What Is Managed Detection and Response?

Managed Detection and Response (MDR) denotes outsourced cybersecurity services designed to protect your data and assets even if a threat eludes common organizational security controls.

An MDR security platform is considered an advanced 24/7 security control that often includes a range of fundamental security activities including cloud-managed security for organizations that cannot maintain their own security operations center. MDR services combine advanced analytics, threat intelligence, and human expertise in incident investigation and response deployed at the host and network levels.

What challenges can Managed Detection and Response address?

As the volume, variety, and sophistication of cybersecurity threats increase exponentially, organizations struggle to maintain security operations centers staffed with highly skilled personnel and resources. As a result, Managed Detection and Response vendors provide a cost-effective menu of services designed to improve an enterprise’s cybersecurity defenses and minimize risk without an upfront cybersecurity investment.

MDR services provide higher skill-level analysts utilizing cutting-edge security tools and up-to-the-minute global databases beyond the reach and cost effectiveness of most enterprise budgets, skill levels, and resources. Thus, helping keep pace with continually evolving adversarial tactics and techniques.

MDR services provide an alternative to enterprises chasing the latest in advanced security products by integrating Endpoint Detection and Response (EDR) tools that become a challenge for security operations teams to learn and maintain. As a result, an enterprise’s level of threat monitoring, detection, and analysis are improved without the challenge and expense required to keep an internal security team fully staffed and up to date with the latest threat data.

MDR services are not limited to greater detection and response capabilities. They also provide proactive defense intelligence and insight of advanced threats to potentially overwhelmed security teams. Detection levels are improved while dwell time of breaches are reduced. Compliance challenges also can be met using MDR services providing full stakeholder reporting and log retention on a wide range of regulations and standards. 

Why choose MDR over MSSPs?

Managed Detection and Response services are often compared to Managed Security Services Provider (MSSP) services. While they share similarities, they also differ in technology, expertise, and relationship. MDR services are typically proactive and focus on threats. MSSPs are designed to be reactive and focus on vulnerabilities. Unlike MSSPs, MDR services focus on detection, response, and threat hunting rather than security alert monitoring. MSSPs manage firewalls, but do not necessarily provide the same level of threat research, analytics, and forensics as MDRs. MSSPs recognize security issues but are incapable of revealing details of the threat that MDR services provide. MSSPs use log management and monitoring, vulnerability scanning and often Security Incident and Event Management (SIEM) platforms to notify organizations of threats. Automated MDR analytics and responses to advanced threats, file-less malware, and breaches can augment MSSP services. MDR services rely on more-direct communications such as voice or emails to analysts, rather than portals. MSSP primary interfaces are portal and emails with secondary chat and phone access to analysts.

Here are typical MDR and MSSP service comparisons. Not all MDR providers include the same levels of capabilities and tools in the following services:ons.
