Timely and ongoing communications with our customers is a key component in our efforts to best protect and secure their organization. There are instances where confidential advance customer communications can include early warning on Advisories to enable customers to further strengthen their security posture, prior to the Advisory being publicly released to a broader audience. This process follows best practices for responsible disclosure to ensure our customers have the timely information they need to help them make informed risk-based decisions.
