Why this isn’t just another breach checker

A breach leaks your credentials. Then hackers chain those credentials to your address, family, phone, and employer using public broker sites. We’re the only tool built around that chain.

Free checker Tells you the breach happened. End of story. You’re still on 800+ broker sites.
$129+/yr Broker-removal services scrub the address but don’t see the breach — next leak re-exposes you.
GalaxyWarden Maps the chain. Cleans both halves. $19 one-shot. Closed loop.
