Trillian: modern, secure messaging for individuals and organizations

Trillian is a cross-platform communication app that combines instant messaging, file sharing, presence and searchable message history with centralized administration and compliance options for businesses and healthcare providers. With native clients for Windows, macOS and Linux, mobile apps for iOS and Android, and a browser-accessible web client, Trillian keeps conversations in sync across devices and platforms.

Core features and user experience

• Cross-platform clients — Native apps for desktop and mobile plus a responsive web client let users switch devices without losing context or message history.
• Persistent, synchronized history — Conversations and files sync to the cloud so you can resume chats and access attachments from any device.
• Real-time messaging and presence — Read receipts, typing indicators and presence statuses help teams stay coordinated without relying on email or SMS.
• File transfer and media — Drag-and-drop file sharing, inline image previews and searchable attachments support everyday collaboration.
• Group chat and channels — Create team rooms or topic channels to organize conversations, support projects and reduce noisy email threads.
• Notifications and mobile performance — Push notifications and lightweight mobile clients preserve battery life while keeping users informed.

Security, compliance and administration

• Security-first design — Transport encryption and server controls protect data in transit and at rest; suitable for organizations that need stronger controls than consumer messaging apps.
• Compliance options — Trillian offers deployment and configuration options designed to meet regulatory requirements such as HIPAA for healthcare organizations when configured and contracted appropriately.
• Centralized management — Admin dashboards, user provisioning and policy controls make it practical for IT teams to manage accounts, retention and feature access across an organization.
• Flexible hosting models — Cloud-hosted and enterprise-grade deployment choices accommodate different security postures and integration needs.
