Long Live UNIXKey reasons to choose OpenServer 6 over

Linux

15

OpenServer 6 Costs Less

SCO = SCO OpenServer 6: Priced from

$599 to $1399.Customers pay once for the product and run it for as long as they like.

Linux = The Linux “bait and switch”

Linux distributors charge customers from $349 to $2,499 every single year.

Over five years, that same customer pays from $1,745 to $12,495.

16

SCO Has a Superior Kernel

SCO =OpenServer 6 includes:

UNIX System V Release 5 (SVR5) kernel

The result of more than 25 years

of high-end development work Proven track record of stability

and reliability.

Linux = Linux is still young from an

operating system perspective. Less stable More vulnerable

17

OpenServer Has Better Security

SCO = SCO UNIX platforms had the

lowest number of vulnerabilities of any operating system they had studied. SCO OpenServer 6 has all the latest security protocols and encryption systems.

Linux = Linux had the greatest

number of security vulnerabilities with 65.64%

Linux = Loosely organized set of

volunteers and vendors Disparate directions

SCO OpenServer and Xenix.
