AI code security reviews for modern engineering teams

Find the vulnerabilities scanners miss.

Tachyon reviews every PR in full-codebase context, validates exploitability, and gives developers fix-ready findings before code merges.

Validated vulnerabilities in MLflow, OpenWebUI, Gradio, AutoGPT, and more.

Example finding

PR #1842 · tenant file downloads

apps/api/src/FileController.ts

High
37
class FileController {
40
// Download endpoint used by all tenants
41
async downloadFile(req: Request, res: Response) {
42
const { tenantId, fileId } = req.query;
43
const file = await storage.getById(fileId);
44
return res.download(file.path);
45
}
46
}

Missing tenant isolation

Tachyon validated that user-controlled file IDs can fetch another tenant's file before the authorization check runs.

Sourcereq.query.fileId
Sinkstorage.getById(fileId)
Missing checkfile.tenantId === tenantId

Suggested fix

Scope the lookup by tenant or verify ownership before returning the file path.

Built for code review, not noise

Tachyon reviews each pull request in full repository context, validates exploitability, and delivers fix-ready findings inline — so engineers ship secure code without waiting on security review.

Full-codebase context

Tachyon reviews each PR against your entire repository — tracing data flows, auth boundaries, and trust transitions across files. Not single-file pattern matching.

Exploitability validated

Every finding includes the attack path and proof of reachability. Tachyon validates exploits before alerting, so you fix what matters and skip the noise.

Inline PR feedback

Findings appear as PR comments with the vulnerability, the attack path, and a recommended fix — right where developers are already reviewing code.
