Khurshid said SFIO's investigation was limited to alleged corporate law violations by Satyam founder B Ramalinga Raju, and others.
He further said foreign exchange violations would be probed by the Enforcement Directorate, revenue manipulations would be looked by the Income Tax department and other cases would be investigated by the Central Bureau of Investigation.
Satyam scam came to light early this year when its founder and then chairman Raju revealed manipulations in accounts for several years running into thousands of crores of rupee.
The ministry had devised a system where the government would be able to detect corporate frauds at an early stage, he said.
There will be 15 warning parameters that would be applied to companies which are under scanner, Khurshid said.
Officials will check periodically on revenues, profits and other issues like employees strength. The system will alert if there is any abnormality in records, he said.
The companies, which do not satisfy those parameters, would be questioned and closely monitored to avert future frauds.
