ntop is a small, engineering-driven company, debt-free with low fixed costs, with many customers, profitable in business for more than 10 years. We develop high-quality networking software used by small individuals as well by large telecom operators, mostly open-source, free for no-profit/research, and provide direct support at reasonable prices. We operate our computers using the green energy (photovoltaics) we produce, our staff is geographically distributed in Europe and North America, we mostly work from our SOHO going to the office only when necessary, this as we see a value in working close to our families and serving remote customers at night when all offices would be closed.
