Ensure data quality

Request A Demo


Crux Protect takes the core Crux Deliver service to the next level by offering users the ability to define and create data quality checks to their specification.

Crux users can now create data pipeline validations, to confirm the data meets their specifications, and anomaly detections, to identify data outliers.

Key Benefits of Crux Protect

  • Guarantee your data conforms to supplier specifications

  • Identify anomalies utilizing a proprietary machine learning model

  • Define custom data quality checks to evaluate proprietary metrics and thresholds

  • Receive data quality calculations for all datasets in a single, machine readable format available via Crux Query or any Crux Deliver destination

How Crux Protect Works

Crux Protect runs data quality checks consisting of two components: a metric (the item to be measured) and an upper and/ or lower threshold.


Metrics are available for many key data quality dimensions. Each can be further modified by using select operators (e.g. and/or logic) and modifiers (e.g. grouping or filters) to create the desired data quality check.

Metrics are available in the following categories: Missing and Duplicate values, Semantic meaning and formatting, and Numeric calculations, both statistical and arithmetic. Custom metrics can also be defined to assess bespoke quality points or business specific rules (e.g. detecting anomalies on an internal time-series factor or validating unstructured text doesn’t contain HTML).


For each check, boundaries are set to determine whether a check passes or fails. Currently, thresholds are either static or relative, based on a historical value of a metric.

Anomaly Detection can be used to calculate thresholds automatically, based on a proprietary model which dynamically adapts to account for changes in a metric’s behavior.

Results and Notifications

Output from Crux Protect is made available as a new dataset which can be made available to clients via Crux Deliver or Crux Query. Notifications are generated in the respective location when data quality results are available.

Unified Data Engineering Approach

Crux Protect is a key component of Crux’s data ecosystem, which includes 24/7 monitoring, change management, and secure access. Your customized datasets can be made available through a multitude of delivery destinations via Crux Deliver, including cloud platforms and API, or you can have Crux host the storage for you via Crux Query.

“We’ve been using Crux for almost two years now and are happy with the company’s ability to meet our high standards.
