ShellWard is a powerful AI security middleware designed to safeguard AI agents from various threats, including prompt injection and data exfiltration. It operates as a standalone SDK or an OpenClaw plugin, providing an 8-layer defense mechanism that ensures robust protection against unauthorized access and command execution. The middleware employs a data loss prevention (DLP) model that allows data to be processed internally while blocking any sensitive information from being sent externally.

Key features include PII detection for sensitive information such as Social Security Numbers and credit card details, as well as a range of injection rules tailored for both English and Chinese languages. ShellWard boasts zero dependencies, making it easy to integrate with existing systems. With its high throughput for command checks and injection detection, it is ideal for developers and teams looking to enhance the security of AI-driven applications.
