Practical introductions to specialist investigative, intelligence and security disciplines.
Open-source intelligence turns publicly available information into assessed, attributable findings. Effective OSINT depends on a clear requirement, careful source evaluation and transparent reporting—not simply finding information online.
Read overview →Internet investigation combines searching, identity research, source evaluation, preservation and analysis to answer a defined investigative question. It may draw on open sources, client-held information and authorised specialist capability.
Read overview →Digital HUMINT applies human-intelligence principles to lawful online engagement, assessment and source-related activity. It requires judgement about people, motivation, risk, authority and welfare as well as technical competence.
Read overview →Darknet investigation focuses on hidden services, identifiers, infrastructure, behaviour and connections that may support intelligence or evidence. Safe access alone is not an investigative strategy.
Read overview →Cryptocurrency investigations examine transactions, wallets, services and associated online activity to understand movement, control and relationships. Blockchain visibility does not automatically reveal real-world identity.
Read overview →Digital evidence can support investigations, disciplinary matters, litigation and incident response when it is identified, preserved, examined and explained appropriately.
Read overview →Cyber incident response coordinates containment, evidence preservation, investigation, recovery and communication after suspected compromise or disruption.
Read overview →Protective intelligence identifies and assesses information relevant to potential harm against people, organisations, sites or events, then connects it to practical security decisions.
Read overview →Artificial intelligence can support research, organisation, analysis and drafting, but the investigator remains responsible for legality, verification, evidential integrity and professional judgement.
