What is WAF – Web Application Firewall?

A Web Application Firewall (WAF) acts as a protective barrier between your web application and the internet. It filters HTTP/HTTPS requests and blocks malicious traffic to safeguard websites from common web attacks such as SQL Injection, Cross-site Scripting (XSS), Layer 7 DDoS, and other vulnerabilities.

How WAF Protects Business Systems

A WAF is a critical layer of defense that helps secure customer data, user accounts, and backend systems by:

• Analyzing Web Traffic: Unlike traditional firewalls that only inspect network traffic, WAF deeply inspects every request to detect unusual behaviors, malicious code, or unauthorized access attempts.

• Blocking Exploits in Real Time: Using rule-based filters and machine learning, WAF can detect and block threats like zero-day attacks and vulnerability exploits.

• Ensuring Compliance: Helps businesses meet compliance standards such as PCI-DSS and GDPR, reducing the risk of penalties and data breaches.

Which Business Sizes Benefit from WAF?

WAFs were once considered a solution only for large enterprises. However, with the rise of digital transformation, even small and medium-sized enterprises (SMEs) are vulnerable to attacks—often due to weaker cybersecurity postures.

Today’s modern WAF solutions offer flexible pricing, easy deployment, and minimal technical barriers, making them ideal for SMEs—especially those running eCommerce sites, payment gateways, or customer data platforms.
