The entrepreneur: Gary Kessler, 52, is an associate professor of computer science at Champlain College in Burlington, Vt.
The business: Mr. Kessler has worked as a computer-forensics consultant on the side for the past five years. Computer forensics is the process of gathering evidence from a computer. “Frequently, you are looking at files that someone thinks are deleted,” Mr. Kessler says. “It turns out that when you use a computer almost everything you do leaves traces, and it is next to impossible to delete information from a computer.”
His primary clients are Burlington-area law firms involved in civil litigation, such as cases involving hacking and embezzlement. “But, for better or for worse, most of the cases I have been involved in lately are divorce cases that have turned ugly and [the lawyers] feel there is critical information on the computers,” Mr. Kessler says.
