Certifications for SOC team

Hi List,

This question is specifically about certifications that may help us as
team members, to demonstrate competency to the global clients who have
assigned us a task to handle the SOC [security information center] for
them. We have been handed over this responsibilities mostly on the
basis of our experience. [ranging from 1 to 9 years]
Some of us already have CEH, but we all are looking for a line of
certs that has a good deal of respected in the industry.
Thanks in advance.
