Deepinfo Dark Web Monitoring vs Passguard

Deepinfo Dark Web Monitoring tracks indexed dark-web sources for mentions of organizations, products, executives, internal codenames, and other chosen identifiers. It covers English-, Russian-, and Turkish-language forums, marketplaces, paste sites, leak sites, and chat channels. Alerts can go to email, Slack, SIEM, or ticketing systems, with frequency set by channel. On-demand searches can be filtered by identifier, source type, or time window, and include source attribution and mention context. False-positive feedback contributes to relevance scoring. The service can connect mentions with threat-actor profiles, map TTPs to MITRE ATT&CK, and add sector context. Its Data Breach Index supports direct searches and checks customer email lists against newly indexed breaches. Listed SIEM integrations include Splunk, Microsoft Sentinel, IBM QRadar, and Elastic Security; data is also available through REST APIs. Platforms are Android, iOS, web, and API. Pricing is on request, with scope and module mix affecting the price and asset count its biggest factor. An annual commitment is standard. There is no free plan; a free threat-exposure report and paid pilots scoped over 30 to 60 days are available.

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.
