Computer / Mobile Phone Data Forensics

In today’s fast moving world, computers and mobile phones are used daily in the business world and even students. Commercial Investigations (CPIS) LLP has developed a specialised team to recover deleted evidence from computers and mobile phones.

Whether it is pertaining to commercial related matters or infidelity issues, one may `delete’ or `reformat’ his computer. You may ask an IT guy to check the computer hoping to recover some evidence. He may check the computer and declare that much of the information you require is already not available. Our specialised team will attempt to recover the following:

  • Deleted files
  • Deleted emails
  • Deleted pictures/video clips
  • Websites visited
  • Files downloaded
  • Unallocated files


Case 1
