Tempered Networks has raised another $7 million to help protect companies from cyberattacks with its “identity-defined networking” technology.

Jeff Hussey, the company’s co-founder and CEO who formerly helped start F5 Networks, said the fresh cash will be used for “general corporate purposes.” Investors in the round include Ignition Partners; Ridge Ventures; Rally Capital; and Fluid Capital. Total funding to date in the 3-year-old company is $39 million.

Founded in 2014, Tempered Networks originally focused on IoT security, but today its flagship product is networking infrastructure software that also acts as a layer of security. Its point-and-click “identity-based networking” architecture is based on provable host identities and differs from traditional IP-based technologies.

Tempered Networks sells its technology in industrial sectors such as oil & gas, utilities and manufacturing. The company employs 70 people.

Hussy, who ran F5 Networks as CEO from 1996 to 2002, further explains the technology that powers Tempered Networks’ solution below:
