Frequently asked questions
How does Silent Circle ensure a subpoena or internal leak cannot expose customer communications?
Encryption and decryption happen exclusively on the user's device; Silent Circle does not hold, escrow, or have the technical ability to retrieve the keys. Even if a government or a rogue employee demanded access, the company has nothing to surrender. This zero-knowledge design is the core architecture of Silent Phone.
What enterprise management controls does Silent Circle offer that consumer-grade encrypted apps lack?
Silent Manager provides centralized single sign-on, remote wipe of a lost or compromised device, and a virtual on-premises deployment option for organizations with strict data-residency requirements. IT teams can manage the entire encrypted fleet without touching individual handsets.
Which sectors does Silent Circle explicitly target?
The firm's public materials point to law firms, NGOs, and governments as primary verticals. Its blog further reveals a focus on healthcare organizations concerned with medical IoT risk and on enterprises navigating the tension between mobile productivity and regulated data protection.
Does Silent Circle sell to individuals or only to organizations?
The publicly available contact path is geared toward businesses, NGOs, and government agencies with at least 25 employees. The website does not present a self-serve individual plan, suggesting the product is sold through a direct enterprise sales motion.
How does the Security Words feature work?
Security Words combat voice-call interception by displaying a unique, pre-agreed word on both participants' screens during a call. If the words do not match, either party is alerted that the call may have been compromised or a man-in-the-middle attack could be underway.
