A project to roll out 200 PCs to the e-Envoy's office in May has been delayed following concerns about the quality of the security system.
The 'Icom' project, run by Cap Gemini Ernst & Young (CGEY), won't be complete until the end of the year after the e-Envoy's office decided that CGEY could not deliver.
The delay is an embarrassment to the office, which has responsibilities for e-government and ecommerce.
A spokesman for the e-Envoy said: "Because of our strong internal management processes we were able to spot that CGEY was not in a position to deliver.
"The system has never been rolled out and no users have been affected. We only pay when we get the product."
And he confirmed that "security was one of the problems".
IBM was called in to check the decision. "IBM agreed with us and has told CGEY to make further refinements to the programme," said the spokesman.
At the moment only some staff can access government systems remotely. Part of the aim of the project was to enable civil servants to access systems securely from other countries.
CGEY failed to reply to requests for comment by the time of going to press.
