10 Cybersecurity Influencers to Follow – and Learn a Thing or Two From!

Posted by: Menachem Shafran

The world of cybersecurity changes more frequently than most of us change our socks – and definitely more often than any of us change our passwords. One minute, state-sponsored attackers are compromising federal agency networks via Log4j and the next, hackers are using Google ads to distribute ransomware. If you’re not news-obsessed – and have an actual job to do – you may just miss something.

Thankfully, there are loads (truly loads) of cybersecurity influencers out there who’s blogs, social media accounts, and podcasts filter the stuff you actually need to know about from the stuff you can safely skip so you can get back to work (or, more likely, get back to catching up with season 4 of Manifest). Some of these experts go deep into the inner workings of exploits and events, while others provide a more topical perspective. Whatever your preferred style, there’s probably something you can learn from each of them. 

So in no particular order, here is our round up of cybersecurity influencers to follow, as crowdsourced by our in-house experts. Note that as of late, some security professionals have intimated they may have plans to move away from their Twitter accounts to federated platforms like Mastodon due to “company restructuring” but for now, most of them have remained and have promised to update their followers if they do indeed move.
