• Request Sensitive Data Detection (PUT, POST)

Note - Sensitive Data Detection requires request format of JSON

Outcome Example

Path Discovery (Leaf Creation)

Request Sensitive Data Detection (PUT, POST)

Requirements

• HTTP(S) Request Traffic

• Distributed Cloud Tenant

  • Load Balancer

  • Route
