Extended Detection and Response (XDR) is a security solution that helps organisations detect, investigate, and respond to cyber threats across multiple areas of their network, such as endpoints, emails, and cloud services. It collects and analyses data from various security tools to provide a more comprehensive view of potential threats, making it easier to spot attacks and respond quickly. XDR aims to improve threat detection, reduce response times, and strengthen overall security by connecting different security systems into one unified platform.
