Rubrik RBRK is benefiting from the rapid expansion of its cloud security platform, which has become a key driver of its growth and market leadership in cyber resilience. In the second quarter of fiscal 2026, Rubrik’s cloud ARR grew 57% year over year, reaching $1.1 billion, driven by the adoption of its Rubrik Security Cloud platform.
Rubrik’s expanding portfolio has been a major growth driver of its success. The company recently launched “Rubrik Agent Cloud”, a new solution aimed at speeding up the adoption of AI agents in enterprises while addressing security and compliance risks. Built on the Rubrik Platform, it offers full lifecycle management for AI agents. This includes real-time monitoring, policy enforcement, and rollback features to ensure secure, accurate, and resilient AI operations.
Rubrik’s focus on innovation further strengthens its cloud security platform. In the second quarter of fiscal 2026, Rubrik acquired Predibase to speed up the use of agentic AI. This gives organizations a platform to easily customize models based on their data and run them on an optimized inference stack. This approach improves accuracy, lowers costs and automates data governance.
Rubrik’s strong demand for its data security solutions and growing client base are expected to benefit the company’s top-line growth. For the third quarter of fiscal 2026, RBRK’s revenues are expected to be between $319 million and $321 million, reflecting a year-over-year growth rate of 35% to 36%.
