End-to-end data security in five steps

Mark Hindson
Solution Architect (Security) - Data#3

From the new challenges emerging with AI, through to internal/external threats and keeping pace with regulatory change, the world of data security is evolving faster than ever. For many organisations, maintaining consistency across cloud and on-premise environments are daily challenges.

But it doesn’t have to be.

At Data#3, we help organisations across Australia and the Pacific Islands achieve complete data security, powered by Microsoft. Our five-step Information Protection Framework guides you from discovery to control, ensuring your entire environment from endpoints to applications is secure, compliant and easy to manage.

 

A framework focused on outcomes

Our five-step framework was developed around a single principle: security should enable progress, not slow it down.

Aligned with National Institute of Standards and Technology (NIST) and ISO 27001, this approach ensures your organisation meets the highest compliance standards without impacting the user experience or operational performance.

Whether you’re an enterprise organisation, a public sector agency, or a commercial business, the framework provides a clear roadmap to strengthening your security profile, from classification to live controls.

Step 1: Define your classification framework

Our first step is to provide clarity over how to classify your organisation’s data.
We review your existing policies and develop a tailored Information Classification Policy that aligns with your organisation’s governance requirements.

This creates a strong foundation for storing and moving data safely and compliantly, while making sure your people know how to protect information consistently.

Outcome: A solid foundation for governance and user accountability.

Step 2: Identify information assets

You can’t protect what you can’t see. Using Microsoft Purview, Data#3 identifies sensitive data across Microsoft 365 and network file shares, creating visibility into where it lives, how it moves, and who is handling it.

Outcome: A clear picture of your data landscape, supported by a discovery report and asset register.

Step 3: Classify information

Once you can see your data, the next step is to label it, track it and automate its protection.
We implement Microsoft Purview labels and policies that enable consistent classification and security, without interrupting how your people work.

Outcome: Automated data protection that’s simple for users and seamless for IT.

Step 4: Assess existing controls

Next, we evaluate your current data loss prevention (DLP) and governance controls to understand where gaps exist.

This maturity assessment helps you prioritise improvements and align business and technical requirements with Microsoft capabilities.

Outcome: A roadmap for improvement, ensuring your data security evolves with your business.

Step 5: Implement and optimise controls

Finally, we turn strategy into action.

Our team deploys and fine-tunes Data Loss Prevention (DLP) controls using Microsoft Purview and Defender, ensuring protection that’s both measurable and user-friendly.

Outcome: Live, active controls that strengthen your resilience and compliance.
