Network security is an issue that cannot be neglected by both enterprises and individuals today. With the increasing frequency and severity of cyberattacks, protecting websites and applications from malicious intrusions and theft is a necessary step for every internet user. However, traditional firewalls and security software cannot effectively block the latest and most complex online threats, such as SQL injection, cross-site scripting (XSS), zero-day attacks, and more. These attacks result in severe damage to the functionality, performance, and reputation of websites and applications, even leading to the exposure of sensitive data and the consequent legal liabilities.

Cloudflare WAF services provide the solution to the above issues, offering protection and prevention needed to ensure the security and stability of your online assets.
