# Welcome

Real-time security monitoring for onchain finance.

Every 1.3 days, a protocol loses millions to preventable exploits. Audited code gets attacked through price manipulation, governance exploits, and runtime vulnerabilities that static analysis can't catch.

Guardrail monitors your contracts 24/7, alerting you in under 1 second when attacks begin—so you can respond before funds disappear.

## What You Get

**Instant Setup** — Pre-built guards for common attack vectors like reentrancy, flash loans, and oracle manipulation.

**Custom Protection** — Our security team builds monitoring tailored to your protocol's unique architecture and risks.

**Automatic Response** — Pause contracts, trigger alerts, or execute incident response playbooks without manual intervention.

**Multi-Chain Coverage** — 45+ EVM chains supported, plus Solana and Sui. Bridges, DEXs, lending protocols, and more.

## Trusted By
