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.
