# xounce

> xounce is an end-to-end automated, continuous validated vulnerability pipeline. It scans
> everything (SAST, SCA, secrets, IaC, DAST), then runs each finding through a proof gate —
> is the vulnerable function actually used in your code (reachability), is it reachable from
> the public internet (exposure), and can AI actually exploit it against a running target
> (a replayable proof-of-concept) — and only reports what it can prove. Confirmed findings
> with a clean fix arrive as a pull request (exploit proof in the body; a CI check re-runs
> the exploit against the fix). Everything the gate drops is retained for audit, off the
> main view, never silently deleted. Positioning: "We prove it. Then we fix it."
>
> The name comes from "bounce": xounce bounces what shouldn't get through back out —
> malicious code (the exploit gate), malicious requests and leaked data (the cross-domain
> track), and technical debt (the auto-fix PRs). The cross-domain track rebuilds API
> payloads inbound (a protocol break, so the backend never processes attacker-crafted bytes)
> and applies data-loss prevention (DLP) to responses outbound (secrets, tokens, PII and
> over-exposed fields never leave the boundary). AI probing uses distilled open-weight models
> tuned for speed and cost; enforcement is deterministic, with no model in the request path.
>
> Status: pre-launch, onboarding design partners (read-only, one repo, free while building).
