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.

Data Detection & Response focuses on SaaS and email exposure; Data Exfiltration Prevention adds endpoint, browser, SaaS, and GenAI controls; Nightfall Complete combines both; Complete + AI Agent Security adds IDE, CLI, MCP, Claude Cowork, and Claude Enterprise controls. The public page shows per-user yearly units but no numeric amounts. Additional discovery capacity and Developer Platform access are separate.
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
Cloud-first security teams protecting sensitive data across SaaS, email, endpoints, browsers, and GenAI applications
Organizations seeking automated remediation, employee coaching, data lineage, and context-rich investigation
Enterprises that need an upgrade path for IDE assistants, AI agents, MCP servers, and Claude 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 public numeric prices or self-service packaged DLP procurement
Teams whose primary requirement is traditional network-appliance DLP
Buyers expecting Developer Platform API entitlements or unlimited historical scanning in every base package

Key features
Central DLP policy store spanning supported Microsoft 365 workloads, endpoints, cloud apps, on-premises repositories, Fabric, Copilot, browser, and network locations
Sensitive information types, regular expressions, validation, proximity, exact data match, document fingerprinting, trainable classifiers, labels, and OCR-supported text
Policy templates, custom conditions, administrative units, workload and identity scope, simulation, and policy tuning
Data lineage, session evidence, Nyx-assisted investigation, SIEM export, and centralized policy administration
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.
No public numeric package price, payment schedule, minimum quantity, commitment term, renewal term, or implementation amount is stated
Final quote depends on user count and data volume, and stored-data capacity beyond the included allowance is optional
Endpoint and browser coverage requires agents or extensions, while SaaS and email coverage depends on supported application integrations

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.
86The product spans direct API-based SaaS and email monitoring plus endpoint and browser enforcement, and it also covers GenAI interactions, but the facts do not establish coverage for every possible application or transport path.
Detection and classification accuracy
88Employs document fingerprinting, exact data match, and trainable classifiers alongside traditional regular expressions to identify sensitive items.
87The product combines machine learning, OCR, computer vision, fingerprints, regex, dictionaries, and prompt-based detection, which gives it multiple detection methods for classification, though the facts do not provide measured accuracy results.
Enforcement controls
86Supports diverse endpoint actions including clipboard, print, USB, and network share blocks, but specific egress paths require SASE or secure browsers.
87The product offers blocking, redaction, encryption, quarantine, access restriction, alerts, justification, and self-remediation, which gives buyers multiple control types, but some GenAI cases are qualified as monitor-only or manual-remediation.
Incident operations
79Aggregates security events into Activity Explorer and integrates with Microsoft Sentinel, though advanced hunting and security copilot require separate licensing.
82The product includes centralized policy administration, session evidence, Nyx-assisted investigation, and SIEM export, which supports incident operations, but the facts do not establish full workflow automation or case orchestration.
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.
79The product includes direct API-based SaaS and email integrations and SIEM export, which supports governance and operational integration, but the facts do not establish broader ecosystem breadth or sync guarantees.
User and risk context
75Integrates with separate Insider Risk Management products to apply Adaptive Protection policies, which depends on purchasing the necessary license tiers.
77The product provides data lineage, session evidence, and justification, which helps connect actions to context and user behavior, but the facts do not establish a full identity-risk or behavior-risk model.
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.
55The product is sold by quote with no public numeric package price, payment schedule, or commitment term, and final price varies by package, application coverage, user count, and data volume, which makes total cost harder to pre-size.
These are the stored dimension rationales returned with each score. They explain the buyer conditions behind the gap without speculating about hidden model reasoning.
