CtrlAltCyber Assured is our own independent scheme. It shows key controls were in place when checked. It is not ISO 27001 or Cyber Essentials certification, and no business can be guaranteed safe from attack.

Cyber awareness

Five quick wins for any UK business.

You can do these today, for free. They stop most of the attacks we see hitting small businesses.

01Turn on multi-factor sign-inOn email first, then banking and social media.
02Check before you payChanged bank details? Phone the supplier on a number you already have.
03Update everythingPhones, laptops, routers and card machines.
04Back up and test itKeep one copy offline and try a restore.
05Pause on urgent requestsPressure to act fast, even from the boss, is a scam warning sign. AI can fake voices too.
