Modern #IT Teams hold their MacBooks in one hand and let #AI do the heavy lifting. #thereIsNoAI #Extreme

Extreme Platform ONE™ Live Demo Series:
Extreme Innovation: Empower IT in the Al Era
Wednesday, May 27
8am PT/11 am ET / 4 pm BST / 6 pm CEST — |
The biggest concern we hear about Al isn't adoption, it's loss of control.
This webinar focuses on how modern IT teams are using Al as a support
system—not a replacement—to make better decisions faster and with
more confidence.
See how the Extreme approach keeps people in charge while Al handles
the heavy lifting—and why this philosophy attracted IT leaders to
Extreme Connect 2026 to learn, test, and validate it in person.
