Secure Chat for BlackBerry vs Colloqui

Secure Chat for BlackBerry is an enterprise-ready messaging and collaboration platform that pairs the proven open-source Mattermost client with the BlackBerry Dynamics SDK. It delivers the real-time team communication your people expect — channels, direct messages, file sharing, and search — inside a hardened, containerized environment that your security and IT teams fully control. POWERED BY THE BLACKBERRY DYNAMICS SDK Built on the BlackBerry Dynamics SDK — the same technology trusted by governments and Fortune 500 enterprises — the app delivers three layers of protection. Strong authentication verifies every user before access is granted and integrates with your identity provider. A secure, encrypted container isolates all application data from personal apps and encrypts it at rest with FIPS-validated cryptography. And a VPN-less secure tunnel connects directly to your on-prem Mattermost servers, so corporate traffic reaches your infrastructure without exposing it to the open internet, opening firewall ports, or deploying a device-wide VPN. SECURITY YOU CAN PROVE Data-loss-prevention controls restrict copy, paste, screenshot, and "open in" actions so corporate information cannot leak into unmanaged apps. Jailbreak and root detection block compromised devices. Remote wipe lets administrators revoke access and erase app data instantly when a device is lost or an employee leaves — without touching personal content on the device. FULL ENTERPRISE IT CONTROL Deploy and manage at scale through BlackBerry UEM and your existing identity provider. Administrators set and enforce per-app policies — authentication strength, passcode rules, offline limits, and network access — without manual device setup. Certificate-based authentication and single sign-on streamline access while keeping it locked down. BUILT FOR COMPLIANCE Designed to help organizations meet frameworks such as HIPAA, GDPR, and data-residency mandates. Self-hosted and private-cloud deployment keep your data on your infrastructure, in your jurisdiction. EVERYTHING YOUR TEAM NEEDS - Organized channels for teams, projects, and topics - One-to-one and group direct messages - Secure file sharing and inline previews - Powerful search across messages and files - Threaded conversations to keep discussions focused - Push notifications with configurable content privacy - Cross-platform continuity with desktop and web OPEN FOUNDATION, HARDENED DELIVERY Built on the transparent, auditable Mattermost codebase and wrapped in the trusted BlackBerry security layer, Secure Chat for BlackBerry gives you the collaboration features teams want and the assurance compliance teams require.

Colloqui is a team messenger you host yourself. Your conversations live on your own server — not ours, not anyone's cloud. Connect the app to your self-hosted Colloqui server and get everything a modern team messenger should have, with a fully native iOS experience: • Channels organized into spaces, plus private channels and direct messages • Threads to keep discussions tidy • Rich formatting: bold, italic, lists, quotes, code, and task checklists • Tasks: any checklist line becomes a trackable to-do across your team • Reminders that fire even if your server is briefly unreachable — the app schedules a local backup alarm for every reminder • Pins, full message search, link previews, reactions, and file sharing • Presence, typing indicators, and instant delivery over a live connection • Offline-first: read your messages and queue replies and reminders with no connection; everything syncs when you're back • Optional two-factor authentication (TOTP) • Light and dark themes, compact mode, and a native keyboard-first composer Colloqui is built for people who want ownership of their data. There are no accounts with us, no analytics, no tracking — the app talks only to the server you point it at. Requires a self-hosted Colloqui server. Setup takes one Docker command — see the project site for the server.
