Overview
Wallarm is an API security platform that has evolved beyond traditional WAF to address the unique challenges of protecting modern API-driven applications. The platform combines cloud-native WAAP (Web Application and API Protection), automated security testing, and API attack surface management in a unified solution.
Unlike traditional WAFs focused on web traffic, Wallarm was built API-first. The platform automatically discovers APIs, tracks sensitive data flows, and applies protection tailored to API-specific threats like those in the OWASP API Top 10. Machine learning powers both API discovery and threat detection.
A key differentiator is Wallarm's integrated security testing. The platform includes DAST (Dynamic Application Security Testing) and automated fuzzing capabilities, allowing teams to find vulnerabilities proactively rather than just blocking attacks reactively.
Ratings Breakdown

Frequently Asked Questions
How is Wallarm different from traditional WAFs?
Traditional WAFs were designed for web traffic—HTML pages, forms, and cookies. Wallarm was built API-first, understanding JSON, GraphQL, gRPC, and other API protocols natively. It also integrates security testing (DAST) that traditional WAFs don't offer, enabling proactive vulnerability discovery alongside runtime protection.
What does the free tier include?
Wallarm's free tier includes 500,000 monthly requests, API discovery, basic WAF protection, and community support. It's suitable for smaller projects, testing, or organizations wanting to evaluate the platform before committing to paid plans. No credit card required to start.
Can Wallarm protect non-API applications?
Yes, Wallarm includes full WAAP (Web Application and API Protection) capabilities that protect traditional web applications as well as APIs. However, organizations with primarily traditional web applications might find the API-specific features less relevant and could consider more traditional WAF options.
