Introduction to ESS Pro [WORK IN PROGRESS] Element Server Suite Pro (ESS Pro) is the commercial Matrix distribution from Element for professional use. It is based off ESS Community and includes additional features and services that are tailored to professional environments with more than 100 users up to massive scale in the millions. ESS Pro is designed to support enterprise requirements in terms of advanced IAM, compliance, scalability, high availability and multi-tenancy. ESS Pro makes use of Synapse Pro to provide infrastructure cost savings with unmatched stability and user experience under high load. It uses Element’s Secure Border Gateway (SBG) as an application layer firewall to manage federation and to ensure that deployments stay compliant at any time. ESS Pro includes L3 support, Long-term Support (LTS), Advanced Security Advisory and prepares customers for the Cyber Resilience Act (CRA). This documentation provides all information for Element customers to get started as well as to work with ESS Pro.

Contents TOC Deploying ESS Pro ESS Pro comes as a Helm chart and can be deployed using any Kubernetes distribution. It requires an existing Kubernetes cluster and can be operated on the public internet as well as in airgapped scenarios. A full step-by-step deployment guide for ESS Pro using K3s can be found here . Components Next you find an overview of the components in ESS Pro including their purpose and additional information. Most of the components get deployed by default but some of them require additional configuration first. Any component can be enabled/disabled as desired. The following components are included in ESS Pro (bolded items are being deployed by default): Synapse Pro Matrix Authentication Service (MAS) Dex (for LDAP support) Element Web Element Call / Matrix RTC Advanced Identity Management (AIM, formerly Group Sync) Secure Border Gateway (SBG) Sygnal (Push Gateway) PostgreSQL database .well-known delegation Find below more details on each of the components, information about their capabilities and our recommendations for deployment. Synapse Pro Purpose The Matrix server that provides client-to-server and server-to-server APIs Consists of Synapse and additional Pro components that improve performance, scalability and stability Deployment recommendations Enabled and deployed by default. Should only be disabled if there is an external Synapse deployment to be used instead. Works out-of-the-box with default configuration. For advanced configuration, see the below guide. Deployment and configuration guide Documentation Matrix Authentication Service (MAS) Purpose Authentication server for Matrix using the OpenID Connect / OAuth 2.0 standard Provides local user management capabilities Allows integration of external IDM systems Deployment recommendations Enabled and deployed by default. Should only be disabled if Matrix legacy authentication is required. Works out-of-the-box with default configuration. For advanced configuration, see the below guide. Deployment and configuration guide Authentication configuration guide (LDAP / OIDC) Documentation Dex (for LDAP support) Purpose Lightweight Identity Provider supporting various protocols Only used for LDAP support with MAS Deployment recommendations Disabled by default as enabling it requires configuration Automatically enabled if LDAP authentication is configured Authentication configuration guide (LDAP / OIDC) Element Web Purpose The browser-based client from Element Deployment recommendations Enabled and deployed by default.
