Eliminate TOCTOU race conditions and unverified socket exfiltration at Ring-0.
Deterministic, hardware-enforced syscall interceptor engineered for production agent swarms.

As enterprise deployments shift from stateless conversational LLMs to stateful, autonomous execution swarms (FastMCP, LangGraph, AutoGen), traditional application-layer guardrails fail to mitigate critical attack vectors. Semantic evaluators and regex interceptors introduce prohibitive latency penalties (500ms–2,500ms) and remain fundamentally susceptible to Time-of-Check to Time-of-Use (TOCTOU) exploitation, token obfuscation, and raw socket data exfiltration.
KSEC relocates defense boundary verification from user-space down to the Linux eBPF LSM & XDP kernel substrate. By coupling sub-35μs cryptographic intent-lease verification with in-kernel packet inspection, KSEC provides mathematical finality against sandbox escapes before execution passes the libc boundary.
