Application Security
Barracuda Application Protection
Web application and API protection combining WAF, DDoS mitigation, and ML-based bot defense.
Barracuda Application Protection Overview
What it does
Barracuda Application Protection is a Web Application and API Protection (WAAP) platform that combines a web application firewall, API security, bot defense, and distributed denial of service (DDoS) mitigation in a single offering. It shields web applications and APIs from the OWASP Top 10, zero-day exploits, data leakage, and application-layer denial of service attacks, and is delivered either as the Barracuda Web Application Firewall or as the cloud-hosted WAF-as-a-Service.
How it works
Traffic to protected applications flows through the WAF engine, which applies OWASP rule sets, rate limiting, brute force protection, and client IP reputation analysis. Barracuda Advanced Bot Protection applies machine learning, informed by the cloud-based Active Threat Intelligence service, to separate malicious and human-mimicking bots from legitimate traffic. Machine learning-backed discovery surfaces shadow and zombie APIs, and protection rule sets can be generated automatically from API definition files. The bundled Vulnerability Manager and Remediation Service finds application vulnerabilities and remediates them with a single click, and a REST API connects the platform to configuration management and SIEM tools.
Credentials and traction
WAF-as-a-Service is SOC 2 Type II certified, with the audit report available on request through the Barracuda Trust Center. Barracuda is listed as a Representative Vendor in the June 2026 Gartner Market Guide for Cloud Web Application and API Protection. The vendor serves more than 200,000 customers worldwide, and the platform targets small and midsized enterprises alongside managed service providers delivering it as a managed offering.
Key Capabilities
mapped to solution categoriesSignature- and rule-based detection and blocking of common web attacks such as those in the OWASP Top 10.
Detection and mitigation of volumetric and application-layer (L7) denial-of-service attacks.
Detection and mitigation of malicious automated traffic and advanced, evasive bots.
Machine learning and behavioral analysis to detect anomalous traffic and reduce false positives beyond static rules.
Rapid policy-based mitigation of newly disclosed application vulnerabilities without changing application code.
Controls request volume per user or client within defined time intervals.
Continuously discovers and inventories all APIs across the environment, including shadow and zombie APIs that are not tracked in the official catalog.
Detects and blocks malicious API behavior at runtime using anomaly and behavioral analysis trained on attack patterns.
Detects and rate-limits automated abuse, credential stuffing, scraping, and misuse of sensitive business flows.
Validates live API traffic against the documented OpenAPI or schema definition to catch undocumented endpoints, unexpected parameters, and drift.
Identifies APIs that transmit or return sensitive data such as personal information, credentials, or tokens, so exposure can be flagged and controlled.
