Why breach exposure matters
When a third-party service is breached, your email and password can end up in lists that attackers use for credential stuffing — trying that password everywhere you might reuse it. One old leak can quietly become an account takeover.
A one-off check is a good start, but exposure happens continuously. HookPhish data breach and dark web monitoring alert you the moment your credentials appear in a new breach, with guided steps to contain it.
