What Each Platform Does
LangProtect and NeMo Guardrails overlap in runtime protection and configurable AI guardrails, but differ in enterprise coverage, customization workflows, and security management.
| Capability | LangProtect | NVIDIA NeMo Guardrails | Advantage |
|---|---|---|---|
| Runtime AI Security | Dedicated AI Firewall for real-time inspection and enforcement | Configurable rails for inspecting and controlling AI interactions | Different approaches |
| AI Guardrails | 30+ scanners, policy controls, and customizable enforcement | Input, retrieval, dialog, execution, and output rails | Different approaches |
| Sensitive Data Protection | PII, PHI, secrets, and sensitive-data detection | PII detection and masking through configurable rails and integrations | LangProtect |
| Custom Security Scanners | 30+ scanners plus Custom Scanner Builder | Custom Python actions, Colang flows, and third-party integrations | LangProtect |
| Workforce AI Security | Employee AI governance, usage controls, and Shadow AI detection | Requires additional tools or implementation for workforce-wide coverage | LangProtect |
| AI Asset Discovery | Visibility across AI tools, applications, and workforce usage | No built-in enterprise-wide AI asset discovery in the open-source library | LangProtect |
| Centralized Enterprise Governance | Centralized policies, visibility, and security controls | Enterprise-wide administration requires additional implementation | LangProtect |
| Developer Customization | Configurable scanners and security policies | Open-source framework with Colang, Python actions, and extensible integrations | NeMo Guardrails |
