STEGA TRUST
    Product

    The architecture that makes spoofing instantly detectable

    Cryptographic certification aligned with European standards, built into your daily Microsoft 365 workflow.

    How it works

    Three steps, one certainty

    The user experience stays exactly like Outlook. Trust, however, is transformed.

    You write

    Write your email as usual in Outlook. No interface change, no slowdown.

    STEGA TRUST certifies

    In the background, STEGA TRUST generates a unique, timestamped proof of identity. Your content never leaves your device.

    The recipient verifies

    A certification badge appears in your recipient's Outlook, or they can verify in one click at stegatrust.com/verifier.

    Microsoft 365 integration

    Native in Outlook

    10-minute setup via Microsoft AppSource. No changes to your email infrastructure.

    Local computation, zero content transmitted

    The fingerprint is computed on the user's device.

    Detailed use cases

    Before and after STEGA TRUST

    Bank detail fraud
    Before

    A fake email swaps bank details at the last minute.

    With STEGA TRUST

    The genuine sender is certified, the impersonator is not.

    Dispute over a written instruction
    Before

    A disputed email is evidence with no clear probative value.

    With STEGA TRUST

    Qualified eIDAS timestamp associated with each email, available if proof is needed.

    Corporate identity theft
    Before

    An attacker perfectly imitates your signature and style.

    With STEGA TRUST

    The absence of the STEGA TRUST badge exposes the fraud immediately.

    Regulatory compliance
    Before

    Hard to demonstrate technical cryptographic measures.

    With STEGA TRUST

    Documented, auditable trace of the security measures applied to email communications.

    The essential answers

    By applying a cryptographic signature to every email sent, combined with a qualified eIDAS timestamp issued by a qualified trust service provider (QTSP). The recipient can then verify that the message really comes from you.
