DLP is acquired through containing Microsoft licenses and, for selected extended data-security scenarios, pay-as-you-go billing. Microsoft 365 E3 supplies core Exchange Online, SharePoint Online, and OneDrive DLP. Microsoft Purview Suite adds advanced Purview capabilities to an eligible E3 base, while Microsoft 365 E5 contains the Purview Suite capabilities within a broader productivity and security bundle. Microsoft requires a license for each user benefiting from user-based protection. Browser, network, non-Microsoft, and at-rest scenarios can add Azure consumption charges and deployment prerequisites.
Microsoft 365 E3 core DLP: Obtain core DLP for Exchange Online, SharePoint Online, and OneDrive for Business through Microsoft 365 E3. E3 is a broader suite and does not provide the full Endpoint, Teams, Copilot, risk-adaptive, browser, network, or extended incident scope by itself.
Microsoft Purview Suite: Add advanced user-based Data Loss Prevention and the rest of the Purview Suite to an eligible Microsoft 365 E3 base or Office 365 E3 plus Enterprise Mobility + Security E3 base.
Microsoft 365 E5: Obtain all Microsoft Purview Suite capabilities through a broader Microsoft 365 productivity, identity, endpoint, threat-protection, analytics, and compliance plan. With-Teams and no-Teams states are separate bundle offers, not DLP plans.
Microsoft Purview pay-as-you-go data security: Link the Microsoft 365 tenant to an Azure subscription for supported at-rest or in-transit Information Protection and DLP policies. At-rest protection is metered by protected assets and in-transit protection by policy-scoped requests; the current public table did not expose numeric U.S. rates.
DLP Transform Tier 1 and Tier 2 are the current exact-target offers. Tier 1 is positioned for cloud applications and endpoints; Tier 2 adds published email coverage and multi-channel operations. Numeric direct prices, priced units, payment timing, exact commitments, renewals, minimum quantities, implementation fees, and service fees are not published for either tier. A broader AWS Information Protection package has a public 500-user annual amount, but it also includes ITM and SaaS isolation and is therefore retained only as a related purchase path.
Proofpoint Information Protection on AWS Marketplace: A broader AWS Marketplace Information Protection package for 500 users that contains DLP Transform together with endpoint DLP, cloud DLP, SaaS isolation, and Insider Threat Management. It is not an exact Tier 1 or Tier 2 offer and does not set the target starting price.
Microsoft 365 organizations standardizing DLP policy across email, files, collaboration, endpoints, Fabric, and eligible Copilot workflows
Enterprises requiring central policy administration, audit telemetry, alerts, Defender XDR correlation, and Microsoft Sentinel integration
Programs that need exact data match, document fingerprinting, trainable classifiers, OCR-supported detection, sensitivity labels, and custom sensitive information types
Large enterprises with sensitive or regulated data moving across endpoints, SaaS, cloud, email, web, collaboration, and AI applications
Security teams that want content inspection combined with user behavior, intent, activity, and threat context
Organizations replacing siloed endpoint, cloud, and email DLP operations with centralized policy and incident workflows
Not for
Buyers requiring one standalone DLP SKU and one deterministic public price for every channel
Non-Microsoft-first environments unwilling to deploy Microsoft identity, Edge, supported SASE, scanner, or cloud-app integrations
Teams that cannot stage policies in simulation, tune classifiers and exceptions, train users, and operate alerts
Buyers requiring transparent self-service pricing or a permanent free edition
Small teams without resources for policy design, deployment, integration, investigation, and tuning
Buyers expecting DSPM, Adaptive Email DLP, Email DLP and Encryption, ITM, CASB, and services to be automatically included in every DLP tier

Endpoint controls for clipboard, print, USB, network share, restricted apps, browser upload, and other supported egress activities
DLP Transform Tier 1 for cloud applications and endpoints and Tier 2 for email, cloud applications, and endpoints
Sensitive-content inspection across managed and unmanaged endpoints, cloud apps, email, collaboration, web uploads, and GenAI workflows
Regex, OCR, indexed and exact data matching, Microsoft Information Protection classification, LLM-based classifiers, and data-lineage signals
Adaptive policies informed by user behavior, intent, activity, and risk scores
Block, redact, alert, guided-user, encryption, and incident-response controls where supported by the relevant channel
Cons
Licensing is feature- and workload-specific
each benefiting user needs the appropriate entitlement, and equivalent education, government, frontline, Office 365, and standalone workload rights differ.
The USD 12 public amount belongs to Microsoft Purview Suite, not DLP alone, and the eligible base license adds cost.
Direct numeric tier prices, priced units, payment timing, exact commitment, renewal rules, minimum quantities, implementation fees, and services prices are not public
Tier 1 does not publish email in its summary
buyers needing email should validate Tier 2 and the relationship to separately marketed Email DLP and Encryption

Channel and data coverage
85The product spans supported Microsoft 365 workloads, endpoints, cloud apps, on-premises repositories, Fabric, Copilot, browser, and network locations, which gives it broad channel reach for Microsoft-centered environments.
81Tier 1 includes cloud applications and endpoints, while Tier 2 adds email to cloud applications and endpoints, and the product facts also reference collaboration, web uploads, and GenAI workflows, which gives broad channel coverage with tier-specific boundaries.
Detection and classification accuracy
88Employs document fingerprinting, exact data match, and trainable classifiers alongside traditional regular expressions to identify sensitive items.
86Reduces identification errors by leveraging diverse inspection capabilities including OCR, exact data matching, and LLM classifiers, which must be tuned to prevent configuration-driven false rates.
Enforcement controls
86Supports diverse endpoint actions including clipboard, print, USB, and network share blocks, but specific egress paths require SASE or secure browsers.
83Block, redact, alert, guided-user, encryption, and incident-response controls are available where each channel supports them, enabling graduated responses rather than a single block-or-allow outcome.
Incident operations
79Aggregates security events into Activity Explorer and integrates with Microsoft Sentinel, though advanced hunting and security copilot require separate licensing.
81Centralizes security alert management and search within a unified console, but security teams must allocate dedicated resources for continuous policy tuning and triage.
Governance and integrations
82Central DLP policy administration integrates with Information Protection labels and classifiers, Microsoft 365 audit telemetry, Defender XDR, and Microsoft Sentinel for organizations already standardized on those Microsoft governance and security surfaces.
82Integrations with Microsoft, Okta, Splunk, ServiceNow, SIEM, SOAR, Teams, and native Proofpoint products, plus regional privacy controls, support enterprise identity, ticketing, and security-operations governance where those connectors are deployed.
User and risk context
75Integrates with separate Insider Risk Management products to apply Adaptive Protection policies, which depends on purchasing the necessary license tiers.
86Adaptive policies use user behavior, intent, activity, and risk scores, which gives the product a user-and-risk context layer that can inform DLP decisions beyond static content rules.
Support and total cost
60Lacks a standalone license, requiring organizations to purchase broad suites like M365 E5 or add-ons alongside possible Azure pay-as-you-go charges.
50Both DLP Transform tiers require a custom quote with no published amounts, units, or service inclusions, and Advisory, Applied, managed, and professional services are marketed separately, so buyers cannot validate support scope or total cost without vendor engagement.
These are the stored dimension rationales returned with each score. They explain the buyer conditions behind the gap without speculating about hidden model reasoning.
