AI Security Tool Sparks Major Stock Drop for Cybersecurity Companies

Monday, February 23, 2026 at 8:00 PM

Major cybersecurity companies saw significant stock declines Monday following the launch of Anthropic's new AI-powered security tool. CrowdStrike, Datadog and other firms dropped as much as 11% as investors worried about AI's impact on the cybersecurity industry.

Major cybersecurity firms experienced steep stock losses Monday as Wall Street reacted to the debut of a new artificial intelligence security product from startup Anthropic.

The AI company unveiled Claude Code Security, a feature that identifies serious security flaws in open-source software libraries and provides fixes for discovered problems.

Market reaction was swift and severe. CrowdStrike, Datadog and Zscaler each saw their stock prices tumble approximately 11%, while Fortinet and Okta declined about 6%. Palo Alto Networks dropped 3% and SentinelOne fell 5%.

The technology sector has faced mounting pressure in recent months as investors grow concerned about AI’s expanding abilities, especially after Anthropic introduced new plugins for its Claude language model in what appears to be an effort to expand into applications.

Shrenik Kothari, a security and infrastructure analyst at Robert W. Baird, characterized Monday’s market movement as ongoing investor anxiety. “What you’re seeing today is really the continuation of a panic-driven, narrative-led selloff,” Kothari stated.

However, Kothari noted important limitations in Anthropic’s new tool. Claude Code Security doesn’t perform immediate security functions like identifying active breaches, halting ongoing cyber attacks, or overseeing compiled software in live environments – capabilities that established security companies provide.

Market observers suggest the sell-off may be excessive, driven by oversimplified assumptions that artificial intelligence will eliminate the need for current cybersecurity products.

In related news, graphics chip giant Nvidia announced Monday it has partnered with Akamai, Forescout, Palo Alto Networks, Xage Security and Siemens to enhance immediate cybersecurity protection for industrial control systems.
