Sensor-led exploitation intelligence

Your early warning for vulnerabilities moving into active exploitation.

Previdian uses proprietary sensors and private honeypots to surface exploitation early, then corroborates it with vendor advisories and public evidence. Watch the products you run and act sooner with evidence your team can verify.

Previdian Watch

Early warning for the products you run

Choose the vendors, products, and CVEs that matter to your team. Previdian watches for new exploitation evidence, sensor activity, proof-of-concept releases, and important status changes, then sends the warning through the channels you configure.

Priority is a rolling, personalized queue of new Watch signals that need review. It keeps the last 14 days of relevant activity in one place so your team can see what changed and what needs attention.

Intelligence system

How exploitation signals become trusted warnings

Previdian observes exploitation through proprietary sensors and private honeypots, corroborates signals against vendor advisories and public evidence, and keeps the evidence chain attached as warnings move into operational workflows.

Review methodology Compare with CISA KEV
  1. 01

    Observe

    Proprietary sensors and private honeypots surface exploitation activity, supported by vendor advisories and relevant public evidence.

  2. 02

    Attest

    Evaluate source credibility, specificity, corroboration, and available first-party telemetry.

  3. 03

    Enrich

    Add EPSS, CVSS, CWE, affected-version context, PoCs, Nuclei, Metasploit, and virtual-patch context.

  4. 04

    Deliver

    Send trusted warnings through the live feed, Watch notifications, RSS, JSON, and Pro API.

  5. 188 KEVs observed in sensors (7d)

    Evidence remains inspectable at every stage
