Fidelis Security Systems is a network security firm with a focus on extrusion prevention — in essence, stopping leads of data like credit card information, which have plagued large companies of late.
Based in Bethesda, Maryland, Fidelis was founded in 2002. However, this funding is only the second full venture round that the company has taken.
The $22 million investment was led by Tudor Ventures, and new investor Point Judith Capital also participated. Previous investors Inflection Point Ventures, Ascent Venture Partners and the Maryland Venture fund came on as well.
