Show HN: Aegis.rs, the first open source Rust-based LLM security proxy (github.com)

Aegis.rs, a newly launched open-source proxy, is making waves in the AI/ML community as the first Rust-based security layer for large language models (LLMs). This innovative tool functions as a local reverse proxy that intercepts and analyzes every request sent to an LLM endpoint through a two-layer security pipeline, which can either block malicious inputs or forward clean requests. Remarkably, it requires no external runtime, operates without any code changes, and provides a transparent monitoring dashboard, boasting sub-millisecond latency. The significance of Aegis.rs lies in its unique deployment model compared to existing solutions like LLM Guard and Lakera Guard, which often necessitate invasive integrations or reliance on third-party services. Aegis.rs processes requests locally, ensuring that sensitive data never leaves the user's machine, while offering powerful features such as a heuristic engine and optional AI Judge for semantic analysis. With the ability to handle hundreds of requests per second on modest hardware and maintain a small memory footprint, Aegis.rs is poised to enhance the security and efficiency of utilizing LLMs, empowering developers with robust, customizable protection against various attack vectors.
