Polyguard Secure Line - Mobile App

Identity-verified communication for your most sensitive conversations

The Polyguard Secure Line (PSL) Mobile App transforms ordinary calls into trust-verified interactions. Available for iPhone (Android coming soon), it works as a drop-in replacement for your phone app, adding military-grade identity verification to both ends of any call with another PSL user.

Recommending Polyguard to your clients demonstrates your commitment to protecting their financial wellbeing beyond just managing assets.

Built for financial professionals and their clients:

  • With a driver's license in hand, enrollment takes less than 30 seconds. Making and receiving secure calls requires no additional steps.

  • Polyguard is the first security vendor to fuse 2D and 3D biometric processing with hardware attestation, meeting the industry's highest standards for false match rates under ISO/IEC 2382-37.

  • Unlike systems that store sensitive data in vulnerable cloud databases, Polyguard keeps biometric data encrypted on the device, never leaving your phone.

  • Automatically blocks known malicious numbers for both inbound and outbound calls, providing an additional layer of defense against evolving threats.
