FAQ

What does Link Shield actually check when a URL is scanned?
Link Shield evaluates the URL itself, looks for suspicious patterns, reviews redirect behavior when a link tries to hide its destination, and returns a risk score with reasoning so your team can understand why a link looks safe, questionable, or high risk.
Is this only for phishing links?
No. Phishing is one of the most common use cases, but teams also use Link Shield to catch malware, scams, spammy destinations, risky adult or gambling links, suspicious crypto pages, and other traffic they do not want flowing through their product. This is especially helpful if users can submit or share links inside your app.
Do you follow redirects and short links?
Yes. Redirect-aware scanning is one of the biggest reasons teams use Link Shield. If a short link or redirect chain is trying to hide the final destination, the scan can surface that behavior so you are not making a decision on the first URL alone.
What does the risk score mean?
Each scan returns a score from 0 to 100. Lower scores generally indicate less suspicious behavior, while higher scores suggest stronger warning signals. Most teams use that score alongside the reason text to decide whether they want to allow a link silently, show a warning, queue it for review, or block it outright.
