Mitä Cloudflare tekee? Cloudflare Inc. is a San Francisco-based company founded in 2009 by Matthew Prince, Michelle Zatlyn, and Lee Holloway. The company's idea was to create a platform that protects websites from Distributed Denial of Service (DDoS) attacks by placing a protective barrier around the website's servers and filtering traffic. Cloudflare's business model focuses on cloud-based solutions for data centers, offering Content Delivery Network (CDN), Domain Name System (DNS), and DDoS security. However, in the early years, the company solely focused on DDoS defense. As the company grew, additional features were added to create a more comprehensive cloud management system. Cloudflare's services directly compete with other companies such as Akamai and Incapsula, which also offer web security and CDN solutions. However, what sets Cloudflare apart is the size and scalability of its network. The company relies on a network of data centers that allow it to filter all traffic-based attacks before they reach customers' servers. The company also has a strong presence in the open-source community. Cloudflare offers free open-source tools to help customers protect their websites and servers, as well as tools for speed optimization and performance improvement. Most of the tools Cloudflare offers are open-source tools released under the MIT license. Cloudflare offers a variety of products, including a Content Delivery Network (CDN), DDoS defense, Web Application Firewall (WAF), Domain Name System (DNS), SSL/TLS distribution, virtual private networks (VPN), and Load Balancing. Once the user adds their domain to Cloudflare, all traffic directed to the user's server is routed through Cloudflare's network. Cloudflare's CDN is used by customers to reduce webpage load times, particularly for pages with high traffic. This is achieved by storing content on various geographic locations, reducing latency and accelerating loading times. Cloudflare's DDoS defense provides users with protection against all types of DDoS attacks. Cloudflare monitors incoming network traffic and blocks malicious activities from botnets and other vulnerabilities. Cloudflare's WAF provides a layer of protection against HTML and HTTPS attacks on web applications. The WAF can protect users' applications in various ways, such as blocking XSS and SQL injection attacks, and also protects against other threats, such as the OWASP Top 10. Cloudflare's DNS system is a secure, fast, and easy-to-manage system that also offers protection against DDoS attacks. Cloudflare also provides SSL/TLS distribution, offering standard SSL/TLS distribution as well as the ability to customize the SSL/TLS distribution to meet specific customer requirements. Cloudflare's load balancing is another way to ensure that web traffic is evenly distributed. The load balancing options include built-in failover functionality to ensure traffic is redirected in the event of hardware failure. Cloudflare is utilized by some of the world's largest companies and websites, including the Mozilla project, the Massachusetts government, Red Hat, DigitalOcean, and NASDAQ OMX. Cloudflare is also known for its price transparency and its focus on data security and privacy. Cloudflare commits to its privacy policy, stating that user data will not be shared with third parties without informing and obtaining consent from the user. Overall, Cloudflare has developed many exciting technologies and services to protect its customers from security threats and improve the speed and performance of their web applications. The company remains focused on introducing new products and features to the market to provide customers with the best protection. Cloudflare on yksi Eurpooliin suosituimmista yhtiöistä.
