"The current business environment is challenging across the globe. Rohan brings deep IT and security expertise to the role and has a history of creating strategic customer and partner relationships," said Forescout APJ regional vice president Wahab Yusoff.
"He will build on a strong sales force with long-term customer engagements in the region and provide support across ANZ as we continue to grow and invest in the region."
Langdon joins Forescout from McAfee, where he worked most recently as ANZ regional sales director.
He previously held sales management roles at Salesforce and Intel Security (now McAfee), and earlier in his career worked in sales at EMC and Aconex.
"Businesses across the world are facing major challenges as they navigate new protocols and implement working from home technology," said Langdon.
"Security is a critical component of ensuring business resilience during this period and ensuring vigilance with device visibility and control is a key component. I look forward to collaborating with our customers and partners to help them navigate and improve their security posture and prepare for what lies ahead."
