Patch Smarter, Not Harder

Threat Talks - Your Gateway to Cybersecurity Insights

Patch smarter, not harder.
Lieuwe Jan Koning and ON2IT Field CTO Rob Maas break down why “patch everything now” isn’t a strategy, but a risk multiplier. In this session, they teach a practical patching strategy: know your assets, patch edge first, stage updates, and use Zero Trust segmentation to choke off exposure so you only patch what truly matters: fast, safely, and without outages.
