AVLab.pl - EDR-XDR Visibility & Correlation Assessment 2026

[harlan4096]

Hello!

We have completed the 2026 round of testing EDR-XDR solutions as part of our evaluation of telemetry quality, attack context, and host-to-host correlation.

In this edition, we did not focus on the effectiveness of threat detection, but primarily on what happens after an alert is generated - the quality of telemetry, event correlation, attack chain reconstruction, and practical operational value for SOC and Incident Response teams.

As part of the tests, we conducted multi-stage attack scenarios covering phishing, PowerShell, LOLBins, persistence, lateral movement, remote code execution, and data exfiltration.

Our goal was to verify whether the solutions under review provide analysts with sufficient data to understand the course of an incident, identify the source of the threat, and quickly take corrective action.

In summary, I can say that the differences between products increasingly lie not in attack detection itself, but in the completeness of telemetry, the quality of correlation, and the depth of analytical context.

Tested solutions:

1. Bitdefender - Bitdefender GravityZone XDR
   
2. CrowdStrike - CrowdStrike Falcon Insight XDR
   
3. Elastic - Elastic Defend XDR
   
4. Metras - Metras XDR
   
5. ThreatDown - ThreatDown EDR
   
6. WithSecure - WithSecure Elements EPP + EDR
