Fast, flexible, and usable security

We understand that good security solutions are user-centric, and that accessible solutions are paramount in the financial services industry. We aim for the gold standard of user indistinguishability, meaning that applications become meaningfully harder to attack while users notice no difference at all.

Unlike other platforms, Multifactor's authentication solution is fully backward compatible with existing, commonly used factors such as passwords, hardware tokens, and biometrics, ensuring that users don't have to learn new technologies and can continue to use factors they are familiar with.

Simple enforcement of complex policies

Between juggling multiple compliance requirements like SOX, PCI DSS, and Basel III, complex organizational policies, and the need to protect sensitive financial data, the finance industry demands 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 for financial institutions.

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 affecting financial institutions!

Multifactor's technology uniquely enables financial 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 trading platforms or banking applications being shared.
