Siberson Veriket Data Classification: Building a KVKK-Ready Data Policy for Turkey

Why Turkey Needs Policy-Driven Data Classification Now

Turkey’s Personal Data Protection Law (KVKK) and its secondary regulations place concrete, auditable obligations on organizations handling personal data: identify it, protect it proportionately, retain it only as long as necessary, and prove compliance. Without a persistent sensitivity label attached to each file and email, controls remain guesswork at enforcement points. Siberson Veriket Data Classification closes this gap by embedding machine-readable sensitivity into content at creation and during handling—so KVKK compliance becomes systematic, region-aware, and provable.

Siberson Veriket Data Classification turns your governance policies into automatic labels that travel with data across endpoints, email, cloud, and storage—making downstream DLP and security tools deterministic rather than inferential.

KVKK and Policy Foundations

KVKK aligns conceptually with GDPR but has its own definitions, consent rules, and enforcement posture. A practical classification policy for Turkey should mirror KVKK’s core constructs while remaining usable for employees and interoperable with security tools.

Key KVKK Concepts to Reflect in Classification

Personal Data vs. Special Categories: Special categories include data on race, ethnicity, political opinion, religion, association membership, health, sexual life, criminal convictions, and biometric/genetic data—demanding heightened protection.
Processing Legality: Explicit consent or other legal bases (e.g., contractual necessity, legal obligation) govern collection and use; classification should capture consent state where applicable.
Data Minimization and Retention: Limit processing to purpose and store only as long as required; labels can carry retention attributes to guide lifecycle handling.
Transfer Restrictions: Domestic and cross-border transfers require safeguards; labels should include export permissions to enable control at egress.

A “labels-only” program is insufficient. Labels must be operationalized: read and enforced by DLP, email security, CASB, and access controls—otherwise policy intent won’t translate into real protection.

From Regulation to Reality: The Veriket Policy Engine

Veriket translates KVKK-aligned rules into consistent labels and attributes that downstream systems can act on.

How Veriket Works

Structured Policy Taxonomy: Group rules by Privacy (KVKK/GDPR), Finance, Legal, IP, PCI—simplifies ownership and reporting.
Region-Aware Enforcement: Run KVKK policies for Turkish users/data in parallel with GDPR or other regimes without conflict.
Deterministic Outcomes: Map detections to standard labels (e.g., Public, Internal, Confidential, Restricted) and governance attributes.
Detection Methods: AI-assisted content understanding, keyword/rule libraries, Regex for PII (e.g., T.C. Kimlik No, IBAN), contextual validation to reduce false positives.
Lifecycle Governance: Version, test in audit mode, deploy, and maintain a complete audit trail of changes and classification events.

Recommended KVKK-Aligned Label Taxonomy

Adopt a simple, teachable base taxonomy with optional governance attributes to capture KVKK specifics.

Public: Information intended for external use; no personal data.
Internal: Business content for employees/approved partners; may include non-sensitive operational details.
Confidential – Personal Data: Contains personal data under KVKK; restrict external sharing and apply retention/export guidance.
Restricted – Special Categories: Contains special categories of personal data; highest control level, limited access, strong transfer restrictions.

Governance attributes carried with the label:

Personal Data Type: Personal | Special Category
Consent Status: Explicit | Other Legal Basis | Not Required
Retention Period: e.g., 2y, 5y, case-specific
Export Permission: Domestic only | EU adequate | Approved third country | Prohibited without DPA/SCC-equivalent safeguards
Jurisdiction Validity: KVKK, optionally GDPR if dual applicability

Best practice: Keep 4–5 primary labels and express nuance through attributes. This maximizes user adoption and preserves enforcement precision.

User Experience and Adoption

Veriket integrates into everyday tools to keep policy visible and enforceable without friction.

Office and Email: Labels in Word/Excel/PowerPoint ribbons; email compose prompts; attachments inherit or are assessed.
Endpoints: Right-click menus on Windows/macOS/Linux/Pardus; batch labeling; silent auto-labeling for high-confidence patterns.
Markings: Headers, footers, watermarks communicate sensitivity; users receive just-in-time guidance and, where configured, must justify downgrades.

Enforcement: Classification-Driven DLP

Veriket writes standardized labels and GUIDs into file metadata so DLP engines can act deterministically.

Native synergy with Siberson Verikor DLP; vendor-agnostic integrations validated with Forcepoint, Broadcom/Symantec, McAfee/Trellix, Microsoft, Digital Guardian, Trend Micro, Zecurion, Safetica.
If label = Restricted – Special Categories → Block external email; allow only to whitelisted domains with encryption and approval.
If label = Confidential – Personal Data and export permission != approved → Block cloud upload; require DPO approval override.
Unlabeled files leaving endpoint → Quarantine or force user to classify before send.

Implementation Blueprint for Turkey

Map KVKK obligations to label outcomes: consent capture, retention, export, special categories handling.
Align with ISO 27001 control 5.12 (information classification) if applicable.
4-level sensitivity + governance attributes listed above.
Decide visual markings and user prompts.
Start in audit mode; validate detections for national identifiers (T.C. Kimlik No), IBAN, phone, address, health terms.
Pilot with high-value groups (HR, Legal, Customer Ops, Health/Insurance).
Map Veriket label GUIDs into DLP; create label-based rules for email, web, endpoint, and cloud.
Set progressive actions: warn → notify → encrypt → block.
Track label distribution, special category volume, retention adherence, and cross-border transfer attempts.
Export audit packs for KVKK inquiries and board oversight.
Train users with in-context prompts; tighten policies as confidence grows.
Review exceptions quarterly; prune legacy rules and keep taxonomy stable.

What Good Looks Like: Controls-to-Evidence Traceability

Every document/email carrying a persistent label + attributes.
DLP policies triggering primarily on labels, not just content heuristics.
Dashboards showing percentage of data estate covered and trend of special categories over time.
Exportable audit evidence: classification logs, policy versions, and incident outcomes.

Outcomes and ROI

Lower DLP Noise: Label-driven enforcement reduces false positives by anchoring actions to known sensitivity.
Audit Readiness: Time-stamped classification and policy-change logs accelerate KVKK, ISO 27001, and GDPR audits.
Behavioral Lift: Visible markings and prompts improve day-to-day handling decisions, decreasing accidental leakage.
Cross-Border Control: Attribute-driven export permissions simplify lawful transfer governance.

Customer Snapshot

A Turkish universal bank deployed Veriket across endpoints and Office with a four-level taxonomy and KVKK attributes for consent and export. Their existing DLP consumed labels as the primary condition across email and web. Within one quarter, the SOC reported a significant reduction in false positives and faster incident triage; compliance teams produced clean evidence packs for KVKK reviews without ad-hoc data hunts.

Getting Started Checklist

[ ] Approve a 4-level taxonomy and governance attributes (consent, retention, export, jurisdiction)
[ ] Inventory sensitive processes (HR, Payroll, Claims, Customer Support) and prioritize pilots
[ ] Configure Veriket policies; run in audit mode for 2–4 weeks
[ ] Map label GUIDs into DLP; enable label-based conditions
[ ] Define visual markings and downgrade justification rules
[ ] Establish reporting cadence and audit export templates

FAQ

Veriket provides endpoint coverage for Linux and the Pardus distribution, enabling consistent labeling, user prompts, and metadata persistence across public sector and mixed-OS estates.

Yes. Veriket’s region-aware enforcement activates KVKK controls for Turkish users/data and GDPR rules for EU contexts in parallel, preventing policy conflicts while maintaining a single global taxonomy.

Configure enforcement strength: require justification for downgrades, auto-correct labels on detection, or block send/save until correct. Admins can review justifications in audit logs.

No. Veriket writes standard labels and GUIDs that your existing DLP can consume. Many customers retain Forcepoint, Broadcom, McAfee/Trellix, Microsoft, or adopt Siberson Verikor DLP for native synergy.
