Netskope Cloud Firewall

Note

This document guides you to configure the Netskope cloud firewall. The Netskope cloud firewall controls your organizations' outbound non-HTTP(S) traffic. However, if you intend to manage the HTTP(S) traffic (on port 80/443 and non standard ports), you can refer to the Netskope Secure Web Gateway and Netskope Cloud Access Security Broker documentation.

Netskope cloud firewall provides centralized management, visibility, and consistent policies for distributed offices and roaming users. Also, advanced security and access controls without the cost, complexity, and performance limitations of traditional firewall appliances. Netskope also provides integrated cloud hosted firewall capabilities that allow granular control over your organizations' outbound non-HTTP(S) traffic viz., TCP, UDP, and ICMP traffic.

Netskope cloud firewall provides network security on outbound traffic across all ports and protocols for users and offices. Cloud firewall policy controls include 5-tuple (source and destination addresses and ports with protocol), plus user-IDs and group-IDs, fully qualified domains and wildcards as destinations, an application layer gateway for FTP, and firewall event logging.

With Netskope cloud firewall, you can apply an allow / block security policy based on source and destination IP address, destination ports, protocols, and users.

Netskope Cloud Firewall Key Benefits and Capabilities
