Rubrik sells cybersecurity software to enterprises and governments. Its core product is the Rubrik Security Cloud (RSC), a cloud-native SaaS platform that combines data backup and recovery with cybersecurity into a single system. The core idea is that cyberattacks are inevitable, so organizations need to be able to rapidly recover when breached — not just detect and prevent threats. RSC secures data across enterprise workloads, unstructured data, cloud environments (AWS, Azure, GCP), SaaS applications, and identity providers. The platform creates immutable, air-gapped backups, monitors for ransomware, classifies sensitive data, and orchestrates recovery after an attack. Rubrik sells RSC through subscription tiers, targeting CIOs, CTOs, and CISOs via a direct sales force and channel partners. Rubrik's business model is land-and-expand: the company enters a customer by securing any one data category, then grows ARR through organic data growth, adding new workloads, and cross-selling additional security products like Data Security Posture Management and identity security. NRR has remained above 120%. Rubrik also sells hardware appliances for customers who self-host, though the business is predominantly SaaS. Beyond its core platform, Rubrik launched Rubrik Agent Cloud in early 2026, a new product targeting governance and control of AI agents in enterprise environments, built on top of its core platform and augmented by its acquisition of Predibase, an LLM fine-tuning platform. Rubrik Agent Cloud is in early stages with no meaningful near-term revenue expected.
