Customers — case studies

Trusted by teams that can't afford to wait for upstream patches.

Customer remediation logs as we publish them — how teams running ZeroPatch got a CVE closed before the upstream vendor shipped one. We start with LegacyHive and CVE-2025-21756, and CVE-2025-29927. More remediation logs will follow as editorial sign-off wraps.

What's inside

  • Three live case studies you can read end to end — LegacyHive, CVE-2025-21756, and CVE-2025-29927.
  • One upcoming case study remains queued for editorial sign-off.
  • A clear invite: be the next referenceable team on this page.

Case studies

Read the remediation logs as we publish them.

Three published, one in editorial review. Each case study is a single timeline from public disclosure to shipped fix — proof-first, no marketing-led reordering.

LegacyHive

Six days from a public PoC to a free ZeroPatch micropatch — no paid seat, no upgrade cycle.

Free micropatch shipped 6 days after public PoC for CVE-2025-21756
CVE-2025-21756

Linux kernel vsock use-after-free — fix merged 11 hours before disclosure, exploit chain blocked on every patched host before the PoC dropped.

Fix auto-merged 11 hours before public disclosure — no customer interrupt.
CVE-2025-29927

Next.js middleware authorization bypass — the affected release lines, fixed versions, and audit-backed merge are all visible in one remediation log.

Critical remediation recorded as merged on 2026-09-02.

Coming soon — SaaS platform

A multi-tenant SaaS team that wanted pre-disclosure remediation on its core framework dependency without touching the source.

Will cover the design-partner loop, the false-positive filter shape, and how the agent opened PRs against the real production graph.
