Speaker's Comment

"Attending this workshop will empower you to become an expert in Microsoft vulnerability responses! However, not all vulnerabilities marked as 'urgent' require emergency action. Using indicators like PoC availability and the CVSS vector values, we will explore how to evaluate which vulnerabilities your organization should address immediately."
