Trust centre

Threat model

The model targets unauthorized local access, loss of a factor, and a compromised trust relationship.

What the model targets

Unauthorized local access

Someone in front of an unattended machine, trying to use the keyboard and mouse.

Loss of a factor

A lost phone, a misplaced security key, or unavailable recovery media.

Compromised trust relationship

A paired device that changes hands and must be suspended or revoked immediately.

What the model does not cover

Naming these limits is part of the product.

Administrator-level attacker

An adversary who already holds administrator privileges, or prolonged physical access to the hardware, is outside this scope.

Malicious software

ScreenShield21 does not scan files and does not replace an antivirus or anti-malware product.

General network traffic

It is not a VPN and it does not protect your browsing.

ScreenShield21 reduces identified risks. It promises neither total security nor protection against every attack.
