In today’s world, massive amounts of ever-increasing freely available information in hundreds of channels and thousands of sources
make it very difficult to find exactly what you are looking for.
The OSINT Pathfinder training programme was designed to share precisely that. Innovative technologies and ground breaking procedures to find the best possible information from open sources to produce answers.
Arno’s OSINT Methodology is the heart of the programme.




Mastering ground breaking innovative techniques to find reliable, validated and authoritative open source information in a structured, systematic and planned way. A thorough, in-depth system is essential to find the pearls in the ever increasing ocean of publicly available information. No more Google Guessing (see the post about this phenomenon), but structure.
The programme will show that OSINT is much more than just randomly entering terms in an internet search engine or AI assistent. Search engines only cover a fraction of the open source information that is out there and AI bots are not reliable enough.
In addition, research in open sources should be safe, that is, protecting the identity of the researcher and safeguarding his/hers information profile and information position by applying important security measures.
The training will be a lot of work, but all is fully supported by extensive and detailed documentation to go on your own. But rest assured, since the real work for you starts after the training has ended, the teachers will be available for a year after the training for questions, issues and solutions.
Ground breaking, innovative skills and techniques to find the best information out there in support of decision making.
The programme is packed with practical information that will help you change the way you do OSINT research.
The Pathfinder aims to share Arno’s OSINT Methodology to
In addition: requirement analysis ; constructing an open source research plan, dark web research, the global information landscape, how to find out about…; news sources, country information sources, expert Boolean, best search strategies, and much more.
The programme is particularly suited for:
There is some technical stuff included, but extensive technical knowledge is not required to do the programme.
The training is not a Tool Tricks Training type of course. It is more about the WHY and HOW, the details are covered in the OSINT Training Manual and in the quick reference sheets.
It is about Arno’s OSINT Methodology to cover the OSINT Intelligence Cycle and the global open source information landscape, not limited to the world wide web.
The programme will be performed LIVE, with REAL TIME exercises so participants can see for themselves that Arno’s OSINT Methodology actually does work.
The programme runs for four full days, 32 hours in total.
The training aims to be practical and applicable. The goal is to have participants return to their office with a set of new capabilities and skills that can be applied immediately.
Prior to the training programme, we publish several Preparation Letters for participants with important information on how to best prepare for the training. Technical information and travel information is included.
The venue for the OSINT Pathfinder training programme will be the beautiful Fletcher Welness hotel in Leiden, The Netherlands.
The venue is very close to the historical city center with bars, cafes, restaurants, shopping and within easy reach of public transport.
