Polyguard Secure Line - Mobile App

The Polyguard Secure Line (PSL) Mobile App, available for iPhone with an Android version coming soon, is a turn-key security upgrade for anyone’s daily experience. Working as a drop-in replacement for the default Phone app, it adds strong identity verification to each end of any call made with another PSL user. It also provides malicious number blocking on both inbound and outbound calls, and can be used to verify identity for other Polyguard apps such as Polyguard Verified Meetings.

  • With a driver's license in hand, enrollment takes less than 30 seconds. Making and receiving secure calls is automatic - simply a click on your contact list.

  • Polyguard is the first security vendor to fuse 2D and 3D biometric processing, matching the industry's best rate for FMR under ISO/IEC 2382-37.

  • Many of the world’s largest security vendors have themselves become part of the problem, thanks to massive data breaches that have armed attackers with huge volumes of personal data. With Polyguard, personal biometric data stays on the phone, encrypted, not in the cloud.
