Email encryption

Protect your emails with advanced encryption

encryption

Mailock uses military-grade encryption to keep your sensitive information safe from unauthorised access.

AES-256 encryption

Your emails are protected with AES-256 ciphers - one of the strongest security methods used to protect critical data.

Unique encryption keys

Each email is protected with its own unique encryption key, so if one message is ever compromised, the rest remain secure.

Enterprise-level security

For enterprise use, Mailock provides a secure, easy-to-implement API key for the Mailock Secure Email Gateway.

This makes sure all communication between your systems and Mailock is encrypted and authenticated, providing robust protection.

Multi-factor authentication

Encryption is just the start - Mailock also confirms the recipient’s identity before they can access encrypted emails, adding an extra layer of protection.

Encrypted connections

All interactions with Mailock - whether on the website or through the API - are encrypted to make sure connections remain secure.
