I'm biased on this, as project lead for Matrix, but: we've done loads of work to support Matrix for corporate communication - especially as a route to migrate away from Skype For Business, or a secure alternative to Slack & Teams. I'll try to give a balanced view: Good stuff: * OIDC for authentication (or CAS or SAML or LDAP etc) * "Spaces" to organise all your rooms across the organisation (and overlapping organisations) * Audit bot for compliance (a bolt-on in Element Enterprise) * "Group Sync" to bridge space membership and permissions to Active Directory (a bolt-on in Element Enterprise) * Loads of clients for different environments, and a really nice open API for writing new ones and bots and integratinos. * Bridges to existing corp systems like Slack and Teams to help do a rolling migration. * Great E2EE voip/video confs via Element Call (and Video Rooms) these days. * Federation, obviously, to work with other deployments within or between orgs, if you want. Bad stuff: * E2EE makes it hard for new users to see history when you join encrypted rooms. We're working on this currently. * Not as many integrations as Slack or similar yet - we really need to provide slack-compatible webhooks out of the box so we can leverage existing integs. * E2EE search doesn't exist on mobile yet * Lack of multiaccount makes juggling corp & personal accounts a pain.
