead of a pile of high findings, and AWS Security Incident Response moved to metered pricing (free first 10,000 findings/month, then $0.000676 each) on November 21, 2025. The lesson is to page humans on the top 1% of correlated criticals, isolate instead of terminate, and let auto-triage absorb the rest. Here are the runbooks.

After Security Hub Essentials consolidated Inspector and CSPM into per-resource pricing (example: 500 units ≈ $1,875/mo), most AWS-only estates should run native first. This guide scores when Wiz/Orca-class tools earn a line item—and when paying twice for the same CVE is the real failure mode.

Most AWS security breaches aren't caused by AWS failures — they're caused by misconfiguration. Here are 10 concrete best practices to harden your AWS environment in 2026.

Manual security triage cannot keep up with cloud-scale threats. Here is how to wire GuardDuty Extended Threat Detection, Security Hub, EventBridge, and Lambda into a self-healing AWS security architecture.
