Searchlight Cyber Launches The Practitioner’s Guide To The Dark Web

New book helps security professionals and law enforcement officers demystify and navigate the dark web


Searchlight Cyber, the dark web intelligence company, has published The Practitioner’s Guide To The Dark Web – a book designed to help security professionals and law enforcement investigators to navigate and demystify the dark web. Copies of the book are available from today at the Searchlight Cyber booth (#461) at RSA Conference in San Francisco and can be requested here. As well as the physical book, Searchlight Cyber is also launching The Dark Web Hub, where key information from the book will be updated as the dark web inevitably evolves.



The Practitioner’s Guide to the Dark Web provides readers with an overview of all of the major aspects of the dark web, to increase understanding of this often-misunderstood area of the internet and help investigators to understand where to begin in gathering dark web intelligence.

Its contents include:

  • An overview of what the dark web is – addressing misconceptions about the dark web and debunking common myths.
  • Detail on the most popular dark web networks – including The Onion Router (Tor), The Invisible Internet Project (I2P) and ZeroNet.
  • A deep dive into different “areas” of the dark web – including marketplaces, forums, and ransomware leak sites, with examples of the types of criminality that can be found on each.
  • A glossary of key dark web terms – and a visualisation of the “geography of the dark web”.
  • Top investigator tips – to help security and law enforcement professionals in their mission to combat dark web threats.

“Security professionals and investigators are increasingly required to understand the workings of the dark web in order to fulfil their roles. However, by definition, the dark web is difficult to search and navigate. Specialist software is needed to access it, dark web sites aren’t indexed on search engines, and when you do land on them, they are dangerous, hostile environments”, explained Dr. Gareth Owenson, CTO and Co-Founder of Searchlight Cyber commenting on the release of the guide. “Our objective with the Practitioner’s Guide To The Dark Web is to provide security teams and investigators with guidance on where they should be looking, what kind of activity they can expect to find, and critically, advice on how they can gather meaningful intelligence.”
