Check first. Understand the warning. Then decide.

Suspicious message, link, or file? Check it before you continue.

Shield helps you assess suspicious content without making absolute promises. The new mobile Ghost Pairing check warns when a WhatsApp link is really trying to connect another device.

Ghost Pairing does not need your password

Attackers abuse WhatsApp’s legitimate linked-device feature. A fake photo, vote, or security page asks for your phone number, a linking code, or a QR scan. Shield detects these patterns and shows how to remove an unknown device.

What Shield does

Protection before and after the click

1

Links and messages

Check the domain, common scam wording, hidden destinations, and existing Shield reports.

2

Documents before opening

Office, PDF, and ZIP files are examined statically for technical warning signs without being executed.

3

Email and phone checks

Assess format, plausibility, and known Shield reports before you reply or call back.

4

CMC Sentinel on Windows

Understand processes and connections, block remote access, clean selected caches, and use prepared emergency actions.

5

Privacy by design

No background upload of browser history, process lists, or local Sentinel logs. Online checks start only when you request them.

Up to five household devices

Each Sentinel device is confirmed separately and can be revoked from the Shield account.
