Top 25 Cybersecurity Startups to watch out for in 2021 Cybersecurity business to protect your business


More than 50% of the world’s population is now online. And as online usage has increased, so has cybercrime.

Experts estimate that in 2021 alone, cybercrime may cost the global economy as much as  $6 trillion US.

In July 2020, Klaus Schwab – the executive chairman of the World Economic Forum – said in a speech that “We all know, but still pay insufficient attention, to the frightening scenario of a comprehensive cyber-attack, which would bring to a complete halt to the power supply, transportation, hospital services, our society as a whole. The COVID-19 crisis would be seen in this respect as a small disturbance in comparison to a major cyber-attack”.

Indeed, as recently as December 2020, even the American cybersecurity firm FireEye was hacked. Complex operational (software) tools were stolen – tools that it uses to test government clients’ defences.

In other words – the hackers now have a potent collection of new techniques to draw upon, to use against other businesses, banks, governments or anyone else they choose.

So what can you do to protect yourself, your computer systems and your valuable, sensitive data?

Fortunately, there are many ‘good guys’ out there who are working hard to produce a variety of tailored solutions to the problems of cyber-attacks.

Here are a few more need-to-know facts:
