XDR for Businesses

XDR (Extended Detection and Response) is a security platform that correlates threat data from multiple sources simultaneously: endpoints, network, cloud, email and identities. EDR (Endpoint Detection and Response) only protects individual devices. XDR extends this approach across the entire IT infrastructure and detects complex attacks spanning multiple areas. An attacker moving from a compromised laptop through the network to a cloud service is often missed by EDR, but identified and automatically stopped by XDR as a connected attack chain

SIEM (Security Information and Event Management) collects and stores log data from all IT systems for analysis and compliance, but requires significant manual effort to evaluate. A SOC (Security Operations Center) is the team that analyses SIEM data and responds to incidents. XDR is a platform that largely automates threat detection and incident response, reducing the workload for SOC teams. In modern architectures all three complement each other: XDR as the analysis and response engine, SIEM for compliance and long-term storage, SOC as the human oversight layer.

The leading XDR providers in 2025 are Microsoft Defender XDR (strong for M365-centric companies, already included in E3/E5 licences), CrowdStrike Falcon (market leader in the endpoint space with a broad XDR ecosystem), Palo Alto Networks Cortex XDR (comprehensive, enterprise-grade), SentinelOne Singularity (strong in automation and AI-based detection) and Trend Micro Vision One (strong for hybrid environments). The choice primarily depends on existing Microsoft, Cisco or security infrastructure. SAVECALL creates a vendor-neutral comparison matrix for your specific requirements.

XDR is worthwhile for businesses with more than 100 endpoints, hybrid cloud and on-premise infrastructure, compliance requirements under NIS2 or ISO 27001, no internal security team for manual analysis, and companies already using EDR that want more visibility across network and cloud. Endpoint Detection and Response is sufficient for small companies under 50 employees with a homogeneous endpoint landscape and low risk profile. SAVECALL honestly evaluates in the initial conversation whether XDR makes sense for your situation or whether EDR with a managed service delivers the same protection.

XDR licences typically cost between 8 and 25 euros per endpoint monthly, depending on provider and feature scope. Microsoft Defender XDR is already included for companies with M365 E5 licences. CrowdStrike Falcon ranges from 15 to 25 euros per endpoint. SentinelOne Singularity and Palo Alto Cortex XDR are similarly priced. Managed XDR as a service, where an external SOC monitors the platform and responds to incidents, costs 3,000 to 10,000 euros monthly for mid-sized companies. SAVECALL calculates total cost of ownership including implementation and ongoing operations.

Modern XDR platforms detect and correlate threats in real time with a mean time to detect (MTTD) of under 1 minute for known attack patterns. Automated response actions such as endpoint isolation, account lockout or network segmentation happen within seconds without manual intervention. Complex, unknown attacks (zero-day) are typically detected within minutes to hours through AI-based behavioural analysis. For comparison: without XDR, the average detection time is 207 days according to IBM X-Force. SAVECALL implements XDR including tuning of detection rules for your specific environment.
