Why CyberSec?

Cyber-Warfare

Warfare is progressively moving more and more into the digital space.

Whether we like it or not, civilian businesses sustain collateral damage as foreign powers try to take each other down by disrupting assets to the other country.

This might be healthcare, traffic networks, power grid.


Even non-essential companies like accounting firms and SMEs risk:

  • Ransomware attacks which provide funding

I've only added a couple of example links, but the attacks happen so regularly that it's almost commonplace.

Not Yet a Boom

We've seen a crypto boom.
At present, we are in an AI boom.
Cybersecurity has not yet had mass focus.
I want to be ready for when it does.
