If you use the Internet, you need a firewall. If you have more than a single device on your network, you need a firewall capable of advanced features.
Historically, an organization could deploy a basic appliance known as a "firewall" to secure a network. The primary capability of the fiewall was to provide basic Network Address Translation (NAT). NAT means that the network addresses (IP Address) of your local computer is different from the "public address" seen on the outside of your firewall. While this provides an essential and necessary component of network security, it is in and of itself, insufficient.
A typical firewall project looks like a pre-installation audit to understand all of the services and user communities operating "behind" this firewall. An analysis of the network traffic needing to pass in and out of the network is conducted and appropriate hardware and software subscription service are selected. The device and services are pre-configured by navitend at our Northern New Jersey offices and then the equipment is delivered and or transported to the respective site(s) for installation. If possible, a plan is put in place to keep internet traffic flowing on a back-up service to minimize impact to users. The new equipment is installed and exhaustively tested. The old equipment is secured and retained for a brief period in the event we need to "switch back" for any unforseen contingencies. The navitend on-call technical team is made aware of the project to anticipate any "after-hours" calls which may arise from the effort. Similarly, the next few business days, the network support team is on the look-out for any lingering connectivity issues that may arise from the change. Once all services are confirmed operational, the old equipment is responsibly and securely recycled.
Firewalls are typically purchased one time, along with a project to schedule the installation of the network. The cost of the firewall and the related installation are commensurate with the complexities of your network and user communities. For example, an assisted living center operating 24/7 with multiple business units and buildings has more complexity than a small office with three employees working 8-5 Monday through Friday. Beyond the purchase and installation fees, modern firewall solutions come with accompanying maintenance and data subscriptions which are vital to their effective deployment.
