Business email on your own domain, like the mailbox you use today, except that between IRON ID users the sender is a verified person and an attachment keeps its proof.

Like your professional mailbox, with the sender and the attachment vouched for.

Why Argon?

ArgonAr · atomic number 18

Argon is the gas archives use to preserve founding documents: it surrounds them and lets nothing alter them. The element that preserves names the email that keeps what was sent as it was sent.

What is IRON ID Argon?

Business email for your organization, on your domain.

Argon gives every member a professional mailbox and every team a shared one, on the IRON ID domain or on your own. It is part of the same organization as Silicon and Xenon: same accounts, same MFA, same roles.

What makes it different is who a message comes from. Between IRON ID organizations, the sender is a verified identity, and an attachment sent from Xenon keeps its fingerprint.

Attachments

A copy is not the document.

Every attachment is a copy. A document attached from Xenon carries its fingerprint, so the recipient can check it is exactly the version that was approved.
