7 experts to follow to boost your cybersecurity career

28 Jul 2023

If you work in cybersecurity and want to stay up to date with the trends and challenges, make sure you’re following these industry experts.

A key piece of career advice, no matter what industry you’re in, is to network, get to know the main players and leaders in the sector and stay on top of the latest industry trends.

To help you do this in the cybersecurity world, we’ve taken a closer look at just seven experts in the field whose work you would do well to follow.

It’s worth noting that, before his passing, legendary white hat hacker Kevin Mitnick would have been on this list.

Mitnick rose to fame when he was arrested in 1995 for multiple offences, including breaking into the networks of major firms such as Nokia, Motorola and IBM. His interest in hacking began thanks to his curious, mischievous nature and a love of both magic and pranking.

It is still worth reading up on his life and work, including an interview he did with SiliconRepublic.com in 2018, before diving into the rest of our list.

In an interview with SiliconRepublic.com in 2021, she said the threat landscape is evolving at a dangerous pace. “The other part of the problem is that cybercriminals are just getting better at what they do.”
