Our focus
We cover HUMINT service providers, corporate human intelligence and assignments combining human reporting with open-source research. Our guides explain how to assess source knowledge, corroboration and the limits of a finding.
How comparisons are prepared
Provider profiles use official service descriptions and relevant first-party methodology sources. Each comparison has a defined assignment scope. Inclusion notes explain the fit and the questions to confirm with the proposed team.
Who delivers an assignment
The named companies are external providers. An engagement, quote, permissions and delivery arrangements are agreed directly with the provider. The guide does not perform source collection for a reader.
Explore the evidence
Use the source links in each profile and read our methodology. Our HUMINT guides help you evaluate the proposal and findings.
