Sophos was founded in the UK in 1985 and released its first virus scanning engine in 1989.
It expanded its product portfolio, customer base and employee number, opening offices around the world, including Australia, for its Sophos Anti-Virus solutions.
As part of its expansion, Sophos now offers a range of endpoint, email, web, network access control (NAC) and encryption solutions.
"The past 10 years in Australia and New Zealand have been a remarkable chapter for Sophos," said Rob Forsyth, managing director, APAC Sophos.
"Given the exceptional talent of our employees and their commitment to our customers, I am confident that our experience and customer focus will help us drive continued success.
"We have achieved outstanding year-on-year growth and the highest levels of customer satisfaction in the industry."
Paul Ducklin, head of technology, APAC Sophos said the Australian office was the first one to open as a research and development centre.
"Now it is one of the four cornerstone offices in Sophos's global security response operations," he said.
