The Security Benchmark Report captures information on security budgets and total reported employees in the global enterprise. To calculate security budget allocated per employee across security programs in the Banking sector, the security budget was divided by the total number of employees in the enterprise, before finding the average among all responses in this sector. The above average was based on security programs reporting both numbers. The high and low outlier for each dataset was left out in order to present a cleaner comparison. It should be noted that, while this can be used as a comparison among other security programs in your sector, sectors vary widely on a number of factors, including employee size, whether they are consumer facing, etc.
