Passguard detects infostealer infections before attackers sell your access on criminal marketplaces.
No agents. No installs. 

Infostealers bypass MFA. They infect unmanaged devices your EDR can’t see. We fix that.

We infiltrate criminal marketplaces ethically and at scale, so you get real-time alerts when your employees' devices and session tokens are compromised and being traded online.

Our unique approach:
🔹 Zero-Touch Deployment – No software or agents required
🔹 European-first Security – Dutch platform, EU-hosted data
🔹 Unmatched Visibility – See session info, malware type, and timeline in real time

Trusted by security leaders.

“Passguard is no-nonsense. Clear. Factual. The data tells the story.” – Bas Wevers, CISO

“Passguard gives us time to fix vulnerabilities before they’re exploited.” – Hans Quivooij, CISO

"We benchmarked all major providers. Passguard delivered the most complete data." - Rogier Fischer, CEO

Every day, Passguard monitors infostealer risks for hundreds of thousands of employees across three continents.

We just launched our Infostealer Quick Scan, a no-risk, no-install preview of infostealer exposure in your organisation.
