M365 permissions are just the starting point. When AI agents on Epic AI Platform connect to Xero, Salesforce, and HubSpot — running Microsoft Copilot, ChatGPT Enterprise, or Claude — you need a governance framework that follows them. With WA’s PRIS Act commencing 1 July 2026 and IPP 10 sitting directly on automated decision-making, this white paper shows you how.
Practical framework with tool-level implementation guidance
From the M365 ceiling to a 12-point governance checklist
Human-in-the-loop approval for high-risk AI agent actions

Every business deploying AI in 2026 is talking about Microsoft 365 permissions. SharePoint oversharing. Copilot governance. That conversation matters — but it is only half the story.
The real productivity gains from AI come from agents that work across your entire technology stack: pulling invoices from Xero, checking pipeline in Salesforce, updating projects in Monday.com, and sending follow-ups through Outlook — in a single workflow. The moment those agents leave the M365 boundary, your governance model does not follow.
This white paper explains the gap, the risks, and the framework we built to close it. It is written for business owners, IT leaders, and anyone responsible for how AI is governed in their organisation.
This white paper was published in April 2026. Three things have moved since then.
Epic AI Platform is now the branded layer. The “managed AI platform” referenced throughout the white paper is now Epic AI Platform, our Azure-hosted governance layer covering Microsoft Copilot, ChatGPT Enterprise, Anthropic’s Claude, and selected open source models on the roadmap. Same architecture, same five pillars — now with multi-model coverage under one governance framework.
WA’s PRIS Act commences 1 July 2026. IPP 10 imposes three obligations on automated decision-making that the standard AI architecture does not deliver on its own: notification, human intervention, and explainability. The white paper’s HITL framework and cross-platform audit trail directly address two of the three. Read our full PRIS Act analysis for the regulatory detail, including what is solved today and what is not.
AI Agent Development is now a service tier. The agents this white paper governs are now built through our AI Agent Development service — purpose-built autonomous agents with scoped permissions, deployment gates, and the governance framework described here wired in from day one.
14 pages of practical guidance — not theory, not vendor marketing. A governance framework you can implement.
Where Copilot governance stops and why most businesses are only governing half their AI exposure. Includes a breakdown of which business functions sit inside M365 and which do not.
Real scenarios showing AI agents working across Xero, Salesforce, SharePoint, and Outlook — and the governance challenges each one creates.
Overly broad API permissions, unmanaged agent identities, no unified audit trail, permission creep, no human review for high-risk actions, and unclear accountability.
Enforcement and access control, three-layer permission governance (platform, agent, task), automated tool risk classification, cross-platform audit and monitoring, and deployment gates.
How AI agents pause and request human approval before executing high-risk actions. The mechanism that makes cross-platform agents deployable in businesses that handle sensitive data.
How ThreatLocker, Defender for Cloud Apps, Purview, DefensX, and ISO 42001 map to the governance framework — including what each tool covers and where the gaps are.
An honest breakdown of which agent governance categories have credible commercial answers you can buy today (identity, policy enforcement, observability) and which are still open problems (reasoning chain reconstruction, cross-vendor identity federation, behavioural drift). Updated in our PRIS Act analysis.

This white paper describes the framework. We build it for our clients. If you are a Perth business ready to get AI governance in place — across Microsoft 365 and every other system your business relies on — we can help.
Every engagement starts with AI Governance as the foundation. From there, we build Managed AI workflows that connect your business systems, deploy purpose-built agents through AI Agent Development, or deliver Custom AI Development for bespoke solutions that go beyond the standard library.
Start with an AI Readiness Assessment to understand your current AI exposure, or read our blog post on why M365 governance alone is not enough for more context on the cross-platform challenge.

Business owners, IT leaders, CFOs, and anyone responsible for how AI is governed in their organisation. It is written in plain language for decision-makers, not engineers — though the tool-level implementation section has enough technical depth for IT teams to act on.
Yes — we ask for your name, email, and company so we can send you the PDF directly and keep you updated on AI governance developments that matter to your business. We do not spam, and you can unsubscribe at any time.
Cross-platform AI governance is the practice of managing how AI agents access, combine, and act on data across multiple business systems — not just Microsoft 365. It covers agent identity management, scoped permissions per system, unified audit trails, human-in-the-loop approval for high-risk actions, and deployment gates for any AI workflow that spans more than one platform.
The framework is applicable to any Australian business deploying AI agents across multiple platforms. The tool-level implementation section references the specific tools we use (ThreatLocker, Defender for Cloud Apps, Purview, DefensX, ISO 42001), but the governance principles apply regardless of which tools you deploy.
This white paper describes the governance framework that underpins all of our AI services. Every client engagement starts with AI Governance as the foundation, then builds toward Managed AI, AI Agent Development, or Custom AI Development depending on your needs. For businesses with WA Government exposure, our PRIS Act analysis maps the framework to IPP 10 obligations specifically.
