Data Security Governance Builder

An interactive planning document for enterprise data security: DSPM, DLP, Endpoint DLP, Sensitivity Labels, Insider Risk, External Sharing and Copilot readiness — including a live builder that generates recommendations, risk score, policy names, rollout plan and executive summary.

01

Discover

Identify where sensitive data resides, who can access it, where it is shared, and where overexposure exists.

02

Protect

Connect labels, DLP, endpoint controls, external sharing governance and an exception process.

03

Investigate & Improve

Operationalize investigation, remediation, insider risk signals, KPI and monthly governance review.

What are we building?

This is not just a DLP policy builder. It is a complete Data Security Governance workshop template. It starts with DSPM to understand data risk, continues with information protection to classify and protect data, and then applies DLP to control data movement and sensitive data usage.

The recommended approach is visibility before enforcement. Broad blocking without context creates noise, false positives, business friction and loss of user trust.

When to use it

Use it before a DLP project, before a Copilot rollout, after a data exposure incident, as part of ISO/SOC 2/GDPR readiness, or when a customer says: “We have labels, but data is still exposed.”

Recommended Data Security Architecture

Data Discovery & DSPM

Map sensitive data, overexposed data, external sharing, stale permissions, AI exposure and high-risk users.

Classification & Labeling

Define sensitivity labels, auto-labeling, container labels, encryption, visual marking and label adoption metrics.

DLP Control Plane

Create policies for Exchange, SharePoint, OneDrive, Teams, Endpoint, browser upload, USB, print, clipboard and cloud apps.

Insider Risk & Investigation

Connect alerts, user risk signals, high-severity DLP events, evidence collection and case management.

Governance Operations

Define owners, exceptions, monthly tuning, KPI, SIEM/XDR integration and legal/compliance/security review.

DLP vs. DSPM

CapabilityRole
DSPMDiscovers and prioritizes risk: where sensitive data is exposed, who can access it, and what should be remediated first.
DLPControls actions during use or sharing: email, files, endpoint activity, Teams messages and more.
LabelsClassify and optionally encrypt data, enabling consistent policy decisions across workloads.
Insider RiskInvestigates risky user behavior patterns and connects data events into case workflows.

Core principle

Discover → Classify → Coach → Enforce → Govern

The goal is not to block users. The goal is to reduce data exposure while preserving legitimate business processes.

What is DSPM?

Data Security Posture Management helps the organization understand its data exposure posture. It looks for sensitive data, excessive access, external exposure, risky sharing paths, stale permissions, and AI-related exposure before enforcement is applied.

DSPM should answer: Where is sensitive data? Who has access? Is the access justified? Is it shared externally? Could AI surface it to users who should not see it? Which issues should be fixed first?

DSPM output

  • Risk register
  • Overexposed sensitive data
  • External sharing findings
  • Priority remediation list
  • Copilot readiness gaps
  • Data owner mapping

DSPM workflow

Inventory

Discover sensitive data across SharePoint, OneDrive, Exchange, Teams and endpoints where applicable.

Exposure Analysis

Identify broad access groups, guest access, anonymous links, external domains and stale permissions.

Business Context

Map data owners, business processes, allowed external collaboration and exception requirements.

Prioritized Remediation

Fix critical issues first: secrets exposure, regulated data externally shared, HR/Legal sites with broad permissions, and AI-exposed sensitive data.

Policy Design

Translate validated risks into labels, DLP rules, endpoint controls, insider risk policies and governance review cadence.

DSPM risk patterns

  • Oversharing with Everyone / broad groups
  • External sharing of sensitive files
  • Guest users with stale access
  • Unlabeled sensitive documents
  • Credentials, secrets and API keys in files
  • Copilot/AI exposure due to excessive access
  • Privileged users accessing sensitive content

DSPM to DLP translation

DSPM tells you what is risky. DLP decides what happens when users try to move, share, upload, print or copy sensitive data.

DSPM finding: HR files are broadly accessible Governance action: remove broad permissions Label action: Confidential - HR DLP action: restrict external sharing and warn on email Operational action: monthly owner review

Production Readiness Checklist

Executive Summary Template

The objective of this engagement is to establish a phased Microsoft Purview data security governance model that combines DSPM visibility, information protection, DLP enforcement, endpoint controls, and continuous operational review. The recommended approach starts with discovery and posture assessment, prioritizes high-risk data exposure, introduces labeling and user education, and only then moves to targeted enforcement for validated scenarios.

Workshop questions for the customer

  • Which data would create the biggest risk if it leaked?
  • Where does this data live today?
  • Who is the business owner?
  • Which external sharing flows are legitimate?
  • What is the tolerance for false positives?
  • Is Copilot already enabled or planned?
  • Who handles alerts and what is the SLA?
