Secure, scalable, and transparent security

We understand that effective AI security solutions must be user-centric and that accessible solutions are paramount in the AI safety industry. We aim for the gold standard of indistinguishability, meaning that AI systems become meaningfully harder to attack while researchers and users notice no difference in model performance or system usability.

Unlike other platforms, Multifactor's authentication solution is fully backward compatible with existing AI infrastructure, frameworks, and commonly used authentication factors, ensuring that users don't have to learn new technologies and can continue to use tools they are familiar with while maintaining rigorous security standards.

Robust enforcement of AI safety policies

Between managing model governance, ensuring responsible AI deployment, complex organizational policies, and the need to protect sensitive training data, AI safety demands robust enforcement of sophisticated security policies across the entire machine learning pipeline.

Multifactor's technology suite uniquely enables trustless enforcement across authentication, authorization, and auditing for AI systems, transforming typically weak, software-defined enforcement into strong, cryptographically backed guarantees that protect models, data, and inference systems.

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 or agents 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 every model, dataset, and agent.

Identity is your first and last line of defense in AI systems, and the root cause of most AI security breaches. Multifactor's provably secure zero-trust solution cryptographically guarantees that only authorized agents can access sensitive models and training data, turning identity into your greatest asset in the fight against adversarial attacks and unauthorized AI access.
