The ban order by Chief Minister V Narayanasamy is in contrast to Bedi's push for the use of social media for monitoring implementation of government schemes.
She has recently created a WhatsApp group for exchange of information and details of implementation of various schemes by the government departments. An Officer on Special Duty in the Raj Nivas is the administrator for the group.
It said the server of these multinational companies were based outside the country.
"Any foreign country can get access to these official communications and documents uploaded which is a violation of Official Secrets Act (OSA) and also against the guidelines issued by the Union Information and Technology Ministry," it said.

The circular also said that the Chief Minister instructed that no group should be formed for official communication and the officers should not be members of any official group run in such social media.
The circular said wherever it was essential and unavoidable, written permission should be taken from the Chief Secretary for taking up government work through social media.
Bedi had on December 31 suspended Registrar of Cooperative Societies A S Sivakumar after he allegedly posted an "obscene video clip" in the WhatsApp group of officials of which the Officer on Special duty in Raj Nivas is the 'admin'.
Subsequently, on a complaint from the OSD, a case under Information Technology Act had been registered against the PCS officer.
"The Lt Governor should follow the statutory procedures and also create an environment to ensure that the purpose of having an elected government was fulfilled," he said.
Asked if as PCC president he would urge the Centre to recall Bedi, he said that "I do not make such demands".
However, he said he would "insist that the Lt Governor function in such a manner that the people's expectations are fulfilled through the elected ministry and she alsoshould extend her cooperation to the elected ministry".
Chief Minister V Narayanasamy had held a meeting of officers including PCS officers some time back to express his displeasure over the use of social media for official communication.However, he did not come out with open comments against the Lt Governor.
Even in the wake of suspension of the PCS officer, he told reporters that he did not want to be drawn "into any administrative matters."
He has, however, been maintaining that there was clear demarcation of powers and subjects between the Lt Governor and the council of ministers .
"Such demarcation is seen in the constitution of India, the Government of Union Territories Act 1963 and the Conduct of Business Rules," he has said.
Welfare minister M Kandasamy for instance pointed out recently that the Lt Governorshould function in tandem with the elected ministry.
The AIADMK legislature party leader A Anbalagan said yesterday that "frequent tussle between the Lt Governor and ministry is however causing administrative paralysis and the Union Home Ministry should intervene and find a solution including keeping the ministry in suspended animation to bring the agonising situation to an end."
The BJP's Puducherry unit leader V Saminathan had also yesterday opposed the comments against the Lt Governor by the Congress.
