Device and endpoint governance
Useful for
Introduction
Identity is the root control plane, but the machines people use to access code, Microsoft 365, Azure and customer data become part of the control plane too.
Knowledge scope
This is startup-specific guidance in the public playbook. It is framed around the Day Zero -> Company Ready decision point and the practical trade-offs a small company faces while moving from idea to Production.
Why it matters
Remote startups often begin with BYOD because fully managed devices take time, money and effort. That can work early, but the company still needs posture visibility and a path to stronger control when customer assurance increases.
How it fits the playbook
This reference supports the Day Zero -> Company Ready stage of the startup CTO playbook. It gives the public context for the decision without exposing the deeper assessment method behind the agentic operating model.
Design considerations
- Use Company Portal and a simple Intune setup to deploy Defender where Microsoft 365 is used.
- Allow BYOD for collaboration while treating privileged access differently.
- Restrict admin access to known or compliant devices where practical.
- Define the trigger for moving privileged or sensitive work to company-owned devices.
- Plan for Cyber Essentials Plus or customer assurance requirements before they become blockers.
What good looks like
The company can move quickly with governed BYOD while knowing when stronger endpoint control and company-owned devices become necessary.

Is the company ready?
The first few months of a software business are not just about building the product. They are about creating the conditions that allow the product to be built, deployed, governed and supported without the company tripping over its own foundations.
Can we start the POC?
Before starting the POC, there is a small amount of governance that should be put in place. This is not about slowing the team down or pretending to be an enterprise. It is about creating enough shape that the first few months do not become a mess of forgotten passwords, inconsistent names, unclear decisions and accidental access.
Are we ready for a Pilot?
Before moving from POC to Pilot, the company needs a data governance baseline. This is separate from technical governance. Technical governance asks who can deploy, who can access Azure and how the environment is built. Data governance asks what information the company collects, where it is stored, why it is allowed to hold it and how it protects it.
