Comparison
ZNYX vs ZenGuard AI
Both detect prompt injection, jailbreaks, PII, and unsafe content, but they differ on deployment and openness. ZenGuard AI focuses on fast detectors delivered primarily as an API/SDK. ZNYX is an open-source runtime you self-host in your own boundary, with a deterministic-to-ML-to-LLM-judge escalation ladder and coverage across the OWASP LLM Top 10, agentic, and MCP surfaces.
What ZNYX is
ZNYX is an open-source detection runtime you deploy in your own perimeter and call from any language. It runs a fixed ordered detector pipeline and can escalate deterministic -> ML -> LLM-judge via an in-VPC inference sidecar, with a scorecard gate that keeps unproven model-backed enforcement advisory until benchmarked. Detection covers input/output plus retrieval, tool, agent-plan, agent-step, and memory-write stages and MCP.
What ZenGuard AI is
ZenGuard AI is an AI-guardrails offering centered on fast detectors - prompt injection, jailbreak, PII, allowed-topics, and toxicity - integrated via a Python SDK and delivered primarily as a low-latency API per its public materials. Its strength is quick integration and managed, low-latency detection without running detection infrastructure yourself.
ZNYX vs ZenGuard AI, side by side
The two take different architectural approaches. This table maps the dimensions that usually decide the choice.
| Dimension | ZNYX | ZenGuard AI |
|---|---|---|
| Deployment | Self-hosted in your boundary; data does not have to egress | Primarily a managed API/SDK service |
| Openness | Open-core: open-source runtime + inference sidecar | Proprietary service with an SDK client |
| Detection model | Deterministic -> ML -> LLM-judge ladder, worst-of aggregation | Fast individual detectors via API |
| Agentic & MCP coverage | Retrieval, tool, agent-plan, agent-step, memory-write stages + MCP | Core detectors (injection, jailbreak, PII, topics, toxicity) |
| Model-backed enforcement | Scorecard gate ties enforcement to measured accuracy | Managed model quality is the vendor’s responsibility |
| Data residency | Inspection stays in your environment (air-gappable) | Requests are sent to the managed service to be inspected |
When ZNYX is the better fit
- You need the data being inspected to stay inside your boundary (regulated, on-prem, or air-gapped).
- You want an open-source, inspectable engine rather than a black-box service.
- You want a graded ML/LLM-judge ladder with enforcement gated on measured accuracy.
- You are securing agents, RAG, tools, memory, or MCP - not only single-prompt detection.
When ZenGuard AI is the better fit
- You want the fastest possible integration and are comfortable calling a managed detection API.
- You do not want to run any detection infrastructure yourself.
- Your data-residency requirements allow inspected requests to leave your environment.
