Auditable Change Management release

Codenotary announces the release of a new product: Auditable Change Management (ACM).

Do you observe that your company pays for licensed software much more than it could? Now with ACM you are able to cryptographically prove that you never exceeded the agreed amount of resources and software instances.

ESXi Changes

Track all changes – ESXi host or virtual machine

Never let the new network in your ESXi host slip in unnoticed or let the host move between clusters without control. The ACM detects automatically changes in the ESXi servers (hosts) and logs them into the tamperproof, immutable database. You can search the changes by entering part of the hostname, choosing any time period in the calendar, and filtering the results by type of change.

Types of changes that are tracked:

  • Hosts moving between clusters, added and removed from the cluster
  • Number of CPU Cores, Sockets, and Speed (frequency)
  • Amount of memory
  • Network, the composition of Host Portgroup, and Distributed Virtual Portgroup
  • VM added, deleted and moved between hosts

The above view presents the five last changes. You can drill down to see all the changes in the host in the given time period.

Clicking on an object card presents a detailed view with a summary of the changes and a scrollable list of changes.

With ACM you can track every change using the detailed dashboard view.

Virtual Machine Changes

Keep an eye on what is changing in your infrastructure. Whether it is the CPU usage, memory consumption, or the number of Virtual Machines running licensed software, you will always be able to prove the numbers in an irrefutable way. VM Dashboard presents a similar view of all the changes that occurred to your virtual machines in the selected time. Changes tracked per VM:

  • VM was deleted and a new VM created
  • VM added and removed from the cluster
  • VM added and removed from the host
  • VM cloning (including creation from a template)
  • CPU Cores, Sockets, Number of CPU changes
  • Memory configuration changes
  • VM network configuration changes
Cluster changes

Cluster Dashboard allows to drill down into changes occurring in the cluster. Each of the three dashboards offers a compact view (entity cards aligned two in a row) and an extended view where each card spans across the screen. Changes tracked in clusters:

  • Cluster added or removed
  • CPU Cores and Socket number
  • Memory changes
  • Network (Host Portgroup or distributed vSwitch or Uplinks)
  • VM added/removed from the cluster
Alerts Dashboard

Alert on changes and potential license violation

Harness your environment comfortably by Rules and Alerts. Decide on which rules are important to you and be alerted when crucial aspects of the infrastructure have shifted. The ACM has a set of 20 predefined rules that may be turned on and off on demand. Each rule will generate alerts presented in the Alerts Dashboard. An alert may be followed by an email notification. The report scheduler will also generate PDF reports with triggered alerts.

PDF reports on changes

Audit Reports

Generate audit reports on demand with one click of the button or easily set a schedule and have the reports generated periodically to be always able to answer audit questions about changes in your infrastructure.

The application allows for very easy deployment as an OVA in a vSphere Client. After the installation in a few simple steps, you can set it up to work with one or many vCenters. The process of patching is user-friendly to allow for the rapid development of new features in the future.

Use Case - Tamper-resistant Clinical Trials


Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).


immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance


Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.


While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace


No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data


IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.


immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence


CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.


As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
