In the past quarter, Trend Micro has boosted its ANZ staff levels by 20 percent.
Trend Micro managing director Dave Patnaik said security threats are up and the company wanted to align its business so it could "serve customers better".
He said the company has hired across the board with staff taking up roles in sales, marketing and in its channel business.
"We have completed our hiring process and in the last three months [of 2008] we made sure we were placed well for 2009. We have new resources to look into new areas of our business and talk to our customers and partners."
Indi Siriniwasa, sales director, F-Secure ANZ, said the prospects for the company's local operations, which has strong dealings with the ISP industry, remain strong.
