ENTERPRISE READY
Zero-Trust AI Agent Control Plane

Every agent.
Every action.
Logged and governed.

AgentGate sits between autonomous AI agents and your enterprise APIs, intercepting every call, enforcing deterministic policy, and maintaining a tamper-evident audit ledger for compliance and liability defense.

Inline enforcement between agents and your infrastructure.

AgentGate intercepts every outbound call from LangChain, AutoGPT, CrewAI, or any agent framework before it reaches your APIs, databases, or external services. Policy is enforced deterministically — not probabilistically.

Request Flow
01
Agent Framework (LangChain, CrewAI, etc.) generates a tool call
via egress
02
AgentGate Proxy — intercepts, reads Agent Identity Card, checks TTL, validates scope against policy engine
decision
03
Permit → modified → blocked → or HITL
action logged
04
AI-Ledger — append-only, hash-chained record of decision + context
Policy Enforcement Matrix
PERMIT
Scope matches, TTL valid, within blast radius, data residency satisfied → call forwarded
MODIFY
PII detected in payload → fields masked before forwarding; parameter sanitized per schema
BLOCK
Out-of-scope call, expired token, cross-border PII without anonymization → call rejected, agent notified
HITL
Decision above threshold (financial, PII, cross-border) → action suspended, human reviewer notified via queue
Core Capabilities

Four layers. One control plane.

AgentGate is built from the ground up for enterprise agent governance. Not monitoring. Not observability. Actual enforcement at runtime.

Zero-Trust Egress Proxy

Every agent API call passes through AgentGate. No exceptions, no bypass paths. The proxy is the enforcement point — not an advisory layer.

Proxy Layer

Deterministic Policy Engine

Policy is defined in code, not inferred by ML. Every rule is explicit, auditable, and version-controlled. Deterministic means provable — no guesswork.

Policy Engine

Agent Identity Cards

Cryptographically attested identity per agent session. Ephemeral tokens, scope boundaries, financial blast radius caps, data residency gates — all in one JSON schema.

Agent IAM

Immutable AI-Ledger

PostgreSQL append-only ledger. Every decision logged: prompt, chain of thought, tool selected, execution, result. Hash-chained for tamper evidence. SEC-ready.

Audit Ledger

Human-in-the-Loop Queue

Actions exceeding defined thresholds — financial transactions, PII access, cross-border movement — are suspended and routed to a reviewer queue for human decision.

HITL Controls

Multi-Framework Support

Works with LangChain, AutoGPT, CrewAI, custom frameworks. MCP protocol-native. Connects to your existing identity provider (Entra, Okta, Asgardeo) via standard OAuth2.

Framework Agnostic
Agent IAM

Identity cards for every agent, every session.

Each agent is issued an Agent Identity Card at runtime — a signed JSON document that defines exactly what it can do, for how long, and under what data residency constraints.

Token Lifecycle
Agent authenticates to AgentGate IAM via OAuth2 / SPIFFE
Identity Card issued: scope, TTL, blast radius, residency constraints — signed JWT
Every call carries the ephemeral token. Token checked on every intercept
On expiry or scope violation: token revoked, agent must re-authenticate
AI-Ledger

The audit trail that shields you from liability.

Every agent decision logged to an append-only PostgreSQL ledger. Hash-chained for tamper evidence. Structured for SEC, DORA, and EU AI Act compliance audits.

000847 Agent attempted POST /api/v2/orders — $127,400 exceeds blast radius cap of $50,000 2026-06-17 13:04:22 blast_radius_v1 HITL

Ledger Properties

Append-only PostgreSQL. INSERT-only permissions. Merkle hash chain for tamper evidence. Every entry cryptographically verifiable.

  • Insert-only role (no UPDATE/DELETE)
  • Merkle root per block
  • Timestamp at database level
  • Chain integrity verifiable on-demand
  • Schema: prompt → CoT → tool → exec → result

Chain of Custody

Each audit entry maps to a specific human owner, a specific agent, a specific decision. The full decision graph is captured — not just the outcome.

  • Agent DID → human owner mapping
  • Full prompt + chain of thought
  • Tool parameters at time of call
  • Execution result and latency
  • Policy version that applied
EU AI Act / SEC / DORA

Compliance built in, not bolted on.

AgentGate's audit ledger and policy engine map directly to regulatory requirements. Generate compliance evidence automatically — not retroactively reconstructed.

EU AI Act

High-risk AI system compliance for autonomous agents in regulated environments.

  • Article 12 — Logging requirements
  • Article 13 — Transparency obligations
  • Article 14 — Human oversight mandates
  • Article 17 — Risk management system
  • Automated compliance grading

SEC / DORA

Financial services agent accountability for AI-driven decisions in capital markets.

  • Chain of custody for trading agents
  • Decision attribution to human owner
  • Immutable audit for regulatory review
  • DORA ICT risk management (Art. 6-11)
  • Automated evidence pack generation

GDPR / Data Residency

Data residency enforcement and PII protection across regional boundaries.

  • Cross-border PII transfer prohibition
  • Localized proxy anonymization
  • PII masking on egress
  • Right-to-explain for automated decisions
  • Data residency per Agent Identity Card

Each scenario simulates a LangChain agent calling a corporate API. The proxy evaluates each call against policy rules — then writes an immutable entry to the audit ledger.

Enterprise agents need
enterprise governance.

AgentGate is the control plane that lets you deploy autonomous AI with confidence — knowing every action is logged, every decision is policy-enforced, and every audit trail is defensible.
