In today’s data-driven world, protecting personally identifiable information (PII) isn’t just a compliance requirementβit’s a business imperative. Databunker Pro’s PII Vault provides enterprise-grade secure storage and tokenization for sensitive personal data, enabling organizations to build privacy-by-design solutions while maintaining operational efficiency.
When sensitive data enters your system, Databunker instantly encrypts, tokenizes, and stores it in a secure vault. You get back a safe token to store anywhere β even in public databases.
You can run Databunker in the cloud or on-premises, you can enable your enterprise customers to self-host their PII vault in any region, which solves PII export restrictions and reduces compliance risk.
π What is the PII Vault?
The PII Vault is Databunker Pro’s core feature that transforms how organizations handle sensitive personal data. Instead of storing PII directly in your application database, the PII Vault:
- Encrypts and tokenizes entire user records using AES-256 encryption
- Generates secure UUID tokens that can be safely stored anywhere
- Maintains searchable indexes using secure hash-based lookups
- Provides audit trails for every data access and modification
- Enables compliance with GDPR, HIPAA, SOC2, and other privacy regulations
β οΈ Why Use PII Vault Instead of Regular Database Tables?
Traditional Database Approach Problems
|
|
Issues with this approach:
- β Data exposure in logs, backups, and error messages
- β SQL injection vulnerabilities expose sensitive data
- β Database admin access reveals all personal information
- β Compliance complexity requires extensive additional controls
- β Breach impact exposes all stored PII immediately
Databunker Pro PII Vault Solution
Instead of storing PII in your application database, store only the user secure tokens (in UUID format):

Benefits of this approach:
- β Zero PII exposure in application databases, logs, or backups
- β Breach protection - attackers only see meaningless tokens
- β Built-in compliance with privacy regulations
- β Simplified architecture - no complex encryption management
- β Audit-ready with comprehensive access logging
βοΈ How PII Vault Works
1. Data Ingestion and Tokenization
When sensitive data enters your system, Databunker Pro:
- Accepts complete user profiles in JSON format
- Extracts searchable fields (email, phone, login, custom) for indexing
- Encrypts the entire record using AES-256 encryption
- Generates a secure UUID token for the record
- Stores encrypted data in the secure vault
- Creates hashed search indexes for efficient lookups
2. Secure Storage Architecture
