Secure communications software, built for your organisation.
Meridian is a Belgian technology company developing communications software for government bodies, defence organisations and private operators, with international ambitions. We can build messaging, voice, video and file-sharing applications around your users, hosting and security requirements.
Your own communications application.
Commission a dedicated communications application for your organisation and its approved partners. We define the conversations, calls and information-sharing features your teams need, then build around your hosting, identity and security requirements. Integration with Meridian Platform is optional.
What we can build with your team.
Private and group messaging
Build direct and group conversations for desktop and mobile, with the user directory, participant management and message-handling rules agreed for your organisation.
Voice and video calls
Develop one-to-one and group calling workflows, with voice and video in the same application. Call controls, participant access and network requirements are defined for your project.
Files and information sharing
Exchange documents, photos and attachments with authorised colleagues and partners. Define who can access shared information and how it is stored and retained.
Security and deployment
Design around your authentication, encryption, key management and device requirements. Choose the hosting approach and validate the complete system against the agreed security and acceptance criteria.
Our platform shows related work.
These screens show case chat and field communication already built within Meridian Platform. They illustrate relevant development experience. A standalone communications application is a separately scoped project; it can also connect to the platform when that serves your needs.

Security requirements are assessed per deployment. We do not claim accreditation for classified use; the field app’s full offline mode remains in development.
From requirements to a tested deployment.
Define the mission
Identify users, information sensitivity, network constraints and the systems already in place.
Build and exercise
Develop a focused workflow and test it with operators, including access revocation, connection loss and the fallback channel.
Deploy and support
Agree acceptance criteria, documentation, updates and support responsibilities before operational use.
Secure communications, explained.
Can Meridian build communications software for our organisation?
- Meridian designs and develops secure communications software for government bodies, defence organisations and private operators. We can build standalone applications for messaging, voice and video calls, and file sharing, tailored to your users and security requirements.
Do we need Meridian Platform to commission communications software?
- No. Meridian can develop a standalone communications application without requiring Meridian Platform. Messaging, voice and video calls, file sharing, hosting and security controls are defined for the project. Integration with Meridian Platform or other systems is optional and agreed during scoping.
Is Meridian accredited for classified communications?
- Meridian does not claim accreditation for classified communications. The intended information sensitivity, encryption, key management, device controls and approval requirements must be assessed for each deployment. The complete system is validated against the agreed use and acceptance criteria.
