Most of my customers have anywhere from 1 to 10 PCs running Win10 Pro, sharing files between PCs, i.e. pretty basic. All have Norton and Malwarebytes installed. Even so, a few get more than their share of viruses.
And a few have asked me to set up a hardware firewall for them, but I have avoided that so far because I don't know what I'm doing. I am under the impression that they are expensive, difficult to configure, and difficult to maintain. But I'm hoping an expert here at e-e can convince me otherwise--and recommend a hardware firewall that is reasonably priced for a small office, and does not require a rocket scientist to know how to set it up and maintain it.
And if they all ARE complex to configure, I'd need suggestions on how to get started, considering that this will be new to me, and the accompanying user manual might assume a good bit of knowledge about firewall setup that I don't yet have. TIA
