Exposing the Invisible is Tactical Tech's 3-part series of short films examining some of the most inspiring and provocative investigative cases, those that go further than traditional journalistic investigations.

We spoke to hackers, activists and investigators from the UK, to Lebanon, Israel and Pakistan to find how they work with evidence, data and visualisation.

After watching each film, you can find out more about the tools and tactics used by the protagonists to expose the hidden layers behind problems in their societies. Each film comes with extensive interviews telling the story of each activist or investigator, divided into thematic chapters, as well as a bank of to help you follow in their footsteps.
