From their Google profile
Sun Management is a leading security solutions provider in the Mid-Atlantic and Federal Arena. We position ourselves as a mercenary sales force for internet startup companies. The principals, Jim and John Vanderzon, brothers, are both ex-engineers who enjoy the challenge of discovering the start-up company that has created and developed a solutions paradigm shift. The internet, obviously, is still evolving at a rapid pace and, as such, new problems are constantly arising. To truly be on the leading edge of technology, it is critical to be both selective and educated. Sun Management limits product support to no more than 10 technologies at a time.
