What Passguard is
Passguard is a European dark web monitoring platform focused on infostealer intelligence for businesses. It monitors criminal marketplaces for infected devices and stolen sessions connected to verified customer domains and other assets. The platform displays infections, traces, target lists, cracked passwords, breaches, and leaks, with alerts and reports supporting investigation workflows. Passguard says it checks whether stolen access remains active and can revoke it before abuse. Monitoring starts after assets are verified, without an agent or access to customer systems. A REST API provides thirteen endpoints per domain for SIEM, SOAR, and product integrations, while a mock server supplies synthetic data for development. The company says data is hosted in the European Union, it never pays cybercriminals, and it is GDPR compliant; ISO 27001 certification is in progress. A free quick scan needs no signup, while full trials use a team-led proof of concept.

Who it suits

Verdict
