Who Did That? Why Every AI Event Needs a User Attached

HIPAA's first technical safeguard, NIST 800-171's audit trail, EU AI Act logging — all reduce to one question your AI stack must answer: which user caused this call?

In-Process Runtime Governance: Enforce Before the Prompt Leaves

Dashboards observe, proxies intercept from the wrong side of the trust boundary. Why EU, healthcare, and defense compliance all point at enforcement inside the process.

Runtime Security for AI Agents: Why Static Guardrails Are Not Enough

Static rules don't know what happened two calls ago. Runtime enforcement does — with dynamic tool control, token monitoring, human approval gates, and a real-time DLP layer.

Why SDK-Based AI Security Beats AI Proxies

Proxies are blind to local models, add latency on every call, and route your prompts through a third party. An SDK enforces from inside the process — with code examples to show the difference.
