PortEden vs Microsoft Purview
Microsoft Purview is your data archive, classification, and DLP layer across Microsoft 365. PortEden is your AI access plane — the thing that sits in the request path when Claude, ChatGPT, Gemini, or Copilot asks for data. They're complementary: Purview catalogs, classifies, and retains; PortEden decides what an AI client can ask for in real time.
- You need to control what AI clients (Claude, ChatGPT, Gemini, Copilot, custom agents) can see and do at request time.
- You want a redaction and policy layer that operates inline at the API boundary, not after the fact.
- Your AI use spans multiple vendors — Purview's AI controls are tied to Microsoft 365 Copilot.
- You need controls on Google Workspace data, not just Microsoft 365.
- Your data classification, retention, and after-the-fact DLP scanning are your primary needs.
- You're a Microsoft 365 shop using Microsoft 365 Copilot exclusively and the built-in Purview integration is sufficient.
- You need cross-tenant compliance reporting and litigation-hold capabilities — Purview's bread and butter.

How each handles real scenarios
Microsoft 365 Copilot is being rolled out and the security team needs per-team scoping
Purview's sensitivity labels gate what content Copilot can ingest. PortEden adds a second layer: for non-Copilot agents (Claude Desktop, ChatGPT custom GPTs, internal LangChain apps) that touch Outlook and SharePoint via Microsoft Graph, PortEden enforces per-agent allowlists, scope downgrades, and audit. Run both.
Purview alone covers Copilot ingestion if every AI workflow is M365 Copilot. The moment a user adds a non-Microsoft assistant to the mix, Purview's controls stop applying.
A user pastes a customer record into ChatGPT desktop while drafting an email
If the user is using PortEden's Outlook MCP server, PortEden filters the API response to ChatGPT and redacts the customer record's PII based on rule. Pure clipboard paste is out of scope for any tool — neither PortEden nor Purview can intercept it.
Purview's endpoint DLP can block the paste at the OS level if the file is classified and the policy is configured for ChatGPT.exe. This is a separate Purview SKU and requires endpoint agent deployment.
Compliance asks 'which AI tools accessed which files in the last quarter?'
Per-tool log: agent identity, file ID, rule fired, timestamp. Exportable to S3 / Sentinel / Splunk on Enterprise. Covers Gmail, Outlook, Drive, SharePoint, Jira, Notion.
Purview Activity Explorer captures the same for Microsoft 365 Copilot and any tool reporting via Microsoft Information Protection labels. Non-Microsoft AI clients are not in scope unless integrated via Graph API audit logs separately.
