Is Claude Going to Kill Cloudflare Stock?

Cloud-native security stocks rarely trade in isolation, and the events of Friday, Feb. 20, proved that point with force. When Anthropic PBC introduced a research preview of Claude Code Security, a tool built to autonomously identify and patch software vulnerabilities, shares across the space retreated as participants weighed whether proactive, automated remediation could compress the long-term value of established enterprise security suites.

Cloudflare (NET) felt that pressure directly. The stock fell 8.1% on Feb. 20 as concerns spread that artificial intelligence (AI)-native systems may pull security further upstream, away from reactive monitoring and toward autonomous repair. Yet markets often overreact to the first headline.
