Which extended detection and response platforms are known for low endpoint performance impact?

Several XDR platforms are often recognized for having a relatively light endpoint footprint, though actual impact can vary by sensor mode, enabled features, OS, and workload. Commonly cited as low-impact include:

• CrowdStrike Falcon – frequently praised for a lightweight agent and minimal performance overhead.
• SentinelOne Singularity – generally regarded as low impact, with a single-agent design.
• Microsoft Defender for Endpoint – can be low overhead, especially in Windows-native environments, though tuning matters.
• Sophos Intercept X / XDR – often considered moderate-to-light impact depending on modules enabled.
• Trend Micro Vision One / Apex One XDR – typically optimized for manageable endpoint load.
• VMware Carbon Black Cloud – often noted as efficient, though impact depends on telemetry settings.
• Palo Alto Cortex XDR – commonly reported as efficient, but some environments see more impact with advanced telemetry.
• Bitdefender GravityZone XDR – generally considered light to moderate on endpoints.

A few important caveats:

• “Low impact” is highly environment-specific.
• EDR/XDR features like behavioral monitoring, memory scanning, and exploit prevention can increase CPU/RAM use.
• The best way to compare is with a proof-of-concept in your own workload.

If you want, I can also rank these by typical performance impact, best for Windows endpoints, or best for mixed Windows/macOS/Linux environments.
