ServiceNow Inc. (NOW) is making a big bet on cybersecurity, announcing Tuesday that it will acquire Armis for $7.75 billion in an all-cash deal. The acquisition represents a major strategic move as ServiceNow expands beyond its core business into AI-powered security operations.

The deal will be funded through cash on hand and debt. As of September 30, ServiceNow had $2.73 billion in cash and cash equivalents, meaning they'll need to tap the debt markets to close this one. The transaction is expected to close in the second half of 2026, pending regulatory approvals, with Armis' team joining ServiceNow.

Why Armis Matters

Armis specializes in cyber exposure and cyber-physical security, which is a fancy way of saying they protect not just your typical IT infrastructure, but also operational technology, medical devices, and other critical connected systems. Think factory floors, hospital equipment, and infrastructure that governments rely on. These are the environments where a cybersecurity breach doesn't just mean leaked data—it can mean actual physical consequences.

For ServiceNow, this acquisition strengthens its security workflow capabilities and enables what they're calling AI-native, proactive cybersecurity with automated vulnerability response across all connected devices. The combined entity will deliver an end-to-end security operations stack that integrates real-time asset discovery, threat intelligence, risk prioritization, and automated remediation across entire technology ecosystems.

The Market Opportunity

Timing matters here. Security has become the top priority for CEOs as AI adoption accelerates, and the numbers back that up. Global spending on information security is projected to hit $240 billion in 2026, representing a 12.5% increase. Companies are realizing that as they deploy more AI systems and connect more devices, their attack surface expands dramatically.

ServiceNow's Security and Risk business already surpassed $1 billion in annual contract value in the third quarter of 2025. With the Armis acquisition, the company expects to more than triple its security market opportunity and accelerate its autonomous, proactive cybersecurity capabilities.

The Agentic AI Angle

Amit Zavery, president, chief operating officer, and chief product officer at ServiceNow, framed the deal in terms of what he calls the "agentic AI era." He explained: "In the agentic AI era, intelligent trust and governance that span any cloud, any asset, any AI system, and any device are non-negotiable if companies want to scale AI for the long-term. Together with Armis, we will deliver an industry-defining strategic cybersecurity shield for real-time, end-to-end proactive protection across all technology estates. Modern cyber risk doesn't stay neatly confined to a single silo, and with security built into the ServiceNow AI Platform, neither will we."

In other words, if you're going to let AI agents run around your enterprise making decisions and taking actions, you need security that can keep up with them across every possible system and device.
