What we're shipping
Today, Aegis v0.1 Shield Preview is live. It's a single Rust binary that sits between your AI stack and the outside world — catching prompt injections, wallet drainer payloads, and PII leaks before they reach your model.
Install it in 60 seconds:
curl -fsSL https://get.aegis.dev | sh
What Shield includes
- Local LLM classifier — fine-tuned and optimized, running in-process via direct FFI. No HTTP calls. No sidecar containers.
- 50+ injection patterns via Aho-Corasick DFA — deterministic matching at sub-millisecond speed.
- PII detection — credit cards, SSNs, API keys, private keys, wallet addresses.
- Gateway proxy mode — reverse proxy that routes AI endpoint traffic through Aegis with zero code changes.
- Rules engine — TOML-based configuration with sane defaults.
- Structured JSON logging — via the
tracingcrate, ready for your existing log aggregation.
The entire Shield tier is free. Not a trial. Not freemium with the good features gated. The full LLM classifier, every detection pattern, unlimited requests. Free forever.
Why local-first
Every other AI firewall on the market is a cloud SaaS API. You send your AI traffic to their infrastructure, they scan it, then forward it. That adds 200ms+ of latency, creates a new attack surface, and means your prompts and user data transit through someone else's servers.
Aegis runs on your machine. Median latency: 2ms. Zero cloud calls. Works completely offline after install.
What's next
Shield Preview is the foundation. We're already building Sentinel — the paid tier with transparent proxy mode, custom pattern authoring, live threat intel feeds, and Prometheus metrics export. Designed for lean startups running AI agents in production.
Pre-orders for Sentinel are open now. Learn more about Sentinel →
