Cybersecurity stocks rally $280B on AI earnings outlook; Palo Alto, CrowdStrike in focus

The cybersecurity sector has gained $280 billion in market value this year as investors price in AI-accelerated threat detection and incident response. Palo Alto Networks and CrowdStrike earnings reports this week will test whether the sector's valuation expansion is supported by real AI revenue growth or hype.

Enterprise SOC and MDR teams increasingly rely on foundation models to triage alerts and correlate signals—a workflow that commands premium pricing. If earnings reveal AI attach rates below 30–40% of new ARR, the rally may face profit-taking; if above, it validates the multi-year security-AI thesis.
