VPN service for mobile devices called WARP. A year later, beta support for macOS and Windows was released. As of 2020, Cloudflare was providing DNS services to over 100,000 customers. In April 2020, Cloudflare announced it was moving away from using reCAPTCHA in favor of hCaptcha. In November 2020, Cloudflare announced Cloudflare for Teams, consisting of a DNS resolver and web gateway called "Gateway," and a zero-trust authentication service called "Access." On May 11, 2022, Cloudflare announced its first SQL database, D1, which is built on SQLite. On September 26, 2022, Cloudflare announced Zero Trust SIM, an eSIM designed to secure mobile devices and prevent SIM-swapping attacks. The technology is based on the zero trust security model. According to Cloudflare, the secure eSIM can also be used as a second identification factor with 2FA verification protocols. The product will be first available in the United States, with a planned global rollout in the future. In September 2022, Cloudflare began to test Turnstile – an alternative to CAPTCHA. The product, instead of presenting a visual CAPTCHA for the user to solve, automatizes the verification process by conducting JavaScript-based checks inside the browser to determine whether the user is a real person or an automated entity. The algorithm reportedly uses machine learning to optimize the process. DDoS Mitigation Cloudflare received media attention in June 2011 for providing DDoS mitigation for the website of LulzSec, a black hat hacking group. In March 2013, The Spamhaus Project was targeted by a DDoS attack that Cloudflare reported exceeded 300gigabits per second (Gbit/s). Patrick Gilmore, of Akamai, stated that at the time it was "the largest publicly announced DDoS attack in the history of the Internet." While trying to defend Spamhaus against the DDoS attacks, Cloudflare ended up being attacked as well; Google and other companies eventually came to Spamhaus' defense and helped it to absorb the unprecedented amount of attack traffic. In February 2014, Cloudflare claimed to have mitigated an NTP reflection attack against an unnamed European customer, which they stated peaked at 400 Gbit/s. In November 2014, it reported a 500 Gbit/s DDoS attack in Hong Kong. In June 2020, it mitigated a DDoS attack that peaked at 250 Gbit/s. In July 2021 the company claimed to have absorbed a DDoS attack three times larger than any they'd previously recorded, which their corporate blog implied was over 1.2 Tbit/s in total. In February 2023,
