Making stealer infections worthless.
Passguard is a European dark web monitoring platform specialised in infostealer intelligence.

- Find
We help hundreds of security teams find stolen credentials, active sessions and cookies from compromised devices.
- Test and revoke
Our technology tests whether stolen access is still active and revokes it before it can be abused.
- Built in Europe
We are built and hosted in Europe and never pay cybercriminals for data.

Specialists in intelligence, law enforcement and product.
We have tracked threat actors, built large-scale investigations and designed tools people actually use. Passguard combines that operational experience with technical depth.
Eight people, one problem to solve.
