Dec 8, 2021Matthew Prince, John Graham-Cumming

Summary
This post announces the acquisition of Zaraz by Cloudflare. Zaraz's technology provides a sandboxed environment for third-party scripts, allowing for strict control over their access and behavior. This mitigates security risks associated with compromised third-party scripts, preventing them from accessing sensitive data or causing performance issues. The acquisition aims to integrate Zaraz's capabilities into Cloudflare's platform to ensure all scripts running on customer sites meet modern security, reliability, and performance standards.
