Provable Web Security

Great web application security starts with robust identity management. Multifactor's provably secure zero-trust solution provides a strong cryptographic foundation for secure web development, mathematically guaranteeing that only authorized users can access sensitive data and functionality across browsers and devices.

A foundation for success

Multifactor enables web applications to be built from the ground up with security in mind, providing robust end-to-end security through verifiable enforcement of advanced authentication, authorization, and auditing policies tailored for the web.

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 flexible 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 web requests, user interactions, and data access patterns, ensuring compliance with web security regulations and standards.

Fast, flexible, and usable security

We understand that good web security solutions must be user-centric and low-friction, especially in browser environments where users expect seamless experiences. We aim for the gold standard of user indistinguishability, meaning that web applications become meaningfully harder to attack while users notice no difference in their browsing experience.

Unlike other web security platforms, Multifactor's authentication solution is fully backward compatible with existing web standards and commonly used factors such as passwords, WebAuthn, and browser-stored credentials, ensuring seamless integration with existing web workflows.

Simple enforcement of complex policies

Between juggling multiple compliance requirements, complex organizational policies, and the need to protect sensitive data, real-world applications demand robust enforcement of complex security policies.

Multifactor's technology suite uniquely enables trustless enforcement across authentication, authorization, and auditing, transforming typically weak, software-defined enforcement into strong, cryptographically backed guarantees.

Share resources effectively

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 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 redefining zero-trust — so you can protect your web applications with confidence.

Identity is your first and last line of defense in web applications, and the root cause of most web security breaches. Multifactor's provably secure zero-trust solution cryptographically guarantees that only authorized users can access sensitive web resources, turning browser-based identity into your greatest asset in the fight against web-based cyber threats.
