OSINT, or open source intelligence, is a method of gathering information from publicly available sources to gain knowledge and insights. It involves collecting data from various places like online government records, social media profiles, news articles and online search engines, and piecing it all together to get a more comprehensive understanding of a person, group or topic.

What Is OSINT?

Open source intelligence (OSINT) refers to the practice of collecting information from publicly available and published sources, typically done by IT, cybersecurity or law enforcement professionals to understand trends, gather evidence and discover connections.

Because open source intelligence involves looking at information that is already available to the public, it does not require hacking or illegal activities. Rather, OSINT tools make it easier for users to wade through the countless data sources and documents that are out there in order to find the information they need and produce actionable insights. 


Why Is OSINT Important for Businesses?

OSINT has become essential for organizations across various industries to achieve success. Below are just a few ways businesses use OSINT to improve their everyday processes.

  • Threat Detection: Companies can discover when sensitive data is leaked online and detect other network vulnerabilities
  • Market Analysis: Businesses can collect info on competitors and consumer sentiment to determine whether to enter a new market or move forward with a product launch
  • Compliance: Organizations can stay on top of industry, local, national and international laws to make sure they meet compliance standards. 
  • Brand Image: Companies can scan social media platforms and other online sources to understand how consumers and customers perceive their brands
  • Operations: Businesses can track supply chain processes and respond quickly when disruptions occur. 

While plenty of information is ready for businesses to harness, it can be challenging to process these massive amounts of public data. That’s where OSINT tools come into play, allowing businesses to glean faster insights from open source data.
