IT guides for businesses
Short, practical answers to the questions businesses ask us: Wi-Fi, backups, security, who should run your IT.
Weak office Wi-Fi: the causes and the right fix
Weak office Wi-Fi almost always comes from a single router in a corner, wireless repeaters, and too many devices on one network. The lasting fix: 2–4 access points wired back with cable and placed after a survey, with separate networks for staff, guests and cameras.
The 3-2-1 backup rule for small businesses, explained simply
The 3-2-1 rule means: 3 copies of your data, on 2 different kinds of storage, with 1 of them somewhere else. Against ransomware, add a copy that cannot be altered and regular test restores: an untested backup is not a backup.
In-house or managed IT: what suits a small business
For a company with fewer than 30–50 staff, managed IT usually costs less than an employee and covers more specialities: network, security, backup, support. An in-house IT person makes sense when there is daily work for them or very specific systems. The riskiest option is "a friend who knows computers".
Does NIS2 apply to my company? How to check and what to do
A company generally falls under NIS2 if it operates in one of the sectors listed in the directive's annexes (for example energy, transport, health, water, digital infrastructure, manufacturing, food, courier services, waste) and has at least 50 staff or more than €10 million in turnover and balance sheet. Some entities are covered regardless of size. Covered companies must register with DNSC, apply security measures and report incidents within 24 and 72 hours.
