There are three main pieces: Gateway, Management, and SmartConsole/API.
- Gateways do the enforcement of the Access Policy and Threat Prevention
- Management is where the policy and logs are defined/stored as well as the Internal Certificate Authority (ICA)
- SmartConsole/API is the front end used to create/update the various elements of your access policy
Gateways and Management run on physical appliances or virtual machines that run a purpose-built operating system.
SmartConsole runs on a Windows machine, but you can also use a web browser and/or REST API to manage many functions.
SIC (Secure Internal Communication) secures communication between all components (SmartConsole/API to Management, and Management/Gateway communication).
As gateways are onboarded to management, they are issued a certificate from the ICA, which is used to authenticate and encrypt all communications.
This is done through industry-standard TLS.
