RSA and Cisco Live: Viral Events | Gestalt IT Rundown: June 22, 2022

June 22, 2022

The last two weeks have been filled with conferences. RSA happened June 6-9 and Cisco Live was June 12-16. There were also gatherings for Splunk, Juniper, and others around the same time in San Francisco and Las Vegas. While the general mood of the conferences seemed to be focused on how good it was to get people back in person the reality of what that looks like a world still affected by a global pandemic came into focus after everyone started getting back home. RSA, according to reports, has seen reported COVID infections as high as 20% of attendees based on informal polling numbers. CIsco Live, which boasted over 16,000 people in Vegas, is seeing simliar numbers. While I was able to make it through the conference without testing positive many others that I was interacting with didn’t. Which calls into question the practice of having live in-person events during the pandemic. This and more on this week’s Rundown. Head over to gestaltit.com for show notes.
