Outsourcing digital forensics

Hi I posted this a couple of weeks ago on the Services forum but no-one has replied, hence re-trying here.

We currently conduct in-house forensics from time to time, typically involves checking to see if a user had stored any business-related documents on external media and if so when was the last time they accessed them. We also use ShellBags to look for the presence of business-related folders on external media. Basically building a picture.

We might want to out-source this operation in future, I appreciate that 3rd parties wouldn't be able to make any value judgements as what constiutes relevant business documents so would expect a deliverable to state factually what was where and when.

Does anyone know any 3rd parties who could take on this type of work in Connecticut and/or Texas?  Also look for a supplier in UK. We would send the computer together with decryption key (currently McAfee WDE but moving to Bitlocker with Intune) to the 3rd party. .

Also, we don't do currently any forensics on mobile devices (skills and tools), but I can't see that this is not an area we wouldn't want to explore in future so would be good if 3rd parties also had that capability.

Recommendations on vendors would be good, if anyone has a feel for pricing too that would be great!

PM me if that's better for you.

Look forward to hearing from some folks

Peter
