Microsoft Prompt Shields helps Azure AI users detect and block prompt and document attacks. RAGuard provides vendor-neutral runtime governance for agents, MCP tools, RAG systems, and autonomous workflows across enterprise environments.
Surfaces prompt and document attack signals inside the Microsoft security and AI ecosystem.
Applies consistent policy across providers, tools, MCP servers, and internal agents without locking governance to one stack.
Azure-native protection, enterprise procurement trust, Defender integration, and prompt and document attack detection for Microsoft-centric environments.
Vendor-neutral runtime governance across providers, cross-tool policy portability, MCP mediation, tenant-aware controls, and instruction provenance.

Microsoft provides valuable native controls for teams building on Azure AI. Prompt Shields can help detect user prompt attacks and document attacks, while Defender integrations surface relevant security signals in the Microsoft ecosystem.
RAGuard is designed for environments that extend beyond one provider. When enterprises combine Azure OpenAI, open-source models, internal RAG systems, MCP tools, SaaS integrations, and custom agents, governance has to travel with the workflow rather than stay locked inside one cloud.
Your AI estate is mostly Azure, you already centralise security operations in Microsoft Defender, and you need built-in prompt and document attack protection.
Your environment spans multiple models, providers, tools, or tenants and you need portable runtime controls plus policy and evidence that remain consistent across them.
