CHECK certified?

I've seen a couple of ads for jobs in the U.K. that ask for someone who is "CHECK certified." Can anyone fill me in what that means? It doesn't seem to refer to Checkpoint certification (e.g., on the FW-1 firewall). I've tried to stay on top of all the security certifications available out there, but I've never heard of this one before.

Thx,
Mike Smith
