What is a managed detection and response?

Managed detection and response services provide customers with modern remotely distributed security operations center (MSOC) functions. These functions allow organizations to detect, analyze, investigate and actively respond quickly by mitigating and containing threats. MDR services offer an alternative to companies looking for the latest in advanced security products by integrating endpoint detection and response (EDR) tools, which make it a challenge for security operations teams to learn and maintain. The objective of the MDR is to address this problem not only by detecting threats, but also by analyzing all the factors and indicators involved in an alert.

By using advanced security analysis on endpoints, user behavior, applications and the network, the MDR provides deeper detection compared to traditional MSSPs, which rely primarily on rules and signatures. Once a detected potential threat is correlated and prioritized, a team of qualified security operations center (SOC) personnel investigates the source and extent of the attack, after which a detailed analysis of the threat and its impact is determined. Traditionally, organizations have turned to Managed Security Service Providers (MSSPs) for their external security needs. Unlike MSSPs, MDR services focus on detecting, responding to, and searching for threats rather than monitoring security alerts.

No number of people can analyze all your security and IT data to detect modern threats and respond quickly to attacks. As a result, managed detection and response providers offer a cost-effective menu of services designed to improve a company's cybersecurity defenses and minimize risk without an initial investment in cybersecurity. XDR is an extended detection and response system that collects data from any source (endpoint, cloud, network, identity, etc.) to provide complete visibility and stop known and unknown threats in more than just the terminal. Managed Detection and Response (MDR) is an advanced managed security service from Atos that provides threat intelligence, threat search, security monitoring, incident analysis and incident response.

Haunted by next-generation attacks and threatened by politically motivated regional threats, a major global oil and gas conglomerate chose Atos' AI-powered Managed Detection and Response (MDR) service to protect its critical infrastructure. MSSPs manage firewalls, but they don't necessarily provide the same level of threat research, analysis and forensic analysis as MDRs. MSSPs use log management and monitoring, vulnerability scanning, and often security incident and event management (SIEM) platforms to notify organizations about threats. Managed detection and response services are often compared to managed security service provider (MSSP) services.

Managed detection and response (MDR) refers to outsourced cybersecurity services designed to protect your data and assets, even if a threat evades common organizational security controls. MSSPs have security professionals who perform log management, monitoring and analysis, but often not at a very deep level.
