Previdian

Previdian is a vulnerability exploitation intelligence service that records which CVEs are being exploited and attaches the supporting evidence to each record. It observes exploitation through proprietary sensors and private honeypots, and corroborates signals against vendor advisories and public evidence. Each signal is assessed for source credibility, specificity, corroboration, and available first-party telemetry. Records are then enriched with EPSS, CVSS, CWE, affected-version context, and practical artifacts such as PoCs, Nuclei templates, Metasploit modules, and virtual-patch context. Previdian publishes comparisons against the CISA KEV catalog, including cases where it recorded exploitation before CISA added the vulnerability and exploited vulnerabilities not in CISA's catalog. Records carry named timestamps and confidence levels. Previdian Watch lets users select vendors, products, and CVEs to monitor. It notifies them of new exploitation evidence, sensor activity, proof-of-concept releases, and status changes through configured channels. A Priority view keeps a rolling 14-day queue of relevant Watch signals for review. Warnings are delivered through a live feed, Watch notifications, RSS, JSON, Slack, and a Pro API. A 14-day Pro trial without a credit card is offered. The service was built by Ryan Dewhurst, creator of DVWA and founder of WPScan.
