Agata Proxima Offers a PostgreSQL Security Layer to Verify Access Controls

The piece argues that a working database connection or authentication system does not confirm that tenant isolation or authorized data access is actually happening. It introduces Agata Proxima, a PostgreSQL security platform aimed at helping developers enforce tenant-aware policies, verify access controls, and monitor database activity. The platform is described as adding protection without replacing PostgreSQL and is built on an open-source Rust proxy that developers can inspect. The article closes by asking backend engineers and security architects what evidence they would present to prove one tenant cannot access another's data.
