Silent OS provides a strong foundation for the type of users Blackphone will attract. It has no gratuitous features, no hooks to carriers, and no leaky data by default. Onto that base we then install our included tools and give the user full access to permissions, the ability to create completely independent Secure Spaces within one device, and other security settings via the Blackphone Security Center.
We control all the updates to Silent OS ourselves, and will release them directly to the entire Blackphone user community, without having to wait for carriers to approve the updates. Silent OS has the world’s fastest vulnerability management. Critical vulnerabilities are patched within 72 hours of detection or reporting, and updates come directly from Silent Circle, with no carrier delays or waiting periods.
We build Silent OS on Android because we feel that is the best option. It is a robust mobile operating system with a vibrant developer community, widespread adoption among existing users and devices, and tremendous flexibility to be adjusted to suit our detailed requirements.
