DLP Management
Service overview
Data classification without enforcement is documentation theater. Sitoo Advisory designs, deploys, and tunes the Data Loss Prevention controls that turn your sensitivity labels and data classification work into actual protection — across endpoints, email, Microsoft 365, and cloud workloads. Built around Microsoft Purview and integrated with the privacy program you already have or are building.
Enforcement Layer for the Data Classification You Already Did.
Most SMBs have a privacy policy, a sensitivity-label scheme, and good intentions — and zero technical enforcement preventing regulated data from leaving via personal email, USB, an unmanaged share, or an AI assistant. Sitoo Advisory closes that gap: DLP policy design, sensitivity label deployment, channel-specific enforcement (endpoint, email, cloud, generative AI), and an incident-response workflow your team can actually operate.
The Gap Between “We Classify Data” and “We Prevent Its Loss.”
Classification labels alone don’t stop data exfiltration. Default vendor DLP policies generate noise without prevention. Sitoo Advisory operationalizes DLP against your specific data inventory, regulatory drivers, and tolerance for friction — tuned for your environment, not a 50,000-seat reference architecture.
Is This Right for Your Business?
What We Fix
Labels without enforcement
Your sensitivity labels exist in the Microsoft 365 admin center. Users see them. Nothing actually prevents an “Internal Only” document from being attached to a personal Gmail or downloaded to an unmanaged laptop.
Default DLP policies generating noise, not prevention
Vendor templates flag every credit-card-like number, every birth-date string, every potentially-sensitive document. The alert queue is unworkable; your team triages nothing; real exfiltration hides in the noise.
No coverage for the channels that matter
You enabled email DLP but not endpoint DLP. Or endpoint DLP but not cloud DLP. Or none of the above for the new generative AI tools your team started using last quarter.
No incident workflow when DLP alerts fire
An alert fires. Nobody knows whether it’s real, who triages it, what the escalation path is, or whether the underlying activity is a real exfiltration event or a legitimate business need that DLP overcaught.
Deliverables & Scope
Every engagement produces defined, tangible deliverables. No open-ended hours.
DLP Strategy & Policy Design
Documented policy hierarchy, label taxonomy, in-scope data classes, channel coverage matrix, exception and override workflow — sized for your environment.
Sensitivity Label Architecture (Microsoft Purview Information Protection)
Label scheme aligned to your data classification, sublabels for jurisdiction or regulatory tag, auto-labeling rules, encryption and rights-management policies.
Endpoint DLP Deployment & Tuning
Endpoint policy rollout (Windows / macOS), monitor-mode validation, blocking-mode cutover, false-positive triage cadence, exception governance.
Email & Cloud DLP Policies
Exchange Online / Outlook DLP, Teams chat DLP, OneDrive / SharePoint DLP, third-party app coverage where supported, generative-AI prompt protection.
Incident Triage Workflow & Runbook
Documented alert classification, severity-tier escalation, business-justification override flow, regulatory notification trigger points for confirmed exfiltration.
DLP Effectiveness Report & Tuning Plan
30-day post-deployment measurement of alert volume, true-positive rate, blocked vs. allowed actions, and a tuning roadmap for the next quarter.
How the Engagement Works
Data & Channel Discovery
We map your regulated data inventory (or build one), identify the channels carrying it (email, endpoints, cloud, AI tools), and confirm your tooling license posture (Purview, E5, third-party).
Policy Design & Monitor-Mode Deployment
Labels, policies, and rules deployed in monitor mode. We watch the alert stream with your team, refine thresholds, eliminate noise, and tune before any blocking goes live.
Enforcement Cutover & Incident Workflow
Blocking-mode cutover by channel, runbook training for your triage team, 30-day effectiveness measurement, and a maintenance plan for ongoing policy tuning.
What You Will Have at Engagement End.
Working DLP across the channels that matter
Endpoint, email, and cloud DLP policies live and enforcing — not just licensed and dashboarded. Generative-AI prompt protection where licenses allow.
Sensitivity labels with teeth
Labels that actually drive encryption, rights management, and DLP enforcement — not metadata that exists only in the admin center.
An incident workflow your team can run
Documented triage runbook, severity tiers, escalation paths, override flow, and notification triggers — so alerts produce action, not noise fatigue.
Demonstrable technical safeguards for audit
The control evidence auditors and insurers increasingly demand under SOC 2 CC6.7, HIPAA Security Rule §164.312(e), GDPR Art. 32, and PCI DSS Req. 3–4.
