Anthropic's AI Crushes Cybersecurity Stocks

The market tremor was triggered by the February 20th launch of Anthropic's "Claude Code Security." Unlike traditional static analysis tools that match code against known vulnerability patterns, this AI reasons about a codebase contextually, tracing data flows to find complex flaws that often evade human researchers. Anthropic's own model has already been used to find over 500 previously unknown vulnerabilities in open-source projects. The reaction was immediate and severe, erasing billions in market value from cybersecurity leaders. CrowdStrike's shares plunged by as much as 18% in the days following the announcement, while companies like Cloudflare, Okta, and Zscaler saw drops ranging from 5% to over 9%. This pushed the Global X Cybersecurity ETF to its lowest level since November 2023, reflecting broad investor concern about disruption. Incumbent CEOs quickly pushed back against what they termed a market overreaction. CrowdStrike's George Kurtz distinguished between Anthropic's tool, which he described as "proactive, development-stage security," and his own platform's "reactive, operational security" that detects threats at runtime. Kurtz even posted a screenshot of Claude itself stating it could not replicate CrowdStrike's complex, decade-plus engineering effort with a simple script. This event crystallizes a major narrative shift for VCs, where the focus has pivoted from incumbents with distribution advantages to AI-native startups. The core investment thesis is that AI-natives, built on clean-slate architectures without the burden of legacy tech debt, can iterate faster and challenge established SaaS models on both cost and capability. This trend is accelerating investor rotation out of traditional seat-based software stocks. In Turkey, the startup ecosystem is already shifting towards enterprise software
