Okta and CrowdStrike posted strong beats and sharp rallies, while SentinelOne’s softer forward profitability outlook caused a decline. CrowdStrike’s record $333 million net new ARR, 26% revenue growth, raised FY27 ARR guidance, and AI-security adoption are offset by roughly 34x CY27 sales valuation and competitive risk; Rubrik’s muted reaction and Palo Alto Networks’ elevated expectations remain relevant.
