Special Contingency Risk's (SCR) Brandsaver product, first mooted late last year, will be officially launched tomorrow (Friday).
The cover, which is aimed at small to medium enterprises, will be activated when negative publicity causes share price or revenue to drop.
An advisory panel of experts can also be called in the minimise damage.
SCR crisis management advisor Christopher Flint expects Brandsaver to be well received, as brands now account for up to 80% of market capitalisation.
Flint said Brandsaver is unique because it only covers the initial brand disaster, not the aftermath.
“If the insurance world likes it, our competition will see this as something to emulate,” he said.
