You will need the following services and equipment: A high-capacity Internet service. We will assess this based on the number of people who will connect in the office. Often, a 100Mbs business grade NBN service will be more than enough. A UTM firewall router to protect the office network from cyber security threats. A switch to connect the cabled computers and printers to the network. A small wall mounted cabinet or dedicated space for the firewall and switch (this will be where the network cables all meet) Desktop computers so you can connect to the hosted applications. Other office devices such as printers and scanners.
