How solid is your digital trust—or are you just hoping your PKI is secure?
Let’s be honest: too many companies run on borrowed trust and forgotten certificates. In this episode of Threat Talks, ON2IT’s Lieuwe Jan Koning and Rob Maas pull back the curtain on what really holds your digital world together—and what can tear it down overnight.
They break down PKI in plain language: the root of trust that must stay locked away, the intermediates that keep your systems running, and the automation that stops your team from clicking “ignore” on yet another warning.
You’ll see why rolling your own keys beats trusting anyone else, how to keep your devices speaking the same language of trust, and why short-lived certificates might just save you from the next big breach.
This isn’t theory—it’s how Zero Trust really starts: by proving that your organization can trust itself.
