Baltimore cybersecurity startup Terbium Labs has raised $6.4 million to scale up its dark web data analysis and recovery technology. The Series A round was led by Boston-based .406 Ventures and brings the company’s total funding to $9.7 million. The money will go toward scaling up its signature software as a service, Matchlight. The service helps companies determine when their data has been stolen and recover it within minutes of it reaching the dark web.
