Cloudflare WAF protects WordPress applications from two high-severity vulnerabilities
Cloudflare has deployed two WAF rules in response to high-severity vulnerabilities disclosed to us by the WordPress security team. The new rules protect all Cloudflare customers using affected WordPress versions, but customers should still update immediately to a patched release
A broken DNSSEC rollover took down .al. Now 1.1.1.1 tells you when validation is bypassed
When a failed DNSSEC key rollover took down the .al TLD, we deployed a Negative Trust Anchor to restore resolution. This time, though, clients didn't have to take our word for it: 1.1.1.1 returned EDE 33, a new DNS error code that signals directly in the response that DNSSEC validation was bypassed.
Introducing Precursor: detecting agentic behavior with continuous client-side signals
Precursor, our new continuous behavioral validation engine for bot management, offers visibility into how humans and bots actually interact across the full user journey. By turning session-level behavior into bot detection signals, it identifies advanced automation with higher precision — while reducing friction for legitimate users.
Improving Smart Tiered Cache for Public Cloud Regions
Smart Tiered Cache allows for precise upper tier selection for origins hosted on AWS, GCP, Azure, and Oracle Cloud with customer-provided cloud region hints.
Why we cannot wait for better post-quantum signature algorithms
NIST is advancing nine new post-quantum signature algorithms as potential candidates for future standardization. We take a closer look at all of them, and argue that while they are in the works and show great potential, we should use ML-DSA for now — the best one currently available.
Introducing Meerkat: an experiment in global consensus
Cloudflare Research is building a global consensus service called Meerkat that uses a new consensus algorithm called QuePaxa. We plan to use Meerkat to build a strongly consistent, fault-tolerant key-value store, and other applications.
Cloudflare proudly joins the UK government's Cyber Resilience Pledge
The pledge is a voluntary framework inviting organizations to commit to foundational cyber security governance, board-level accountability, and supply chain rigor. For over a decade, Cloudflare has pioneered the core pillars of this framework: democratizing security, leadership accountability, and radical transparency.

Unmasking the crawls with Attribution Business Insights
Cloudflare’s new Attribution Business Insights dashboard helps website owners understand crawler behavior, appetite, and potential value, fueling business-level conversations around crawl compensation.
Making AI search smarter
Search is how we find nearly everything on the web — creators, merchants, answers. AI is rewriting the rules, leaving creators caught between staying discoverable in an agentic era and getting paid for their work. Today we're launching two initiatives to help.
Your site, your rules: new AI traffic options for all customers
For our second Content Independence Day, we’re giving website owners finer options to manage AI traffic. Instead of a one-size-fits-all block, all customers can now easily distinguish and manage Search, Agent, and Training bots, alongside the new ability to protect ad-monetized pages.
Announcing the Monetization Gateway: charge for any resource behind Cloudflare via x402
We're opening the waitlist for our Monetization Gateway, which will allow you to charge for any web page, dataset, API, or MCP tool behind Cloudflare. The charges will settle in stablecoins over the x402 open protocol, with no payments stack of your own to build.
Content Independence Day, one year on: building the business model for the agentic Internet
One year after declaring Content Independence Day, a dynamic market for monetized content has officially emerged. In this report, we examine how the rise of autonomous AI agents is upending traditional search referrals and detail the new infrastructure required to support a sustainable web economy.
How we built saga rollbacks for Cloudflare Workflows
Cloudflare Workflows, our durable execution engine for multi-step applications, now supports saga-style rollbacks, allowing developers to specify a compensating action for each step.do().
Unlocking the Cloudflare app ecosystem with OAuth for all
Self-Managed OAuth is now available to all developers on Cloudflare. Here's how we executed a zero-downtime migration of our core OAuth engine to make it happen.
The White House's post-quantum executive order is an important milestone. It’s time to get to work
The new executive order sets a 2030 migration deadline and establishes a powerful foundation for post-quantum resilience. We look at what it gets right, where it can go further, and our migration playbook for government and industry.
How we found a bug in the hyper HTTP library
By rearchitecting the Images binding, we accidentally uncovered a bug that existed in the open-source hyper library across multiple major versions.
Temporary Cloudflare Accounts for AI agents
The moment an agent needs to deploy something, it slams face-first into a wall built for humans. Today we're rolling out Temporary Accounts on Cloudflare Workers. Any agent can now run wrangler deploy — temporary and get a live Worker in seconds.
