Proof of who's asking, at the moment it matters.
We provide cryptographic proof that every call, meeting, and message genuinely originated from the claimed person, on an approved device, at the moment a high-risk action is requested.
Every login control can work and the money still leaves.
Attackers impersonate colleagues, IT support, and suppliers to trigger the actions your controls never question: credential resets, payment approvals, vendor bank changes.

is where every one of these attacks succeeds.
Detection tools estimate whether something looks fake. As AI improves, the estimate gets worse.
Voice analysis, metadata signals, and behavioural AI all return a probability. Generative AI is trained to beat probabilities. Cryptographic proof does not degrade: identity is bound to a device in the person's hand, and verification returns a yes or a no. There is no model in the middle to fool.

Real-time verification across email, calls, text and video
Verify the sender before approving payments or taking urgent actions. "Your CEO" requesting an emergency transfer is actually your CEO.
Calls
Verify who is on the line before sensitive conversations begin. Cryptographic verification replaces knowledge-based questions.
Video meetings
Confirm everyone on the call is who they claim before discussing anything confidential. Deepfakes meet a check they cannot pass.
Messaging & SMS
High-risk requests carry proof or they escalate. Phishing disguised as routine messages stops working.
