Exposure is about reach: who can get the information, how easily and whether you expected them to have it.
Why it matters
Old addresses, phone numbers, relatives and workplace details can make phishing and impersonation more believable. Exposure does not always mean a breach; information can be legally public and still create risk.
What you can do
Start with the information that is easiest to find and most useful to an attacker. Update account settings, remove unnecessary listings and revisit the search because exposed information can return.
