Extended detection and response (XDR) is a unified cybersecurity solution that collects and analyzes data from multiple sources to prevent, discover and respond to cyberattacks.
Benefits of Extended Detection and Response
According to Gartner, an XDR solution provides enterprise cybersecurity teams with:
- Improved protection, detection and response capabilities.
- Improved productivity of operational security staff.
- Lower total cost of ownership (TCO).
With a complete view of all potential network and endpoint vulnerabilities, enterprise security personnel can more effectively prevent cyberthreats. In the unlikely eventuality a cyberattack occurs, XDR enables faster discovery, response and remediation, freeing up valuable resources to focus on more impactful projects.
The primary value of an XDR solution is the simplicity of a combined, cohesive cybersecurity platform. XDR collects activity data across multiple security layers, including email, endpoint, server, cloud and network. Automated analysis of this data can detect threats as they happen, allowing security teams to investigate and act quickly.
Additional XDR benefits:
- Reduction in false positives and alert fatigue for cyberattacks.
- More accurate incident response.
- Comprehensive context for remediation and overall analytics.
- Streamlined operations and a smaller tech stack.
Extended Detection and Response Components
Extended Detection and Response Features
According to analytics firm Gartner, an XDR solution should include:
- Centralization of normalized data, primarily focusing on the XDR vendor’s ecosystem.
- Correlation of security data and alerts into incidents.
- A centralized incident response capability that can change the state of individual security products as part of incident response or security policy setting.
XDR solutions encompass EDR tools for attack prevention, endpoint monitoring, automated response action and threat hunting with dashboards and reports for visualizing data. XDR solutions unify visibility and management across endpoints, the enterprise network and cloud-based assets. An XDR solution should incorporate intelligence about cyberattacks from internal and external sources or advanced AI and machine learning capabilities to help identify current and evolving cyberthreats.
How Extended Detection and Response Works
XDR enhances an SOC's ability to deal with cyberattacks by:
- Detecting potential security incidents at endpoints and other vulnerable areas.
- Identifying actual cyberthreats versus non-incidents.
- Auto-responding to incidents by either containing or remediating based on custom rules.
XDR solutions can also improve protection capability by:
- Sharing threat intelligence with component security products to provide efﬁcient, unified blocking of threats.
- Aggregating weak signals from multiple components into stronger signals of a cyberthreat.
- Automatically correlating and conﬁrming alerts.
- Contextualizing relevant data for alert triage.
- Centralizing and prioritizing response and remediation steps.

What is XDR?
What is an XDR system?
An XDR system or solution encompasses tools for endpoint attack prevention, monitoring, automated response action and threat hunting with dashboards and reports. It also includes features for securing cloud storage, email and apps. XDR solutions unify visibility and management across endpoints, the enterprise network and cloud-based assets.
How does an XDR system work?
An XDR system secures enterprise networks by detecting potential security incidents at endpoints and other vulnerable areas, identifying actual cyberthreats versus non-incidents and auto-responding to incidents by containment or remediation based on custom rules.
Is XDR better than EDR?
Although endpoint detection and response (EDR) is an effective defense against cyberattacks, extended detection and response (XDR) expands on EDR with additional protections at the network, servers, cloud and application levels. Both EDR and XDR involve continuous monitoring, threat detection and automated response to cyberthreats, but EDR’s scope is limited to endpoints and XDR is more comprehensive.
BlackBerry for XDR
The global shift to remote work arrangements has increased cybersecurity risks beyond experts’ initial estimates. To address the growing number and severity of cyberthreats, CISOs and security analysts must look beyond traditional EDR solutions and start thinking in terms of XDR. Although securing endpoints is critical for protecting the environment, today's workplace demands holistic solutions that include network telemetry, behavioral analysis and continuous authentication.
