We believe all IT consulting companies should pursue accreditation, but not for the reasons many usually do — that is, to add letters after their name, a belief certifications mean you've mastered the craft, etc.; consultants should seek certifications as part of the process to ensure they are proficient with fundamental technologies.
At eSG NETWORKS, we are increasingly deploying business solutions that are tested and practical.
CompTIA's Network+, Security+, Server+, CCNA, CCNP, SAP SimpliVity and MCSE certifications are among the best places to start for a consultant who works in heterogeneous environments daily. The network, security, and server fundamentals these accreditations reinforce don't change as rapidly as material tested within, say, a Windows Servers and IT desktop Support certification.
