Ten practical OSINT research pathways
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.
A method for each source family
Each pathway sets a question, gives four practical steps, lists the fields to preserve and explains what its sources cannot establish. Use the tool links after defining your question, rather than collecting unrelated results.
Web archives and preservation
What did a page show at a particular time ?
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 ?
Write the conclusion as three separate statements
Observed
State what the cited material actually shows, with its date and scope. A register entry, a screenshot and a technical observation are different kinds of material.
Inferred
Explain the reasoning and competing explanations. Do not turn an association, a similar name or a missing result into an established identity or event.
Still to verify
Name the unresolved question, the useful next source and the condition that would change the decision. This makes the limits actionable.

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.
