Data security is one of the most important topics we discuss with our clients. A firewall is a great add-on to any network. Not only does the firewall help block network intrusions, it also has many features to manage who has access to data. The firewall allows authorized remote users a secure connection to your network while they are offsite. If you have guests that come onsite and need internet access, the firewall can allow those users to connect to the internet through a public gateway, so they won’t see any of your confidential data.
