The client waits. The proxy answers fast.
Microsoft Presidio now supports Postgres Binary Protocol proxying, unlocking a direct path to scan, redact, and protect sensitive data without rewriting your application stack. This feature changes how teams integrate data security into high‑performance Postgres workflows. No slow parsing of text queries. No loss of protocol fidelity. Binary protocol proxying means your existing drivers keep running as‑is, while Presidio intercepts traffic at the wire level.
Postgres binary protocol is efficient. It handles prepared statements, parameterized queries, and data streaming at speed. By proxying it, Microsoft Presidio inserts itself between client and server. It reads each message, inspects fields for sensitive entities—PII, PHI, payment data—and applies redaction or masking rules before the data reaches the application or the database. This happens with minimal latency, preserving throughput under real load.
For engineers, the advantage is clear. Presidio’s proxy layer works with established Postgres drivers across languages. You keep transactions, batching, and type fidelity. Protocol messages are not downgraded to text, so numeric precision stays intact, binary blobs are untouched unless flagged, and array formats remain valid. It’s built to coexist with complex schemas and modern ORM implementations.
