Krishna told CNBC's Sara Eisen on Tuesday that some major deals were put on hold toward the end of the quarter as businesses rethink spending."Mythos is making people pause to say, wait, how much do I need to spend on cyber? They're pausing on new deals until they know," Krishna told Eisen Tuesday. "We don't see our software being disrupted by AI at all."CrowdStrike skyrocketed 12%, while Okta and Netskope surged about 11% each. SailPoint, Zscaler, SentinelOne and Palo Alto Networks each rallied about 7%.
