Cloud-native prompt protection, now vendor-neutral and action-aware.
Prompt Shields detect prompt and document attacks inside Azure AI. VANGUARD governs agent actions across any cloud, model and tool.
Microsoft Prompt Shields and VANGUARD solve different layers.
Most AI security tools solve a different layer. VANGUARD focuses on runtime governance: what an AI system is allowed to do, in this context, for this tenant, with this tool, using this instruction.
Strongest fit: Azure AI prompt and document attack detection
Microsoft Prompt Shields provide cloud-native prompt and document attack detection inside Azure AI - tied to one cloud, focused on prompts.
Governed AI execution in production
VANGUARD controls trusted instructions, context access, tool execution, and audit evidence once AI systems start taking action - across agents, RAG pipelines, and MCP-enabled workflows.
VANGUARD vs Microsoft Prompt Shields, layer by layer.
Microsoft Prompt Shields is strong in its layer - VANGUARD governs the runtime above it. The two are complementary; teams often run both.
Govern actions, not just prompts.
Secure MCP & tool-calling
VANGUARD mediates API access, tool execution, retrieved context, and runtime workflow decisions with tenant-aware policies.
Control stateful AI risk
Agentic threats emerge across memory, retrieved content, tool output, and multi-step execution - not one turn at a time.
Produce governance evidence
Every runtime decision is recorded with ZKP evidence that supports audits, assurance reviews, and internal policy checks.
