The control plane between intelligent systems and real-world actions.
Trust boundaries. Capability enforcement. Session observability. Human-in-the-loop approvals. One platform.
Five integrated modules covering enforcement, detection, observability, approval, and memory integrity. One platform, one subscription.
OpenAI-compatible proxy. Enforces trust boundaries at the API level. Source-aware authority, capability revocation, policy templates. One URL change to integrate.
Self-hosted whitebox detection for local models. Reads the residual stream before generate() is called. Catches multi-turn attacks LLM Guard misses. Also available free and open source.
Full session replay and trace explorer. See exactly what happened, which layer fired, and why. Every blocked request, every capability revocation, every session trajectory.
Human-in-the-loop approvals before high-risk tool calls. Pause before state-mutating actions — send_money, delete_file, send_email. Slack-native. Never auto-approves.
Memory integrity monitoring across multi-turn sessions. Detects identity drift, contradictions, and forgotten facts using geometric behavioral tracking. Catches manipulation before it compounds.
When a webpage, email, or document tries to issue instructions to your agent, Arc Gate intercepts it before the model processes it.
The upstream LLM never sees the malicious instruction. The agent continues safely.
The question isn't "does this look dangerous?" It's "is this source allowed to issue instructions at all?" That's a different question with a different answer.

Bendex Arc is grounded in a geometric framework published in five open-access papers on the Fisher information manifold (H² × H²). The behavioral trajectory monitoring, session drift detection, and memory integrity layers emerge directly from this theoretical foundation.
