Uploaded: 2026-01-21T13:45:00-05:00
Description: In the first 2026 episode of runZero Hour, Rob King and Tod Beardsley chat it up with fan-favorite OT expert Brianna Cluck from GreyNoise Intelligence.

In the first 2026 episode of runZero Hour, Rob King and Tod Beardsley chat it up with fan-favorite OT expert Brianna Cluck from GreyNoise Intelligence.

They talk about Brianna’s trials, tribulations, and solutions to setting up a home lab for exploring industrial control systems (ICS) gear, using the metaphor of exploring a semi-abandoned summer resort over the winter break.

Rob also has an iron or two in the OT fire (fire is typically undesirable in OT environments, by the way). And as always, Tod and Rob wrap up the past month’s most notable vulnerabilities during the runZero Rapid Response Roundup.
