Anthropic’s AI-Powered Vulnerability Scanner Sends Shockwaves Through Cybersecurity Industry

A new artificial intelligence-powered vulnerability scanner unveiled by Anthropic has sent shockwaves through the cybersecurity industry, causing shares of major cybersecurity companies to plummet.

Claude Code Security: A New Capability

Anthropic’s AI-powered coding assistant, Claude Code, has been enhanced with a new capability designed to scan code for vulnerabilities and suggest patches. The feature, dubbed Claude Code Security, is currently available in limited preview to enterprise and team customers.

Market Reaction

While the new capability is limited to identifying vulnerabilities in code, the market reaction has been significant, with shares of major cybersecurity companies such as CrowdStrike, Cloudflare, Okta, Zscaler, Tenable, Sailpoint, SentinelOne, Fortinet, JFrog, and Palo Alto Networks falling by as much as 10% in some cases. The decline has erased billions in market capitalization, with some companies experiencing partial recoveries and others remaining lower.

Industry Leaders Weigh In

Palo Alto Networks CEO Nikesh Arora recently stated that AI will not replace cybersecurity products anytime soon, citing confusion over why the market would treat AI as a threat to cybersecurity.

CrowdStrike CEO George Kurtz echoed this sentiment, highlighting that Anthropic’s AI itself acknowledges that the new security tool is not meant to replace CrowdStrike solutions.

Glenn Weinstein, CEO of software artifact management platform Cloudsmith, noted that the new Claude security tool is designed to complement existing security application testing tools, not replace them. He added that the vast majority of code running in production is typically sourced from third-party binaries, not code written in-house.

Guy Flechter, CEO and co-founder of Sola Security, commented that the market reaction to Anthropic’s announcement says more about the power of AI than the collapse of the security stack.

Flechter emphasized that Claude Code Security doesn’t replace endpoint, identity, or cloud platforms, but rather changes the mindset of how security can be done. He noted that AI is now strong enough to take on the burden of manual glue work between different security tools and platforms.

Joe Silva, CEO of vulnerability management firm Spektion, believes that this moment represents a fundamental shift in application security that goes beyond tooling and challenges the core assumptions of how defenders and attackers operate.

Silva highlighted that the new AI-powered vulnerability scanner is a powerful tool that can reason about code like a seasoned analyst, not just match patterns. However, he cautioned that this development should not be seen as a plateau, as attackers will inevitably weaponize AI skills to find unpredictable vectors and uncover dangers that static tools cannot detect.
