Survey says security breaches cost companies customers

The Ponemon Institute, which is a good source of such things, has conducted a survey of consumers in the United States which suggests that consumers are willing to show their displeasure over security breaches by ending relations with companies that have compromised their data:

Data Security Breaches Impact Corporate Bottom Lines:

"...'Companies lose customers when a breach occurs. Of the people we surveyed
who received notifications, 19 percent said that they have ended their
relationship with the company after they learned that their personal
information had been compromised due to security breach. A whopping 40
percent say that they are thinking about terminating their relationship,' said
Larry Ponemon, founder and head of the Ponemon Institute.

Even more disconcerting, the survey also reveals that five percent of
Americans have hired lawyers upon learning that their personal information may
have been compromised.

'Five percent may not seem like much, until you realize that anywhere
between 23 million and 50 million Americans have received notification of a
data security breach. That means that over one million people out there are
likely seeking legal counsel,' said David Bender, co-head of White & Case's
privacy practice. 'This should be particularly troubling to companies,
especially in light of several putative class-action lawsuits recently filed
in California against companies that experienced security breaches.'

Bender added that while it's unclear just how any court might calculate
damages for customers whose personal information has been breached, but have
not suffered any clear harm, the fact that the plaintiff's bar is taking on
such suits means they anticipate that courts may commiserate with customers'
frustration over breaches...."
