Provable Security for Web3

Web3 and blockchain companies face unprecedented security challenges in protecting digital assets and decentralized infrastructure. Multifactor offers a zero-trust solution that mathematically guarantees the integrity and confidentiality of crypto assets, smart contracts, and DeFi protocols while ensuring compliance in an evolving regulatory landscape.

Our history of Web3 security leadership:

Unique Identification of 50,000+ Virtual Reality Users from Head & Hand Motion Data

The challenge

Crypto turns a security problem into a key management problem.

Custodial key management degrades the inherent decentralized trust model of Web3, yet users are notoriously bad at managing their own keys.

Our solution

Multifactor's technology combines the usability of custodial key management with the security of self-custody, resulting in a secure experience that users measurably prefer according to a number of objective and subjective metrics.

Every transaction verified

Multifactor enables Web3 and blockchain organizations to safeguard access to digital assets, smart contracts, decentralized applications, and other sensitive crypto infrastructure through verifiable enforcement of advanced authentication, authorization, and auditing policies.

Trustless Authentication
Multifactor provides a comprehensive authentication solution that directly binds digital assets to a wide range of authentication methods, including hardware, biometrics, and traditional factors.
Robust Authorization
Our flexible authorization enforcement is designed to meet the stringent requirements of crypto organizations, ensuring that only authorized identities can access wallets, contracts, and protocols.
Immutable Auditing
Multifactor's auditing capabilities provide a comprehensive and cryptographically verifiable record of access and transactions, ensuring compliance with crypto regulations and standards.

Fast, flexible, and usable security

We understand that good security solutions are user-centric, and that ease of adoption is paramount in the fast-moving Web3 industry. We aim for the gold standard of indistinguishability, meaning that crypto applications become meaningfully harder to attack while users notice no difference at all.

Unlike other platforms, Multifactor's authentication solution is fully compatible with existing Web3 infrastructure including hardware wallets and other common crypto authentication methods, ensuring that users don't have to learn new technologies and can continue to use tools they trust.

Simple enforcement of complex policies

Between managing multi-signature wallets, complex smart contract permissions, and the need to protect digital assets across multiple blockchains, Web3 demands robust enforcement of sophisticated 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 that complement blockchain's inherent security model.

Share crypto resources securely

Existing crypto asset sharing solutions are often irrevocable, untraceable, and vulnerable to private key compromise. It's no wonder that billions in crypto assets are lost to security breaches and insider threats every year!

Multifactor's technology uniquely enables digital assets and DeFi protocols to be accessed by multiple users in a way that is immediately revocable, cryptographically auditable, and fine-grained, without requiring any changes to the underlying smart contracts or blockchain infrastructure.

We're redefining zero-trust — so you can protect every wallet, smart contract, and digital asset.

Identity is your first and last line of defense in Web3, and the root cause of most crypto security breaches. Multifactor's provably secure zero-trust solution cryptographically guarantees that only authorized users can access digital assets and DeFi protocols, turning identity into your greatest asset in the fight against crypto threats.
