Overview

Why organisations compare Proofpoint and Microsoft Purview

Microsoft Purview and Proofpoint help protect sensitive data, reduce insider risk, and support regulatory requirements. Purview is well-suited to organisations that have standardised on Microsoft 365 and want to extend data security controls across Microsoft workloads.

Organisations dealing with data that moves across a wider array of systems and channels often compare Purview with platforms that provide broad visibility across email, cloud, endpoints, and the web. This guide examines how to evaluate which approach best fits your needs.

Data Security Challenges

Three reasons organisations look beyond Microsoft Purview

Visibility beyond Microsoft environments

Purview provides strong visibility across Microsoft 365 and Azure workloads. However, many teams need a more complete view of how sensitive data is used and shared across their growing SaaS, cloud, and AI footprints.

Proofpoint unifies DLP, DSPM, and Insider Threat Management across email, cloud apps, web activity, endpoints, and AI. This helps teams see how sensitive data moves across people, systems, and channels.

Human-centric risk context

Purview combines DLP, sensitivity labels, and insider risk management to identify risky activity. Some teams need more context around user behaviour, intent, and activity that leads to data exposure.

Proofpoint combines content intelligence, user behaviour, and risk signals—not only static pattern matching—to help analysts understand what led to an event and which incidents need attention first.

Investigation-ready workflows

Purview integrates with Microsoft Defender XDR and Sentinel. But analysts may need to pull from other portals, workloads, and models to understand complex incidents and assess risk.

Proofpoint brings together alerts, user activity, policy context, and risk indicators in a unified experience that supports faster investigations and better-informed security decisions.

 

Why a leading manufacturer chose Proofpoint over Microsoft Purview for faster time to value

A Fortune 500 chemical company spent six months struggling to meet its data security goals with Microsoft Purview. After switching to Proofpoint Enterprise DLP, the team quickly found previously unseen risks, streamlined investigations, and strengthened data loss prevention.
