Human intelligence, or HUMINT, is intelligence derived from information collected and provided by human sources. The US Department of Defense dictionary defines it this way. In cyber threat intelligence it means learning about threats through people, such as sources inside criminal communities, rather than only from technical data.

How does HUMINT work?
The US Department of Defense Dictionary of Military and Associated Terms defines human intelligence as a category of intelligence derived from information collected and provided by human sources. The source is a person, not a sensor or a log file.
In cyber threat intelligence, as a general illustration, a team may build relationships with people in closed criminal communities, talk directly with sellers on an underground forum, or speak with insiders and victims. Analysts then check what they hear against technical evidence.
How is it different from OSINT and technical intelligence?
Open source intelligence, or OSINT, uses publicly available information. Technical intelligence uses data such as malware samples, domains and network traces. HUMINT adds what people say and intend, which these other types often cannot show. For example, a conversation with a seller can reveal who plans to sell access to a company, and why, before any technical trace exists.
Why does it matter?
Technical data tells you what happened. People can tell you what is planned and why. HUMINT can add early warning and context to alerts, such as who is behind an offer and what they want. It also carries risk: sources can lie, and contact with criminals can raise legal and safety questions. Findings should be treated as claims to verify, not as facts.
How do you use it well?
- Check every claim against a second source, ideally technical.
- Record how reliable the source has been in the past.
- Follow your legal and ethical rules before any contact with a threat actor.
- Use a provider that does this work for you, if you do not have the team for it.
