I often say that breaches don’t drive companies out of business. Some people are asking me to eat crow because Vasco is closing its subsidiary Diginotar after the subsidiary was severely breached, failed to notify their reliant parties, mislead people when they did, and then allowed perhaps hundreds of thousands of people to fall victim to a man in the middle attack. I think Diginotar was an exception that proves the rule.
Statements about Diginotar going out of business are tautological. They take a single incident, selected because the company is going out of business, and then generalize from that. Unfortunately, Diginotar is the only CA that has gone out of business, and so anyone generalizing from it is starting from a set of businesses that have gone out of business. If you’d like to make a case for taking lessons from Diginotar, you must address why Comodo hasn’t gone belly up after *4* breaches (as counted by Moxie in his BlackHat talk).
It would probably also be helpful to comment on how Diginotar’s revenue rate of 200,000 euros in 2011 might contribute to it’s corporate parent deciding that damage control is the most economical choice, and what lessons other businesses can take.
To be entirely fair, I don’t know that Diginotar’s costs were above 200,000 euros per year, but a quick LinkedIn search shows 31 results, most of whom have not yet updated their profiles.
So take what lessons you want from Diginotar, but please don’t generalize from a set of one.
I’ll suggest that “be profitable” is an excellent generalization from businesses that have been breached and survived.
[Update: @cryptoki pointed me to the acquisition press release, which indicates 45 employees, and “DigiNotar reported revenues of approximately Euro 4.5 million for the year 2009. We do not expect 2010 to be materially different from 2009. DigiNotar’s audited statutory report for 2009 showed an operating loss of approximately Euro 280.000, but an after-tax profit of approximately Euro 380.000.” I don’t know how to reconcile the press statements of January 11th and August 30th.]
