Armis, a cyber exposure management and security company, has completed a pre initial public offering (IPO) funding round, raising $435m and bringing its valuation to $6.1bn.

Led by Growth Equity at Goldman Sachs Alternatives, the funding round also saw participation from CapitalG, new investor Evolution Equity Partners, and various existing investors.

The proceeds from this financing round will support Armis’s three-year roadmap as it prepares for an IPO and works towards achieving $1bn in annual recurring revenue (ARR).

The California-based cybersecurity firm plans to use these funds to advance product development, grow its go-to-market strategy, and pursue further strategic acquisitions.

Growth Equity at Goldman Sachs Alternatives managing director Irit Kahan said: “Armis is a truly differentiated cybersecurity platform with exceptional growth momentum.

“We believe the platform is redefining cyber exposure management by providing a comprehensive and unified layer of visibility, turning blind spots into sources of intelligence.”

Founded in 2016, Armis provides cybersecurity for devices and systems used across critical infrastructure worldwide. Its Armis Centrix platform offers continuous asset visibility, threat intelligence, and control from on‑premises environments to the cloud.

The company’s tools are designed to help organisations manage cyber risk and maintain the availability of essential services.

The investment round comes as Armis reports annual recurring revenue (ARR) exceeding $300m, with its cyber exposure management offering seeing more than 50% growth year-over-year.

Armis CEO and co-founder Yevgeny Dibrov said: “This round marks another defining moment in our journey to build a category-defining cybersecurity company.

“Our growth proves that organisations are embracing a unified, exposure-based approach to security, and the round signals investors’ belief in Armis as a leader in cybersecurity. At the heart of Armis is a team driven by one goal: putting our customers first.”

Armis stated it works with over 40% of Fortune 100 companies and seven of the Fortune 10, serving sectors including manufacturing, aviation, financial services, healthcare, and government.

In the past two years, Armis has completed three mergers and acquisitions (M&A) deals focused on cloud, AI, and operational technology (OT) security.

In October 2025, Armis announced an expanded partnership with Fortinet, designed to help enterprise security teams streamline their security architecture and automate response across complex networks.

Through this collaboration, Armis and Fortinet deliver asset visibility, risk management, policy enforcement, and automation features aimed at improving cyber resilience for large organisations.

In March 2025, Armis acquired Otorio, an Israel-based company specialising in OT and cyber physical systems security.
