2026 started with a raft of merger and acquisition (M&A) activity in the cybersecurity industry and the strong focus on AI-based acquisitions has continued into the new year.
Several leading cybersecurity vendors have now completed or announced plans to buy, or merge with, other vendors and service suppliers.
CrowdStrike, Palo Alto Networks and Infoblox were among those who made M&A announcements in January. The first month of 2026 follows what was a strong year for M&As involving information security companies in 2025.
Here is Infosecurity’s cybersecurity M&A roundup for January 2026.

“This is identity security built for the AI era,” said George Kurtz, co-founder and CEO of CrowdStrike.
