Figure 1 – WAN Firewall Policy Using the centralized Cato Management Application (CMA), it is simple to create a policy based on a zero-trust approach. For Cato services, the default way to connect a site to the network is with a zero-touch edge SD-WAN device, known as a Cato Socket. See Figure 1 below. allow IOT devices (e.g.

Rather, these firewalls are also used for securing WAN access, datacenter LAN segmentation and ensuring reliability and high availability to network traffic. This enables them to secure traffic directed at datacenter applications and also direct traffic to the right server and applications within the WAN.

NSGs use the source and destination address and/or port methodology which doesnt provide application layer visibility and logic. The outside subnet will be used for the appliances WAN interface, and inside for the LAN. It can also become overly complex to implement and troubleshoot as the environment increases in scale.

This could mean the users are saturating the internet connectivity or that they’ve saturated the LAN (or maybe WAN). This configuration is known as a “split-tunnel” configuration and is set up by rules to exclude specific ports, protocols, or networks. More advanced VPNs can do this by application type.

Both packets and flows provide information about the source and destination IPs, ports, and protocols. Whether it’s tcpdump, Wireshark, or SPAN port, you’ll be able to get needle-in-the-haystack data with packet captures. The old saying about packet captures is that packets don’t lie!

This has necessitated a rethink of the WAN architecture. This has led enterprises to adopt SD-WAN technology, which enables them to eschew bringing all traffic back to a central data center and route traffic directly to branches or the cloud, as needed. For most organizations, the cloud is a critical piece of their transformation.

Until just a few years ago, enterprise networks were predominantly comprised solely of one or more private data centers connected to a series of campuses and branch offices by a private WAN that was based on MPLS VPN technology from a major telecom carrier. But cloud realities break that assumption.
