SWIPSY was a firewall toolkit produced by the Defence Evaluation and Research Agency in the UK[1] (later QinetiQ).
The SWIPSY toolkit was an ITSEC E3 (equivalent to Common Criteria EAL4) evaluated product[2] that allowed additional code to be added to its security ‘compartments’ without affecting the evaluation status of the toolkit itself.
SWIPSY ran on a Trusted Solaris 8 platform, utilising its Mandatory Access Controls to enforce separation between compartments.
SWIPSY, which stood for SWitch IP SecurelY, was used to build an SNMP firewall system[3] called MIDASS.
[4] SWIPSY technology was licensed by Clearswift for use in its Deep-Secure line of guard products.
