Following last week's provisional agreement between @EUCouncil and @Europarl_EN on the NIS Directive revision (#NIS2), I'm thrilled to report that it will provide guidance for EU countries to implement a national Coordinated Vulnerability Disclosure (CVD) policy. A thread 🧵👇.

Getting the chance to work alongside many of the people across @Google, @GoogleCloudSec, @Mandiant, @GoogleDeepMind that I considered childhood heroes has been a particular highlight, and it's an incredible opportunity I definitely won't take for granted. I'll miss you all.

What I've valued most, however, are the people. Thank you all for being such fantastic colleagues – for the support, the laughs, the teamwork, and the shared learning experiences.

After five rewarding years here at @Google, I've decided it's time for me to move on. I am incredibly grateful for the opportunities I've been given during my time here. I've learned a great deal, worked on challenging and exciting projects, and truly valued the experience.
