Seattle-based cybersecurity startup SignalSense just raised $4.5 million, bolstering its efforts to curb a growing security problem facing organizations ranging from Costco to the U.S. government.

The funding was led by by Trilogy Equity Partners, adding on to another $1.3 million the company raised last year from Seattle-based angels, Ignition Partners and Tola Capital.

The idea behind SignalSense is to fundamentally rethink the way IT departments protect themselves with something the company says acts like a DVR for network traffic. SignalSense records the way endpoints interact on the network, then goes back to learn about users and look for anomalies.

“Security is moving beyond pattern matching, to systems where we collect and analyze all of the data moving inside the network,” SignalSense CEO Lynn Kasel said in a press release. “This volume of data is impossible to think through at a human level. Our goal is to multiply the mind of a security professional by using compute capacity that’s driven by artificial intelligence systems.”

SignalSense plans to use the funding to accelerate its technology development, hire more engineers and build a sales team on the East Coast.
