PII Vault - PII Storage & Tokenization in Databunker Pro

In today’s data-driven world, protecting personally identifiable information (PII) isn’t just a compliance requirementβ€”it’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.

πŸ” 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

⚠️ Why Use PII Vault Instead of Regular Database Tables?

Traditional Database Approach Problems

-- Traditional approach: PII stored in plain text or basic encryption
CREATE TABLE users (
    id SERIAL PRIMARY KEY,
    email VARCHAR(255),           -- Exposed in logs, backups, queries
    first_name VARCHAR(100),      -- Visible to all database users
    last_name VARCHAR(100),       -- Accessible via SQL injection
    phone VARCHAR(20),            -- Stored in application logs
    ssn VARCHAR(11),              -- High-risk data exposure
    created_at TIMESTAMP
);

Issues with this approach:

  • ❌ Data exposure in logs, backups, and error messages
  • ❌ SQL injection vulnerabilities expose sensitive data
  • ❌ Database admin access reveals all personal information
  • ❌ Compliance complexity requires extensive additional controls
  • ❌ 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):

-- Modern approach: Only tokens stored in application database
CREATE TABLE users (
    id SERIAL PRIMARY KEY,
    user_token UUID              -- Safe to store anywhere
);

Benefits of this approach:

  • βœ… Zero PII exposure in application databases, logs, or backups
  • βœ… Breach protection - attackers only see meaningless tokens
  • βœ… Built-in compliance with privacy regulations
  • βœ… Simplified architecture - no complex encryption management
  • βœ… Audit-ready with comprehensive access logging

βš™οΈ How PII Vault Works

1. Data Ingestion and Tokenization

When sensitive data enters your system, Databunker Pro:

  1. Accepts complete user profiles in JSON format
  2. Extracts searchable fields (email, phone, login, custom) for indexing
  3. Encrypts the entire record using AES-256 encryption
  4. Generates a secure UUID token for the record
  5. Stores encrypted data in the secure vault
  6. Creates hashed search indexes for efficient lookups

2. Secure Storage Architecture
