Full OSINT Pathfinder online training programme in two different time zones, going through the entire OSINT Intelligence Cycle from requirement analysis to delivery of results
- October 2025
The price for the full course is €1.689,- including 21% VAT (btw).
The OSINT Pathfinder training programme redesigned for online training, called OSINT Explorer.
The OSINT Explorer is a classroom training online to accommodate customers who cannot travel.
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. How to search for 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. 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.
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 OSINT Explorer will be run entirely online to accommodate participants who are unable to travel to The Netherlands.
We shall use ZOOM as our hosting platform. The training documentation will be available prior to training start.
The Preparation Newsletters will explain in detail how to use ZOOM to get the most out of the programme.
The price for the full course is € 1.689,- including 21% VAT (btw).
This includes the full training programme, all sessions, documentation and all listed in What You Get.
IMPORTANT. Please make sure to pay a few weeks prior to training start to allow package and delivery of the documentation.
