PII Vault for Securebefore it leaves your application.

Securelytix Vaultkey helps applications protect personally identifiable information (PII) through data tokenization and secure vaulting. Keep original sensitive data in a controlled vault and use tokenized values across supported AI and non-AI workflows.

Downstream LLM models & third-party APIs process tokens without exposing raw data.

Definition

What Is aPII Vault?

A PII vault is a secure system that stores and protects personally identifiable information, such as names, email addresses, phone numbers, and identification details.

Instead of sharing original personal data across every application or service, organisations can use tokenization to replace sensitive values with tokens and keep the original data in a designated vault.

This helps reduce unnecessary exposure of sensitive information across modern application workflows.

Original PII → token

  • ABCD-1234-EFGHWXYZ-5678-IJKL_stx
  • Ada LovelaceMqrvte Lio_stx

Original values stay in the designated vault layer. Applications work with tokens only.

Why applications need a PII vault

Your sensitive data movesbeyond your database.

Personal data can travel through APIs, AI models, agent tools, logs, analytics systems, and third-party services. Each additional system that processes original PII creates another place where data access and protection need to be considered.

  1. 01Reduce unnecessary sharingLimit how often original sensitive data is copied across systems.
  2. 02Use tokenized valuesSupported workflows run on tokens instead of raw personal data.
  3. 03Centralize original PIIHandle original data in one designated, controlled location.
  4. 04Controlled data accessBuild clearer, more auditable data access processes.

“Protecting personal data starts with understanding where it enters your application and where it goes next.”

How Securelytix Vaultkey works

Protect PII with tokenizationand secure vaulting.

Vaultkey helps applications separate original sensitive data from the systems that process it.

  1. Step 01

    Application receives PII

    Example: email or phone number submitted through your app.

  2. Step 02

    Vaultkey tokenizes the data

    Original value is exchanged for a secure token.

  3. Step 03

    Original value is stored in the vault

    Kept in the designated vault layer, separate from workflows.

  4. Step 04

    Token is used in supported workflows

    AI applications, APIs, and other downstream services.

  5. Step 05

    Authorized data recovery

    Original value is recovered when required.

Vaultkey enables applications to use tokenized data where appropriate and recover original values through supported authorization and detokenization workflows.

Key capabilities

Your sensitive data movespersonal data.

  • PII Tokenization

    Replace sensitive values with tokens for supported application workflows.

  • Controlled Detokenization

    Support authorized recovery of original values when needed.

  • Developer-Friendly APIs

    Integrate tokenization and detokenization into application workflows using supported APIs.

  • Secure Data Vault

    Keep original sensitive data in a designated vault layer.

Use cases

Where can you usea PII vault?

  • AI Applications

    Protect sensitive information in supported AI workflows by tokenizing PII before it is passed to downstream AI systems.

  • APIs and Agent Tools

    Reduce the need to share original PII across supported APIs, microservices, and agent tool workflows.

  • Logs and Analytics

    Use tokenized data in supported logging and analytics flows to help reduce unnecessary exposure of original personal data.

  • RAG and Data Workflows

    Take entire systems out of GDPR, HIPAA, and PCI-DSS scope by keeping raw data out of them.

PII vault vs encryption and masking

How is a PII vaultdifferent?

A PII vault, tokenization, encryption, and masking address different parts of data protection.

ApproachWhat it does
  • PII vaultStores and manages original sensitive data
  • TokenizationReplaces sensitive data with a token
  • EncryptionConverts data into ciphertext
  • MaskingHides part or all of a value

Vaultkey combines tokenization and vaulting to help applications separate original PII from supported downstream workflows. Tokenization does not replace every other security control.

Developer integration

Integrate PIIprotectionwith your application.

Vaultkey provides supported APIs for integrating tokenization and detokenization into application workflows.

  1. 1Identify sensitive data.
  2. 2Send the data to the tokenization API.
  3. 3Use the token in supported workflows.
  4. 4Recover the original value when authorized.

import { Vaultkey } from "@securelytix/sdk"
 
const vaultkey = new Vaultkey({
  projectId: "prod_us_east",
})
 
// 1. Send sensitive data to the tokenization API
const result = await vaultkey.tokenize({
  email: customer.email,
  phone: customer.phone,
})
 
// 2. Use the token downstream in AI models
await ai.chat.completions.create({
  messages: [{ role: "user", content: result.email }],

// 3. Recover the original value when authorized
const original = await vaultkey.detokenize(

Security and data protection

Build more controlleddata workflows.

A PII vault is one part of a broader data protection architecture. Vaultkey can support a more controlled approach to sensitive data handling through tokenization and vaulting, while organisations must still configure and manage appropriate access control, retention, logging, and recovery practices.

  • Protect original data

    Keep originals inside a designated vault.

  • Limit unnecessary exposure

    Reduce where sensitive values appear.

  • Review access and recovery

    Check detokenization permissions regularly.

  • Manage retention

    Configure data retention to your requirements.

DPDP note

Using Vaultkey alone does not make an organisation DPDP compliant. Compliance depends on the organisation's own obligations, processes, and safeguards.
