# OnlyAllow.ai

> The first AI firewall — a zero-trust security system that riddle-tests AI agents before granting access to production systems. AI must prove competency, not just identity.

## What It Does

OnlyAllow.ai sits between your IAM layer and production infrastructure, requiring any AI agent to prove competency before accessing systems. The AI must solve a dynamically generated riddle built from real system knowledge — no knowledge means zero chance of access.

This is zero-trust security, but for AI.

## How It Works

The 5-step security pipeline:

1. ACCOUNTABILITY — System knowledge is onboarded (human-led or AI Brain auto-scan)
2. LOCK DATA — AES-256-GCM encrypts all data in transit
3. SPEED PASS — Returning AI with valid certificate skips to access (<1 sec)
4. RIDDLE — First-time AI solves a knowledge test built from real system data
5. SCORE — 100% = access granted. Anything less = denied

## Two Firewall Modules

Module 1 — Human-Led: A human manually onboards the AI with system knowledge. That knowledge becomes the basis for the riddle. Best for controlled environments.

Module 2 — AI Brain: The AI Brain auto-scans your systems and automatically generates optimal riddles from discovered data. Best for dynamic environments with many systems.

## Architecture

4-pillar system:
- Pillar 0: Platform Foundation — AES-256-GCM transport encryption, data normalization
- Pillar 1: Gate Layer — Authentication, riddle challenge dispatch, token management
- Pillar 2: Riddle Matrix — Self-hardening riddles that evolve based on failed attempts
- Pillar 3: Enclaves — Ephemeral sandboxed execution (optional Safe Room with auto-wipe)

## Key Capabilities

- AES-256-GCM encryption on all data in transit
- Cached Speed Pass for trusted AI agents (<1 second re-auth)
- Self-hardening riddle engine that evolves over time
- Safe Room enclave: no internet, no file saves, auto-destruction
- 141 TDD tests across all security layers
- Capability certificate issuance and caching

## Technology

- Backend: FastAPI (Python)
- Encryption: AES-256-GCM
- Containers: Docker, Kubernetes
- Infrastructure: Google Cloud Platform

## Who It's For

- DevOps teams gating AI access to infrastructure
- SaaS platforms verifying client AI agents
- Enterprises requiring SOC 2 / ISO 27001 compliant AI access controls
- Any organization where AI touches sensitive data

## Competitive Positioning

Traditional firewalls check identity. OnlyAllow checks competency. An AI agent that can't demonstrate knowledge of the target system cannot access it, regardless of valid credentials. The riddle system continuously evolves, so credential theft alone never grants access.
