# Is antivirus enough for a small business?

No, not on its own, although it is a necessary start. Antivirus and endpoint protection stop known malware on the computers where they run. They do not cover a stolen password used to log in from outside, an e-mail asking the accountant to pay a fake invoice, a device where no antivirus can run, or an intruder who uses your own administration tools, which antivirus treats as legitimate. A sensible small-business baseline is multi-factor authentication on e-mail and remote access, updates applied quickly, endpoint protection on every computer, backups kept offline or immutable and tested, and a short written plan of who to call. After that, network monitoring shows what antivirus cannot: one device suddenly talking to many others, calling an outside server every few minutes, or sending a lot of data out at night. NetSenX does this on every plan; it does not replace your antivirus.
