A Howard County cyber security firm has raised $3.5 million in equity financing to build out its marketing and sales team. HackSurfer, which was founded in 2012, recently put its first product on the market — a social media-like cyber security product that lets companies know who’s being hacked. HackSurfer gathers data about cyber crimes as they happen and then transforms the data into a model that is built into a cyber crime data warehouse.
