Global Cyber Alliance

Global Cyber Alliance (GCA) is an international nonprofit organization that works to make the Internet more secure, trustworthy, and resilient. It brings together businesses, governments, civil society groups, technology providers, and other partners to turn separate cybersecurity efforts into coordinated global action. Its work focuses on improving the integrity of Internet infrastructure and helping people and organizations reduce cyber risk.

GCA offers practical, accessible tools and resources for individuals, small businesses, nonprofits, and other organizations. Its initiatives include cybersecurity toolkits, CyberFlex, DMARC resources, the Internet Pollution Index, the MANRS Observatory, and Quad9. The organization also supports projects addressing domain abuse, online scams, cyber resilience, and protection for mission-based organizations. Through GCA Learning, it provides guides and training, while its articles, reports, events, and public awareness campaigns share advice and research on current threats. GCA invites individuals and organizations to engage, collaborate, sponsor initiatives, or support its work through donations. Its overall mission is to strengthen the Internet and deliver practical protections that help its users participate more safely in an increasingly connected world.
