Cybersecurity Stocks Decline Amid AI Security Feature Announcement

On February 21, 2026, shares of several cybersecurity companies, including CrowdStrike Holdings, Okta, and Cloudflare, fell sharply following the announcement by Anthropic of a new security feature in its Claude AI. This feature, named Claude Code Security, is designed to scan code for vulnerabilities and suggest fixes, contributing to fears of reduced demand for traditional cybersecurity solutions. By February 23, 2026, stocks such as Palo Alto Networks and Zscaler had also dropped significantly, with declines exceeding 10%.
