Version One found that 67 per cent of finance and IT figureheads at companies believe that employees can easily tamper with documents within their organisation.
Alarmingly, one in four has seen a document being tampered with by another member of staff, suggesting firms need to be more careful about how easily accessible their documents are.
Greg Ford, Version One's managing director, said that the numbers are too high as they stand.
"The survey results highlight that internal fraud remains a real risk. Although it is encouraging that fewer people appear to be committing and able to commit internal fraud involving business documents, the figures remain alarming," he explained.
It comes after Tony McDowell, the managing director of Encription.co.uk, said earlier this year that small businesses are not addressing cyber security issues.
