Seattle-based Tempered Networks has raised an additional $17 million to invest in engineering, sales resources, and partnerships. The company confirmed the new funding to GeekWire this week. The fresh cash brings total funding to $57 million, with backing from Ignition Venture Partners, IDG Ventures, Fluid Capital, Ridge Ventures and Rally Capital. Founded in 2014 by Jeff Hussey, who formerly helped launch F5 Networks, Tempered Networks builds products around the idea of zero trust networking, in which anything that connects to a network must pass an identification test.
