Avocent Cybex Secure SCKM140PP4-400 4-Port Desktop KVM Review

Avocent Cybex Secure SCKM140PP4-400 4 port desktop KVM PP4.0 certified VGA DVI classified government

The SCKM140PP4-400 is the current, PP4.0-certified successor to the discontinued SCKM140, keeping the same 4-port desktop form factor and audio switching while meeting today's Common Criteria protection profile that many federal contracts now require by name.

Current Certification Where It Counts

Federal procurement increasingly specifies NIAP PP4.0 explicitly, and the SCKM140PP4-400 meets that bar directly, unlike the older SCKM140 it replaces, which was evaluated under the earlier PP3.0 profile.

Same Familiar Footprint

IT staff already trained on Avocent's SCKM140 desktop form factor and cabling will find the PP4.0 model a drop-in physical replacement, easing fleet transitions.

Comparison to Alternatives

It directly replaces the end-of-life Avocent SCKM140 at a lower price even before EOL markdowns, and it competes closely with the Tripp Lite B002-DP1A4-N4, though that unit is DisplayPort-native while the SCKM140PP4-400 covers VGA/DVI legacy displays that many secure facilities still run.
