I have seen a lot of posts from those who are new to IT and need help planning their certification paths...however I have the opposite problem. I have been in IT for 13 years but am only now starting to gather certifications. My work experience is general in nature, with lots of tech support and Network administration type titles. My knowledge is spread around among many different aspects of IT in Windows environments. I have my Network+ certification and am now studying for Security+, but not sure where to go from there. Assuming it is too late to specialize, what verifications would make me most valuable and well rounded? I'm thinking about Linux Certifications, MSCA, Virtualization or ones having to do with higher levels of Networking and/or IT Security but every time I try to research them I get to running in circles. Anyone have some advice?
