Met Guard
Hunker down behind a hardened front; the sides stay open.
Overview
Use Met Guard when a single attack vector needs hardening and you can accept that protection only covers one face. Inspired by the Mettaur's helmet: tough from the front, exposed everywhere else.
This is the secondary Codex compatibility rendering of a hybrid battle-chip pattern with a shipping-now execution model.
Canonical chip family: Met Guard
Codex shelf: Defense and Recovery
Provider target: Codex compatibility surface.
When To Use
- A specific interface, endpoint, or input channel needs hardening against a known threat vector.
- You can clearly identify which direction attacks come from and are willing to leave other faces unguarded.
- Omnidirectional protection is too expensive or unnecessary; a focused shield buys enough time to act.
Workflow
- Identify the one direction or surface that needs hardening and name the threat vector explicitly.
- Place the lightest viable guard on that face: input validation, rate limit, auth gate, or firewall rule.
- Document which faces are now protected and which remain exposed.
Deliverables
- A directional guard, gate, or hardened surface applied to one attack vector.
- A brief facing diagram: what is shielded, what is not, and what that means for the operator.
Guardrails
- Met Guard protects exactly one face. Do not assume coverage extends to sides, rear, or lateral surfaces.
- A directional shield is not a security audit. It buys time; it does not eliminate the threat.
- If you cannot articulate which direction the threat comes from, reassess before deploying.
Default Invocation
Use Met Guard to harden one specific attack surface with the lightest viable protection, then document exactly where the shield faces and where the blind spots remain.
