Mark Logan has been appointed as the company's first-ever CEO.

Logan, a proven leader with nearly two decades of C-suite experience at companies such as Emptoris (now part of IBM) and Attunity (now part of Qlik), comes to One Identity from LogRhythm, where he served as both CEO and board member.

As Attunity president, he played a critical role in increasing the company's stock value by over 200% and its enterprise value by over 330% when it was sold to Thoma Bravo. One Identity says Logan's vision and customer-first approach will enable its continued momentum in capitalising on the market demand for holistic identity security solutions.

"One Identity is uniquely positioned to help companies address the rapid proliferation of identity-based threats targeting their business," Logan says.

"There's a tremendous opportunity for One Identity to be nimble and move quickly to continue accelerating our growth in the identity security market.

"I'm looking forward to working with the leadership team on continuing to win market share as the leading unified identity security provider," Logan adds.

"Logan's deep experience growing enterprise software companies makes him the perfect fit to lead One Identity, the world's top identity security provider," Quest Software CEO Patrick Nichols says.

"One Identity is leading the market as the only company to offer a true unified identity security platform, and I have full confidence that Mark's expertise will help the company continue to capitalise on its market leadership."
