What is the Zero Trust model?

Zero Trust security is an IT security model that requires strict identity verification for every person and device trying to access a resource. Zero trust is best known from network architectures but still it is a holistic approach. Secure-lines uses this approach and adds extra and extensive encryption layers. This enables secure lines to not only guarantee the identity of the persons communicating but also to trust the contents exchanged.

Secure lines trust nobody, not even ourselves. This is why not even we can access the data exchanged between secure lines and that’s how secure your most pressures keys and passwords are.

But be aware, if you loose your device not even we can recover your data.

What makes Secure Lines secure?

A short summary of the principal mechanism of Secure Lines

1. Clientside encryption
2. Encrypted (TLS) to a delegation server (TOTP) and encrypted again from the delegation server (TLS)
3. Clientside decryption
