# About Cognite Data Fusion (CDF)
With Cognite Data Fusion (CDF), you can store, contextualize, and analyze all your technical data in the cloud and ensure that you manage and use your information and insights efficiently.
Cognite Data Fusion provides data integration tools that help you extract, import, transform, and contextualize data from siloed source systems. We also offer data governance tools to manage and view the data that you have integrated into Cognite Data Fusion. And with our access management tools you can make sure that the right people have access to the right data.
You can interact with your data through the CDF portal application or you can work with the data with our API and SDKs.
