Web Application Firewalls (WAFs) play a critical role in defending modern web applications from sophisticated cyberattacks. As web applications grow more complex, leveraging multicloud environments, microservices, and third-party integrations, they become more vulnerable to an evolving threat landscape. WAFs act as a security barrier, protecting applications from malicious activity such as code injections, scans, bots, and sensitive data leaks.
A WAF shields your applications by inspecting incoming traffic, identifying, and blocking attacks, while also ensuring that outbound traffic does not expose sensitive data. It offers virtual patching, addressing vulnerabilities in your applications and APIs in real-time without requiring changes to your application code.
Key features of WAFs include:
- Virtual patching for code- and application-level vulnerabilities
- Blocking malicious bots, attacks, and scans
- Preventing data exposure in outgoing traffic
- Securing APIs and preventing unauthorized access
By implementing a WAF, organizations can maintain a strong security posture, ensuring their web applications stay protected against evolving threats.
