Jsmon Dark Web Monitoring vs Passguard

Jsmon Dark Web Monitoring monitors underground marketplaces, ransomware blogs, breach dumps, paste sites, and Telegram channels for exposed credentials, source code, infrastructure, and brand mentions. Its crawlers, bots, and scrapers ingest more than 100 sources, including forums, stealer log marketplaces, and code repository leaks. Users can set watchlists for domains, brands, executives, IP ranges, products, and code signatures. Jsmon says AI models match mentions, deduplicate findings, attribute actors, filter false matches, and add severity, source reputation, and blast-radius context; its stated median time from posting to alert is under four hours. Integrations include Slack, Teams, Jira, PagerDuty, and XSOAR, with API, webhooks, and SOAR playbooks for workflows. The service says exposed credentials are hashed and matched against watchlists, with raw passwords neither stored nor fully displayed. Collection is described as passive: it observes and indexes rather than purchasing data or interacting with threat actors. It lists support for several security and breach-awareness frameworks and regulations. A free Starter trial provides 1,500 lifetime credits and email alerts only; paid service starts at $15/mo (annual).

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.
