Owned by the St George Bank, Asgard has about A$33 billion (US$25.4 billion) in funds under management with 700 staff around the country.

Asgard systems and security manager Patrice Li advocates keeping a close eye on the market to ensure the relevancy of existing security systems.

As an example of rapid change, Li cited a spate of virus attacks two years ago which have since given way to phishing and other money-grabbing scams.

With its head office in Perth, Asgard has focused on consolidating core services back to its main data center which has had to cope with a sharp rise in data.

"When I started four years ago, the company was managing A$18 billion and we bought two high-end Sun storage systems with 2TB each," Li said. "Now we have about 50TB of storage."
