The "AI" Security Insights Show Episode 288 - The Recap Edition. OOOO...Anthropic made a BooBoo! We got to meet the security legends, Clive Watson and Craig Fretwell!

Let’s talk Sentinel, AI Security or lack thereof and we think Agent365 is pretty cool when mixed with Microsoft Purview.

Words of Wisdom:

“Anything you say before the word “but” does not count!

“Ask anyone that you admire: Their lucky breaks happened on a detour from their main goal. So embrace detours. Life is NOT a straight line for anyone.”
