G8KEPR vs Helicone
Helicone is a well-built AI gateway and observability platform with native prompt injection detection (Meta Prompt Guard), semantic caching, LLM evaluations, and strong cost analytics — a solid choice for teams focused on LLM visibility and routing. Budget enforcement is alert-based rather than hard-limit enforced. G8KEPR extends beyond the LLM observability layer: it covers traditional API traffic, runs its own ML threat classifiers rather than depending on Meta's models, adds complete MCP agent security, and pairs a Verification Engine inline on every output — not as a post-hoc evaluation step.

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 — 1,500+ ML patterns
Verification Engine
Structural, semantic, and constraint verification of every AI output
