# Data ingress process

When working with sensitive data it is important to take utmost care with it.
This will help you to ensure that the data integrity is maintained.

```{attention}
Ensure that you check what the expectations of your {ref}`role_data_provider_representative` are around data handling.
```

## Classification

The first stage of bringing input code and data into the Data Safe Haven is to classify them.
Make sure that you have followed the same classification workflow and agreed on the security tier with your {ref}`role_data_provider_representative` and referee (if applicable).

## Loading data into the environment

Once the classification is agreed, make sure that your {ref}`role_data_provider_representative` discusses the best way to bring your inputs into the environment with your {ref}`role_system_manager`.
