"The producers contacted us, sent us the script, and asked if we could provide any input," said DNSstuff's chief executive, Rich Person.
The company went further: It created Vector Trace, a sleek computer forensics tool that appears in the movie and will soon be available to DNSstuff's customers.
The film, starring Diane Lane, earned over $19 million in its first two weeks. It also provided some welcome publicity for DNSstuff, a five-year-old venture that began as a hobby but which generated revenue of about $1.7 million in 2007, its first year as a money-making business.
