NCP plans to target users of 64-bit operating systems in the UK, US and Nordic countries who are unable to connect to VPNs using Internet Protocol Security (IPsec).
Users of 64-bit versions of operating systems have so far only been able to connect to VPNs using Secure Sockets Layer (SSL) technology.
"Until now, organisations using IPsec VPNs have had to switch to SSL to allow users with 64-bit systems to connect," said Simon Ford, global sales director at NCP.
The software firm has developed universal software clients for the Windows operating system, including Windows Mobile and Windows7, Symbian and Linux.
"All are universal clients that will enable users to connect to both IPSec and SSL VPNs," said Ford.
NCP made the universal software client available for sale online in the UK in March.
According to Ford, students at Oxford University have been downloading the client to enable them to connect their 64-bit machines to the university's IPsec VPN.
NCP plans to launch the enterprise version at Infosecurity Europe 2009 at Earls Court in London at the end of April.
