The Ministry of Defence (MoD) has contracted IT group CGI to help it vet 200,000 security clearance applications a year.
The four-year deal will see CGI support most Whitehall departments and major government contractors with vetting staff for security clearances using CGI's NSVS solution.
The tool is based on CGI's old vetting solution, Cerebus, which it has provided to the MoD since 2008, and is built on an Oracle platform.
It will run detailed checks on employees, including financial status, address verification and criminal record checks, which were previously undertaken on separate systems.
CGI and Oracle worked together on the bid to improve the user experience of the software, which is replacing those disparate systems and manual processes.
The new interface allows applicants and case workers to access the system remotely, from different devices, according to CGI.
"With our history of providing vetting services, the transition to this pan-governmental vetting system will be swift, low risk and will ensure business continuity, added CGI's Steve Smart, VP of defence security.
The company said the tool is flexible and scalable, ensuring it can meet increasing security vetting demands set to rise 10 per cent a year.
Vince Groome, CIO of defence business services at the MoD, said: "We are delighted to be working closely together with CGI to make the NSVS application a reliable and robust solution, able to manage the ever changing needs for security vetting.
"As we continue our drive for efficient and customer-focused processes, we are confident NSVS will provide a single solution with a modern, intuitive, scalable and effective approach to managing this critical security process."
