Under the agreement, data breach clients of Beazley outside of the US will have access to CNC's risk specialists to prepare their organisations and manage them in the event of a breach. This will include training from CNC and social media advice.
The deal comes after the companies worked together on mutual clients, and the firms have already begun offering the service to some clients, although these have not been named.
An announcement from CNC notes data from McAfee estimating the annual cost of data breaches to the global economy at more than $400bn (£267bn), and cites an Economist Intelligence Unit report that found more than a third of customers of companies that had suffered a data breach no longer did business with the companies in question as a result of the breach.
As PRWeek has written in recent weeks, it is an issue that PR firms in Asia are increasingly putting on their clients' agenda, and one that has featured heavily in UK news.
Alessandro Lezzi, international technology, media and business services team leader at Beazley, said: "We understand that for many of our policyholders, one of the most damaging aspects of a data breach is the impact it can have on their reputation."
Richard Campbell, managing partner of CNC London, added: "Breach preparedness is now a critical component of corporate risk management and our global team of experts is looking
forward to working together with Beazley and its clients."
