Adversary Emulation with CALDERA & Atomic Red Team

A pentest finds vulnerabilities; adversary emulation asks a sharper question — if a specific real-world threat actor targeted us, would we detect them? This is threat-informed red teaming end to end: pick an actor, map their TTPs to MITRE ATT&CK, build an emulation plan, then run it with Atomic Red Team (per-technique tests) and MITRE CALDERA (agent-based emulation). Then close the loop with purple teaming — measuring what the blue team detected and engineering detections for the gaps.
