Barracuda Web Application Firewall

Barracuda Web Application Firewall (WAF) is a comprehensive web application and API protection platform engineered to safeguard critical web applications, APIs, and microservices against application-layer cyberattacks, OWASP Top 10 vulnerabilities, zero-day exploits, and DDoS attacks. Deployable as physical hardware appliances, virtual appliances, or public cloud instances across AWS, Azure, and Google Cloud, it delivers resilient application perimeter defense.

The WAF operates inline as a reverse proxy, inspecting all incoming HTTP/HTTPS traffic and API payloads in real time. Key platform features encompass automated mitigation of SQL injection, cross-site scripting (XSS), and CSRF attacks, advanced bot protection to prevent credential stuffing and web scraping, XML and JSON schema validation for REST APIs, Layer 7 DDoS mitigation, SSL/TLS hardware offloading, and automated security rule tuning. The platform continuously monitors application behavior and generates targeted security policies to protect emerging web services.

Enterprises in e-commerce, banking, and healthcare deploy Barracuda WAF to ensure high availability and prevent application compromise. The solution integrates with Barracuda Cloud Control, Terraform, and enterprise SIEM platforms like Splunk and IBM QRadar. Common operational use cases include shielding vulnerable legacy web applications with virtual patching, protecting modern RESTful API backends from automated bot abuse, terminating heavy cryptographic handshakes, and achieving strict compliance with PCI-DSS Section 6.6 requirements.
