Hirsch and Unibeam have introduced SecureSIM, an enterprise authentication option that roots a user’s identity in the secure element of their mobile SIM rather than in an app, a code, or a separate physical token. Built on Unibeam’s technology and folded into Hirsch’s identity portfolio, the offering uses SIM, eSIM, and iSIM identifiers as a hardware anchor for phishing-resistant access.
The mechanism binds a cryptographic credential to the protected hardware already inside a phone. SecureSIM ties a secure SIM element to the user’s device, so authentication is anchored to a tamper-resistant component rather than to a one-time code that can be intercepted or a token that has to be issued and replaced. Because the binding lives on the SIM, the companies say it can be provisioned remotely and used through a person’s existing mobile phone, removing the logistics of distributing dedicated hardware keys.
Phishing resistance is the core pitch. A credential bound to the SIM and the device is not a secret that can be phished, relayed through a fake login page, or extracted by social engineering, which are the failure modes that make SMS codes and shared passwords weak. The companies frame the approach as hardware-rooted verification that closes those gaps while keeping the user experience close to simply using their phone.
“SecureSIM powered by Unibeam gives our customers another powerful tool to counter today’s threats through hardware-backed security,” said Louis Modell, Global General Manager and Vice President of Identity Readers Americas at Hirsch. Ran Ben-David, Chief Executive Officer and Founder of Unibeam, said combining Hirsch’s identity ecosystem with SIM-based authentication lets organizations adopt strong, hardware-rooted verification. The companies note that compromised or stolen identities feature in more than 80 percent of breaches, the pressure driving demand for stronger methods.
SecureSIM joins a portfolio that already spans other phishing-resistant approaches, sitting alongside Hirsch’s SecureKey line of FIDO hardware keys and its SecurePass credential-driven authentication. The SIM-bound model offers an alternative to dedicated FIDO security keys such as Yubico’s YubiKey, addressing the same phishing-resistance goal that has driven enterprise adoption of passkeys and hardware authenticators but using the device a worker already carries.
