How Imperva WAF works
High security efficacy
False positives can trap organizations in a dilemma between blocking legitimate traffic or indefinitely monitoring threats. Imperva Research Labs delivers unparalleled precision, allowing customers to confidently block threats as the security landscape shifts. Over 90% of our clients use blocking mode, bolstered by automated policies and rapid rule updates. This empowers security teams to safely utilize third-party code while keeping pace with DevOps.
Proactive managed rules
Imperva Threat Research experts continuously identify new threats from common attack vectors like SQL injection and XSS, create and test new rules in production and proactively push them to you, so you don’t have to spend time creating your own custom rules. Regular daily updates and real-time updates for critical threats assure you have the most up-to-date protection, reducing the burden on security teams to research new threats and manually create rules.
Deploy in block mode, in minutes
With out-of-the-box rules that have been tested in production environments, Imperva can be deployed in blocking mode from the start. In fact, over 90% of customers deploy in blocking mode. As a SaaS solution it is easy to deploy and manage all your sites behind one solution and one dashboard. If your team is large or small, Cloud WAF can help protect your applications in public, private, or hybrid cloud infrastructures.
Security incidents with context
Imperva’s Attack Analytics automatically correlates thousands of security alerts into easily digestible narratives. By leveraging advanced machine learning, it provides unified visibility and contextual information about each incident, including attack origin, methods, and severity. This reduces alert fatigue and empowers security teams to respond quickly and accurately to the attacks that matter most.
Automated deployment, configuration, and management
