Armis Inc., a fast-growing player in the “internet of things” security market, today announced that it has landed a $65 million funding round led by Sequoia Capital.

Sequoia had backed a $30 million investment into the startup last year. The venture capital firm was joined by several of the other returning investors that participated in that round, including Tenaya Capital and Bain Capital Ventures.

Armis made the most out of the year that passed between the two investments. The startup claims to have grown revenues by a massive 700% over the past 12 months thanks to strong enterprise demand, with its namesake cybersecurity platform now in use by more than a quarter of the Fortune 100.

Armis enables companies to keep an eye on the connected devices in their networks. The platform maps out all the systems that are linked to an organization’s infrastructure and collects key data, such as the location of each endpoint. Armis then scans the network traffic that these systems generate to look for potential compromises.

The platform searches for threats by comparing system activity against the startup’s Device Knowledgebase, a cloud backend that contains security-related data from 46 million endpoints. Armis detects malware, rogue devices connected to the network without authorization and software vulnerabilities.

Security teams can set policies in Armis to specify how different breach scenarios should be handled. An administrator could, for instance, configure the platform to cut off employee laptops from the corporate network if they’re suspected of being infected with malware. Armis carries out remediative action by sending instructions to an organization’s firewalls and other existing network protection tools.

One of the drivers behind the platform’s rapid adoption is that the startup competes for customers in a wide range of segments. Armis’ software can monitor the barcode scanners retailers use in their warehouses, manufacturers’ industrial equipment and MRI machines at hospitals, among many other devices.

The startup has also made it relatively simple to make its platform work with such endpoints. Armis uses an agentless monitoring approach, meaning administrators don’t have to install any extra software on the devices they want to protect. That’s an especially big time-saver when it comes to legacy and low-powered devices not originally designed to run external applications. 

Armis has raised $112 million in funding to date.
