OSINT resources: tools, search engines and practical guides
Fifty external tools in ten categories, practical research pathways and a query launchpad. Searches open the providers; no investigation results are retrieved by IIS.
External services · no results hosted here · queries sent only when you click a provider link.
Start with the question, then choose the tool
A register establishes a legal record, an archive preserves a page, and a map supports location checks. These resources answer different questions. Choose a pathway below, use its source log, then consult the provider directly.
Web archives and preservation

Image and video verification
Does this media match the claimed place, date and narrative ?
Maps, geolocation and satellites
Which clues can confirm a place and period ?
Companies and public registers
Which legal entity corresponds to the trading name ?
Public data and statistics
Can these figures be compared without changing their meaning ?
Public posts and accounts
How can a post be documented without premature author attribution ?
Domains and public infrastructure
Which public observations clarify a domain without contacting its target ?
Sanctions lists and namesakes
Does a name match actually refer to the same entity ?
Method, documentation and learning
How can a file be produced that another reader can verify ?
A useful research session in six steps
- Write the fact to establish and the decision it informs.
- Set the authorised scope and what must not be shared with third parties.
- Choose a primary source and an independent corroborating source.
- Record exact queries, identifiers, dates and the original documents.
- Test a competing explanation and resolve meaningful contradictions.
- Stop when the question is answered; state remaining uncertainty and the next action.

Questions about tools and external searches
Where are search results displayed?
On the selected provider’s website, in a new tab. IIS does not retrieve, host or display investigation results. Directory filters only filter the editorial catalogue.
Is the typed query stored?
The launchpad builds links inside your browser, without sending the query to IIS or storing it in browser storage. Clicking a prepared link sends the query to the named provider, under its own rules.
Are all tools free and available in every language?
No. Access may require an account, subscription, software or quota. The catalogue is available in French and English; providers set their interface languages, coverage and conditions.
Does no result prove that a fact is false?
No. Index coverage, spelling, language, access limits and capture dates can explain a missing result. Record what was searched and what remains unknown.
