Is a consumer router a security risk for a small office?
It can be: consumer routers often lack regular updates, separate networks and useful logs, and some are left with default passwords. For a small office, check four things. Is the firmware still updated by the manufacturer, and is it current? Is the administrator password changed and remote administration from the internet switched off? Can it run separate networks, so guests, payment devices and office PCs are kept apart? Does it keep logs you can read? If the answer to two or more is no, a small-business router or firewall is a cheap upgrade. Also look for forgotten equipment, such as a 4G router a supplier left in a cabinet.
