Synentra — Intent-Aware Governance Gateway
Synentra is an open-source Intent-Aware Governance Gateway built on .NET, designed to secure, monitor, and control interactions between autonomous AI agents, microservices, and complex backend systems.
Where traditional API gateways route traffic based on static endpoints and basic credentials, Synentra introduces a semantic layer of security by evaluating the actual intent behind every proxied API call. This allows teams to establish dynamic guardrails that ensure AI agents and automated systems operate strictly within defined behavioural boundaries.
Key Capabilities
| Capability | Description |
|---|---|
| Intent-Based Policy Enforcement | Move beyond RBAC. Synentra analyses the underlying purpose of each request and enforces context-aware policies that govern what an agent is trying to achieve. |
| Human-in-the-Loop (HITL) Safeguards | High-risk, potentially destructive, or anomalous requests are automatically intercepted and held for a human operator to review and approve before execution. |
| Adaptive Risk Scoring | A composable, weighted risk-scoring engine evaluates each request across multiple dimensions — HTTP method, URL path, time-of-day, body size, and agent history. |
| Semantic Analysis | Optional LLM/ONNX-powered semantic evaluation classifies free-form request bodies or intent text for deeper policy decisions. |
| Precise Agent Governance | Each registered agent carries an identity, a trust score, and an assigned policy. The gateway enforces these per-agent rules on every proxied request. |
| Circuit Breaker | Protects upstream services from cascading failures by automatically opening the circuit after repeated failures and recovering automatically. |
| Rate Limiting | Per-agent request throttling prevents runaway agents from overwhelming downstream systems. |
| HITL Notifications | When a request is suspended for review, Synentra can notify reviewers via Slack, Microsoft Teams, PagerDuty, or a generic webhook. |
| Agent Quarantine | Automatically quarantine agents that fall below a trust score threshold, blocking all subsequent requests until manually lifted. |
Why Synentra?
Synentra is the only open‑source, intent‑aware governance gateway purpose‑built for autonomous AI agents that interact with enterprise APIs. It unifies deterministic policies, local semantic intent classification, and adaptive agent trust scoring – all delivered with sub‑30ms end‑to-end latency.
Differentiators
Real‑time, intent‑aware governance for AI agent actions – far beyond LLM chat supervision.
| Problem | Synentra Solution |
|---|---|
| Traditional API gateways (Kong, Tyk) block by path and method only – they cannot detect a dangerous request like “export all customers” in the payload. | Semantic intent classification (local ONNX model) understands what the agent is trying to do. |
| AI gateways (Portkey, Cloudflare) focus on LLM cost management and prompt security, not on governing downstream agent actions. | Agent trust scoring – each agent carries a dynamic risk score that evolves with every request. |
| Human‑in‑the‑loop typically demands custom code or external tools. | Built‑in HITL – suspend, approve, or deny actions directly via API, Slack, Microsoft Teams, or PagerDuty. |
| No visibility into which agent performed which operation. | Agent identity + JWT – provides a complete, per‑agent audit trail. |
Core Advantages
| Advantage | How Synentra Delivers It |
|---|---|
| Local, low‑latency intent classification | A fine‑tuned ONNX model (DistilBERT) runs inside the gateway – inference completes in under 20ms, with no external API dependency. |
| Agent trust scoring | A dynamic risk score (0.0–1.0) is continuously updated based on violation rate, HITL history, and anomaly detection. Policies can automatically quarantine low‑trust agents. |
| Hybrid semantic + deterministic policy engine | Combine fast JSON‑based attribute‑based access control (ABAC) with intent‑aware conditions such as input.intent == "bulk_export". Policies are hot‑reloadable and designed for GitOps. |
TL;DR
“Synentra bridges the gap between conventional API gateways and slow, cloud‑dependent LLM guards. It empowers enterprises to let AI agents act autonomously – while understanding why they act, continuously scoring their trust, and requiring human approval for high‑risk intents – all in under 20 milliseconds.”
What Synentra Is Not
- ❌ A generic LLM proxy (no token counting, no prompt caching)
- ❌ A cost‑control tool for the OpenAI API
- ❌ A load balancer or canary deployment tool
- ❌ A sidecar exclusively for MCP servers – it works with any HTTP API
Who Should Use Synentra
- Platform engineers – secure AI agent traffic without adding latency or operational complexity.
- Security architects – enforce compliance and maintain a complete audit record for every agent action.
- Compliance officers – achieve SOC 2/HIPAA readiness with built‑in human‑in‑the‑loop and auditable logs.
- AI agent developers (LangChain, Semantic Kernel, custom frameworks) – integrate once and govern every agent uniformly.
