What Passguard is
Passguard is a European web and API platform for monitoring infostealer activity linked to company domains and other verified assets. It monitors criminal marketplaces for infected devices and stolen sessions, then checks whether stolen access remains active and says it can revoke that access before misuse. The platform displays infections, traces, target lists, cracked passwords, breaches and leaks, with alerts and reports for investigation workflows. Monitoring begins after assets are verified, without an agent installation 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 integration work without a key. Passguard says customer data is hosted in the European Union, its service is GDPR compliant, and it never pays cybercriminals for data. Essential costs €250 a month on an annual contract, excluding VAT; higher plans and API access are also listed.
