Announcing Custom DLP profiles

What this post added

Introduced custom DLP profiles, enabling users to define their own detection patterns using regular expressions within Cloudflare Gateway. This extends DLP capabilities beyond predefined identifiers to detect unique sensitive data like intellectual property and trade secrets. The implementation leverages the Rust regex crate for pattern matching and integrates with HTTP policies for enforcement. The post also outlines the roadmap for future DLP enhancements, including data at rest scanning, minimum match counts, and OCR.
