Shield watches every session.

From the moment you run protect, Thuban monitors your files in real-time for as long as your session runs. Every change is watched. Every threat is caught. You don’t need to remember to scan — just start Shield at the beginning of your session.

And Crucible proves it. Every defence is tested. Every test is logged. Evidence, not promises.

Want a 30-day key so your trial follows you across machines?

Optional. The scan above already ran with zero signup — this just emails you a key so Thuban remembers you next time.

Your code never leaves your machine, with or without a key.

✓ You’re registered

You’re 4 steps from a protected codebase

No config files. No dashboard to set up. Just one command.

Open your terminal

Any shell works — Terminal, iTerm, Windows Terminal, VS Code’s integrated terminal. Navigate to the project you want to protect:

cd your-project Click to copy

Run `npx thuban protect`

This single command installs nothing permanently — it activates Shield in monitoring mode, scans your codebase, and runs Crucible to verify the defences actually work. Takes about 2 seconds.

npx thuban protect Click to copy

See your security score

Thuban scans every file and prints a health score. You’ll see something like this:

Health score:      B+ (78/100)
Issues found:      23
Auto-fixable:      17
✓ Crucible verified: 28/28 defences confirmed

What “good” looks like: a B+ or higher is a healthy starting point for most projects — there’s always something to tighten, and that’s normal. An A means almost everything auto-fixable has been fixed. Anything below a C means real, fixable risk is sitting in your codebase right now — run npx thuban fix . --fix to clear the auto-fixable issues instantly.

Thuban is now watching

From this point on, Shield runs continuously in the background — you don’t need to remember to re-scan. It monitors every file write and every command your AI coding agent (Claude Code, Cursor, Codex, Gemini CLI, etc) tries to run, and alerts you the moment something looks risky:

Shield active — monitoring mode. Every file write and command is watched in real time.

You get all of it. Every feature. One install, one price.

There's no "Shield tier" or "Guardian add-on." Installing Thuban gives you Shield (real-time defence), Crucible (proves the defences actually work), Scanner (69-rule vulnerability & hallucination detection), Forge (rules built from real incidents), Cost Guard (catches AI agents that can silently rack up a huge bill), and Guardian (autonomous AI agent monitoring) — all of it, from the free tier up.
