Business introduction

Do Something. Measure It

Enabling a Secure and Trustworthy Internet

The Global Cyber Alliance is a nonprofit organization dedicated to making the Internet a safer place by reducing cyber risk. We build programs, tools, and partnerships to sustain a trustworthy Internet to enable social and economic progress for all. GCA is a 501(c)(3) in the U.S. and a nonprofit in the U.K. and Belgium. Core Objectives: At GCA, we take on projects that are intended to make a global impact, that are scalable, and can measurably reduce cyber risk. 

We have determined specific goals that we strive toward and that shape our focus.

Our Vision: Our vision is a secure, trustworthy Internet that enables social and economic progress. 

Realizing this vision requires tackling a big problem: reducing cyber risk. We approach this challenge by building partnerships and creating a global community that stands stronger together. We tackle projects that will have a global impact, are scalable, measurable, and will reduce risk. To reduce the barrier to enable cybersecurity we make tools and resources freely available so that any organization or individual can take action right now.

Our Impact: We measure our work by the impact it makes. We tackle the biggest problems facing global communities. Our solutions are practical and freely available to individuals and organizations. We’re the Global Cyber Alliance, and we’re here to make a difference.
