Passenger safety depends on reliable communication. ATM voice systems are mission-critical and must be protected against manipulation and disruption. With Let’s secure voice, Frequentis is setting up a market initiative to strengthen voice security across development and implementation. 
 

Security is already built in and evolving further 

Our X10 voice system and the underlying MosaiX platform already include proven security mechanisms, such as certificate-based authentication and distribution, secure system architectures, and controlled access to critical interfaces. 

At the same time, we actively contribute to EuroCAE working groups to extend security beyond system boundaries and implement security directly at the voice protocol level, supporting interoperable and future-proof ATM voice communication. 
 

Join the Let’s secure voice initiative

Secure voice systems are a shared responsibility. By working together on standards, architectures, and implementation, the ATM community can move faster and more effectively. Our intention is to foster market-wide discussion on voice security and its practical implementation, support the standardization of security mechanisms within EuroCAE ED-137, and have these mechanisms validated at the next voice interoperability event. 
 

Start implementing voice security now

To turn security principles into operational reality, practical deployment matters. A session border controller plays a key role by protecting voice interconnections, enforcing policies, and strengthening resilience and availability. 

As a concrete contribution to the initiative, Frequentis offers a session border controller free of charge in 2026, enabling ANSPs to quickly raise the security level of their ATM voice infrastructure.
