TL;DR: Secure communications for public authorities now have to span TETRA networks, mobile apps, and web clients while preserving sovereignty, compliance, and real-time coordination, according to SSH Communications Security. The governance challenge is not just encryption, but identity, access, and control across device types, deployment models, and mission-critical workflows.
NHIMG editorial — based on content published by SSH Communications Security: interoperable critical communications for public authorities
By the numbers:
Questions worth separating out
Q: How should public authorities govern secure communications across TETRA and modern messaging apps?
A: They should treat the integration as an identity and access problem, not only a networking problem.
Q: Why does interoperability increase risk in mission-critical communications?
A: Interoperability increases risk because each system may have different rules for authentication, authorisation, logging, and retention.
Q: What should teams look for in a sovereign secure messaging deployment?
A: Teams should look for control over data location, administrative access, audit scope, and policy enforcement.
Practitioner guidance
- Define cross-network access policies Map which roles may move from TETRA workflows into secure messaging, which devices are permitted, and what authorisation changes when a user crosses channels.
- Align deployment model to governance requirements Choose the service deployment option that matches residency, oversight, and administrative control requirements for your authority or critical-infrastructure environment.
- Extend auditability across communication channels Ensure messages, chat rooms, and audio/video sessions retain consistent logging, retention, and review controls when they move between devices and platforms.

Secure communications is becoming an identity problem, not just a transport problem. Once a mission-critical channel spans TETRA, mobile apps, browsers, and desktop clients, the trust boundary moves from the network layer to the identity layer. That means access policy, device trust, and operator accountability have to be consistent across every path into the collaboration system. For practitioners, the real test is whether the communication workflow still behaves securely when the user changes devices or environments.
A few things that frame the scale:
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage, according to the Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which is a useful warning sign for any team bridging operational channels and secure applications.
A question worth separating out:
Q: How do you manage access when field personnel use multiple devices and channels?
A: Use role-based access rules that follow the operator across approved devices, then narrow them with device trust, session controls, and reviewable audit logs. The goal is to keep response fast while preventing uncontrolled expansion of access. Lifecycle governance should include onboarding, temporary assignment, and offboarding for every communication path.
