Built from real audit work
Proprietary models trained on 300+ audits, with a reinforcement-learning feedback loop from FYEO security engineers.
FYEO Security Scanner
AI security scanning for smart contracts, trained on 300+ real audits.
Built on FYEO's own security reasoning model. It reasons through smart contracts, APIs, integrations and dependencies like a senior auditor, helping catch flaws unique to your code—not just patterns from known bugs. Run PR, third-party dependency and full audits.
Your code is never stored after a scan.

A finding, end to end
What a finding looks like.
Every result is structured for a security review: evidence, exploitability, remediation, and an auditable verdict in one place.
- 1Ranked by severity, mapped to CWE
- 2Exact file and line, vulnerable code highlighted
- 3Plain-language exploit path and fix
- 4Confirmed by a FYEO auditor when it matters
How it works
From repository to reviewed finding.
01Connect a repo
Choose exactly which repository FYEO can access through GitHub.
02Scan
Run a full or diff audit in the background while your team keeps working.
03Triage
Review severity-ranked findings and escalate anything ambiguous to a human auditor.
Purpose-built and private
AI grounded in how auditors work.
The Scanner combines specialist models, FYEO audit experience, and strict source-code handling in one review workflow.
Fine-tuned for vulnerability classes
Purpose-built models run 10–20× faster than untrained cloud-based alternatives, with no per-token cost ceiling.
Self-hosted inference
Your code runs on FYEO infrastructure.
Least-privilege repository access
Grant access per repository. Source is processed for the scan and never stored afterward.
Flexible credit pricing
Pay for the scanning you need.
Start with 50 free credits. Pick a monthly plan, or buy credits as you go — no plan required.

Security Scanner FAQ
- How do I check if my vibe-coded app or smart contract is secure?
- Connect your GitHub repository to FYEO Security Scanner and run a full audit, then review the severity-ranked findings and fixes. Use PR audits for each change and dependency audits for third-party libraries. Automated scanning helps find vulnerabilities; it is not a guarantee of security, and high-stakes releases benefit from human review.
- Is there an AI security scanner that works with Claude or ChatGPT?
- Yes. FYEO Security Scanner connects to Claude, ChatGPT and other MCP clients through its MCP server. Connect your FYEO account to read scan results and request estimates. Queueing scans is off by default: enable AI apps access in your account and approve the quoted price before a scan is queued. See fyeo.io/mcp for setup.
- How much does a security scan cost?
- New FYEO Security Scanner accounts get 50 free credits, no card required. Scan costs depend on the scan type and repository size. You see the exact credit price before every scan, and failed scans are refunded automatically. Monthly plans start at $59; one-time top-up packs are also available. See fyeo.io/pricing for the current plans.
- How is FYEO different from using a general coding model to find bugs?
- FYEO is built on its own security reasoning model. It reasons through code like a senior auditor rather than relying only on patterns from known bugs, helping identify flaws unique to your code. Its review workflow produces severity-ranked findings with evidence, exploit paths and remediation for smart contracts, APIs, integrations and dependencies.
