# Passguard

> Passguard is a Dutch stealer intelligence platform founded in 2021, focused on detecting and responding to infostealer infections. The platform monitors criminal marketplaces and Telegram channels for compromised devices, stolen credentials, active sessions, and cookies — enabling security teams to spot infections early, revoke access, and prevent further misuse. Headquartered in Leusden, Netherlands.

Passguard serves organizations in energy, manufacturing, infrastructure, healthcare, and tech. Over 95% of infostealer attacks start on unmanaged devices — the blind spot EDR solutions cannot cover. Infostealers steal session tokens which attackers buy to bypass MFA and access internal systems. Passguard detects this by infiltrating the markets where stolen data is sold.

Key differentiators: no endpoint installation required, setup in under 2 minutes, EU-hosted data, zero false positives, real-time alerts on new infections, and unmatched criminal marketplace infiltration.

## How It Works

Passguard operates in three steps:

1. **Share your domains** — Select domains you want monitored. No system access needed.
2. **Marketplace monitoring** — Passguard identifies infected devices with active sessions in your systems across criminal marketplaces and Telegram channels.
3. **Alerting** — Get notified with actionable data: which sessions to revoke, which devices are compromised, malware type, OS, and infection timeline.

Data is organized into employee infections, user infections, and infection traces with global search for instant clarity.
