Post-Quantum Cryptography

Future-proof your applications with quantum-resistant security. Multifactor's post-quantum cryptographic solution provides a robust foundation for secure application development, using algorithms specifically designed to withstand attacks from both classical and quantum computers, ensuring your data remains protected in the quantum era.

Build a foundation for the future

Multifactor enables applications to be built with quantum-resistant security from the ground up, providing robust end-to-end protection through verifiable enforcement of post-quantum authentication, authorization, and auditing policies that withstand both classical and quantum attacks.

Production-Grade Authentication
Multifactor provides a comprehensive authentication solution that directly binds data to a wide range of authentication methods, including biometrics, hardware tokens, and more.
Robust Authorization
Our quantum-resistant authorization enforcement is designed to meet the unique requirements of each application, ensuring that only authorized principals can access sensitive data and features.
Durable Auditing
Multifactor's auditing capabilities provide a comprehensive and indelible record of access and actions taken on sensitive data, ensuring compliance with regulations and standards.

Quantum-resistant, user-friendly security

We understand that post-quantum security solutions must remain user-centric and low-friction. Our quantum-resistant algorithms are designed for the gold standard of user indistinguishability, meaning that applications become protected against quantum attacks while users notice no difference at all.

Unlike other platforms, Multifactor's solution seamlessly integrates with existing authentication factors, ensuring that the transition to quantum-resistant security requires no changes to user workflows or familiar authentication methods.

Quantum-safe enforcement of complex policies

In the approaching quantum era, complex organizational policies and compliance requirements demand robust enforcement using cryptographic algorithms that can withstand quantum computer attacks on current encryption standards.

Multifactor's post-quantum technology suite uniquely enables trustless enforcement across authentication, authorization, and auditing using quantum-resistant algorithms, transforming vulnerable classical cryptography into strong, future-proof guarantees.

Quantum-safe resource sharing

Existing account sharing solutions are often irrevocable, untraceable, and backed by weak password-based cryptography. It's no wonder that major password management solutions have dozens of publicly confirmed data breaches!

Multifactor's quantum-safe technology uniquely enables online resources to be shared by multiple users in a way that is immediately revocable, non-repudiable, and fine-grained, without requiring any changes to the underlying application being shared.

We're preparing for the quantum future — so you can protect your application against tomorrow's threats today.

Quantum computers will break today's encryption, making current security measures obsolete. Multifactor's post-quantum cryptographic solution uses quantum-resistant algorithms that remain secure against both classical and quantum attacks, ensuring your applications are protected now and in the quantum era.
