Long-time LogRhythm CEO Grolnick out in favour of new blood

SIEM vendor appoints Mark Logan as new chief exec

LogRhythm has appointed Mark Logan as its new CEO, replacing Andy Grolnick.

In its announcement of the news, the security information and event management (SIEM) vendor made no mention of Grolnick or why he was leaving the 16-year-old company he has headed since 2005.

Logan (pictured) comes to LogRhythm from his role as president of data management solutions at vendor Attunity.

He has also served as CEO of WealthEngine, a data-driven consumer analytics business; and Rivermine, a business analytics company.

His appointment seems to be effective immediately as he is billed as CEO on the company's website, though Grolnick's own LinkedIn account still has him listed as chief exec.

He is the latest in a series of executive hires by LogRhythm since it was acquired by Thoma Bravo in July 2018.

The recent shuffle has seen Sue Buck appointed senior vice president of engineering and Barry Capoot installed as chief financial officer.

"Mark has decades of experience successfully building and leading global enterprise software and SaaS companies," said Chip Virnig, a partner at Thoma Bravo.

"That experience, combined with his focus on customer success, solution innovation and company culture, makes him the ideal leader for LogRhythm."

New boss Logan stated: "I am thrilled to step into this role and have the opportunity to work with an organisation that has LogRhythm's impressive track record of innovation and market leadership.

"LogRhythm's customers run some of the most sophisticated and effective enterprise security operations in the world, and the LogRhythm platform is an indispensable part of how they detect, investigate and neutralise advanced threats.

"I look forward to working closely with our customers and business partners to drive our shared success to new levels."
