EDR (endpoint detection and response) and XDR (extended detection and response) are technologies. MDR (managed detection and response) is the managed service that continuously operates them — the 24/7/365 SOC team that monitors, investigates and responds to threats on the client’s behalf, built on top of EDR, XDR, or another detection stack.

NGAV (next-generation antivirus), EDR (endpoint detection and response), XDR (extended detection and response), and MDR (managed detection and response) are not four separate products bought independently — they are overlapping capabilities and delivery models. NGAV is a prevention capability, normally built into an endpoint protection platform or an EDR solution, that uses AI and behavioral analysis to block known and unknown threats.

The cybersecurity industry’s evolution from perimeter protection to holistic visibility, detection, and response is perhaps best illustrated in the evolution from endpoint protection platforms (EPP) to comprehensive security solutions that provide holistic protection for an organization’s ever-expanding attack surface, including network, cloud, and identity. Extended detection and response (XDR) is one of those solutions.

With the rise of data breaches and hacking attempts, a strong cybersecurity posture is the most significant need today. Given the scale of cybercrime growth, you need to carefully consider several key factors that will ultimately impact the cybersecurity solution you pick. Businesses have realized the value of their data; now they must invest in tools to easily detect and respond to security issues.

Extended Detection and Response (XDR) is a comprehensive security solution that integrates various security products and data into a simplified, unified system. XDR security combines prevention, detection, investigation, and response to provide a holistic cloud-based security approach.

The extended detection and response (XDR) market has evolved rapidly in recent years. What once seemed like a race to add new features is now giving way to a different debate: how to effectively integrate the different security layers that make up modern infrastructure. With increasingly distributed IT environments, including endpoints, identities, networks, and cloud applications, the volume of security signals that need to be analyzed to detect threats has multiplied.

Antivirus just isn’t enough anymore — not even close. Ransomware attacks constantly grow more sophisticated, zero-day vulnerabilities appear frequently and attackers increasingly rely on legitimate tools already inside a network rather than just on traditional malware. Antivirus alone just can’t protect organizations from all of those threats.

From hunting threats to solving complex problems to coding on a couch, adventures in the Black Hat NOC (Network Operations Center) are always interesting. Over the last few months and several shows, I’ve had the privilege of working with one of the other NOC partners, Cisco, to design and test our first integration between Corelight Investigator and Cisco XDR.
