Among these, small businesses are the worst hit, according to figures from payment processor Worldpay.
Of those companies whose customer card data was hacked in 2013, 61 per cent are small businesses.
Operators in the electrical, hardware, and automotive industries have had more card data security breaches than any other, followed by pharmaceuticals, cosmetics, and clothing retailers.
This cost, paid out to third parties who undertake forensic investigations into the fraud and make repairs, is the result of a wider problem facing businesses and consumers.
Worldpay’s data shows that the number of credit and debit cards at risk from security breaches in the UK has grown by 1518 per cent since 2012 – from under 200,000 cards to more than 3 million in 2013. At least 6.57 million cards have been put at risk over the past three years.
Worldpay’s managing director Dave Hobday says that card payments and online purchases are becoming the norm as we move towards a cashless society, but with this comes an increasing degree of risk.
‘While most large companies are strengthening their safety measures, there’s been only a marginal improvement amongst small businesses,’ he adds.
‘Fraudsters go after low-hanging fruit. Small businesses are easy prey, so it’s a real worry so many small businesses still don’t see the value in compliance. If we want to see genuine change, it’s important we support small business owners.’
A data breach can be financially crippling with the investigation alone can cost thousands of pounds, not to mention fines and loss of reputation, says Hobday.
‘Knowing the risks and practicing good security will protect you and your customers in the long term – and that has to be a good thing.’
