Runtime Environment

Panther SaaS customers must file a support ticket to have a custom set of libraries or layer applied to their hosted instance of Panther. The following Python libraries are available to be used in Panther in addition to boto3 provided by AWS Lambda:

Package	Version	Description	License
jsonpath-ng	1.5.2	JSONPath Implementation	Apache v2
policyuniverse	1.3.3.20210223	Parse AWS ARNs and Policies	Apache v2
requests	2.23.0	Easy HTTP Requests	Apache v2

For self-hosted instances of Panther, you can add custom libraries by editing the PipLayer below in the panther_config.yml:

PipLayer:
  - jsonpath-ng=1.5.2
  - policyuniverse==1.3.3.20210223
  - requests==2.23.0

Alternatively, you can override the runtime libraries by attaching a custom Lambda layer in the panther_config.yml:

BackendParameterValues:
  PythonLayerVersionArn: 'arn:aws:lambda:us-east-2:123456789012:layer:my-layer:3'
