It is difficult to quantify the cost of a cyber-attack as it can vary greatly depending on the type and severity of the attack. However, a recent study by the Ponemon Institute found that the average cost of a cyber-attack for a small business is £30,000. This figure takes into account direct costs such as hiring a security consultant or IT professional to clean up the damage, as well as indirect costs such as lost productivity and revenue. Given that 60% of small businesses go out of business within six months of a data breach, it is clear that the cost of an attack can be significant.
