Competitive Landscape

Who SentinelOne, Inc. competes with, and how they differ.

CrowdStrike8.3/10

CrowdStrike is the EDR/XDR revenue leader with the broadest Falcon platform (endpoint, identity, cloud, SIEM), giving it more platform breadth than SentinelOne's more recently assembled Singularity portfolio.

1 product reviewed on TopReviewed

Palo Alto Networks8.2/10

Palo Alto Networks sells XDR (Cortex) as one module inside a much larger network, cloud and SOC security portfolio pursuing platform consolidation, versus SentinelOne's narrower AI-native endpoint-to-cloud focus.

1 product reviewed on TopReviewed

Wiz8.3/10

Wiz is a cloud-native application protection platform (CNAPP) built agentless and cloud-first, overlapping SentinelOne's Singularity Cloud Security (acquired via PingSafe) but without SentinelOne's endpoint/EDR install base.

1 product reviewed on TopReviewed

Darktrace7.8/10

Darktrace's self-learning AI focuses on network and email anomaly detection rather than endpoint agents, competing more on autonomous-response positioning than on EDR/XDR core architecture.

1 product reviewed on TopReviewed

Vectra AI7.9/10

Vectra AI specializes in AI-driven network detection and response (NDR) and hybrid-cloud threat detection, a narrower scope than SentinelOne's full endpoint-to-cloud XDR platform.

1 product reviewed on TopReviewed

Splunk8.0/10

Splunk (now part of Cisco) competes as a SIEM/security-data platform, overlapping SentinelOne's AI-SIEM push built on the Scalyr/DataSet acquisition rather than at the endpoint-agent layer.
