How to read this alert

Treat this as a signal to slow down and verify the destination, the request, and the audience. The alert does not mean every related page is malicious. It means there is enough risk that the normal click-through habit is not good enough.

The safest response is to separate the message from the account, service, or person it claims to represent. Open the real service from a bookmark, typed address, password manager, or trusted app instead of letting the suspicious page choose the path for you.

What to check before you trust it

The safety check could not load, classify, or inspect the destination.
The site blocked automated checks, timed out, or required a login.
A safety classifier or model was unavailable.
The link is shortened, redirected, or hidden behind a service the safety tool cannot evaluate.

Decision path

1. Name the request

Is the page asking for a login, payment, download, private context, automated action, or approval?

2. Check the evidence

Compare the actual destination, signal tags, sender, and page behavior against what you expected.

3. Choose the safer route

If the request is sensitive or surprising, leave the link and use a known-good path or trusted person.

Examples

RiskyA shortened link cannot be expanded by the checker, but the message asks you to sign in immediately.SaferUse a known-good path to the service instead of the shortened link.

RiskyA private document link requires login before the safety check can see its final page.SaferConfirm the sender and open from the official app or workspace.

What to do next

Do not treat an unreadable result as a clean result.
Open the service directly if the message relates to an account you use.
Ask the sender to resend through an expected channel when the link is surprising.
Wait and retry the safety check if the classifier or model was temporarily unavailable.

Common mistakes

Treating `not checked` as `safe`.
Assuming a link is fine because only the safety tool failed.
Opening a link manually without using ordinary caution.
