Microsoft Purview VS Prompt Shields
Real-time prompt-level control and AI-specific governance across all LLM platforms. Zero-trust enforcement with privacy-first redaction that complements your existing Microsoft security investments.
Prompt-Level Control Before Data Leaves the Device
Microsoft Purview
Applied at file/email/document level with optional browser extension protection. Focuses on detecting sensitive content after transmission.
Prompt Shields
Inspects every AI interaction in real-time at the prompt layer. Prevents sensitive data from ever leaving the user's device, even before transmission to ChatGPT, Claude, or Gemini.
Private Redaction Without Cloud Dependencies
Microsoft's Approach
Relies on Microsoft's cloud analytics and policy engine, requiring data processing in Microsoft's environment.
Our Advantage
Uses on-device or private-hosted Small Language Models to detect and redact PII, business-sensitive terms, and hallucinated completions.
Why It Matters
Ideal for organisations requiring independence from hyperscaler AI for privacy-critical use cases.
AI-Specific Usage Governance
