Human knowledge.
Assessed with care.

Compare providers for a human-source assignment: the relevant people, the question they can help answer and the evidence needed to assess their accounts.

Define the gap

Specify what people may know that the available records do not explain. Name the decision and the material question.

Test the account

Ask how direct knowledge, source interests, independent corroboration and contradictory information are assessed.

Keep the limits visible

Request findings that distinguish source reporting, documented facts and analysis, including what remains unknown.

01

Molfar Intelligence

Source enquiries tied to verifiable business questions

Official capability ↗

Molfar explicitly offers human-source enquiries alongside documentary investigation. Its HUMINT guidance treats interview reporting as information to assess and corroborate, which is a useful basis for a narrowly defined brief. Consider it when records establish the people and events but do not explain an operational change or disputed relationship. Ask how source access, contradictions and remaining uncertainty will be documented before relying on the assessment.

A situation to scope

Hypothetical brief: A UK buyer sees a supplier's service deteriorate despite unchanged corporate filings. Request an investigation into the stated explanation, using appropriately scoped conversations with knowledgeable people and available records. The objective is to identify supported causes and unanswered questions before the buyer renews a business-critical contract.

02

Next Sight

A dedicated HUMINT engagement with defined handling

Official capability ↗

Next Sight describes a dedicated HUMINT service covering interviews, source assessment and verification against open sources. This makes it a candidate when the client wants the human collection component made explicit in the proposal. Compare the planned source categories, permitted contact and report handling, rather than assuming every intelligence package includes interviews. Request an explanation of what would cause collection to stop or the finding to remain unconfirmed.

A situation to scope

Hypothetical brief: A corporate security team receives inconsistent accounts of an overseas site's operational readiness. Ask for a bounded human-source brief focused on the remaining questions, with agreed contact limits and checks against available documentation. The final assessment should explain which accounts rest on direct knowledge and which remain second-hand.

03

S-RM

Human-source research within an integrity review

Official capability ↗

S-RM's diligence service expressly combines open-source research with a human-source network. This fits a buyer who wants contextual information integrated into an existing integrity review, rather than delivered as unqualified interview commentary. Ask the team to explain why the proposed contacts can answer the actual question and how independent their accounts are. The value of several interviews depends on their evidential relationship, not simply the number completed.

A situation to scope

Hypothetical brief: An investor hears conflicting accounts of a potential partner's management conduct from several introductions. Commission a focused review of the relevant events and source access, alongside the existing research. The output should distinguish independent first-hand accounts from repeated market rumours before the investor chooses its next diligence step.

04

Control Risks

Business questions requiring locally informed source enquiries

Official capability ↗

Control Risks' official practice evidence describes human intelligence-led work and local source enquiries, while its deals service combines human information with analysis. This is relevant where understanding a commercial relationship requires contextual knowledge absent from formal records. Scope the actual countries and source access, because a broad international practice does not establish feasibility for every location. Ask for differences between local opinion, direct observation and independently supported findings.

A situation to scope

Hypothetical brief: A company considering a local partnership needs to understand why a prospective partner repeatedly changes project arrangements. Request enquiries into the relevant business history and local context, checked against documentary events. The client needs a qualified account of the relationships that could affect the proposed commitment.

05

Kroll

Qualitative source intelligence for consequential decisions

Official capability ↗

Kroll's investigative diligence service explicitly draws on human sources for qualitative and contextual research. Its culture-check offering provides a more specific example of interview-based collection. This makes it relevant when the commissioning team needs an account of behaviour or relationships that company records cannot establish. Ask whether the engagement requires interviews, records work or both, and how the team will prevent an unsupported source account from becoming a categorical conclusion.

A situation to scope

Hypothetical brief: A lender is concerned that the public account of a borrower's leadership history omits significant events. Commission targeted research and relevant source enquiries into the defined period. The report should connect any material account to the person's actual role, corroborating evidence and remaining verification needs.

K2 Integrity

Established networks and contacts identified for the project

Official capability ↗

K2 Integrity explicitly offers human-source enquiries and describes both existing contacts and sources identified for a particular investigation. That distinction is useful when comparing whether a team can answer a niche question through relevant experience rather than general access claims. Ask how contact categories will be chosen, how competing accounts will be evaluated and where records can test the resulting leads. Commission specific questions rather than an unrestricted investigation of a person.

A situation to scope

Hypothetical brief: An investment team cannot explain a target company's abrupt change of business strategy from its disclosures. Request a bounded review of the decision period through relevant records and appropriately selected industry contacts. The output should separate direct knowledge of the change from inference about its motives.

Investigative research drawing on records and human contacts

07

Risk Advisory

Targeted enquiries to resolve a diligence gap

Official capability ↗

Risk Advisory publishes explicit human-source work within its diligence offering. It is a candidate when the client has a clear unresolved question and needs targeted contextual enquiries rather than a general information-gathering exercise. Define the claim to test and what would count as meaningful corroboration. Request visibility of the source's relationship to the issue and any uncertainty that prevents the resulting account from resolving the client's concern.

A situation to scope

Hypothetical brief: A financial institution has documents supporting a client's business ownership but an incomplete explanation of a key business sale. Ask for focused contextual enquiries against that event and the evidence already held. The team should identify what is corroborated and which private documents remain necessary.

Diligence service and human-source examples ↗

Question-specific human-source diligence

08

Diligencia

Human enquiries around difficult regional records

Official capability ↗

Diligencia explicitly combines human-source enquiries with official-record research and states a Middle East and Africa focus. It is relevant when a regional company's formal records leave an important relationship or operating claim unexplained. Check the exact locations and proposed sources before commissioning. The useful output is a qualified explanation supported by available evidence, with a distinction between what a record establishes and what a knowledgeable contact can add.

A situation to scope

Hypothetical brief: A UK supplier is considering a distributor whose regional corporate records show little recent activity. Request research into the company's actual operating background, using relevant official material and appropriately scoped local enquiries. The resulting brief should explain the evidence gaps without equating limited public visibility with misconduct.

Regional human-source enquiries with official-record research

09

Wallbrook

Interview-led context beyond formal company records

Official capability ↗

Wallbrook explicitly identifies HUMINT interviews alongside difficult-to-access record research. That is relevant when a polished corporate presentation leaves questions about practical influence or a principal's conduct. Ask what the interviews are intended to establish and how factual assertions will be tested. A useful commission should identify which decisions could change in response to the findings, keeping interesting but immaterial background commentary outside the core report.

A situation to scope

Hypothetical brief: A private investor is assessing a principal whose public biography gives little insight into earlier business relationships. Commission targeted contextual research into the relationships relevant to the proposed venture. Any source commentary should be assessed for direct knowledge and checked against available documentary history.

Nardello & Co.

Human interviews within a defined corporate investigation

Official capability ↗

Nardello's investigation service expressly includes employee interviews and enquiries with knowledgeable industry sources. It fits situations where human reporting is part of a broader factual investigation, especially when internal records raise questions requiring explanation. Agree who may be approached and which events matter. The briefing should keep a witness account, an investigator's assessment and documentary findings distinguishable so the client can understand the evidential basis for further action.

A situation to scope

Hypothetical brief: A company receives an allegation that staff and an external supplier coordinated unusual procurement decisions. Request a scoped review of authorised records and relevant interviews about the identified events. The objective is to establish supported facts and determine what needs further investigation, without assuming the allegation is true.

Investigation methods ↗

Human enquiries within a broader corporate investigation

What should the assignment deliver?

Agree deliverables that answer the question rather than assuming every provider supplies the same package.

Ask for an evidence-led output.

These are briefing requirements to discuss, not standard packages guaranteed by every provider.

  • A scoped question and approved source-enquiry plan.
  • Source context, direct knowledge and relevant dates.
  • Corroboration, contradictions and alternative explanations.
  • Findings, limitations and specific next evidence needs.

Scope and permissions

Identify subjects, roles, countries, contact boundaries and recipients.

Collection and review

Assess relevant human accounts against the defined question and other available evidence.

Assessment and handover

Separate supported findings from reported claims and explain the remaining uncertainty.

Three situations. Different evidence needs.

Illustrative commissioning scenarios, with outputs to agree before work begins.

A question records leave open

Ask people with relevant knowledge to explain the scoped event or relationship.

Ask for: A source-assessed account and corroborating evidence.

Contradictory explanations

Establish who knew what, at which date, and how separate accounts relate.

Ask for: A comparison of accounts, records and remaining gaps.

A local context gap

Confirm the specific regional access and language capability the assignment needs.

Ask for: A qualified account of local knowledge and its source limits.

Plan the work before the quote.

Delivery depends on the actual source access, mandate and verification required.

What affects timing?

  • Source availability and the relevant historical period.
  • Countries, language capability and contact approvals.
  • The records needed to test important claims.
  • Whether an interim finding can support the decision.

What affects cost?

  • Number and complexity of the questions.
  • Specialist personnel and local research needs.
  • Collection, corroboration and reporting depth.
  • Approved expansion beyond the first phase.

Request a scoped proposal, reporting milestones and approval for additional work. This guide does not publish assumed provider rates or delivery guarantees.

Choose the right HUMINT route.

What Is HUMINT? Human Intelligence for Business Decisions

HUMINT means human intelligence: information obtained from people and assessed against a defined question. In a business assignment, the value is the relevant knowledge a source can contribute and how carefully that account is tested.

How to Choose a Commercial HUMINT Agency

Select a team for the human-source question you need answered. Ask who will conduct the work, how accounts will be evaluated and what the report can responsibly establish.

HUMINT Services Cost: Scoping and Comparing Proposals

A meaningful cost comparison starts with the human question, approved methods and report. Separate source enquiries, corroboration and optional follow-up before comparing commitments.

Read the guide ↗

What Should a Commercial HUMINT Report Contain?

A useful HUMINT report explains what people said, how their knowledge relates to the question and what the evidence supports. A source account should never become an unqualified fact by losing its context.

HUMINT Source Validation: Assessing Accounts and Corroboration

Source validation should explain why a particular account deserves weight and where uncertainty remains. It is a structured assessment of evidence, not a guarantee that a person or every statement is reliable.

Confidentiality in HUMINT services: what to agree before work starts

Confidentiality in a HUMINT assignment concerns the client’s brief, source identities, collected personal information and the assessment itself. These need clear controls and realistic commitments, rather than an unexplained promise of total secrecy.

Questions worth asking.

Define the requirement, assess the evidence and understand what a provider can realistically deliver.

How do I compare HUMINT service providers when I have not commissioned human intelligence before?

Start with the decision, knowledge gap, relevant roles and permitted sources. Compare proposed personnel, source access, corroboration and reporting against the same brief. Use the provider profiles to ask concrete questions rather than assume every advertised capability will be used.

Does a provider need a separate HUMINT department to deliver a human-source assignment?

A department label is less useful than evidence of relevant people, methods and source enquiries. Ask who will perform the work, how information is evaluated and who integrates it with other evidence. Confirm the actual assigned team and mandate.

Can I use a HUMINT report as proof that every source statement is accurate?

Review the statement, source access, corroboration and qualifications. A report should distinguish what a person said from an established fact or assessment. Incomplete access and conflicting accounts should remain visible.

How can I commission human intelligence without turning the brief into an unlimited investigation?

Name the question, relevant people, dates and scope boundaries. Agree contact permissions, first-phase outputs and approval for additional work. A new lead should be assessed for relevance before it expands the assignment.

Should I choose a combined OSINT and HUMINT provider if my records are already complete?

That depends on the unanswered question. Records may establish events while leaving experience or context unclear. Explain the gap and ask which human enquiries could materially help; do not add another evidence stream merely to increase the report’s size.

What should I do if the initial HUMINT phase cannot reach a reliable conclusion?

Request the coverage, unresolved propositions and evidence that could change the assessment. A qualified finding can still inform a decision. Agree whether a narrow follow-up is justified rather than treating further collection as automatic.

A better brief starts with
the right question.
