The vast majority of security incidents have a human component: a click on a phishing
email, a reused password, a transfer authorised on the back of a CEO-fraud message, or data
shared by mistake. Technology stops a great deal, but not everything — in the end, the
decision to click or not is made by a person.
That is why the human factor is at once the most exploited attack surface and the most
cost-effective to strengthen. No tool replaces a team that recognises a deception attempt
and knows what to do when in doubt: you can invest heavily in technology and still be
vulnerable if people are not prepared. An attacker does not need to break the encryption if
someone opens the door for them.
Good training is not an annual talk that is forgotten within a week. It is turning every
person in the organisation into a first line of defence that spots and reports. The metric
that really matters is not how many people fall for a simulation, but how many report it in
time — and that is only achieved by training continuously, segmented by role and with real
cases, not with a generic video nobody remembers.
