Our Mission:
Creating trusted open-source intelligence has always been our focus. Janes foundational defence intelligence, across military capabilities and order of battle, equipment, events, and defence industry, is verified and validated using our human-centric tradecraft to deliver the highest levels of assurance.
While open-source data is readily available to analysts and decision makers, it can be unmanageable in structure and volume, is not assured, and can be manipulated either intentionally or unintentionally. Janes open-source intelligence is verified and validated through our Tradecraft processes within our Single Intelligence Environment (SIE). Janes uses a multi-faceted approach to open-source intelligence, developed over 120 years, with all sources assessed for bias/objectivity, reliability, and level of certainty.
We excel at capturing and making sense of open-source information to regularly reveal new and timely insights. We provide clients with a definitive source of the ‘what’, the context to understand the ‘why’ and, particularly within our dedicated forecasting products, a prediction of what will happen in the future. Our news provides both a factual journal of record and commentary in order to add the necessary context behind the facts.
Our goal is to ensure our journalism and analysis is better, sharper, more relevant, more comprehensive, and more useful than other open-source providers. We achieve this through employing more than 250 analysts supported by many hundreds more freelance experts to source and verify information. Our experts are supported by technologies such as natural language processing, web scraping and monitoring, data visualization, and other analytical tool sets. A key value we provide is topic selection: deciphering what is salient, standing up the facts, and setting events into context .

To support our Tradecraft we need the best technology solutions and capabilities, particularly in an increasingly complex world with exponentially accelerating volume of relevant information accessible. To respond to this challenge Janes has invested heavily in Technology, both in terms of people and software development.
