Armis Inc., the developer of a device detection and protection platform for enterprises, has raised $200 million in funding to support its growth efforts. 

The company announced the investment today. It said that the capital came from General Catalyst, Alkeon Capital Management, Brookfield Technology Partners and Georgian. The Series D raise values Armis at $4.3 billion, $1.3 billion more than what it was worth following its last funding round in 2021.

In a large corporate network with thousands of devices, some endpoints can escape the attention of administrators. That means any vulnerabilities they may contain go unnoticed as well. Armis provides a software platform, Centrix, that automatically maps out the devices in a corporate network and scans them for cybersecurity issues.

The platform can find employee endpoints, printers, servers and network equipment. After it spots a new device, Centrix searches for vulnerabilities such as unpatched firmware with a known security flaw. The platform then ranks those vulnerabilities by severity to help administrators prioritize their remediation efforts.

Centrix also spots more subtle cybersecurity issues. The platform can identify situations where a device doesn’t have an antivirus installed, or does have one but can’t make full use of its features because of networking problems. Some antivirus tools rely on a cloud-based backend to work, which means they can’t find malware if the system on which they’re running lacks an internet connection.

Armis says its platform’s focus is not limited to cybersecurity issues. According to the company, Centrix is also capable of detecting devices that fail to comply with the European Union’s GDPR privacy law. For healthcare organizations, Armis provides a feature that alerts administrators when the U.S. Food and Drug Administration recalls a medical device.

Device issues were historically difficult to detect because of the way that telemetry is collected. Typically, cybersecurity tools track a company’s hardware assets by analyzing the network traffic they generate. The challenge is that many systems, particularly industrial and medical devices, generate network traffic only sporadically, which creates few opportunities to collect telemetry. 

Armis says that Centrix tackles the challenge with a mechanism called Smart Active Querying. According to the company, the feature collects data about devices directly without relying on network traffic analysis. It can glean what a device is used for, whether the firmware it’s running is up-to-date and other technical details.

Today’s funding milestone comes about three months after Armis disclosed that its annual recurring revenue has topped $200 million. It reached the $100 million mark only 18 months earlier. To maintain that momentum, Armis will use its new capital to speed up product development and explore acquisition opportunities.

The company hopes the new funding round will help it grow to $500 million in annualized recurring revenue by 2026. According to Bloomberg, it intends to go public the same year. Sources told Reuters it has already started preparing for the offering.
