Recommendation for Digital Forensic Provider

Dear all,

I'm now in the midst of gathering a list of potential IT/Digital Forensic
providers that could be engaged by the company that I work for if need be.

Do you have any good and trustworthy IT/Forensic provider or professional that you have had experience working with that you could recommend? Location/country doesn't really matter as we are a multi national company and we might need such service there one day.

Please PM me if you prefer to recommend privately )

Thank you very much for you help!

regards,
-eng
