- Soverli enables multiple operating systems to run simultaneously on a single smartphone
- Mission-critical users can maintain workflow even if Android becomes compromised
- Employees can separate personal and business environments without sacrificing device functionality
A Swiss cybersecurity startup, Soverli, has announced a new approach to mobile security that works alongside Android and iOS on commercial smartphones.
The company aims to deliver a fully auditable operating system layer that can run independently, even if the underlying OS is compromised.
This architecture lets organizations maintain operational continuity without giving up the features and convenience users expect from standard devices.
Mission-critical applications and early adoption
Observers often compare Soverli’s model to Proton, applying a similar high-assurance approach to smartphones rather than email and VPN services.
Soverli’s initial use cases focus on mission-critical communication for public-sector organizations and first responders.
Pilots include emergency services, police, and firefighting units, where constant availability is essential.
By running a dedicated software stack in isolation from Android, essential workflows remain functional even during misconfigurations or attacks affecting the primary operating system.
