The first thing to do is to always use a powerful antivirus, which is capable of neutralizing all possible attacks that may want to reach the PC, or laptop. Another recommendation is to have all the content of the devices updated, from the programs, to the operating system.
It is also very important to know that the Wifi network can be an entry channel for viruses, and hacks, so it is necessary not to leave the connection open and encrypt it; in this same sense, it would be necessary to change the password that comes by default on the router, and also cut off this entry route.
In case you telework from a coworking, or a public space like a cafeteria, it is advisable not to use any public wifi, and use a virtual private network to connect to the internet.
They may seem redundant recommendations, but cyber attacks, and computer viruses exist, and can load in a single instant all the work you are doing, for this reason any precaution in this sense is little.
One of the best options for teleworking is Timenet, a system that guarantees cybersecurity because it constantly improves, since its technology allows you to obtain improvements automatically, and at no additional cost.
