OSINT TRAINING
Open Source Intelligence

Online open source research often yields disappointing results due to incorrect search behavior. However, applying the right research methods provides a wealth of valuable information. In collaboration with Reuser's Information Services, Triangular Group Academy now offers high-quality OSINT courses, taught and developed by Arno Reuser himself.

      Reuser's Information Services

During our OSINT course cyber-security, planning (so-called 'intell collection plans'), hands-on tools, the use of various search engines and operational tips & tricks are discussed on the basis of case histories. The students learn a methodical, effective and goal-oriented online research method. The training focuses on the OSINT research method developed by Arno Reuser, which focuses on planning, structure and systematics.

What is Open Source Intelligence (OSINT)

Nowadays, the issue when conducting research is not necessarily the shortage of valuable information, but rather the abundance of useless information. Accessible databases are so large that, with the incorrect search behaviour, it is a challenge to find the right piece of information. Open Source Intelligence (OSINT) was developed as a research methodology to make sense of the information jungle and produce a selection of information that is validated, reliable, timely, and accurate. With the help of OSINT research techniques and methods it is possible to turn millions of hits with a low relevance into a few hundred hits with high relevance. OSINT-skills are not only relevant for intelligence agencies, but also for employees at a public or private organisation that are occupied with conducting research on a daily basis or even for individuals.

About Arno Reuser

All OSINT-courses offered by Triangular Group Academy are designed and taught by Arno Reuser, owner and founder of Reuser’s Information Services (RIS). Arno Reuser is an authority in the field of Open Source Intelligence as he was responsible for setting up the OSINT-branch of the Dutch military intelligence agency (MIVD) in the 1990s from the ground up. At that time it was one of the very first OSINT-programmes in Europe. Since then, Arno has used his expertise in setting up his own company to meet the increasing worldwide demand for knowledge on Open Source Intelligence. Reuser’s Information Services has given OSINT lectures, workshops and training programmes to national and international governments, the private sector and academia. Currently, he is also an OSINT guest lecturer at Leiden University, and he has given multiple interviews and written academic articles.

Furthermore, he is a consultant on intelligence, security and Open Source Intelligence. In addition to his knowledge on OSINT, Arno is specialised in intelligence in general, cyber security, information warfare, and information security. Reuser's Information Services (RIS) was founded in 2008 by Arno Reuser and partnered with Triangular Group Academy in 2020.
