In today’s data-driven world, protecting personally identifiable information (PII) isn’t just a compliance requirement—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 — 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.

​
🔐 What is a 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:
  • ✅ Zero PII exposure in application databases, logs, or backups
  • ✅ Breach protection - attackers only see meaningless tokens
  • ✅ Built-in compliance with privacy regulations
  • ✅ Simplified architecture - no complex encryption management
  • ✅ Audit-ready with comprehensive access logging

⚙️ 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

💻 Code Examples: Storing and Retrieving User Records

​
Storing User PII

REST API Example: 
curl -X POST https://your-databunker-pro/v2/UserCreate \
  -H "X-Bunker-Token: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "profile": {
      "email": "[email protected]",
      "first": "John",
      "last": "Doe",
      "phone": "+1-555-123-4567",
      "ssn": "123-45-6789",
      "address": "123 Main St, City, State 12345",
      "dob": "1985-06-15"
    }
  }'
Response: 
{
  "status": "ok",
  "token": "a21fa1d3-5e47-11ef-a729-32e05c6f6c16"
}
JavaScript/Node.js Example: 
const axios = require("axios");

async function storeUserPII(userData) {
  try {
    const response = await axios.post(
      "https://your-databunker-pro/v2/UserCreate",
      {
        profile: {
          email: userData.email,
          first: userData.firstName,
          last: userData.lastName,
          phone: userData.phone,
          ssn: userData.ssn,
          address: userData.address,
          dob: userData.dateOfBirth,
        },
      },
      {
        headers: {
          "X-Bunker-Token": process.env.DATABUNKER_API_KEY,
          "Content-Type": "application/json",
        },
      }
    );

    return response.data.token; // Store this token in your database
  } catch (error) {
    console.error("Error storing user PII:", error);
    throw error;
  }
}

// Usage
const userToken = await storeUserPII({
  email: "[email protected]",
  firstName: "Jane",
  lastName: "Smith",
  phone: "+1-555-987-6543",
  ssn: "987-65-4321",
  address: "456 Oak Ave, City, State 54321",
  dateOfBirth: "1990-03-22",
});
Python Example: 
import requests
import json

def store_user_pii(user_data):
    url = "https://your-databunker-pro/v2/UserCreate"
    headers = {
        "X-Bunker-Token": "YOUR_API_KEY",
        "Content-Type": "application/json"
    }

    payload = {
        "profile": {
            "email": user_data["email"],
            "first": user_data["first_name"],
            "last": user_data["last_name"],
            "phone": user_data["phone"],
            "ssn": user_data["ssn"],
            "address": user_data["address"],
            "dob": user_data["date_of_birth"]
        }
    }

    response = requests.post(url, headers=headers, json=payload)
    response.raise_for_status()

    return response.json()["token"]

# Usage
user_token = store_user_pii({
    "email": "[email protected]",
    "first_name": "Mike",
    "last_name": "Johnson",
    "phone": "+1-555-456-7890",
