Databunker is an open-source, Go-based tool for secure personal data tokenization and storage. It can be deployed using Docker Compose or a Kubernetes Helm chart and is designed to help developers protect sensitive data such as PII, PHI, and KYC with minimal effort.

​
The Big Problem with Traditional Database Encryption

Traditional database encryption solutions often provide a false sense of security. While they may encrypt data at rest, they leave critical vulnerabilities:
  • Encryption alone isn’t enough: Most vendors offer disk-block encryption, ignoring API-level encryption
  • Vulnerable GraphQL Queries: Unfiltered queries can expose unencrypted data to attackers
  • SQL Injection Risks: Attackers can retrieve plaintext data through SQL injections
Databunker addresses these gaps with a secure, developer-focused solution for personal data tokenization and storage.

​
Databunker Features

  • Tokenization Engine: Generates UUID tokens for safe data referencing in applications
  • Encrypted Storage: Secures sensitive records with advanced encryption layer
  • Injection Protection: Blocks SQL and GraphQL injection attacks by design
  • Secure Indexing: Uses hash-based indexing for search queries
  • No Plaintext Storage: Ensures all data is encrypted at rest
  • Restricted Bulk Retrieval: Disabled by default to prevent data leaks
  • API-Based Access: Integrates with your backend via a NoSQL-like API
  • Fast Integration: Set up secure data protection in under 10 minutes
