Open Source Tamper-Proof Database Adds Immutable Audit Logging and Expands PostgreSQL Compatibility

Major update to immudb provides permanent, tamper-proof records of activity

HOUSTON--(BUSINESS WIRE)--Codenotary, leaders in software supply chain protection, today announced the release of immudb 1.11, a major update to its open source database that adds immutable audit logging and expands PostgreSQL compatibility.

The only immutable enterprise-scale database with cryptographic verification, immudb ensures data cannot be secretly changed or deleted.

“The new immudb focuses on a problem many organizations struggle with: proving that their data – and the actions taken on it – can be trusted,” said Dennis Zimmer, co-founder and chief technology officer, Codenotary, the primary contributor to the immudb project. “While most systems rely on separate logging tools to track changes, those logs can be incomplete, disconnected, or even altered.”

Immudb takes a different approach, storing data in a way that cannot be changed without detection. With version 1.11, this same protection now also applies to database activity – meaning not just the data itself, but also who did what and when can be recorded in a way that cannot be tampered with.

immudb 1.11 introduces built-in audit logging that records database activity directly inside the database itself. Instead of sending logs to external systems, every action becomes part of a permanent, tamper-proof record. This makes it much easier to answer questions like:

• Who accessed or changed this data?
• When did it happen?
• Can we prove it wasn’t modified later?

For organizations, this means:

• Audit trails that cannot be altered after they are created;
• Streamlined compliance and reporting;
• Consolidated logging not a separate setup.

In simple terms, the database doesn’t just store data – it also keeps a trustworthy history of everything that happened to it.

Compatibility with PostgreSQL

In addition, immudb 1.11 is now compatible with PostgreSQL, one of the most widely-used databases, so users continue to use PostgreSQL code unchanged and gain immudb tamper-proof records.

This means many existing applications, tools, and frameworks can connect to immudb without major changes. Teams can keep using familiar workflows while gaining the added benefit of tamper-proof data and audit trails.

These capabilities are especially valuable in areas where trust, accountability, and traceability are critical:

• Financial systems - Transaction records that cannot be altered, plus help with audits, fraud investigations, and regulatory reporting;
• Software development and deployments - Tracking who approved code changes or triggered deployments with records that cannot be rewritten later;
• Cybersecurity and incident response - Ability to reconstruct exactly what happened during a breach using a timeline that attackers cannot manipulate;
• Regulated industries - Simplified compliance in sectors like finance, healthcare, and government by relying on built-in, trustworthy audit trails instead of complex logging setups;
• AI and automation systems - Recording decisions and actions taken by automated systems or AI agents, providing accountability as these systems become more autonomous;
• Supply chain and data tracking - Verifying the history of data, products, or transactions across multiple steps, ensuring nothing was altered along the way.

Immudb is used by many thousands of organizations worldwide to create solutions that require a zero-trust approach to their sensitive data. There have been more than 50 million downloads of immudb.

Immudb 1.11 is open source and available on GitHub at https://github.com/codenotary/immudb.
