Online security: your practical starting point
crackthe.net is a practical guide to everyday online security. Every topic here is looked at from one angle: keeping you protected.
Where do you want to start?
Online security sounds complicated. It isn’t, once you know what actually matters. You don’t have to do everything at once – one or two steps already make a real difference.
Only got a quarter of an hour? The 15-minute security check takes you through ten concrete steps you can tick off right away.
Something already happened?
- Emergency help – clear first steps when an account has been taken over or money has gone missing.
Learn to spot the trap
- Spotting scams – how phishing messages, fake invoices and support-call scams actually work.
Lock the front door
- Passwords & 2FA – the single most effective thing most people can do.
Check it yourself
- Free self-checks – find out who is logged into your accounts and whether a link is safe, without installing anything.
Test what you can spot
- Security test: can you spot the danger? – ten real situations, from the delivery text to the support call, with answers and explanations.
- Terms quiz – the ten words that turn up in every security warning. Do you really know them?
Why one angle only
There is no shortage of technology news and gadget advice online. What is much harder to find is calm, practical guidance for people who simply want their accounts, their money and their family to be safe.
So we keep the scope narrow on purpose: no investment tips, no daily news, no general tech tricks. Just security advice that still holds up in a year – and that tells you honestly when the best answer is a free setting rather than a paid product.
What you can rely on
We test independently, write in plain language, and take no money for good ratings. How we work is set out openly in how we test and our editorial standards .
