To share file hashes between your Netskope tenant and Custom File Classification in Cloud Exchange, you need to:
- Configure a trainable file classifier in your Netskope tenant for Custom File Classification to send file hashes for use in Real-time policy.
- While setting up Custom File Classification for file hash sharing, you will get a list of all the classifier names in a dropdown with the classifiers you previously configured in your Netskope tenant.
- When you have file hashes going to your Netskope tenant, you will need to build a policy to leverage this new data source. In this workflow, the file hashes will be used to enhance Netskope Real-time Protection.
