In a world drowning in data, finding reliable intelligence can feel like searching for a needle in a digital haystack. The sheer volume of information across countless channels and sources makes it incredibly challenging to pinpoint what you need.
That’s where the OSINT Pathfinder training programme comes in. Designed to transform you into an open-source intelligence master, this programme equips you with the innovative technologies and groundbreaking procedures to unearth the best possible information and get the answers you need.
Forget “Google Guessing”! Our programme centres around Arno’s OSINT Methodology, a proven, structured, systematic, and planned approach to finding reliable, validated, and authoritative open-source information. This in-depth system is absolutely essential for discovering those crucial “pearls” in the ever-expanding ocean of publicly available data.
This programme is comprehensive and will require dedication, but you’ll be fully supported every step of the way with extensive and detailed documentation.
We know the real work begins after the training. That’s why our expert instructors will be available for an entire year after the programme ends to answer your questions, resolve any issues, and help you find solutions.
The programme is packed with practical information that will help you change the way you do OSINT research.

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.
