OpenGovMail is an open-source communication platform initiated by the Lanka Software Foundation (LSF) which aims to provide public sectors with a highly scalable, secure, and sovereign messaging alternative that keeps sensitive data fully protected.

Secure and sovereign communication is foundational to effective public governance. However, many public institutions lack localized tools and frequently rely on commercial and propieratary platforms using private credentials.

OpenGovMail bridges this gap by offering an integrated infrastructure that combines email and chat with deep security controls suited for public administration. While its primary focus is facilitating public sector entities like governments, its applications are open to any organization requiring high-security communications.

• Unified Experience: Seamlessly integrates email and chat functionality into a single interface for public sectors.
• Deep IAM Integration: Extends beyond typical commercial offerings by deeply integrating with Identity & Access Management (IAM) systems to ensure managed and secure communication access.
• Built on Open Standards: Fully interoperable with traditional email protocols and leverages the Signal Protocol for robust, end-to-end encrypted instant messaging.
• Risk & Governance Controls: Designed from the ground up with strict risk controls, including signed forwarding, the complete elimination of client-side Bcc, internal-only accounts, and trusted domain tagging.
• 100% Open Source: Available under the Apache License and engineered to be deployed and operated completely locally on independent sovereign infrastructure.
