Extended detection and response (XDR) is the process of automatically collecting and correlating data across multiple security layers.
XDR delivers detection and response across all data sources, including email, endpoint, server, cloud workload, and networks. This allows for faster detection of cyberattacks, unauthorized access, and misuse, and provides improved investigation and response times through security analysis.
Attackers target many layers of the IT environment, including the corporate network, email servers, and cloud systems. Security teams must build a security toolset that enables effective detection and response to security threats
Extended detection and response helps resolve both security and operational challenges. It is a security solution that:
Extended detection and response is designed to help security teams:
XDR is not an antivirus.
XDR is a centrally managed security solution that protects networks and all their endpoints from various threats. An antivirus is a standalone security solution that protects the individual system or device it is installed upon from various malware activities.
XDR, on the other hand, is a complete solution with multiple capabilities, including intrusion detection, data encryption, and firewalls, etc. An antivirus works like a subset of XDR that detects and removes malicious files.
Endpoint detection and response (EDR) products monitor events generated by endpoint agents to look for suspicious activity. These solutions also collect data on suspicious activity and improve it with other contextual information from correlated events. However, EDR solutions do not offer integrations with other tools and data sources for full visibility.
XDR provides a wider view, integrating data from endpoint, cloud, identity, and other solutions, allowing for full visibility into an organization’s network and IT environments.
Security information and event management (SIEM) is a key element of the modern security operations center (SOC). SIEM pulls log data from dozens or hundreds of security tools to generate meaningful alerts and provides one interface for security analysis.
This is similar to XDR. However, SIEM only provides a summarized view of security data. This results in a very low level of detail.
SIEM cannot access or process additional information from other security tools to further investigate a specific incident.
In addition, SIEMs don’t have built-in response capabilities. SIEM is a detection tool that can identify security incidents but cannot stop or eradicate threats.
XDR has the following features that SIEM lacks:
Managed detection and response (MDR) is an outsourced service that offers dedicated personnel and technology to help companies improve the efficiency of security operations, threat identification, threat investigation, and threat response.
Endpoint detection and response (EDR) refers to a group of tools used to find and investigate threats to endpoint devices. EDR tools typically provide detection, analysis, investigation, and response capabilities.
Managed detection and response (MDR) solves challenges faced by security teams by strengthening a company's internal security team with external resources and personnel. An MDR service provider will offer an external Security operations center (SOC) that carries out the necessary actions to monitor and protect an organization’s IT assets. An MDR provider will likely use XDR solutions, but they will be controlled by external SOC analysts rather than an in-house team.
XDR solves security challenges by simplifying them and enabling in-house security teams to efficiently do their jobs. XDR unifies visibility across an organization’s security architecture and automates recurring and time-consuming tasks.
Endpoint detection and response tools integrate network, endpoint, cloud, and third-party data to prevent security attacks. XDR tools unify threat prevention, detection, investigation, and response all in one platform. XDR tools detect threats using behavioral analytics to help reveal the root cause of the threats.
Some of the benefits of using XDR tools include:
When choosing an XDR tool, here are some features to look out for:
Extended Detection and Response (XDR) software is a comprehensive cybersecurity solution that combines multiple security tools and technologies to provide enhanced threat detection, response, and remediation capabilities. XDR solutions go beyond traditional endpoint detection and response (EDR) systems by integrating data from various sources across the network, including endpoints, servers, cloud environments, and network devices.
This holistic approach enables organizations to gain better visibility into their entire IT infrastructure and respond to threats more effectively. There are several types of XDR software available in the market, each offering unique features and capabilities.
