About the Open Source Security Summit

The free and virtual Open Source Security Summit is a forum to explore the intersection of open source and security. Building on the previous three Summits, this year’s event will continue the conversation with cross-industry experts and dive deeper into why open source solutions lead to better security outcomes, as well as how using open source tools can build trust with customers and consumers.

Subsequent events expanded to cover the topic in-depth, with attendees and business stakeholders discussing their open source strategies, challenges, and efforts to make open source security understandable to both software developers and users.
