A web application firewall sits between your website and the internet, screening every request before it reaches your code.
How a WAF Works
Every visitor request — whether a normal page load or a malicious attempt — passes through the WAF first. It inspects the request against known attack patterns and either lets it through or blocks it, all before your website's actual code even runs.
Attacks a WAF Blocks
SQL injection attempts, cross-site scripting (XSS), malicious file upload attempts, and known bot attack patterns are all commonly caught and blocked at the WAF layer.
Why It's More Effective Than Fixing Code Alone
Even well-written applications can have unknown vulnerabilities. A WAF adds a protective layer that doesn't depend on every line of your code being perfect — it catches attack patterns regardless of which specific vulnerability they're targeting.
Real-Time Rule Updates
Good WAF services update their attack pattern rules continuously as new threats emerge, so your protection improves automatically without you having to patch anything yourself.
Included With CyberNet Hosting
CyberNet hosting plans include WAF protection through Imunify360 as standard, filtering malicious traffic before it reaches your site without any configuration required on your end.
