ServiceNow has announced that it will acquire Armis, a specialist in operational technology (OT) and connected-device security. The deal is valued at $7.75 billion and will be paid fully in cash. This is the largest acquisition ServiceNow has made so far. The move signals a stronger push by the company into the cybersecurity space.
The acquisition was announced in December 2025 and is expected to close in the second half of 2026. Completion of the transaction depends on regulatory approvals and other customary closing conditions. Until the deal is finalized, both companies will continue to operate separately. ServiceNow has said it will share more details as the process moves forward.
Armis is widely known for protecting devices that are often missed by traditional security tools. These include industrial systems, operational technology, medical devices, and other internet-connected equipment. Its platform helps organizations discover all connected devices in real time. It also identifies risks and security gaps across complex environments.
ServiceNow plans to integrate Armis’ technology into its existing cloud and workflow platform. The aim is to give customers a single system that can see risks, assess their impact, and trigger automated responses. This integration is expected to improve how organizations manage security incidents. It also reduces the complexity of using multiple disconnected tools.
The deal comes at a time when cyber risks are rising due to rapid adoption of AI and connected technologies. As companies deploy more smart systems, the number of potential entry points for attackers increases. ServiceNow believes better visibility across all devices is now critical. Armis is expected to help address this growing challenge.
Founded in 2015, Armis has expanded quickly over the past few years. Before the acquisition announcement, the company had crossed $340 million in annual recurring revenue. It was also reported to be preparing for a potential public listing. Instead, Armis chose to join ServiceNow as part of a larger platform.
ServiceNow’s leadership described the acquisition as a major step in strengthening its security portfolio. The company sees cybersecurity as a central pillar of its long-term growth strategy. By adding Armis, ServiceNow aims to offer end-to-end protection across both IT and OT environments. This could help customers simplify how they manage cyber risk.
After the announcement, ServiceNow’s share price dipped slightly as some investors reacted to the size of the deal. Large acquisitions often raise short-term concerns around cost and integration. However, analysts note that the move significantly expands ServiceNow’s security capabilities. Once completed, the deal is expected to strengthen ServiceNow’s position in the global cybersecurity market.
