Go-based Layer-4 proxy Aegis secures Postgres from AI agent SQL attacks

By PulseAugur Editorial · [1 sources] ·

A developer has created Aegis, an open-source Layer-4 proxy for PostgreSQL databases, written in Go. Aegis aims to prevent AI agents from executing destructive SQL commands by parsing queries using WebAssembly. It compiles PostgreSQL's C parser (libpg_query) into WebAssembly via wazero, enabling it to inspect the Abstract Syntax Tree (AST) of incoming queries. If a query is deemed unsafe, such as a DROP TABLE or an unconstrained DELETE, Aegis blocks it before it reaches the database, offering a deterministic and low-latency guardrail. AI

IMPACT Provides a deterministic, low-latency guardrail for AI agents interacting with databases, reducing risks of accidental data corruption or excessive compute usage.

    Compiling Postgres C-Parser to WebAssembly in Go: Building a Layer-4 Guardrail for AI Agents

    <p>If you've ever wired an LLM agent or a text-to-SQL script up to a Postgres database, you know the anxiety: one bad hallucination and the model runs a <code>DROP TABLE</code>, wipes rows with an unconstrained <code>DELETE</code>, or gets stuck in a loop that burns through your …
