Today we’re excited to announce Cloudflare’s partnership with Jamf to extend Cloudflare’s Zero Trust Solutions to Jamf customers. This unique offering will enable Jamf customers to easily implement network Data Loss Prevention (DLP), Remote Browser Isolation (RBI), and SaaS Tenancy Controls from Cloudflare to prevent sensitive data loss from their Apple devices.

Welcome to the second DDoS threat report of 2023. DDoS attacks, or distributed denial-of-service attacks, are a type of cyber attack that aims to disrupt websites (and other types of Internet properties) to make them unavailable for legitimate users by overwhelming them with more traffic than they can handle — similar to a driver stuck in a traffic jam on the way to the grocery store.

The most famous data breaches–the ones that keep security practitioners up at night–involved the leak of millions of user records. Companies have lost names, addresses, email addresses, Social Security numbers, passwords, and a wealth of other sensitive information. Protecting this data is the highest priority of most security teams, yet many teams still struggle to actually detect these leaks.

APIs account for more than half of the total traffic of the Internet. They are the building blocks of many modern web applications. As API usage grows, so does the number of API attacks. And so now, more than ever, it’s important to keep these API endpoints secure. Cloudflare’s API Shield solution offers a comprehensive suite of products to safeguard your API endpoints and now we’re excited to give our customers one more tool to keep their endpoints safe.

Acropalypse (CVE-2023-21036) is a vulnerability caused by image editing tools failing to truncate images when editing has made them smaller, most often seen when images are cropped. This leaves remnants of the cropped contents written in the file after the image has finished. The remnants (written in a ‘trailer’ after the end-of-image marker) are ignored by most software when reading the image, but can be used to partially reconstruct the original image by an attacker.

Cloudflare has done several deep dives into Zero Trust performance in 2023 alone: one in January, one in March, and one for Speed Week. In each of them, we outline a series of tests we perform and then show that we’re the fastest. While some may think that this is a marketing stunt, it’s not: the tests we devised aren’t necessarily built to make us look the best, our network makes us look the best when we run the tests.

In January and in March we posted blogs outlining how Cloudflare performed against others in Zero Trust. The conclusion in both cases was that Cloudflare was faster than Zscaler and Netskope in a variety of Zero Trust scenarios. For Speed Week, we’re bringing back these tests and upping the ante: we’re testing more providers against more public Internet endpoints in more regions than we have in the past.

Starting today, Cloudflare’s API Gateway can protect GraphQL APIs against malicious requests that may cause a denial of service to the origin. In particular, API Gateway will now protect against two of the most common GraphQL abuse vectors: deeply nested queries and queries that request more information than they should.
