View Imperva Web Application Firewall Review View Wallarm API Security Platform Review

Overview

Imperva and Wallarm both protect web applications and APIs, but Wallarm was built API-first while Imperva added API security to an established WAF. That architectural difference shows up in practice.

Wallarm automatically discovers your API endpoints, generates an OpenAPI schema from observed traffic, and applies security policies to each endpoint. It's designed for engineering teams shipping APIs at high velocity. Imperva offers broader WAF features (bot management, DDoS, data security) with API protection as an add-on module.

Choose Imperva for comprehensive web application security with enterprise support and compliance reporting. Choose Wallarm if API discovery and protection is your primary concern and you want a tool that integrates into CI/CD pipelines.
