In today’s digital landscape, the urgency to address the vulnerabilities of traditional authentication methods, such as passwords and SMS-based one-time passwords (OTPs), is becoming increasingly apparent. Cybercriminals exploit these weaknesses, resulting in a sharp rise in identity theft, account takeovers, and financial fraud.
Enter Unibeam, an Israeli startup that has raised $6 million in seed funding to tackle the problem at its root. Led by NFX and joined by AnD Ventures, the investment will help scale Unibeam’s SIM and eSIM-based authentication technology: a frictionless, cryptographic alternative to vulnerable passwords and SMS-based OTPs.
The Growing Vulnerability of Legacy Authentication
The evidence is clear: traditional authentication isn’t just inconvenient; it’s actively insecure. In late 2024, the FBI and the Cybersecurity and Infrastructure Security Agency (CISA) issued a joint alert urging organizations to abandon SMS-based 2FA (two-factor authentication) altogether. They warned of growing risks tied to phishing, SIM swapping, and man-in-the-middle attacks.
Meanwhile, in the UK, SIM swap fraud surged by over 1,000% in 2024. The National Fraud Database reported a 1,055% increase in SIM-swap fraud incidents. This attack enables hackers to hijack mobile numbers, intercept one-time passwords, and take over bank accounts without the user’s consent.
Unibeam: Cryptographic Identity for SIM and eSIM Devices
With its newly announced $6 million seed round, Unibeam aims to enhance digital trust. Rather than rely on guesswork or data-heavy behavioural analytics, the company offers a deterministic authentication model rooted in hardware: the secure chip inside every SIM and eSIM card. This model binds identity to unique device and network-level identifiers, ensuring that only the legitimate user can authenticate.
Unibeam’s advantage lies in its security and ease of use. No apps to install, no passwords to remember, and no codes to enter. It works seamlessly across SIM and eSIM-equipped smartphones and feature phones alike. The system is fully API-based, scalable globally without compromising the user experience.
Why the Market Is Ripe for Disruption
Enterprises are actively seeking authentication tools that reduce both risk and friction. The global passwordless authentication market is projected to reach $55.7 billion by 2030, growing at a compound annual growth rate (CAGR) of 17.1% from 2025. Solutions like Unibeam, which remove humans from the loop, are becoming a necessity in the current digital landscape.
Rebuilding Digital Trust from the Chip Up
This is a foundational shift in how digital identity is handled. As attacks become more sophisticated, hardware-based, deterministic authentication is seen as a potential solution to restoring trust. Unibeam’s cryptographic solution provides a future-proof way to authenticate users without introducing user friction.
Key Points
- Unibeam has raised $6 million to develop SIM and eSIM-based authentication technology.
- Traditional authentication methods like SMS OTPs are increasingly vulnerable to cyber threats.
- SIM swap fraud incidents have exploded, with over 1,000% increase in the UK alone.
- Unibeam offers a hardware-rooted, deterministic authentication model for enhanced security.
- The global passwordless authentication market is set to grow significantly by 2030.
