Legacy security
Frontier security
Threat model
Known malware, human-paced intruders
Autonomous agents and self-rewriting code, at machine pace
The clock
Patch in days; alerts a human triages
Exploited before the patch exists — handoff in ~22 seconds
The adversary's AI
Assumed to refuse the worst asks
Refusal removed with one command — assume no limits
Attack surface
Network, endpoints, inboxes
All of that, plus the agent layer: prompts, tools, MCP
Where you defend
Perimeter and SIEM, after the fact
The effect layer, as it happens, at machine speed
The red team
One human pentest a year
Continuous autonomous adversary emulation
COARK is built entirely in the right-hand column — a frontier white-hat team for the frontier threat.
