Recipient authentication for secure email
Help ensure sensitive emails open only for the intended recipient. Add a recipient access check to reduce wrong-recipient risk, without creating unnecessary friction.
Inbox delivery to the right people
Mailock® encrypts every sensitive message.
Recipient authentication adds an extra layer of control by requiring an access check before the encrypted content can be opened, helping reduce wrong recipient access.
1. Compose
Send a secure email from Outlook or the Mailock web app, adding attachments if needed.
2. Encrypt
Mailock encrypts the email and attachments. You can send with encryption-only, or add an access check for extra control.
3. Challenge and access
If a challenge is applied, the recipient must complete it before they can open the encrypted message. If they can't pass the check, access is blocked.
Security & Compliance
Stronger access control for sensitive email
Recipient authentication controls who can open encrypted messages using email, SMS, or security-question access checks.
This extra access step helps reduce unauthorised disclosure risk and support expectations from regulators including the ICO and the FCA around protecting sensitive communications.
