Before you click: a smarter way to check suspicious links
What link reputation tools can tell you, what they cannot, and how to avoid exposing private URLs.
The first check happens before the scanner
Treat an unexpected link as untrusted, even when it appears to come from a familiar person or service. Inspect the sender, the context and the destination without opening it. A known brand name in a message is not proof that the destination belongs to that brand.
If a link relates to a bank, employer or account, open the organization's known address yourself instead of following the message. When in doubt, verify with the sender using a separate, trusted channel.
Use reputation tools with care
VirusTotal can help investigate publicly shareable suspicious URLs. urlscan.io can inspect a page and its network behavior, but scan visibility matters: public scans are discoverable, and unlisted scans may still be accessible to security researchers. Do not submit password-reset links, patient portals, private documents or sensitive tracking URLs to public scanning tools.
A clean result only means the scanner did not detect a problem at that moment. New threats, targeted pages and content that changes after scanning can evade reputation checks. A warning is useful evidence; the absence of one is not a guarantee.
A repeatable decision process
Use a simple process: identify the purpose of the message, compare the stated sender with a verified contact, inspect the actual destination, consider what data the site asks for, and choose the official website when possible.
For business links, ask your security team before uploading private URLs to outside services. Keep suspicious messages for investigation instead of forwarding them casually to colleagues.
