DLP solutions for US businesses

Loss prevention through Purview, so that sensitive data stops leaving by routes nobody intended.

This stops data leaving, whether somebody meant it to or not. A Social Security number typed into an email. Patient records uploaded to a consumer cloud account. Source code sent to a personal address. Financial data shared with somebody outside. We deploy Purview loss prevention across mail, the Microsoft applications, the endpoints themselves and your other subscription software, with policies tuned to whichever regulations actually apply to you, whether HIPAA, GLBA, NYDFS Part 500, PCI, or the state privacy laws. Delivered remotely.

DLP coverage scope

Six channels DLP monitors and controls.

This only works when every route sensitive data could take is covered. We deploy across six of them, because a gap in any single one means the policy fails on precisely the day it was supposed to matter.

Email DLP

Outbound email scanned for sensitive patterns: payment card numbers, Social Security numbers, patient identifiers, financial figures, source code. Block, encrypt, or warn based on policy. Email is the most common data-leakage vector.

M365 apps DLP (SharePoint, OneDrive, Teams)

Sensitive files sitting in SharePoint and OneDrive either flagged or prevented from being shared outside. Teams messages and the files inside them scanned. Notifications when something goes external. Labels inherited properly rather than lost along the way.

Endpoint DLP

Purview Endpoint DLP watches sensitive data being copied to USB, printed, uploaded through the browser to consumer cloud services, pasted to unallowed destinations, or accessed by restricted apps. Block or warn based on policy, with the device onboarding piggybacking on Defender for Endpoint.

SaaS app DLP

The cloud application controls extend this out to software from other vendors, covering Salesforce, Box, Dropbox, Google Workspace, ServiceNow and Slack. Sensitive data being uploaded, downloaded or shared all gets flagged.

Sensitivity labeling

Labels applied by hand and applied automatically, running from public through confidential to highly confidential. Each label travels with the document itself, carrying the encryption, the watermark and the access restrictions with it. Classification handled automatically through Purview.

Insider risk monitoring

The insider risk side detects the behavior patterns that matter: somebody hoarding data, access that looks unlike them, and the pattern that appears when a person has already decided to leave. There is an investigation workflow so HR and security can work the same case together rather than separately.

Why US businesses route DLP through us

Four reasons clients pick our DLP work.

US-regulation-tuned policies

Purview ships built-in sensitive information types for the identifiers US policies turn on: Social Security numbers, ITINs, ABA routing numbers, US bank account and driver's license numbers, and payment card data. We map those to your actual obligations, HIPAA for patient data, GLBA and FTC Safeguards for customer financial data, PCI DSS for card scope, CCPA/CPRA and state privacy laws for consumer personal information, so the policy reflects what your regulators actually ask about.

Low false-positive operating model

This fails when the noise buries the team. Every policy gets piloted before it enforces anything, the thresholds get tuned, the patterns known to be fine get suppressed, and people are educated before anything starts blocking them outright. What you end up with are alerts that mean something and blocks that were warranted.

Integrated with Sentinel and security operations

The alerts feed into Sentinel like everything else. Analysts triage them inside the agreed response time. False positives loop back into tuning the policy rather than being ignored. This becomes part of how security actually operates rather than a parallel system nobody opens.

Phased rollout: detect, warn, block

These rollouts succeed in three phases and fail when anybody skips one. First watch only, establishing what is actually happening. Then warn people, educating without blocking anything. Then enforce. The sequencing is deliberate so that nobody has their work interrupted on the first morning.

DLP best-fit profiles

Six business profiles where DLP is essential.

Financial services

Customer financial data, transaction records, KYC documents. GLBA, FTC Safeguards and NYDFS Part 500 data-handling controls.

Healthcare

Patient records, medical history, clinical data. HIPAA Privacy and Security Rule safeguards, state health privacy laws.

Retail (PCI scope)

Card data, customer records and transaction logs. Reducing what falls inside PCI scope in the first place.

Professional services

Confidential client documents, deal material and intellectual property. Reducing exposure both to business email compromise and to somebody sharing the wrong thing by accident.

Manufacturing

Proprietary designs, formulations, customer lists. IP protection from insider exfiltration, CMMC where defense contracts apply.

Education

Student records, exam content, research data. FERPA data-handling, state privacy law alignment.

How a DLP engagement runs

Four phases from policy design to enforced DLP in 8-12 weeks.

DLP rollout sequencing matters. Skip phases and you get either alert fatigue (everything blocked, business disrupted) or alert apathy (nothing blocked, policy ignored). We sequence to land at sustainable enforcement.
  1. 1

    Sensitive data discovery and policy design

    2-3 weeks

    Workshops to identify sensitive data categories. Sample-data classification scan. Policy design: what to detect, what to do (audit, warn, block). Output: written DLP policy framework.

  2. 2

    Monitor-only pilot

    2-3 weeks

    DLP policies deployed in audit-only mode. Real traffic monitored without user-facing impact. Baseline false-positive rate measured. Policies tuned before user-facing rollout.

  3. 3

    Warn-mode rollout

    2-3 weeks

    User-facing warnings activated. Users see "this looks sensitive, are you sure?" prompts. User education campaign rolled out. Adoption and behavior change measured.

  4. 4

    Block-mode and ongoing

    2-3 weeks plus continuous

    Block enforcement for highest-sensitivity policies. Continuous tuning. Quarterly review of false-positive rate. Annual policy refresh as the data landscape evolves.

DLP FAQ

What buyers ask before adopting.

M365 E3 includes basic DLP for Exchange Online, SharePoint, and OneDrive. M365 E5 (or the M365 E5 Compliance add-on) adds endpoint DLP, advanced classifiers, Insider Risk Management, and Microsoft Defender for Cloud Apps. We confirm entitlement against your tenant during scoping, and frequently find capability the organization already owns and has never enabled.

Yes. Block actions are configurable per policy. A common pattern: warn-only for general users, block plus audit for confidential-labeled documents, block for regulator-defined sensitive data. Override-with-justification is an option for legitimate business cases, and it records a decision rather than just stopping work.

Purview ships built-in sensitive information types covering the identifiers US policies most often turn on, including US Social Security numbers, Individual Taxpayer Identification Numbers, ABA routing numbers, US bank account numbers, US driver's license numbers, US passport numbers, and payment card numbers. Custom classifiers cover organization-specific patterns such as customer account formats or project code names. We tune both during scoping.

It implements a meaningful slice of the Security Rule's technical safeguards for data in motion: detecting and blocking protected health information leaving through email, cloud sharing, or endpoints, and producing the audit evidence a HIPAA security risk analysis expects. Microsoft makes a Business Associate Agreement available covering Microsoft 365 services; our job is the controls and evidence, your compliance advisors own the interpretation.

Endpoint DLP rides on the same Defender agent stack that is already on the device, so there is no second heavyweight agent. Classification runs on file create and modify rather than continuously re-scanning, which keeps the overhead modest in practice. We monitor performance during the pilot phase so any issue surfaces before enforcement does.

Standard patterns (payment cards, Social Security numbers) have well-tuned default classifiers. Custom patterns require tuning. The monitor-only pilot phase exposes the false-positive rate so we can tune before enforcement, and the goal is a rate low enough that every alert is worth a human look.

Yes, via OCR-based classification in Purview. Screenshots of card numbers, photos of ID documents, and scanned statements are detected by OCR-then-classify. It is computationally heavier than text scanning, so we configure it for the right balance of coverage and performance.

DLP alerts feed Microsoft Sentinel. Analysts triage within SLA, and the false-positive feedback loop runs back into policy tuning. DLP becomes part of the security operating model rather than a parallel system nobody monitors, which is the usual failure mode of standalone DLP purchases.

Purview Insider Risk Management detects risky behavior patterns: data hoarding before resignation, unusual access, exfiltration attempts. It includes an investigations workflow built for HR and security collaboration. We deploy IRM as part of full DLP engagements for clients who need it, and it is the natural next step once channel DLP is stable.

Operationally, yes. Those laws assume you know where consumer personal information lives, who can access it, and that it does not leak into channels you cannot govern. Classification tells you where it is, DLP controls where it can go, and the audit trail evidences both. The legal analysis of which state laws apply to you belongs with counsel; the controls that make compliance executable are what we build.

Typically 8-12 weeks to sustainable block-mode on the highest-sensitivity policies, moving through discovery, monitor-only, and warn phases first. Enforcement on day one is possible technically and almost always a mistake operationally, because it blocks legitimate work before anyone has seen what normal looks like.

Scoped per engagement and quoted on request, driven by channel coverage (email only versus the full six), user count, and whether steady-state tuning stays with us. The scoping call is free and produces a written phased rollout proposal either way.
