A web application firewall (WAF) protects your website and web applications from cyber threats and harmful traffic, like cybercriminals and bad bots. A WAF is like having a force field around your site—it only lets good visitors in and keeps malicious ones out. Beyond protecting your website, your web application firewall comes with a content delivery network (CDN) proven to accelerate your website speed by as much as 50 percent. Websites are attacked approximately 50 times per day, per website.
