Anthropic expands access to Claude Security plugin for beta testing

Anthropic has expanded access to its Claude Security plugin for Claude Code CLI, now available in beta. This new tool enables developers to scan their changes for vulnerabilities before committing, or to conduct a full codebase scan directly from their terminal. The release comes as part of a broader trend where AI coding assistants are integrating security plugins to streamline vulnerability detection within standard developer workflows, moving features that were once in limited previews into more widespread use.

Anthropic: Anthropic is an artificial intelligence company focused on developing advanced AI models, including the Claude family of assistants designed for safety, accuracy, and security. The company recently expanded access to its Claude Security plugin for Claude Code, making terminal-based vulnerability scanning available in beta to a broader set of users. This move builds on prior iterations of the tool to integrate security checks directly into developers’ existing Claude workflows.
Claude Code: Claude Code is Anthropic’s command-line interface and coding environment for interacting with Claude models to assist with software development tasks. The recent beta release of the associated security plugin integrates vulnerability scanning into this terminal-based workflow, allowing scans before commits or across entire projects. Updates in July 2026 have emphasized stability and plugin reliability for this tool.
Claude Security plugin: The Claude Security plugin is a beta feature for Claude Code that enables AI-driven scans of code changes or full codebases for vulnerabilities directly from the terminal. It leverages the user’s existing Claude inference to detect issues and support fixes without requiring separate security platforms. The plugin was made more accessible in this recent update, extending its availability beyond earlier limited previews.

Beta Accessibility: Features previously in limited research previews for Claude security tools have progressed to public beta releases for wider developer use.
Security Integration: AI coding assistants are incorporating specialized security plugins to enable vulnerability detection as part of routine developer terminal workflows.
