Human-source evidence
We look for explicit references to source enquiries, interviews, human-source networks or comparable direct human collection. The presence of an analyst, an intelligence label or OSINT capability alone does not establish the relevant human-source method.
Assignment-specific inclusion
The general comparison covers a wider human-intelligence brief. Corporate HUMINT focuses on a business commissioner and professional source enquiries. The combined comparison requires both OSINT and human-source methods, with integration of the findings.
Reading the profiles
A profile distinguishes published capability from a hypothetical commissioning scenario. Requested outputs are proposals to discuss, not standard packages promised by the company. Confirm the people assigned, source access, jurisdictions and scope before engagement.
Sources and updates
Provider capability sources were reviewed on 19 October 2026. Official descriptions can change. Follow the linked source and confirm current availability with the provider. We use no invented customer reviews, performance scores, prices or delivery guarantees.
What a position means
The numbered presentation helps readers navigate the shortlist. Evaluate the stated fit and evidence against your own requirement. No single provider is appropriate for every source environment or question.
