Hello:
I am shopping for a Computer Forensics Certification. I have 1000+ hours of forensics and investigations experience at a fortune 500 company. I have been looking at NTI, Certified Computer Examiner and Encase certifications. Any tips ?  

IMHO, the EnCE is worthwhile if you will use EnCase and may testify. It is meaningless among practitioners (again, IMO) but is an area where opposing counsel could attack..."So, you use this product, and they offer certification, yet you have not obtained it?" Better to sidestep that than explain it to a lay jury.

The CCE seems useful for similar reasons, you have a general cert in your claimed field of expertise. Meaningless to others who do this work, yet could be of use during direct/cross examination (or to prove to your boss that you are remaining current in the field.)

As far as NTI, I have always used their tools, but didn't know they offered a cert. If it is tool-specific, and you use that tool, it can only help during testimony!
