Here's ISC's Petr Špaček giving his "Brace for Upgrades" talk at #RIPE92 last week, as well as a slide from his presentation. The bottom line: streamline your deployment processes, because you're going to need to update often to keep up with the onslaught of AI-discovered vulnerabilities.

Enjoy a couple of pictures of Ondřej Surý speaking at #RIPE92 ! Were you there for his talk? What did you think?
