Buying EDR

Buyer's guide.

Evaluation criteria

Detection content. Behavioural rules; ML detection; threat intelligence integration.

Endpoint coverage: macOS, Windows, Linux, mobile. Mismatches create gaps.

Performance impact: CPU and memory on endpoint. Excessive impact drives user resistance.

CrowdStrike Falcon: market leader; comprehensive; expensive.

SentinelOne: similar capabilities; competitive pricing.

Microsoft Defender for Endpoint: bundled with E5 licensing; tight Microsoft integration.

SIEM integration mandatory. EDR alerts feed correlation; standalone EDR misses context.

Identity provider integration. EDR detects; auto-disables compromised accounts.

Ticketing and SOAR integration. Automated triage and response.

Phased rollout: pilot, expanded pilot, production. Catches deployment issues before fleet-wide impact.

Per-region considerations: GDPR-compliant data handling for EU endpoints.

Quarterly tuning: false positives, missed cases, performance impact.
