Naive byte-range caching can waste gigabytes of origin bandwidth on small requests. We rebuilt our cache architecture in Pingora to coordinate partial fetches automatically, cutting R2 p99 latency in half. https://t.co/o99PwoZOQa

Cloudflare's new post-quantum GeoKey Manager protects geographically fenced decryption keys from harvest now, decrypt later attacks. Learn how we redesigned our cryptography stack to support strict data sovereignty in a post-quantum world. https://t.co/FUIioE4Ono

Beware of Mecha Kitty, watch until the end. #CloudflareConnect

Three days in SF, one very full Moscone West, and more conversations than we could keep count of.
#CloudflareConnect 2026 is officially in the books, and our feet would like to file a formal complaint.
Thank you for showing up, sharing what you know, and making it so easy to love our jobs this week.

Cloudflare's web application firewall can now correlate an HTTP request with its response. Full transaction detection helps every customer find successful exploits, data exposure, and risky misconfigurations that request-only inspection can miss. https://t.co/j5C7a4GoLM

[Cloudflare @Cloudflare]

Cloudflare has deployed default web application firewall (WAF) protections for newly disclosed PHP vulnerabilities before public disclosure. The rules use request and response signals to stop exploit attempts and prevent exposed data from reaching attackers. https://t.co/OQG4x6x858

[Dane Knecht 🦭 @dok2001]

PHP sites behind Cloudflare already have an initial set of WAF rules deployed for the known exploit vectors in these vulnerabilities. The rules are available to all customers, including free.

We are seeing early attacks emerging and are updating mitigations as new vectors show up.

This is a STOPGAP only. Patch as soon as @ThePHPF releases the update at 14:00 UTC today.

Almost 100,000 Commerce[.]com domains now give AI agents real shopping tools through WebMCP on Cloudflare. Here's how we turned it on across every store at once, while keeping each merchant in control. https://t.co/h09fJxuwzO

[Cloudflare @Cloudflare]

That's a wrap on Day 2 of #CloudflareConnect.

Agents are already browsing, buying, and building for us, and they definitely aren’t filling out CAPTCHAs. Today put that new kind of Internet user front and center.

Thank you to everyone who joined us. See you tomorrow for Day 3!

introducing Trusted Agent Delegation (TAD)

@Cloudflare and @worldnetwork are collaborating on a new framework to enable secure agent delegation

the ultimate goal is for TAD to empower people to use their personal agents on any site across the internet, without sites getting crushed by fraud/abuse from bad bots or bad actors

today at Cloudflare Connect we presented our shared vision for an approach centered around restoring the relationship between sites and users when using hosted agents, which is currently obscured

it will also support next generation attestations and verifications, starting with World ID's Proof of Human

we will publish the white paper and establish a working group in the coming weeks to collaborate with the broader agent ecosystem

Following the discovery that eight eMudhra intermediate certificates use weak keys, Cloudflare is deploying mitigations and releasing client updates. We explain the impact, our response, and what customers and developers should do next. https://t.co/lYGxHb3PHS
