Purview, Sentinel, Entra Agent ID, and Microsoft Agent 365 cover data, identity, and connection. Elacity ECP is the control plane for what your Copilot Studio agents are told to do — prompt versioning, drift detection, and immutable instruction-level audit.
Between October 27–31, 2025, Microsoft retired GPT-4o as the default orchestration model in Copilot Studio and replaced it with GPT-4.1. Agents using generative orchestration were automatically migrated. There was no pull request. No change record in your ITSM system. No rollback gate. Every Copilot Studio agent running generative orchestration changed behavior in a four-day window. Purview logged the data access. Sentinel monitored the security signals. Entra tracked the identity. No Microsoft-native tool produced a governance record of the instruction baseline before and after the swap — or whether agent behavior drifted as a result.
Microsoft's compliance infrastructure is genuinely strong. Purview classifies data. Sentinel monitors security events. Entra Agent ID handles identity. Microsoft Agent 365 maintains the agent registry. Power Platform DLP enforces connector policies. ECP covers the layer between all of these — the instruction itself.
The Microsoft stack covers data, identity, and connectors. ECP covers the instruction.

Autonomous Actions Across M365
(Teams · Outlook · SharePoint · Dynamics · External APIs)Copilot Studio supports GPT-4.1, GPT-5, Claude Sonnet 4.5 and 4.6, Claude Opus 4.6, and bring-your-own-model via Microsoft Foundry. Microsoft's own 2026 guidance recommends using different models for different workloads. Different agents in your fleet run different models. A model update to one provider changes behavior for that subset only. The governance record for 'which model was active for which agent during which decision' lives nowhere in the Microsoft stack. ECP creates and maintains that record — unified, searchable, exportable.
Copilot Studio's 2026 strategy lowers the floor for agent creation so business users — not just developers — can build and deploy agents via Agent Builder and the M365 Copilot embedded experience. Right product direction. Also a governance surface that scales faster than IT can audit it. ECP extends instruction governance to maker-built agents, with appropriate tiering by risk level — same prompt registry, policy enforcement, and drift detection that IT-governed agents get.
Every topic instruction, generative orchestration prompt, system message, and action constraint — tracked, versioned, and diff'd. Centrally-governed agents and maker-built agents alike. Survives model retirements, prompt edits, and admin changes.
When Microsoft retires a model or you change the primary orchestration model, ECP runs a behavioral baseline comparison and flags affected agents for review before the change touches production traffic.
Copilot Studio agents schedule meetings, send emails, update CRM records, and trigger Power Automate flows autonomously. ECP adds a machine-speed policy check before high-stakes actions, with a complete log of the instruction state and policy decision that authorized it.
Running 50 Copilot Studio agents across Teams, SharePoint, and external channels? ECP monitors behavioral variance. When a customer-facing service agent starts exhibiting patterns outside its baseline, you know before your compliance team does.
ECP's instruction-level audit trail complements Purview's data audit logs — not replaces them. Together you get the complete record: what data was accessed (Purview) and what instruction drove the decision to access it (ECP).
Apply lighter-touch instruction governance to business-user-built agents and stricter policies to centrally-managed production specialists — without operating two separate registries.
Teams running Copilot Studio at scale who are being asked by legal or infosec to produce instruction-level audit records that Purview doesn't generate and Agent 365 doesn't store.
Owners of both centrally-governed production agents and maker-built agents from business users who need instruction governance that scales with agent proliferation, not just connector policy enforcement.
Security leaders with mature data and identity governance who recognize that the October 2025 model swap created a behavioral change across their agent fleet with no governance record attached.
Financial services, healthcare, government — where autonomous actions taken by Copilot Studio agents across Outlook, Teams, and Dynamics create compliance obligations that data-layer governance alone doesn't satisfy.
ECP doesn't replace Purview, Sentinel, Entra Agent ID, or Microsoft Agent 365. Every layer of the Microsoft compliance stack continues to do what it does — better than any alternative. ECP fills the instruction layer that wasn't part of the original design scope of those tools.
Connect ECP to your Copilot Studio tenant via Power Platform service principal.
Import current agent configurations, topic instructions, and generative orchestration prompts.
Define instruction baselines and policy ruleset per agent and risk tier.
Enable drift monitoring, model upgrade impact assessment, and autonomous action policy gates.
Estimated setup: 2–3 days for a standard Copilot Studio deployment
Ellavox AI runs Elacity ECP across ~1,000 active agents in production — voice, workflow, and enterprise integration use cases. The same control plane shipping to Copilot Studio enterprise customers now.
Flat governance capability pricing. Not per agent. Not per call. Not per token.
Scale your Copilot Studio deployment across as many agents, makers, and channels as Microsoft enables. ECP cost stays predictable.
Built for the governance layer that emerges when reasoning-based agents inherit a compliance infrastructure designed for deterministic systems.
