Differences between firewall and antivirus

 Since we're talking about antivirus, let's understand the differences between it and the firewall. Although both are intended to protect the machine from threats, the firewall is not an antivirus . The two tools operate in different ways and the implementation of one does not exempt the installation of another.


The firewall operates as a data filter, which authorizes or blocks the entry and exit of information through the configured gateways. However, the input ports of the browser or in the e-mail software are automatically released.


In other words: the firewall is unable to block the content received through e-mails, websites and other tools.

The Field Service Technician professionals will be accountable for upgrading the equipment including applicable software, hardware, and data telecommunications network equipment.  

This means that, even with the firewall properly installed and configured, the machine is not completely protected from spam messages, malicious links and suspicious files.


Therefore, it is necessary to install an antivirus, which will protect the computer from such threats.
