## Why Matrix, why now

Matrix is an open protocol for secure, decentralized communication. Unlike Signal or WhatsApp, organizations run their own homeserver - they own the infrastructure, the data, and the governance. That sovereignty is exactly why the public sector and regulated enterprises are adopting it at scale.

Germany's armed forces run **BwMessenger**, France's public administration runs **Tchap**, and **Element Server Suite** deployments are spreading across European government and enterprise. These are regulated environments with the same supervision and recordkeeping obligations as any bank or broker-dealer. We reference them here only as evidence that Matrix adoption is real and growing - not as customers, partners, or endorsements of Comma.

The organizations standing up sovereign Matrix homeservers still need an immutable, searchable archive with supervision and legal hold. That is the gap Comma is building to close.

## Three things we get right

## How the capture works

Because the customer controls their own homeserver, capture is a participant on that homeserver rather than an interception in transit. Four parts work together.

## What we can and cannot do

We would rather over-communicate the limits than let a Matrix-literate team discover them later. Encrypted-room capture is participant-based and prospective, on a homeserver you control.
