Almost half of Openwork's advisers have moved onto its protection panel since it launched 12 months ago.
Openwork Select features five providers (Aegon Scottish Equitable, Friends Life, Legal & General, Zurich and LV=) which collectively account for almost 40% of the protection market.
The network said users had been writing around 20% more protection business as a result of an increased focus on income protection and critical illness.
Paul Shearman, mortgage, protection and general insurance proposition director at Openwork, added: "For so many users to have adopted the panel demonstrates how important protection has become for clients.
"As advisers increasingly seek to diversify we believe the panel will have an important role to play in ensuring they have the tools they need to meet their clients' protection needs in full."
