Data Retention Policy
1. Purpose & Scope
This policy establishes the mandatory standards governing the retention, storage, review, and secure disposal of all data generated, processed, or stored by Aevum Zenth Conglomerate and its 400+ subsidiaries. It applies to all employees, contractors, vendors, and automated systems operating within the Aevum Zenth ecosystem.
The primary objectives are to:
- Ensure compliance with global data protection regulations (GDPR, CCPA, HIPAA, SOX, sector-specific mandates)
- Minimize legal, financial, and reputational risk through systematic data lifecycle management
- Optimize storage costs and infrastructure efficiency across multidivisional operations
- Maintain data integrity, availability, and traceability for operational and audit purposes
2. Data Classification Framework
All data processed by Aevum Zenth must be classified upon creation or ingestion. Retention periods are directly tied to classification levels and data types.
- Public: Marketing materials, press releases, published research
- Internal: Operational metrics, internal communications, process documentation
- Confidential: Financial records, HR personnel files, vendor contracts, IP
- Restricted: PII/PHI, payment data, encryption keys, regulatory filings
Note: Subsidiaries operating in regulated sectors (Healthcare, Finance, Aerospace) must apply sector-specific overlays to this base classification framework. Deviations require written approval from the Global Data Governance Board.
3. Standard Retention Schedule
The following schedule defines minimum retention periods. Data may be retained longer where legally required, but must not exceed the maximum without formal justification and executive approval.
| Data Category | Retention Period | Disposal Method |
|---|---|---|
| Financial & Tax Records | 7 Years | Secure cryptographic erasure / Certified shredding |
| Employment & HR Files | 6 Years post-termination | Automated purge + audit trail verification |
| Customer PII & Contracts | 3–5 Years (jurisdiction-dependent) | Irreversible anonymization or secure deletion | r>
| Email & Internal Communications | 2 Years | Policy-based auto-expiry + litigation hold override |
| R&D & Intellectual Property | Indefinite | Cold storage archival with periodic integrity checks |
| System Logs & Security Events | 1 Year | Automated rotation + compliant overwrite |
| Marketing & Campaign Analytics | 18 Months | Bulk deletion after aggregation |
4. Storage & Security Standards
All retained data must reside within Aevum Zenth-approved infrastructure. Unapproved cloud providers, personal devices, and unencrypted local storage are strictly prohibited.
Encryption & Access Controls
- Data at rest: AES-256 or equivalent enterprise-grade encryption
- Data in transit: TLS 1.3+ with mutual authentication for cross-divisional transfers
- Access: Role-based (RBAC) + attribute-based (ABAC) controls with mandatory MFA for Restricted/Confidential classes
Backup & Redundancy
Critical operational and regulated data must follow the 3-2-1 backup rule (3 copies, 2 media types, 1 offsite/air-gapped). Backup retention mirrors primary data retention schedules unless otherwise mandated by disaster recovery protocols.
5. Review, Disposal & Archival
Data retention is not static. The following lifecycle procedures ensure compliance and operational hygiene:
- Automated Expiry: All digital repositories must enforce retention tags that trigger automated review or deletion at deadline.
- Manual Review: Business unit data owners must certify data status 90 days prior to expiry. Extensions require documented justification.
- Secure Disposal: Digital media must undergo NIST 800-88 compliant sanitization. Physical media requires certified destruction with chain-of-custody documentation.
- Archival: Historical, regulatory, or culturally significant data may be migrated to cold storage. Archival data remains subject to access controls and periodic integrity validation.
Warning: Failure to execute scheduled disposal constitutes a policy violation. Automated disposal may not be bypassed without explicit written authorization from the Chief Compliance Officer.
6. Legal Holds & Regulatory Exceptions
Standard retention periods are immediately suspended when a legal hold is issued. Holds apply to all data custodians, systems, and third-party processors within scope.
- Legal holds are initiated by the General Counsel or Compliance Division upon litigation, investigation, or regulatory inquiry.
- Hold notifications must be distributed within 24 hours and acknowledged by data custodians.
- Retrieved data must be preserved in original format with immutable audit trails.
- Holds are formally released only upon written instruction from authorized legal counsel.
7. Accountability & Enforcement
Data retention compliance is monitored through quarterly audits, automated policy enforcement tools, and divisional data steward reviews. Violations are escalated based on severity and impact:
- Minor/Procedural: Remediation training, documentation correction
- Material/Non-Compliant: Formal warning, mandatory system access restriction, incident report
- Severe/Wilful: Disciplinary action up to termination, regulatory reporting, legal referral
Policy questions, exemption requests, or incident reports should be directed to the Data Governance Office.
