Here's how to tell if yours is one, and how to take it offline for good. Somewhere in your plant or remote infrastructure, a controller might be reachable from the public internet right now. Someone probably set up remote access years ago so they wouldn't have to drive an hour out to a remote site every time it needed a look. Nobody circled back. For a long time, that felt harmless. Last month, it stopped feeling that way.

Industrial automation is changing fast, but some of the biggest challenges remain surprisingly familiar: connecting equipment, getting useful data where it needs to go, and building systems that don’t box you in later. Edge solutions are increasingly helping solve those challenges in both greenfield and brownfield systems. But don't you want to see what that actually looks like in practice? Listen in as Opto 22's Dan White sits down with the Inductive Automation *Ignited* podcast team to break down four simple edge application stories that led to huge results.

Do you work in a very specialized industry where downtime means major profit loss and technicians are hard to find?  That was the problem facing CryoPhit USA, an OEM manufacturer of cryotherapy chambers. These systems produce extreme temperatures, and fixing them can be time consuming. If a machine goes down, the operator's revenue stops cold. In episode 8 of the *Who’s groovin* video series, see how CryoPhit turned a hard-to-service refrigeration system into one they can diagnose remotely and predict failures for before they happen.
