Imperva Web Application Firewall

Imperva Cloud WAF is the web application firewall that lets more than 94% of its customers deploy in blocking mode from day one, which tells you everything you need to know about its false positive rate. The platform delivers real-time protection against all OWASP Top 10 threats by integrating WAF, bot protection, API security, and machine learning into a unified cloud-based service. Managed rules are written and tested by the Imperva Threat Research team before deployment, so your security posture improves continuously without requiring your team to tune rulesets like they're adjusting a vintage radio.

DDoS protection backs the WAF with 13 Tbps of global scrubbing capacity and fast time to mitigation, handling everything from Layer 3/4 volumetric floods (UDP, SYN, DNS amplification) to sophisticated Layer 7 application-layer attacks like HTTP request floods and SlowLoris. Advanced Bot Protection goes beyond basic rate limiting to prevent business logic attacks across websites, mobile apps, and APIs, stopping account takeover, credential stuffing, and competitive price scraping. API Security continuously discovers and classifies all APIs in your environment, including the undocumented shadow APIs that nobody remembers deploying but attackers always seem to find.

Imperva was named a Leader in the Forrester Wave for Web Application Firewalls, continuing a recognition streak that reflects years of consistent performance in independent evaluations. For organizations running web applications where downtime means lost revenue and a breach means lost trust, Imperva delivers the kind of always-on, low-maintenance protection that security teams actually deploy in production rather than leaving in monitoring mode indefinitely.
