Largest-ever deal aims to strengthen AI-era defenses, even as investors question deal pace
ServiceNow (SNOW) announced Tuesday that it has agreed to acquire cybersecurity startup Armis for $7.75 billion, marking the enterprise software company’s largest acquisition to date. The deal underscores ServiceNow’s push to expand its security and risk offerings as artificial intelligence adoption accelerates the scale and sophistication of cyberattacks across industries.
Through the acquisition, ServiceNow plans to integrate Armis’ core capabilities—including device discovery, continuous asset monitoring, and advanced threat detection—into its broader platform. These tools are increasingly critical as organizations struggle to protect sprawling digital environments that include cloud infrastructure, unmanaged devices, and connected systems. Recent high-profile cyber incidents affecting major companies have heightened urgency around proactive, AI-ready security solutions.
Despite the strategic rationale, ServiceNow shares fell about 3% following the announcement, reflecting investor unease over the company’s growing appetite for large acquisitions. ServiceNow has been on an aggressive buying streak, recently acquiring identity security firm Veza, AI startup Moveworks, and sales automation platform Logik.ai. The company closed its $2.85 billion acquisition of Moveworks earlier this month, adding to concerns about capital allocation and integration risk.
ServiceNow Chief Financial Officer Gina Mastantuono sought to reassure investors, saying the Armis deal completes the company’s core security stack. She noted that with Armis on board, ServiceNow does not anticipate further major acquisitions in the security space, signaling that the current expansion phase may be nearing its end.
The company expects the transaction, which is slated to close in the second half of 2026, to significantly expand its addressable market. Management said the deal could triple the market opportunity for ServiceNow’s security and risk business, positioning the company more competitively as enterprises seek unified platforms that combine workflow automation, governance, and cybersecurity.
Industry analysts view the move as a calculated effort to stay ahead of rivals. Rebecca Wettemann, CEO of advisory firm Valoir, said ServiceNow’s acquisition strategy reflects a desire to gain an edge in orchestration and governance by securing intellectual property, technical leadership, and established customer bases rather than building everything internally.
For Armis, the deal comes as the fast-growing startup was preparing for an initial public offering. Founded in 2015, Armis crossed $300 million in annual recurring revenue in August and recently outlined a three-year plan to reach $1 billion in ARR. The company was valued at $6.1 billion in a November funding round led by Goldman Sachs’ alternative investment platform, with participation from CapitalG.
As AI reshapes both enterprise operations and cyber threats, ServiceNow’s bold acquisition signals its intent to be a central player in securing the digital enterprise—even if that ambition comes with short-term market skepticism.
