Matrix / ESS

Private self-hosted communications, Matrix / ESS

We deploy dedicated Element Server Suite environments for sovereign, interoperable, and secure communications built on the Matrix open standard.

Your team's chat, on your servers

Matrix is an open standard for real-time communication, and Element Server Suite (ESS) is the enterprise platform built on it. Messages, files, and calls stay on your infrastructure or in an EU data centre — not with a SaaS vendor.

ARCSoft installs, configures, and operates ESS for you: from domain and certificates to backups and updates. We use Matrix every day in our own team.

  • Dedicated Matrix server with Element Web and the Element mobile apps
  • End-to-end encryption for messages and calls
  • Single sign-on (OIDC) with your company's existing identities
  • Controlled federation with partners, or a fully isolated server
  • Hosting on-premise or in a private EU cloud
