As we close out another year like no other, let's look back at some of the most notable cybersecurity stories that shaped 2021.


Unsurprisingly, 2021 has seen no shortage of notable cybersecurity moments, so much so that it’s no mean feat to whittle the long list down to just a few stories that rocked (not just) the world of cybersecurity in 2021. Nevertheless, which of the countless attacks, vulnerability disclosures and other notable cybersecurity events stood out the most?

Watch the video to learn:

  • how one particular ransomware attack marked a turning point in the US Government’s response to the scourge of cyber-extortion

  • what other scary hack highlighted some of the key threats facing critical infrastructure

  • why US law enforcement accessed hundreds of privately-owned Microsoft Exchange servers

  • which of the year’s many cyberattacks best exemplified the magnitude of the threat posed by supply chain attacks
