Armis Security Completes $100 Million Secondary Round, Valuation Rises to $4.5 Billion

Cybersecurity leader Armis Security has completed a $100 million secondary share sale, raising its company valuation to $4.5 billion, up from $4.3 billion in its previous funding round last October. Georgian, a long-time investor in the company, led the secondary round.

Unlike previous rounds, the latest transaction did not involve founders or institutional investors, but rather allowed hundreds of long-time employees in Israel and abroad to sell part of their holdings—about 15% of their shares. A similar employee-focused secondary offering took place in April 2024.

Backed by Major Global Investors

The October 2024 round, which brought in $200 million, was led by General Catalyst, Alkeon Capital, Brookfield, and Georgian, and included participation from existing backers such as Insight Partners, CapitalG (Alphabet's growth fund), and One Equity Partners.

Armis’ sustained backing by prominent investors highlights its continued momentum in a fast-evolving cybersecurity market, especially in protecting complex IT and operational technology (OT) systems.

Acquisition-Driven Expansion

Over the past year, Armis has aggressively expanded through strategic acquisitions aimed at strengthening its platform capabilities:

• Autorio (March 2025): Acquired for $120 million, the Israeli firm specializes in protecting industrial systems and cyber-physical environments. It is already generating significant revenue for Armis.

• Silk Security (April 2024): Bought for $150 million, Silk developed a risk management platform for cyber exposure. The company was reportedly producing tens of millions in revenue within a year of acquisition.

• CTCI (February 2024): An American firm purchased for $20 million, it uses AI to identify cyber threats.

These acquisitions position Armis to further dominate the market in asset intelligence and automated threat detection across hybrid environments.

Strong Revenue Trajectory and IPO on the Horizon

Armis reported $200 million in revenue in October 2024 and ended the year with sales exceeding $250 million. Market analysts expect the company to reach $500 million in annual revenue by 2026, making it a strong candidate for an initial public offering (IPO) that year.

Global Client Base and Workforce

Founded in 2016 by CEO Yevgeny Dibrov and CTO Nadir Yizreel, Armis employs about 850 people worldwide, with teams based in Israel and across global markets.

Armis’ growing customer list includes major global organizations such as:

• United States Postal Service (USPS)

• United Airlines

• Colgate-Palmolive

• Mondelez International (maker of Oreo, Milka, Toblerone)

Its platform enables organizations to see, secure, and manage critical assets, ranging from IT and OT systems to medical devices, cloud infrastructure, and source code.
