Why Trust Unibeam’s SIM-Based Authentication?

Unibeam makes your accounts more secure by linking your device directly to your identity. This means no one can access your accounts without your device, protecting you from hacks, stolen credentials, and impersonation. Plus, our advanced encryption keeps your sensitive data safe every step of the way.

Unibeam keeps enterprises firmly in control of authentication, avoiding the risks of third-party outsourcing. With secure authentication vectors and user-answered pop-up questions, Unibeam enables safer, more deterministic decisions. This makes it ideal for organizations that need both top-tier security and full authority over authentication.

How Does Unibeam do SIM-Based Authentication? 

Unibeam makes sure your SIM/eSIM is securely linked to the phone number and device you use for online services. Here’s how:

⦁ Secure Binding – Unibeam identifies each device using two key details – a device ID (like its IMEI or a hardware-based cryptographic key) and a SIM ID (like its IMSI). During setup, these two IDs are securely linked to your mobile phone number, creating a trusted three-prong authentication stack.
⦁ Unbreakable Pairing – Unibeam locks each SIM or eSIM to its device. If a SIM is removed or cloned, this binding is broken – making fraudulent authentication impossible.
⦁ Ironclad Encryption – Your data is encrypted right at the source using unique technology built into the SIM. This keeps your data safe from interception or eavesdropping.
⦁ Bulletproof Data Integrity – All your data is protected from tampering or spoofing, ensuring it stays private, accurate, and secure.
⦁ Constant Vigilance – Unibeam enables enterprises to continuously monitor and detect unauthorized activity or spoofing in real time.

What Does Unibeam Secure?

Unibeam protects both your device data and the connection between the device and its SIM. We do this by securing:

⦁ Identifiers
When your Unibeam SIM or eSIM applet is activated, it creates two secure identifiers, both hashed using the SHA-3 algorithm to create a secure bond between the device and the SIM/eSIM:

⦁ SIM Identifier – A unique random number generated for the SIM or eSIM.
⦁ Device Identifier – A unique random number generated for the physical device.

Both identifiers are unique to each device and to each authentication service. No two Unibeam identifiers are alike, avoiding any collateral risk to enterprises if a protected service is compromised.

⦁ Communications
All communications between the Unibeam system and the SIM/eSIM applet utilize AES-derived encryption algorithms implemented directly on the eSIM/SIM cards for enhanced security.

Secure Code and Environment, and Standards Compliance

⦁ FIDO Certification – Unibeam is actively working to certify our authentication solution for Functional Certification and Certified Authenticator Level 2 (L2).
⦁ PII-Free Platform – We never store Personally Identifiable Information (PII). Authentication is done using anonymized, hashed identifiers, ensuring your data stays private and secure.
⦁ Secure Software Development Life Cycle (SSDL) – All our code is developed with secure coding practices from the start, following the SSDL framework.
⦁ Third-Party Audits – Our SDK code is reviewed and audited by a leading international security firm to ensure its security and reliability.
⦁ Penetration Testing (PT) – We partner with a trusted security firm to perform regular penetration tests. Any issues found are fixed immediately based on priority.
⦁ AWS Infrastructure Security – Our platform runs securely in AWS and uses top cloud security services to protect its infrastructure. We follow industry best practices, including:
⦁ AWS Foundational Security Best Practices
⦁ NIST 800-53 Rev 5 and NIST Cybersecurity Framework (CSF) v2.0
⦁ CIS AWS 3-Tier Web Architecture Benchmark v1.0.0
⦁ CIS Controls v8
⦁ CIS Controls v8
