SCOMP got an A1 rating.

Sidewinder uses the priciples developed for LOCK and the MISSI SNS.
Some of SCC's formal assurance people are involved with Sidewinder,
but we do not have the same level of rigor that is applied to the
assurance of SNS.
historical tidbit: SCC is a spinoff of Honeywell's Secure
Computing Technology Center.
