Cryptographic Identity Infrastructure

The missing layer between authentication and authorization

Authentication confirms you have a credential; cryptographic identity confirms you are who you say you are. Most vendors stop there.

Proof builds the infrastructure for what comes next.

Why authentication alone isn’t enough

Authentication answers one question: does this person have the right credential? At account recovery, workforce onboarding, and high-stakes financial authorization, the credential is gone, compromised, or not yet issued, leaving a question most identity stacks were never built to answer: is this person actually who they claim to be? Proof builds the infrastructure that does.

Most vendors run a check. Proof issues a credential.

A check answers a question at a single moment and expires when circumstances change. It cannot be referenced by other systems without re-running the underlying verification, carries no cryptographic weight, and provides no formal basis for a downstream authorization or regulatory inquiry.

A credential is categorically different: a digitally signed, tamper-evident record that persists, is independently verifiable by any party at any future time, and carries the formal weight of the certificate authority that issued it.

Proof is a WebTrust-audited certificate authority and listed on the Adobe Approved Trust List (AATL): two separate trust hierarchies, both independently audited, governing HTTPS certificate authorities and legally binding digital signatures respectively.

Confirm the person

Government-issued ID validation and liveness detection, grounded in who shows up, not just what they claim.

Built for the moments authentication doesn’t handle

Cryptographic identity infrastructure is the foundation beneath every moment where enterprise access carries real risk, across workforce identity and high-stakes financial authorization.

Enterprise Identity

From hire to offboard, every identity decision is made with proof.

Workforce identity spans the full employee lifecycle: verifying candidates before day one, securing account recovery, and revoking access at offboard. Cryptographic identity infrastructure makes each decision verifiable, auditable, and tamper-evident.

Agentic Identity

Verify the person who authorized the transaction, beyond the session token.

Wire transfers, account authorizations, and significant fund movements require more than a credential check: they require proof that a verified human initiated the action. Cryptographic identity infrastructure provides that layer, so the identity behind the transaction is as verifiable as the transaction itself.
