Tools

The web browser is a powerful OSINT tool that provides access to numerous websites and both open source and proprietary software tools that are either purpose-built for open source information collection or which can be exploited for the purposes of either gathering of open source information or to facilitate analysis and validation to provide intelligence. A cottage industry of both for-profit and not-for-profit investigative and educational groups such as
Bellingcat, IntelTechniques, SANS and others offer indices, books, podcasts and video training materials on OSINT tools and techniques. Books such as Michael Bazzell's ''Open Source Intelligence Techniques'' serve as indices to resources across multiple domains but according the author, due to the rapidly changing information landscape, some tools and techniques change or become obsolete frequently, hence it is imperative for OSINT researchers to study, train and survey the landscape of source material regularly. A guide by Ryan Fedasiuk, an analyst at the

Risks for practitioners

Professional associations and certifications
The OSINT Foundation is a professional association for OSINT practitioners in the United States Intelligence Community. It is open to U.S. Citizens and seeks to raise the prominence of the open-source intelligence discipline.
OSMOSIS (an association for OSINT professionals) provides courses and conferences that lead to the designation of being Open-Source Certified (OSC). OSMOSIS is an offshoot of the Hetherington Group, a private investigation and corporate & market intelligence group. According to the OSC, its goal is to "help standardize our profession and demonstrate that our members are Legal, Ethical, and Competent practitioners of investigating and analyzing Publicly Available Information." Further they state that, "To obtain the OSC designation, practitioners must meet certain requirements to demonstrate dedication to their craft and pass a 100-question exam."
The company IntelTechniques offers online and live training that can lead to the Open Source Intelligence Professional Certification (OSIP) and/or help individual practitioners develop and formalize their skills, sans certification. Their certification program "provides participants with an opportunity to work through a real-world scenario and demonstrate that they can produce an intelligence product that meets a high professional standard."
In addition to their training program, IntelTechniques.com offers a community that serves supports those seeking the OSIP certificiation, but is also open to practitioners who enroll in the training program itself without the intention of seeking certificiation. This community facilitates an exchange of information about best practices, the training itself and tradecraft & methodology in a moderated environment.
Other organizations including Bellingcat, offer training as well other options for OSINT practitioners to associate and exchange information on OSINT best practices and issues.
