How Imperva WAF works

WAF efficiency

    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.

    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.

    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.

      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.

      Imperva’s Terraform provider automates Cloud WAF deployments. Through a modular design, Imperva’s Terraform module simplifies complex configurations, enabling teams to manage resources across various environments with greater efficiency. This approach enhances security operations and accelerates deployment times by leveraging modern Infrastructure as Code (IaC) practices​.

      Full management of SSL connections provides business continuity, security governance, automated certificate renewal and domain validation, and centralized observability. With Imperva enterprise SSL management, you can easily scale your certificates, avoid outages, and enhance security while reducing total cost of ownership.

      We don’t have to turn around and say, you know what? We need to change WAFs because they didn’t save the day. We say we need to keep this WAF because Imperva saved the day."
