You ship it.
Jack watches it.

You built the app with Claude Code or Cursor and pushed it to a VPS. Nobody is looking after that box. Jack is: he reads the threat feeds every hour, checks them against what your servers actually run, and tells you the few things that matter. He never changes anything without your OK.

Jackmorning run · sample
  1. feedsCISA KEV, Ubuntu USN, Debian, 6 news feeds. 214 new items.
  2. match3 servers, 1,912 packages. Distro backports count as fixed.
  3. skip183 items: not installed on any of your servers.
  4. skipCVE-2026-40211 nginx: already fixed on web01 and app02.
  5. flagCVE-2026-31337 openssl on web01. Exploited in the wild.
  6. jackOne package update fixes it. Want me to queue it? You approve, I run nothing before that.

01What Jack does

  1. Watches your servers

    OS, packages, services, containers, open ports, certificates, disks, backups. A fresh look every 15 minutes, so he knows what each box runs today, not what you think it runs.

  2. Reads the threat feeds

    CISA's exploited list, Ubuntu and Debian security notices, security news and Hacker News. All of it, every hour, so you don't have to.

  3. Tells you what affects you

    Most advisories are about software you don't run. Jack matches on the exact distro version and drops the rest. What's left comes with the fix: usually one update.

  4. Asks before he touches anything

    The agent is read-only. Jack can suggest a fix and show you exactly what it does. Nothing runs on your server until you approve it.

02Two walls, one glance

Put the Security Wall on a spare screen and you know how the fleet is doing from across the room. The Threat Wall is the feed behind it: every threat that touches your servers, with the server, the package and the version that fixes it.

The Security Wall: a fleet score of 38, critical, with four things to act on today and a list of servers with their worst problem.
Security Wall Fleet score, what to do today, which server is worst. Jack says it in one line at the bottom.
The threats scene of the Security Wall: five things to fix, with exploited OpenSSL and kernel updates per server.
Threats on the wall Exploited first. One card per fix, not per CVE.
The Threat Wall page: an OpenSSL card from CISA KEV, Ubuntu and Hacker News, marked affects you, with the servers and fixed versions.
Threat Wall Clear it, mark it fixed, snooze it, or ask Jack what it means for you.

03How it works

  1. Install the agent. One command per server. A small Go binary and one systemd service.
  2. It reports out. The agent calls Jack over HTTPS. It opens no port and you hand over no SSH keys.
  3. Jack does the reading. Feeds in, your package lists in, a short list of what matters out: on the wall, by mail or in your coding agent.

04Ask Jack from Claude Code

Your coding agent deployed the app, so let it ask about the server too. Jack comes with an MCP server: Claude Code, Cursor and other MCP clients can list your servers, read the threats and request a fix.

Request, not apply. There is no tool that changes a server. A requested fix waits in the app until a person approves it.

05Private beta

Free while it's a beta.

We are letting in a small group of builders and agencies with real servers in production. Pricing comes later, and you'll hear it before anything costs money.

Tell us what you run and we'll get back to you.

We use your address for one thing: inviting you to the beta. No newsletter, no sharing, no tracking on this page. Want it deleted? Mail jack@gotyourbackjack.com.
