Inside the $8 billion cybersecurity acquisition that rescued ServiceNow from the ‘Saaspocalypse’

ServiceNow’s $7.75 billion cash acquisition of Armis in April 2026 — the largest deal in the company’s history — has become a central plank in the vendor’s strategy to counter investor fears of a so-called “SaaSpocalypse.” Armis, co‑founded by Yevgeny Dibrov and Nadir Izrael, provides device visibility and risk detection across enterprise networks, flagging insecure medical devices, industrial systems and other Internet of Things endpoints. The deal handed Dibrov and Izrael roughly $930 million between them and was folded into a new Autonomous Security and Risk unit alongside sister buy Veza.

“We did not really believe in this SaaS apocalypse,” Amit Zavery, ServiceNow’s chief product officer, president and chief operating officer, told reporters, adding that the company saw the period as an opening rather than an existential threat.

How an Israeli duo helped reshape a $180 billion company

The Armis purchase came after a turbulent stretch for ServiceNow: when news of the deal leaked in mid‑December the stock opened down about 9%, echoing broader investor anxiety that AI agents could make traditional enterprise software obsolete. ServiceNow’s shares had fallen as much as 42% in the first four months of 2026, a drop larger than some peers. By May, however, shares surged 41% and rallied again after a strong second quarter, when the company reported revenue of $3.99 billion, up 24%, and said its AI products crossed $1 billion in annual contract value.

Armis’s core capability — continuous monitoring of every connected device on an enterprise network — neatly complements ServiceNow’s IT service management footprint. Zavery said the acquisition “is helping, for sure,” while stressing it is one part of a broader strategy to combine cybersecurity, IT asset management and industrial monitoring on a single platform.

Background: from army barracks to tech exits

The relationship between Armis’s leaders stretches back to the Israeli Defense Forces. Assaf Rappaport, who ran an elite technology unit, recruited a young Yevgeny Dibrov after hearing that he “can probably do everything.” Rappaport later became Dibrov’s commanding officer; the two cultivated a working partnership that led to multiple startups.

• Before Armis, Dibrov worked with Rappaport at Adallom, a company that monitored employee behavior inside cloud apps; Microsoft acquired Adallom in 2015 for $250 million.
• Dibrov, who ran Adallom’s business development across Europe, the Middle East and Asia despite having no formal sales training, studied electrical engineering and computer science at Technion.
• After the Armis exit, Dibrov became general manager of the Armis business unit inside ServiceNow; Izrael took the role of group vice president of product and engineering.

Outlook

ServiceNow has credited the Armis and Veza integrations with “supercharging” its security business and has folded both into Autonomous Security and Risk as direct contributors to growth. Executives point to the deal as proof that combining device‑level security with IT service workflows can boost enterprise resilience and revenue. Whether that strategy quells sustained investor anxiety about AI’s impact on traditional software vendors will depend on execution: integrating product stacks, converting cross‑sell opportunities into contracts, and proving that device visibility converts to measurable risk reduction for large customers.
