Features Comparison

open-appsec

  • ML-Based Detection

    Pre-trained machine learning engine detects threats based on context and intent, not signatures. No rule tuning required.

  • Automatic Learning

    Continuously learns application-specific traffic patterns in production, reducing false positives over time without manual intervention.

  • Native Proxy Integration

    Runs as a module inside NGINX, Kong, or Envoy rather than as a separate proxy, eliminating additional network hops and latency.

  • Kubernetes Ingress

    Functions as a Kubernetes Ingress Controller with built-in WAF, providing security at the ingress layer without sidecars or service mesh.

  • API Protection

    Protects REST APIs against OWASP API Top 10 threats using the same ML engine, with automatic API discovery and schema enforcement.

  • Anti-Bot

    Detects and mitigates automated attacks, credential stuffing, and web scraping using behavioral analysis.

Wallarm API Security Platform

  • API Discovery

    Automatically discover and inventory all APIs with visibility into sensitive data flows and business-critical endpoints.

  • API Abuse Prevention

    Patented AI/ML detection for sophisticated API abuse, credential stuffing, and account takeover attacks.

  • Cloud-Native WAAP

    Web application and API protection deployable across any environment with single-day implementation.

  • Security Testing

    Integrated DAST and automated fuzzing to proactively identify vulnerabilities in APIs and applications.

  • API Attack Surface Management

    Agentless discovery of external API hosts, missing WAF coverage, vulnerabilities, and API leaks.

  • Agentic AI Protection

    Specialized protection for AI-powered applications and agentic AI systems.
