# FYEO — Security Scanner and Expert Security Audits

> FYEO provides continuous security scanning with its own security reasoning model, alongside expert human-led audits for high-stakes releases.

FYEO Security Scanner reasons through code like a senior auditor rather than relying only on patterns from known bugs, helping identify flaws unique to your code. It covers smart contracts, APIs, integrations and dependencies. Scan types are PR audit, third-party dependency audit and full audit.

Start at https://scanner.fyeo.io: sign in with GitHub and get 50 free credits, no card required. The exact credit price is shown before every scan; failed scans are refunded automatically. Automated scanning is not a guarantee of security. Expert human-led review remains available for complex or high-stakes releases.

The MCP server connects Claude, ChatGPT and other MCP clients to estimates, scan progress and findings. Queueing scans is opt-in and off by default. An account owner enables AI apps access, reviews the quote and approves a scan before it is queued. The Partner API embeds security scanning inside another product with a free sandbox and test keys.
