XDR

Extended Detection and Response: unified visibility across endpoints, network, email, and cloud to detect and respond to advanced threats faster.

What this service is (and isn’t)

What it is: XDR correlates signals across email, endpoint, identity, and cloud for faster detection and coordinated response.
Who it’s for: Teams outgrowing siloed EDR or AV who need analyst-friendly timelines.
What it’s not: Not a replacement for policy, identity, or backups—it extends detection depth.

From problem to outcome

Siloed tools miss lateral movement.

30-day: integrated views; 90-day: tuned detections and fewer false positives.

How it works

AssessData source inventory and integration gaps.
DesignUse-case library and severity mapping.
DeployConnectors, parsers, playbooks.
ReviewWeekly tuning; monthly leadership metrics.
