It\u2019s available as a limited research preview in the Enterprise and Teams editions of Anthropic\u2019s Claude artificial intelligence service. Additionally, the company plans to provide \u201cexpedited access\u201d for open-source project maintainers.<\/p>\n<p>Software teams scan their code for vulnerabilities using so-called static analysis tools. Such programs are usually built around a database of rules, or definitions of common cybersecurity vulnerabilities. A static analysis tool works by checking each single snippet of code in an application against its rules.<\/p>\n<p>Static vulnerability definitions can\u2019t cover every single variation of every single exploit. For example, one of a static analysis tool\u2019s rules might not support a niche programming language that a developer used to implement an interface module. As a result, rule-based static analysis tools often miss certain cybersecurity issues.\u00a0<\/p>\n<p>Anthropic positions Claude Code Security as a more effective alternative. According to the company, the tool doesn\u2019t use static rules but instead \u201creasons about your code the way a human security researcher would.\u201d It maps out how an application\u2019s components interact with one another and the way data moves through them to find potential weak points.<\/p>\n<p>Developers can activate Claude Code Security by connecting it to a GitHub repository and asking it to scan the code inside. According to Anthropic, the tool can uncover a wide range of vulnerabilities.<\/p>\n<p>Applications include filters that block malicious user input such as unauthorized SQL commands. Claude Code Security can find code snippets that lack an effective input filter. It also spots more sophisticated issues, such as vulnerabilities that make it possible to bypass an application\u2019s authentication mechanism.<\/p>\n<p>Claude Code Security ranks the security flaws that it finds based on severity. Additionally, it generates a natural language explanation of each one to expedite analysis. A \u201csuggest fix\u201d button below the explainer enables cybersecurity professionals to have Claude generate a patch.\u00a0<\/p>\n<p>CrowdStrike Holdings Inc. closed the trading session down almost 8%, while Cloudflare Inc. declined a little over 8%. Several other cybersecurity companies also logged share price declines. The selloff is the second that Anthropic has set off in the enterprise software ecosystem since the start of the month. The previous one was sparked by the company\u2019s launch of <a href=\"https:\/\/siliconangle.com\/2026\/01\/30\/anthropic-debuts-claude-cowork-plugins-help-users-automate-tasks\/\" rel=\"nofollow noopener\" target=\"_blank\">Claude Cowork plugins<\/a>.<\/p>\n<p>Claude Code Security is rolling out about four months after OpenAI Group PBC introduced a cybersecurity automation tool of its own. <a href=\"https:\/\/siliconangle.com\/2025\/10\/30\/openai-unveils-aardvark-autonomous-gpt-5-agent-built-hunt-software-vulnerabilities\/\" rel=\"nofollow noopener\" target=\"_blank\">Aardvark<\/a> offers many of the same capabilities as Anthropic\u2019s new tool. According to OpenAI, it tests vulnerabilities in an isolated sandbox to estimate how difficult it would be for hackers to exploit them.<\/p>\n<p>There are several ways OpenAI and Anthropic could expand their cybersecurity services over time.<\/p>\n<p>Enterprise software teams use systems called CI\/CD, or continuous integration and continuous delivery, pipelines to roll out software updates. The two AI providers could integrate their cybersecurity tools with popular CI\/CD products to automatically block updates that contain vulnerable code. Many established cybersecurity companies already offer such a capability.<\/p>\n<p>Image: Anthropic<\/p>\n<p>Support our mission to keep content open and free by engaging with theCUBE community. <strong>Join theCUBE\u2019s Alumni Trust Network<\/strong>, where technology leaders connect, share intelligence and create opportunities.<\/p>\n<ul>\n<li class=\"text-xl md:text-2xl text-gray-300 mb-8 max-w-4xl mx-auto\" data-replit-metadata=\"client\/src\/pages\/Home.tsx:123:12\" data-component-name=\"p\"><strong>15M+ viewers of theCUBE videos<\/strong>, powering conversations across AI, cloud, cybersecurity and more<\/li>\n<li data-replit-metadata=\"client\/src\/pages\/Home.tsx:123:12\" data-component-name=\"p\"><strong>11.4k+ theCUBE alumni<\/strong> \u2014 Connect with more than 11,400 tech and business leaders shaping the future through a unique trusted-based network.<\/li>\n<\/ul>\n<p><strong>About SiliconANGLE Media<\/strong><\/p>\n<p>SiliconANGLE Media is a recognized leader in digital media innovation, uniting breakthrough technology, strategic insights and real-time audience engagement.
