Companies with between 50 and 249 employees are at an above average risk of fraud, according to research by law firm, Foot Anstey. The survey of 1,000 senior managers across the UK revealed that 53% of medium businesses have had to act on fraud in the last year against a national average of 45%, and while the risk for businesses with less than 50 employees is lower, it is still significant with one in five having been affected.
