Unibeam and Hirsch have launched SecureSIM, an authentication solution that uses mobile SIM cards to verify identities. The technology is designed to protect enterprises against phishing and AI-driven identity theft by binding cryptographic identifiers to a user’s device.

SecureSIM operates by using the secure hardware element already present in SIM, eSIM, and iSIM cards. This method removes the need for physical security tokens or one-time password (OTP) interception, which are common targets for credential theft. The solution is carrier-independent and functions globally without requiring a dedicated mobile application.

The system is integrated into Hirsch’s existing identity security portfolio, which includes hardware keys and credential-based multi-factor authentication (MFA). By using the SIM card as a hardware-backed security anchor, organisations can deploy MFA remotely and immediately to distributed workforces.

“SecureSIM gives our customers another tool to counter today’s threats through hardware-backed security, without adding friction,” said Louis Modell, Global GM at Hirsch. He noted that the solution aims to reduce the operational burden of managing physical hardware lifecycles.

Ran Ben-David, CEO of Unibeam, stated that the collaboration enables organisations to adopt hardware-rooted verification that is scalable. The companies will demonstrate the technology at the Identiverse 2026 conference in Las Vegas.
