# Glasswall Documentation

> Official documentation for Glasswall's Content Disarm and Reconstruction (CDR) technology and products — Halo, Meteor, Embedded Engine, Foresight, and REST APIs.

Glasswall CDR uses a zero-trust approach: every file is treated as potentially harmful, validated against its manufacturer's specification, and rebuilt to a known-good standard. Rather than detecting threats, Glasswall removes their ability to affect a document.
