A Web Application Firewall protects your website from threats like SQL injection, XSS, and bots.

It filters traffic before it reaches your site, blocking malicious requests. Popular options include Cloudflare, Sucuri, and ModSecurity. Set up one via best web hosting.

WAFs are especially useful for WordPress and e-commerce sites with login or payment forms.

They also help maintain uptime during attacks and reduce server strain.

For any business site, a WAF is a must-have for long-term security.
