Custom Solutions, previously known as Avanteos, is a full-service wrap with a range of investment options, tax reporting systems and risk insurance solutions for superannuation.
The agreement would allow Guardian advisers to offer a more comprehensive product to their clients, Guardian executive manager Steve Browning said.
"This white label will be the lead offer for Guardian advisers wanting to provide a full-service platform to their clients, incorporating a comprehensive retail risk solution using Asteron's award-winning Lifeguard product," Browning said.
"It will also form the cornerstone for Guardian advisers as they transition to a fee-for-service-based client value proposition."
Guardian has 145 financial advisers with $1.4 billion in funds under advice and $100 million of in-force life risk premiums.
CFS said Guardian was expected to be the first of a number of new white label agreements this year for CFS Custom Solutions, with discussions currently taking place with other advisory groups.
Separately, CFS has expanded its FirstChoice platform with the addition of new investment options, including Aspect Diversified Futures, Colonial First State Emerging Markets Select and Platinum Asia Fund.
