THE AI-driven scramble is fuelling a record-breaking surge in cybersecurity M&A in 2026. The latest Momentum Cyber report notes 117 deals announced in the most recent quarter, with a broad shift in buyers: not only traditional cybersecurity players, but competing interests from outside the sector are active in acquiring AI-enabled security capabilities.
Momentum’s data highlights key acquisition themes such as identity and access management, non-human identity, data security, agentic security, runtime protections, and OT-focused security. The market is being accelerated by advances in AI for security and the rise of AI-automated attacks, creating urgency for firms to adopt AI-native capabilities through acquisitions rather than solely organic growth.
The article points to notable moves that illustrate the trend: Cyera’s $1 billion purchase of Oasis Security and Cisco’s dual buys of Astrix Security and WideField Security demonstrate the appetite to bolt AI-driven security stacks onto existing offerings. Founders and investors are rushing deals as the incubation cycle tightens; private equity and hyperscalers are increasingly seen as buyers of cyber capability.
The piece also notes a broader market context, including stock moves during early 2026 that reflected anxiety over AI’s impact on SaaS, followed by a recovery in cybersecurity equities as fears subsided. In Q3 2026, M&A activity peaked at 117 transactions for the year so far, signalling that, even as financing slows or concentrates on larger rounds, the demand for AI-enabled security capabilities continues to power deal momentum across a widening field of buyers.
