With respect to guidance, Okta said that in the fiscal third quarter it's expecting a loss of 12 cents to 11 cents per share, excluding certain items, on $96 million to $97 million in revenue. That's ahead of the estimates from analysts polled by Thomson Reuters, which called for a loss of 17 cents per share, excluding certain items, on $89 million in revenue.

For its entire 2019 fiscal year Okta is calling for a loss of 48 to 46 cents per share, excluding certain items, on $372 million to $375 million in revenue. That's also ahead of expectations from analysts polled by Thomson Reuters, which were a loss of 56 percents per share, excluding certain items, on $356.5 million in revenue.

Also on Thursday, Okta said it has new or larger relationships at 21st Century Fox, Cisco, Pret A Manger and the state of Georgia.

On Thursday's conference call with analysts, Gray Powell of Deutsche Bank asked about the potential impact of Cisco's 2.35 billion acquisition of one Okta competitor, Duo Security.

"I think that partnering with Cisco more broadly and Duo as part of Cisco is going to be great, and we're very optimistic about that," Okta CEO Todd McKinnon said. McKinnon said that Duo is a "really good partner" of Okta's.

Okta stock is up 134 percent since the beginning of the year. In the quarter Okta announced the acquisition of security company ScaleFT. Okta went public in April 2017.
