Technology expert Juan Guevara examines open-source intelligence, commonly known as OSINT, and how publicly available information can be collected, analyzed and combined to reveal patterns that may not be obvious when individual pieces of data are viewed separately.

OSINT is widely used by governments, intelligence agencies, law enforcement, journalists, investigators and businesses. The same principles can also apply to ordinary Internet users, whose social media activity, photographs, public records and other digital information contribute to an increasingly detailed online footprint.

Guevara also discusses digital privacy tools such as GrapheneOS and encrypted communications services, along with the broader challenge of maintaining privacy in a world where smartphones, online accounts and connected services constantly generate information.

The segment highlights an important reality of modern cybersecurity: protecting personal information is no longer only about preventing someone from hacking a device. It also requires understanding what information is already publicly available and what can potentially be learned when those individual data points are connected.
