Serverless Docs

Welcome to Elastic Serverless

Description

Some users would like to learn about the security and compliance (e.g. specific standards, GDPR) of Serverless. It will be helpful to add documentation in this area in the FAQ or a separate section or cross link from the Serverless documentation to our general security and compliance document.
