Another investment wave: HackSurfer, a cybersecurity company based in Glenelg, has raised $3.5 million, led in part by District-based CNF Investments. Only two years old, the company helps others determine which cybersecurity threats are most likely to target their business. (CAP)

QinetiQ quits on U.S.: British defense technology firm QinetiQ has agreed to sell much of its North America division for up to $215 million to American engineering group The SI Organization.
