eBook: XDR: Extended detection and response

Year after year, the challenge of securing critical data intensifies. Evolving technology trends, including the recent growth in cloud and IOT adoption, continue to expand the enterprise cyber attack surface and make companies’ sensitive data more vulnerable to sophisticated attackers. At the same time, adversaries use those exact tools to increase their own power and scale, allowing them to efficiently wage repeated attacks – and they only need to succeed once. Future technologies threaten to exacerbate both of these problems.

Security teams have deployed tools, processes, and staffing models to respond to new threat vectors as they have emerged, but they are outnumbered and outgunned. The consequence of continually bolting new capabilities onto existing systems over time is an eventual mess of poorly integrated tools that require a lot of time, energy and experience to utilise.

XDR is a category of threat detection, investigation and response solutions that work across all threat vectors in a company’s infrastructure, rather than just one piece thereof. By increasing integration, XDR tools also increase visibility and insight for both for the machine learning models powering them and the security analysts using themyear after year, the challenge of securing critical data intensifies. By the end of this guide, you will have a clear understanding of what XDR is and what it is not; the advantages it has over legacy detection and response tools; which capabilities to look for when evaluating XDR solutions; and how XDR can help to simplify and improve your security operations.
