Sybase, too, however ours is a system designed to meet National
Computer Security Center (NCSC) B2 security assurance and features
criteria (meaning it would be suitable for handling fairly highly
classified data for multiple users at different security clearances.)

It is still in development.  I gave a paper, called "A Trusted Database
Machine Kernel for Nonproprietary Hardware," on it at the 12th NCSC
conference in October.  A basic difference between our approach and
those of BLI and Teradata is that our system is targeted toward the VAX
line, and conceivably to other architectures.  Although VAX is made
only by a single vendor, hence could be called "proprietary", it's got
a much greater installed base than BLI or Tera., and DEC does not own
this software.
