    Serverless Defender as a Lambda layer

    Prisma Cloud Serverless Defenders protect serverless functions at runtime. Currently, Prisma Cloud supports AWS Lambda functions.
    Lambda layers are ZIP archives that contain libraries, custom runtimes, or other dependencies. Layers let you add reusable components to your functions, and focus deployment packages on business logic. They are extracted to the /opt directory in the function execution environment. For more information, see the AWS Lambda layers documentation.
    Prisma Cloud delivers Serverless Defender as a Lambda layer. Deploy Serverless Defender to your function by wrapping the handler and setting an environment variable.
    The following runtimes are supported for Serverlerss Defender as a Lambda layer:
    • Node.js 12.x, 14.x
    • Python 3.6, 3.7, 3.8
    • Ruby 2.7
