20 Free Tools for Cybersecurity Professionals

As a cybersecurity professional, staying ahead of the curve requires constant monitoring and analysis of open-source intelligence (OSINT). OSINT involves collecting and analyzing publicly available data from various sources to gather information about an individual, organization, or threat actor.

What is OSINT?

OSINT involves using publicly available data, such as social media posts, web pages, emails, and network traffic, to gather intelligence on a target. This can include information about an individual's online activities, organization details, IP addresses, domain names, and more.
