C-CIP is a human information sharing platform for information security professionals.

Open-source intelligence (OSINT) is intelligence collected from publicly available sources. In the intelligence community (IC), the term "open" refers to overt, publicly available sources (as opposed to covert or clandestine sources); it is not related to open-source software or public intelligence.

Activities:
• Gather cyber threat intelligence data from publicly available sources
• Discover tools and methods for analysis of threat intelligence data
• Research and report on newly discovered Common Vulnerabilities and Exposures (CVEs)
• Share newsworthy threat intelligence data and threat actor activity
