Passguard vs ZeroFox Dark Web Intelligence

Passguard is a web and API platform for monitoring infostealer activity connected to company domains and other verified assets. It looks for infected devices and stolen sessions on criminal marketplaces, then checks whether stolen access is still active; the company says it revokes active access before it can be abused. The platform presents infections, traces, target lists, cracked passwords, breaches and leaks, with alerts and reports for investigations. Monitoring begins after assets are verified, with no agent installation or access to customer systems required, according to Passguard. Its REST API offers thirteen endpoints per domain for SIEM, SOAR or product integrations, and a mock server provides synthetic data for development without a key. Passguard says customer data is hosted in the European Union on European infrastructure, it is GDPR compliant, and it never pays cybercriminals for data; ISO 27001 certification is in progress. There is no free plan, but a quick scan is available without signup and a team-led proof of concept can use a customer's assets. The Essential plan costs €250 a month on an annual contract, excluding VAT. API access is listed at €1,500 a month.
