Security tips
Small steps. Big difference.
Wi24rd’s IT security tips: concrete setups you can finish in an afternoon – written by someone who has worked in IT security for about 20 years.
The tips
Start with what attackers see first.
Each tip closes a gap attackers look for automatically. Take them in whatever order suits you.
How the tips are written
- Each tip can be set up in under an hour – without being an IT specialist.
- No advertising and no affiliate links. Wi24rd gets nothing for recommending a product.
- Every tip is re-checked, and the date is on the page. Prices and buttons change – so they are checked again.
