What Dev Machine Guard does
Developer machines are the new attack surface. They hold high-value assets — GitHub tokens, cloud credentials, SSH keys — and routinely execute untrusted code through dependencies and AI-powered tools. Recent supply chain attacks have shown that malicious VS Code extensions can steal credentials, rogue MCP servers can access your codebase, and compromised npm packages can exfiltrate secrets.
