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.

[First tip: Shodan Monitor](https://wi24rd.com/en/security-tips/shodan-monitor/)[Report a vulnerability](https://wi24rd.com/en/security/)

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.
