Data Loss Prevention for PII/PHI/PAN, IP & Regulated Content
Data Loss Prevention (DLP) prevents sensitive data from being exposed, misused, or exfiltrated—on endpoints, in SaaS, across web/email, and inside clouds/data centers. SolveForce builds DLP that is accurate, actionable, and auditable: you get clear policies, low false positives, safe controls (block/quarantine/watermark/encrypt), and evidence that satisfies audits.
Where DLP fits in the SolveForce model:
🔒 Security (Semantics) → Cybersecurity • 🧠 Analytics/Automation → SIEM / SOAR
🔑 Identity & Access → IAM / SSO / MFA • 🔐 Zero Trust → ZTNA • SASE
📱 Device trust → MDM / UEM • 🛡️ Endpoint → EDR / MDR / XDR
🪪 Keys & certs → Key Management / HSM • PKI • Encryption
☁️ Cloud & DC → Cloud • 🖧 Fabric → Networks & Data Centers
🎯 Outcomes (What SolveForce DLP Delivers)
- Real control, low noise— accurate detection with policy actions you can trust.
- Coverage where users really work— endpoints, SaaS, web/email, storage, and collaboration.
- Inline Zero-Trust— enforce least privilege for data: watermark, read-only, redact, encrypt, or block.
- Audit-ready— full timelines, artifacts, decisions, and approvals for PCI/HIPAA/ISO/NIST/CMMC.
- Measurable improvement— fewer incidents, lower “shadow IT” risk, better user behavior.
🧭 DLP Scope (Where We Enforce)
- Endpoints— copy/paste, screenshots, print, removable media, local exports.
- Email— content/attachment inspection; quarantine/purge; tag/watermark.
- Web / SWG— uploads to websites, file shares, unsanctioned SaaS; restrict per domain/category. → SASE
- SaaS / CASB— sanctioned SaaS (Drive/SharePoint/Box/Slack/etc.): share controls, watermark, read-only, external collaborator gates. → SASE
- Cloud storage & objects— buckets/containers/objects (SSE-KMS, tags, server-side encryption). → Cloud • Encryption • Key Management / HSM
- Data centers— file servers, NAS/SAN zones; microseg protections. → Networks & Data Centers
- Collaboration— link expiries, classification banners, block public links, AIP/labels alignment.
- Printing/Scans— watermark, logging, or deny for sensitive classes.
🧱 Policy & Classification (How We Know What to Protect)
Data Classes (examples)
- PersonalPII (names, addresses, SSNs, national IDs, phone, email).
- HealthPHI (diagnoses, treatment codes, records).
- PaymentPAN, CVV, IBAN, routing/account numbers.
- Financial & HRpayroll, salary bands, tax docs, performance reviews.
- IP/Trade Secretssource code, models, designs, research.
- Legal/Regulatoryexport-controlled, attorney-client, investigations.
Detectors (combined for accuracy)
- Validators/regexwith checksums (e.g., Luhn for card numbers).
- Dictionaries & keyword proximity(industry terms near PII tokens).
- Document fingerprints(exact/near-exact match of templates/contracts).
- File-type & structure(PDF, CSV, office formats; embedded content).
- ML/NLP classifiers(contextual cues for IP/PHI/PII where patterns are weak).
- Labels/metadata(AIP/Sensitivity labels, headers/footers, custom tags).
Best practice: build tiers (Public, Internal, Confidential, Restricted) and map them to actions per channel.
🧰 Controls (What Happens When We Detect)
- Block / Quarantine— prevent send/upload; quarantine a copy for review.
- Watermark / Read-Only— watermark documents; open in read-only; disable download on SaaS.
- Redact / Mask— remove or obfuscate sensitive fields (e.g., partial PAN).
- Encrypt— require S/MIME, TLS, or server-side encryption with customer-managed keys for stored objects. → Encryption • Key Management / HSM
- Coach— just-in-time warning with user justification option for borderline cases.
- Isolate— open the destination in Remote Browser Isolation (RBI) or restrict to managed device via ZTNA. → ZTNA
- Ticket & Notify— open case, notify data owner/legal/IR; require manager/legal approve for release.
Inline where it matters
- Endpoint agentacts before content leaves the device.
- SWG/CASB/SSEacts on web/SaaS flows at edge PoPs. → SASE
- Email gatewayquarantines or rewrites with encryption/watermark.
🔒 BYOD, Contractors & Partners (Practical Zero Trust)
- BYODrequire work profiles/app containers; apply per-app VPN; enforce DLP only in work container. → MDM / UEM
- Contractors/partnersclientless ZTNA with read-only/watermarks; prevent download for unmanaged devices. → ZTNA
- Admin accessPAM elevation with session recording when data is sensitive. → PAM
🧩 Integrations (Make DLP Part of the System)
- Identity — ABAC/RBAC, SSO/MFA, group-based exceptions. → IAM / SSO / MFA
- Device — posture gates (encryption on, EDR healthy, OS at minimum). → MDM / UEM • EDR / MDR / XDR
- Network — SD-WAN/NAC for microseg/quarantine; block/shape exfil channels. → SD-WAN • NAC
- Cloud — on-ramps and storage controls; object tagging/auto-encrypt. → Direct Connect • Cloud
- Keys & Certs — customer-managed keys (CMK), envelopes, JWKS rotation. → Key Management / HSM • PKI
- Analytics/IR — send events and artifacts to SIEM; trigger SOAR playbooks for review/contain. → SIEM / SOAR
📐 SLO Guardrails (Experience & Safety You Can Measure)
| Metric | Target (Recommended) | Notes |
|---|---|---|
| Inline decision latency (web/SaaS) | ≤ 50–150 ms at edge PoP | Keep UX crisp |
| Endpoint decision time | ≤ 250–500 ms | Local cache of policies |
| False positive rate | ≤ 3–5% | Use fingerprints + validators |
| True positive precision (priority) | ≥ 92–95% | After tuning |
| Incident review SLA (Sev-2) | ≤ 24 h | Business day triage |
| Evidence completeness | 100% for Sev-1/2 | Timelines + artifacts |
| Coverage (channels/policies online) | ≥ 95% | Enforced & reporting |
🧪 Tuning Loop (Keep Signal High, Noise Low)
- Pilot with coaching → gather user justifications, refine rules.
- Add validators/fingerprints → reduce regex-only hits.
- Split policies by channel → stricter on web/email than internal shares.
- Stage to block → after two-week stable precision on coached rules.
- Review exceptions weekly → retire stale exceptions; enforce labels.
- Measure & publish → false/true positive trends, incident closure time, user behavior improvements.
🧾 Compliance Mapping (Examples)
- PCI DSS— PAN handling; masking/redaction; encryption at rest/in transit; logging.
- HIPAA— PHI protection; minimum necessary; audit controls.
- ISO 27001 / 27002— classification, handling, transfer controls, monitoring.
- NIST 800-53/171— AC, AU, MP, SC families; boundary protections and monitoring.
- CMMC— CUI handling; access, audit, and media protections.
Evidence streams to SIEM with WORM/immutability options and case IDs. → SIEM / SOAR
📦 Data Architecture Aids (Make DLP Easier)
- Label at creation(AIP/Sensitivity labels) in authoring tools; default to Internal.
- Tokenizehigh-risk fields (PAN/PII) upstream; store surrogates in app DBs. → Key Management / HSM
- Encrypt by default(SSE-KMS, TDE, field encryption) with customer-managed keys. → Encryption
- Watermarksensitive exports; store immutable logs of data actions.
🧰 Implementation Blueprint (No-Surprise Rollout)
- Inventory data flows — where data is created, stored, moves, and exits.
- Define classes — PII/PHI/PAN/IP; map to label tiers and actions.
- Select channels — endpoint, email, SWG, CASB, storage; start with the highest-risk flows.
- Pilot policies — coach-only; collect justifications; measure precision/recall.
- Stage to enforce — block/encrypt/watermark for true-positives; keep coaching for gray areas.
- Wire analytics & IR — SIEM dashboards; SOAR review & containment playbooks.
- Educate — short, specific user prompts; show why an action was blocked and how to remediate.
- Audit packs — policy docs, policy→action maps, sample incidents, evidence exports.

Key terms in plain language
Open a term for a concise explanation of language used on this page.
Latency
The time it takes data to travel between two points. Lower latency improves voice, video meetings, cloud applications, gaming, and other real-time services.
Service-Level Agreement (SLA)
A provider’s written commitment covering service targets such as availability, response time, repair time, and sometimes financial credits when commitments are missed.
SD-WAN
Software-defined wide area networking. It manages multiple connections and chooses paths based on application needs, performance, and policy to improve resilience and control.
VPN
A virtual private network creates an encrypted connection across another network, commonly allowing remote users or offices to access private resources securely.
Software as a Service (SaaS)
Software accessed as an online service instead of being installed and maintained entirely on the customer’s own computers or servers.
Cybersecurity
The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.
Zero Trust
A security model that does not automatically trust a user or device because of its location. Access is continuously verified and limited to what is necessary.
SASE
Secure Access Service Edge combines networking and security capabilities in a cloud-delivered architecture so users and locations can receive consistent policy wherever they connect.
