The Lumen Index reviews public reporting tied to the accounts you monitor, including workforce changes, breaches, vulnerabilities, leadership changes, and restructuring. The goal is to add an enriching layer of external intelligence across the portfolio.

How public reporting is handled

  • Collect: gather relevant public reporting tied to customer accounts in scope
  • Verify: check company identity and source quality
  • Review: apply one consistent evidence process across accounts
  • Return: highlight the accounts or cohorts that may deserve a closer look

Not every review item carries the same weight. Read how review strength is handled.

How to read coverage

Coverage reflects the accounts in scope, not the whole market.

The goal is not a complete census. The goal is a disciplined review process across the accounts you want reviewed.

Quiet accounts should not be treated as proof that nothing is changing.

Common review inputs

Different kinds of public reporting can matter differently in a customer portfolio review. The goal is comparable context, not a single event-by-event verdict.

Breaches

Active

Typical inputs

  • Publicly disclosed security incidents
  • Breach notifications and regulatory disclosures
  • Credible reporting of confirmed security events
