Internet of Things (IoT) security startup Armis, which launched today and raised $17 million, said its product lets enterprises see unmanaged devices in their network.

The company’s agentless IoT security platform integrates with existing IT infrastructure and gives businesses visibility into and management over any device, on or off the corporate network.

This eliminates IoT blind spots, said Armis CEO and co-founder Yevgeny Dibrov.

“More than 40 percent of the devices in the organization cannot be seen by the IT team and security team,” Dibrov said, adding that in the health care sector that figure climbs to 80 percent. “Most are device that you cannot put an agent on: smart TVs, wireless printers, MRIs. You cannot control them in traditional ways and they are very easy to attack and use to compromise the network because their security is weak.”

Samsung Research America, Integrated Device Technology (IDT), and Gett (formerly GetTaxi) are customers. Dibrov said the company has about 50 U.S. deployments and 15 paying customers. “Those 50 focus on health care, financial, and technology, but we’re also starting to see manufacturing more and more.”

Gartner says there are 8.4 billion connected things in use worldwide, and it will reach 20.4 billion by 2020. Cisco puts the number of connected devices at 50 billion.

This ecosystem of everything from smartphones to webcams and keyboards presents a complex security challenge.

Armis CTO and co-founder Nadir Izrael says the company’s software solves this challenge.

“This is our secret sauce: we are able to come into an organization and hook up to the existing network infrastructure, we support all major vendors,” Izrael said. “Within five minutes we hook up to these touch points of the network and show them what’s around their network, what’s in the environment, what’s communicating with what. And we start profiling all of those devices.”

Plus, he said, Armis crowdsources this data from all of its software deployments. “So we’re able to see 200 instances of an IT camera operating and determine which could be constructed as malicious.

“The second part: we can control and police these environments. Visibility is nice — it’s crucial — but giving organizations that ability to control these devices is imperative.”

Armis’ founders are Israeli army veterans turned Silicon Valley tech leaders. They started the company in late 2015. Its headquartered are in Palo Alto, California, and it has an office in Tel Aviv.

Dibrov was on the executive team at Adallom, which was acquired by Microsoft in 2015. He served with Izrael in the selective Unit 8200 of the Israeli Defense Forces, whose alumni also founded Check Point, Waze (acquired by Google) and Wix.

Armis launched with $17 million in funding from Sequoia Capital and Tenaya Capital. Additional investors include Zohar Zisapel, founder and chairman of RAD Technologies; René Bonvanie, CMO of Palo Alto Networks; and Mickey Boodaei, founder of Imperva and Trusteer.

Gartner named Armis a “cool IoT security vendor” in its 2017 report, “Cool New Vendor in IoT Security for Midsize Enterprises.”
