Cloudflare is accelerating its post-quantum roadmap. We now target 2029 to be fully post-quantum (PQ) secure including, crucially, post-quantum authentication.

Cloudflare was designed to be simple to use for even the smallest customers, but it’s also critical that it scales to meet the needs of the largest enterprises. While smaller customers might work solo or in a small team, enterprises often have thousands of users making use of Cloudflare’s developer, security, and networking capabilities. This scale can add complexity, as these users represent multiple teams and job functions.

Exactly 8 years ago today, we launched the 1.1.1.1 public DNS resolver, with the intention to build the world’s fastest resolver — and the most private one. We knew that trust is everything for a service that handles the "phonebook of the Internet." That’s why, at launch, we made a unique commitment to publicly confirm that we are doing what we said we would do with personal data.

We're proud to introduce Programmable Flow Protection: a system designed to let Magic Transit customers implement their own custom DDoS mitigation logic and deploy it across Cloudflare’s global network. This enables precise, stateful mitigation for custom and proprietary protocols built on UDP. It is engineered to provide the highest possible level of customization and flexibility to mitigate DDoS attacks of any scale.

Client-side skimming attacks have a boring superpower: they can steal data without breaking anything. The page still loads. Checkout still completes. All it needs is just one malicious script tag. If that sounds abstract, here are two recent examples of such skimming attacks: To further our goal of building a better Internet, Cloudflare established a core tenet during our Birthday Week 2025: powerful security features should be accessible without requiring a sales engagement.
