Databunker
A self-hosted, GDPR-compliant Go-based vault for secure tokenization and storage of PII, PHI, PCI, and KYC records.
What is Databunker?
Databunker is a self-hosted, open-source secure vault for tokenizing and storing sensitive personal records like PII, PHI, PCI, and KYC data. It addresses security gaps in traditional database encryption by ensuring data is never stored in plaintext and providing API-level protection against injection attacks. Built in Go, it offers GDPR compliance tools and integrates via a REST API.
Developers and organizations handling sensitive personal data who need a secure, compliant storage solution, such as those in healthcare, finance, or identity management. It is particularly suited for teams requiring GDPR, HIPAA, or PCI DSS compliance with privacy-by-design.
Developers choose Databunker over alternatives because it eliminates the false sense of security from traditional encryption by providing full API-level protection, preventing SQL/GraphQL injection attacks by design. Its self-hosted, open-source nature and built-in compliance tools offer a practical, high-performance vault for tokenization without vendor lock-in.
Overview
Secure Vault for Customer PII/PHI/PCI/KYC Records
Use Cases
Best For
- Securing user profile storage with tokenization to prevent data breaches from SQL injection.
- Building HIPAA-compliant healthcare applications that require encrypted PHI storage and audit trails.
- Implementing GDPR compliance workflows, including data access, portability, and deletion requests.
- Creating a KYC backend for crypto or financial services with secure customer data segregation.
- Managing consent and privacy controls for applications subject to CCPA or other data regulations.
- Storing session data securely with built-in session management and access logging.
Not Ideal For
- Teams requiring complex, ad-hoc SQL joins or real-time analytics on sensitive data
- Organizations without DevOps resources to manage self-hosted database infrastructure
- Projects where bulk data retrieval for reporting or business intelligence is a frequent need
- Startups seeking a fully managed, cloud-native solution with zero operational overhead
Pros & Cons
Pros
Prevents SQL and GraphQL injection attacks by design, as data is accessed only through a controlled REST API, eliminating vulnerabilities in traditional encryption.
Offers GDPR tools like data access, portability, and deletion out-of-the-box, simplifying adherence to privacy regulations without extra development.
Can be set up in under 10 minutes with Docker, using a simple REST API and SDKs, making it quick to deploy for secure data storage.
Generates UUID tokens for safe data referencing, ensuring sensitive information like PII is never stored in plaintext in your application database.
Cons
Requires management of underlying databases like MySQL or PostgreSQL, including backups and scaling, which adds operational complexity.
Credit-card tokenization and enterprise security features are only available in Databunker Pro, restricting the open-source version's capabilities.
Secure, hash-based indexing may not support efficient range queries or complex searches, impacting performance for some use cases.
