Background Information
Secure Access - Palo Alto
Cisco has designed Secure Access to protect and provide access to private applications, both on-premise and cloud-based. It also safeguards the connection from the network to the internet. This is achieved through the implementation of multiple security methods and layers, all aimed at preserving the information as they access it via the cloud.
