Automatically protecting all Lambda functions with runtime protection in Prisma Cloud can be achieved by configuring a serverless auto-protect rule. This feature allows for the automatic application of runtime protection policies to all Lambda functions without the need for manual intervention or embedding defenders in each function. The auto-protect rule ensures that as new Lambda functions are deployed, they are automatically protected based on the predefined security policies, maintaining a consistent security posture across all serverless functions.

This approach leverages the capabilities of Prisma Cloud to integrate seamlessly with serverless architectures, providing a layer of security that is both comprehensive and adaptive to the dynamic nature of serverless computing. By automating the protection process, organizations can ensure that their serverless functions are always covered by the latest security policies, reducing the risk of vulnerabilities and attacks.
