Cloudflare has announced a new feature in its Web Application Firewall (WAF) to help teams prevent data loss from external-facing applications. This feature scans and blocks responses that contain sensitive data, such as credit card numbers or social security numbers. The company also plans to add more patterns and the ability to search for specific data. Additionally, Cloudflare is working on a solution to scan all traffic leaving devices and locations for data loss without compromising performance. This feature will apply standard, consistent rules around what data can leave an organization regardless of how that traffic arrived in their network.
