This breach is a monumental failure of cybersecurity, which raises many pressing privacy concerns. However, beyond those issues, it also illustrates a fundamental problem of the data economy as a whole: databanks like Equifax are too big.

Consumer credit agencies like Equifax are part of the multi-billion dollar data broker industry, which is based on collecting, analyzing, and selling thousands of data points about individual people. They paint a detailed picture of a person’s life and that profile is used to make decisions with direct impacts on, as I have written elsewhere, “many facets of our lives, from obtaining a loan to finding a job to renting a home.” As a company adds to its hoard of data, the value grows exponentially; so, the imperative for data brokers is to continuously accumulate as much data as possible.

As epic as Equifax’s hack was, things can get a lot worse. The credit reporting agencies Experian and TransUnion are data giants on par with Equifax and there are thousands of other data brokers that also possess large databanks. Data breaches like this one are not bugs, but rather features of a system that centralizes immense amounts of valuable personal data in one place.

The vaults of these databanks are impossible to secure, in large part, because the wealth of information they hold is a beacon for hackers. Even the most impenetrable cybersecurity will eventually fail under the pressure of dogged hackers probing for weaknesses to exploit. Better cybersecurity is important, but it is not a solution. It only postpones catastrophic failure.
