Acorn Growth Companies, a private equity firm investing exclusively in Aerospace & Defense, announced it has acquired CIS Secure Computing, Inc., headquartered in Dulles, Virginia. The acquisition marks Acorn's second in the defense electronics segment.

"CIS has a proven track record and excellent past performance proving that sometimes the best solutions to software weaknesses are hardware solutions. CIS is the undisputed market leader in providing these solutions to the United States Departments of Defense and Energy, and is poised to support America's need for greater network security," said Rick Nagel, Managing Partner for Acorn.
