Sun has set up a division dedicated to providing the underlying infrastructure for fostering electronic commerce.
The Network Security Products Group aims to offer customers an "end-to-end" family of Internet security software products. Sun claims it is the first company to set up such a group.
"To deliver security for enterprise systems is to deliver a key business enabler," said Guy Martin, European marketing manager for Sun's security products.
The group's goal is to transform Sun into the number one security software company. Its solutions will span client-server, the Internet, intranet and extranet-based systems.
The group will be responsible for marketing and developing products such as SunScreen EFS (encryption firewall system), SunScreen Skip and Solstice Security Manager.
EFS is a firewall which has built-in encryption and lets companies run their corporate intranets over the Internet as virtual private networks.
Skip is client software which runs on PCs, allowing remote users to log into the corporate intranet securely through a connection from a local ISP. Solstice Security Manager provides user authentication for heterogeneous networks.
According to Martin, the problem with network operating systems is that "each one has a different method of adding users". Solstice Security Manager is a security administration tool that provides centralised security via a gateway across 19 variations of Unix, Windows NT, NetWare and MVS. Martin said Solstice Security Manager was aimed at reducing the cost of network administration.
Sun said that as companies move towards web-based computing and a global Internet infrastructure, they will rely more and more on such systems being secure. It is this emerging market which Sun wants to win over.
Alistair Lamb, northern European marketing manager for Sun's software products, said: "Customers must be absolutely convinced of the security of the technology involved."
