G8KEPR vs Gravitee
Gravitee is one of the most advanced traditional API gateways — with real AI gateway capabilities (v4.10/4.11), ML-based prompt injection detection across 8 models, protocol-native MCP proxy, A2A routing, and exceptional compliance credentials (ISO 27001, ISO 27701, SOC 2, HIPAA, PCI DSS). G8KEPR goes one architectural layer deeper: its Verification Engine validates what comes out — API responses, LLM outputs, and MCP tool results — before they reach the consumer or agent, a capability Gravitee's pillar dashboards don't yet close.

The Four Pillars
G8KEPR is a unified platform. Four capabilities working together that no single-purpose tool can match.
AI Gateway
Multi-LLM routing, automatic failover, cost tracking, prompt caching
MCP Security
Secure every AI agent tool call — registration, auditing, sandboxing
AI Threat Detection
Prompt injection, jailbreak attempts, PII leakage — 1,700+ ML patterns
Verification Engine
Structural, semantic, and constraint verification of every AI output
