Team chat software has to support routine communication while meeting your requirements for protecting and managing conversations. Compared on end-to-end encryption, audit logs, message retention, and SSO support, these options also cover file sharing and guest access. Mobile apps may matter for teams communicating away from a desk, while free-plan availability and paid-from pricing add cost considerations. The entries include 8seats, Rocket.Chat, and Wire. Weigh the listed security and collaboration features against who needs access, what information teams share, and how long messages should remain available.
29 secure team chat software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
