Continue learning how to import and execute code from an object file. This time we will investigate ELF relocations.

Today, we’re announcing a new feature within the Teams Dash. We called it “Home”. We created Home with a simple goal in mind: design an adaptive and informative landing page where users can see a round-up of their environment.

As of today, Durable Objects beta access is available to anyone with a Cloudflare Workers® subscription.

The COVID-19 pandemic influenced which brands attackers exploited for phishing campaigns in 2021. For example, the World Health Organization and DocuSign made Area 1 Security’s 2021 March Hackness “Not-so-Sweet 16.”

Starting today, your team can use Cloudflare Access to build rules that only allow users to connect to applications from a device that your enterprise manages.

Throughout the day, Cloudflare has published blog posts on products created to secure our customers from credential stuffing bots, detect users with compromised credentials, and block users from proxy services. But what do we do inside Cloudflare to prevent account takeovers on our own applications?

Today we are announcing a new Cloudflare Web Application Firewall for all Cloudflare paid zone customers.

Private encryption keys stored in hardware security module offerings from all major cloud providers can now be used to secure HTTPS connections at Cloudflare’s global edge.

TLS key compromise is a risk for all web services. Taking lessons from Heartbleed, Cloudflare offers the latest features that make key compromise less of a risk.

Beginning immediately, any Cloudflare user with a Pro or Business site can take new action against bots. We’ve added advanced features in the dashboard and some exciting updates to analytics.

The word “bots” on the Internet is a fairly loaded one. My earliest ‘bot’ experience was on IRC, where bots were quite helpful in making sure your favorite channel didn’t get taken over by malicious users and allowed for fun games of trivia.

Today, we are announcing early access to API Abuse Detection. This technology will identify, secure, and protect API endpoints with unsupervised learning.

We're excited to introduce Page Shield, a client-side security product customers can use to detect attacks in end-user browsers.

Today, we're excited to announce Route Leak Detection, a new network alerting feature that tells customers when a prefix they own that is onboarded to Cloudflare is being leaked.

The increased use of cloud-based SaaS providers to store and access sensitive data introduces a swath of security risks as management of these resources can be unwieldy. The risk of data loss can be managed by using Cloudflare Access, API Shield, and Browser Isolation.

API Shield is growing with new functionalities: Schema Validation generally available, Managed IP List, more controls to manage certificates, and Data Loss Prevention.

Today, we’re excited to announce that your team can use Cloudflare’s network to build Zero Trust controls over the data in your enterprise - wherever it lives and however it moves.

Protecting endpoints from browser-born zero-day attacks and malware with remote browser isolation is now easy for teams of any size.

Cloudflare launches new integrations with CrowdStrike, SentinelOne, and VMware Carbon Black. Cloudflare for Teams customers can now restrict access to their applications based on security signals from their devices.

We’re announcing support for malware detection and prevention directly from the Cloudflare edge, giving Gateway users an additional line of defense against security threats.

Imagine your most critical systems suddenly stop operating. And then someone demands a ransom to get your systems working again. Or someone launches a DDoS against you and demands a ransom to make it stop. That’s the world of ransomware and ransom DDoS.

Magic WAN provides secure, performant connectivity and routing for your entire corporate network, reducing cost and operational complexity.

We know the promise of replacing MPLS links with a global, secure, performant and observable network is going to transform the corporate network and the industry itself.

We developed the Random Employee Chats application internally, with the goal of recreating the pre-pandemic informal interactions. Here's how we moved from a shared spreadsheet to Cloudflare Workers to automate the entire process.

Today we’re excited to announce a number of initiatives, starting with the integration of Cloudflare’s privacy-first web analytics into WordPress.com. This integration gives WordPress.com publishers choice in how they collect usage data and derive insights about their visitors.

Up until now, we wouldn’t cache requests with query strings until we saw them three times. We trace that behavior back to 2010, examine why we might have needed it, and show ourselves why we don’t need it anymore.

Introducing our autonomous DDoS (Distributed Denial of Service) protection system, globally deployed to all of Cloudflare’s 200+ data centers, and is actively protecting all our customers against DDoS attacks across layers 3 to 7 (in the OSI model) without requiring any human intervention.

A sophisticated Microsoft Office 365 credential harvesting campaign targets financial departments at companies across multiple industries, as well as newly-appointed CEOs and executive assistants.

Here is the story of how we took Cloudflare for Teams from initial concepts, to an MVP, to now a comprehensive security platform that secures networks, users, devices, and applications.

We explored almost 200 websites with the activated Automatic Platform Optimization feature in Chrome User Experience Report data. Automatic Platform Optimization consistently demonstrated better aggregate performance among sites we analyzed in TTFB, First Paint, FCP, and LCP metrics.

Today, we’re excited to announce the release of three of the most requested features: adding multiple websites to an account, supporting Single-page Applications (SPA) as well as showing Core Web Vitals in Web Analytics.

Anomaly Detection uses an algorithm called Histogram-Based Outlier Scoring (HBOS) to detect anomalous traffic in a scalable way. While HBOS is less precise than algorithms like kNN when it comes to local outliers, it is able to score global outliers quickly (in linear time).

A comparison between the Ampere Altra and the AWS Graviton2, the two ARM Neoverse N1-based processors.

Announcing Application policies in Cloudflare Gateway. With Gateway, users instead connect to one of Cloudflare’s data centers in 200 cities around the world where our network can apply consistent security policies for all of their Internet traffic.

Ever wondered if it is possible to execute an object file without linking? Or use any object file as a library? Follow along to learn how to decompose an object file and import code from it along the way.

When we launched Cloudflare for Teams almost ten years later, the vision was very much the same — build a secure and powerful Zero Trust solution that is ridiculously easy to use.

We've been experimenting with breaking up employees into random groups (of size 4) and setting up video hangouts between them. We're doing this to replace the serendipitous meetings that sometimes occur around coffee machines, in lunch lines or while waiting for the printer.
