A web application firewall (WAF) is a security feature designed to protect websites from malicious online activity. It works by inspecting incoming and outgoing traffic for malicious content. If it identifies something suspicious, usually through its own set of rules, the WAF will block the request and alert the site administrator. This helps protect against a wide range of cyber threats such as SQL injection attacks, cross-site scripting (XSS), data breaches, and distributed denial of service (DDoS) attacks. WAFs are essential tools in defending against cyber threats and help ensure websites stay secure for users. With the ever-evolving landscape of cyber threats, investing in a WAF is an important step to ensuring your website’s safety and security.
