Trend Micro XDR Remediation

Enterprise Endpoint Detection & Response Tuning

Redesigned endpoint security posture for a major energy services provider — detection tuning, policy redesign, and remediation strategy materially reducing exposure across the fleet.

## Problem

An aging XDR deployment with noisy default policies was burning analyst hours on benign alerts while real lateral movement signals went uninvestigated.

## Approach

Audited every detection group against the environment's actual workload mix. Rebuilt exclusion logic, tightened response actions, and aligned policy bindings to a clean asset taxonomy.

## Fleet triage tooling

Console exports were processed programmatically rather than reviewed by hand — extracting the cloud instance ID embedded in each host name, discarding agents that were healthy or on stopped instances, and ranking what remained by failure mode so that unreachable and erroring agents surfaced ahead of merely absent ones. 353 instances carried agent-health issues at the start of the exercise. Splitting the same output by operating system turned one undifferentiated list into per-platform work packages.

## Outcome

A repeatable triage pipeline replacing manual console review, and a proxy migration executed across 12 operating-system platform groups spanning Windows Server 2008 through 2019 and five Linux distributions.
