About Sentra
Sentra provides an AI data security and governance platform. It discovers, classifies, and governs data that AI can access, from Copilot to Bedrock, at petabyte scale. The platform addresses risks such as data sprawl, overpermissioning, and ungoverned data. It sells to organisations that use AI and need to protect sensitive data. The company serves sectors including retail and healthcare. Its architecture runs scanning inside the customer environment, so no data leaves the customer cloud. This design aims to be more secure and compliant. Sentra also offers Shadow AI DLP to prevent sensitive data from being shared with AI applications. The platform integrates with existing security and IT stacks.
