Why email is the first thing attackers go for

If a hacker takes control of your email, they can usually get into other systems too, because most “forgotten password” links are sent to your inbox. A single hidden forwarding rule is enough for them to watch your invoices, wait for the right moment and redirect a payment. Cloud email is not secure by default, and even the best filters cannot catch everything.

  • 90%+of successful attacks involve human error
  • 40%of UK businesses enforce MFA everywhere
  • 60%+of people reuse passwords across work and personal accounts (NCSC)
