Atlassian CISO Adrian Ludwig has built a world-class product security team that focuses on issues directly related to customers, with a goal to improve the security posture of products and represent customer security expectations internally. The team is structured as a "Renaissance Team" with domain expertise spanning application security, cloud security, and incident response, and supports engineering by ensuring all products are secure by design. A diverse culture with a collaborative approach allows for constructive discussions and the ability to engage in different security backgrounds, while empowering engineers with ownership of security within their developed products. This helps motivate engineers to think of security as code and address risks quickly.
