Enterprise AI Security

Execute AI with Absolute Certainty

Context Guard is a Rust-based execution interceptor that acts as a semantic firewall for your AI agents, guaranteeing deterministic identity isolation and protecting your databases, RAG systems, and document stores from rogue LLM actions.

Deploy Context Guard View Architecture

Example Code

proxy_interceptor.rs

// [INTERCEPT] Rogue LLM generated query

"DROP TABLE users;"

// [EVALUATE] Semantic Firewall Analysis...

! Structural violation detected.

! Mutating operation blocked.

// [REWRITE] Deterministic Isolation Injection

"SELECT * FROM context WHERE identity_context = 'user_123'"

The Data Plane Architecture

Context Guard sits directly inside your VPC, acting as a high-performance reverse proxy that guarantees security without breaking your agentic workflows.

1. Intercept

The client LLM application generates a raw database query, RAG retrieval request, or file access call. Instead of executing directly, it routes to the Context Guard proxy API.

2. Rewrite & Sanitize

The Proxy verifies the identity JWT, filters the payload against strict YAML rules, and forcibly injects the required identity_context to guarantee data isolation.

3. Secure Execution

The safely rewritten, strictly scoped query is returned to the client application and safely executed against your protected databases, vector stores, or document APIs.

Semantic Firewall

Intercepts and evaluates every automated AI query in real-time, blocking forbidden operations (like DROP or DELETE) before they ever reach your database.

Deterministic Identity Isolation

Mathematically guarantees that data remains siloed by enforcing hard-coded identity context and access policies across all AI interactions automatically.

Sub-2ms Latency Overlay

Built entirely in Rust, the Context Guard proxy operates as a hyper-fast data plane interceptor inside your VPC without slowing down your agentic loops.

Zero-Trust Infrastructure Access

Agents never hold direct database or API credentials. The proxy manages secure, scoped execution across databases, RAG systems, and file stores using enterprise-grade credential rotation.

Developer Experience

Context Guard abstracts away complex multi-tenant security logic. Route your AI's intended actions through our proxy to ensure compliance instantly.

  • Pull the optimized Docker image directly to your VPC.
  • Pass minimal context: agent_id and jwt_token.
  • Receive deterministic, fully sanitized execution payloads back.

Example Code

import requests

# 1. Send the LLM's intent to the Rust Proxy
response = requests.post(
    "http://localhost:8080/v1/proxy/execute",
    json={
        "agent_id": "copilot_01",
        "auth_token": user_jwt,
        "generated_sql": llm_generated_sql
    }
)

result = response.json()

# 2. Proxy returns safe execution context
if result["status"] == "APPROVED":
    safe_query = result["safe_query"]

# db.execute(safe_query) - SECURE EXECUTION
