Shares of global cybersecurity and software companies plunged sharply on Friday after US-based AI firm Anthropic PBC unveiled a significant update to its flagship Claude artificial intelligence platform—Claude Code Security. The announcement reignited investor fears that advanced AI tools could disrupt traditional cybersecurity services and software markets, leading to a broad sell-off across tech stocks.
Claude Code Security is designed to autonomously scan software code for security vulnerabilities and suggest targeted patches, potentially reducing the need for conventional security tools and human-driven vulnerability assessments. In internal testing, Anthropic claims the tool has identified hundreds of previously undetected bugs, highlighting its potential to reshape how organisations approach code security.

Cybersecurity Sector Faces Downturn
The sell-off was led by major cybersecurity names, as shares fell in double-digit percentages based on market reactions:
- JFrog plunged as much as 24 %,
- Okta Inc slid over 9 %,
- Cloudflare Inc dropped around 7 – 8 %,
- Zscaler Inc and GitLab also recorded notable declines.
Funds tracking the sector were similarly hit, with key cybersecurity ETFs falling nearly 4 % or more, extending their year-to-date losses and marking one of the weakest periods for the industry in recent months. Investors are now weighing the possibility that AI-driven tools like Claude Code Security could materially weaken demand for traditional enterprise security suites and services.
Why Investors Are Nervous
Market participants say the latest update deepens concerns over AI’s disruptive impact. Claude’s ability to automate complex security processes that typically require specialised human expertise has led to renewed questioning of long-standing business models in the cybersecurity industry. Unlike legacy tools that flag vulnerabilities for manual review, Claude Code Security can suggest fixes in the same workflow—which some see as a potential competitive threat to established vendors.
The sell-off follows a recent broader slump in software-as-a-service (SaaS) and related tech stocks, a trend that analysts have dubbed the “SaaSpocalypse,” where fears around AI’s role in automating enterprise tasks have weighed on valuations across the board.
Longer-Term Outlook And Industry Response
Despite the near-term market volatility, some analysts argue that the sell-off may be overdone, emphasizing that traditional cybersecurity solutions—particularly those focused on layered defence, threat intelligence and human oversight—will remain essential even in an AI-augmented landscape. Others point out that AI tools can enhance rather than replace existing products, by assisting human teams in identifying and prioritising threats more effectively.
Industry observers also caution that the broader software sector has been under pressure recently, with AI-led innovation triggering a re-rating of tech valuations. While disruptive technologies can cause short-term pain for legacy players, they often create new markets and services over time.
For investors and cybersecurity professionals alike, the Anthropic update underscores a pivotal moment in the evolution of AI and cyber defence—one that could redefine competitive dynamics in the years ahead.
