"I couldn't be more excited to join Secureworks at a time of astronomical growth, evidenced by Secureworks Taegis XDR reaching $100M in ARR within the first two years of launch," said Georgiou.
Secureworks, he said, is "uniquely positioned to help organisations find the solution that solves security's toughest challenges, and there's nothing better than knowing our work helps security analysts sleep easier and CISO's focus more time on strategy."
