Before you choose
Match the platform to your environment
Check whether a tool runs on the web, Windows, Linux or macOS, or through a self-hosted deployment. File analysis can also link to another service through an API.
Choose a deployment model
Look at web, self-hosted and on-premise deployment choices. Your security, network and administration requirements should guide the deployment choice.
Check the analysis work
Review the fields for sensitive-data scanning, file classification and duplicate detection. These functions address different parts of file review.
Review remediation and API access
If the workflow needs action after discovery, check the available remediation actions. Confirm API access when another system must receive findings or start a task.
