Virtana Acquires Zenoss to Deliver the Industry's Deepest and Broadest Observability Platform

PALO ALTO, Calif. - May 14, 2025 - Virtana, the leader in deep hybrid-infrastructure observability, today announced it has acquired Zenoss, a pioneer in real-time IT service monitoring and a leader in AI-powered event intelligence. This strategic acquisition aims to bridge the gap between service visibility and infrastructure control in hybrid environments. The increased scale of Virtana and Zenoss will enable greater opportunity for accelerated investment and innovation.

The combined entity introduces the industry's broadest, deepest, and most unified observability platform, empowering IT and risk management teams to trace incidents from business-service impact to underlying infrastructure behavior through a single, AI-powered lens. By correlating real-time user impact, service topology, and hybrid infrastructure telemetry, this integration enables customers to quickly pinpoint failures, performance issues, and cost drivers, eliminating blind spots and accelerating resolution.

The combination positions Virtana to address a rapidly expanding observability and hybrid cloud monitoring market, expected to surpass $19 billion by 2028, according to industry estimates. As enterprises shift toward hybrid and multicloud environments and demand unified, AI-driven operational insights, Virtana is uniquely equipped to deliver the breadth, depth, and intelligence modern IT teams require to drive resilience, efficiency, and business success.

"This acquisition isn't just an expansion of our capabilities, it's a strategic shift toward end-to-end control over hybrid infrastructure performance, cost, and risk — closing existing gaps in observability," said Paul Appleby, CEO and president of Virtana. "By bringing Zenoss' service-centric event intelligence together with Virtana Platform's deep infrastructure and cost analytics, we're eliminating the blind spots left by legacy monitoring tools. We're excited to join forces with Zenoss to continue Virtana's mission in driving innovation within observability."

Greg Stock, CEO of Zenoss, added, "Large enterprises, government institutions, and managed service providers rely on Zenoss to keep mission-critical services running. The combination of Zenoss and Virtana gives our customers and partners access to broader visibility, deeper infrastructure analytics, and a unified strategy for improving resilience, performance, and operational efficiency. This is a huge day for Zenoss — we're thrilled to be joining the Virtana team."

Why the Combination Matters:

• Unified Observability - The combination of Virtana and Zenoss creates the first platform to provide Full-Stack Observability from top-level services to the deepest level infrastructure. Virtana offers deep insights from over 16,000+ metrics for infrastructure and container observability, while Zenoss provides enhanced event intelligence for hundreds of out-of-the-box infrastructure and application services.
• AI-Driven Resilience - Combines Zenoss' model-informed AIOps with real-time IT service mapping, event correlation, and real-time topology visualization with Virtana's agentic AI and machine-learning models for capacity and cost optimization. These capabilities expand intelligent automation and accelerate predictive root-cause analysis and remediation.
• Proactive Prevention - While some system disruptions are caused by external cyberattacks, most result from internal failures—misconfigurations, capacity limits, cascading service degradation, or delayed detection. The combined platform helps IT and operations teams surface issues earlier, understand their impact faster, and take action before they disrupt business continuity.
• Operational Efficiency - Customers have achieved up to 95% faster MTTR and 99.999% uptime by combining early warning signals with AI-driven event intelligence that accelerates root-cause analysis, enabling IT leaders to fix problems faster, forecast risk, prioritize investments, and justify spend with data-backed precision.
• Unique Market Position - The deepest and broadest hybrid observability platform for on-premises infrastructure, legacy data center workloads, containerized microservices, and multicloud resources, eliminating tool sprawl and simplifying platform consolidation and modernization strategies.
• Accelerated Innovation Road Map - Combined R&D capabilities fast track forthcoming features, including automated remediation and optimization for AI and ephemeral workloads, all within the Virtana Platform.

Commitment to Customers and Partners:
Virtana and Zenoss share a vision that actionable observability must scale with complexity, align to business outcomes, and reduce operational burden. Together, we're expanding our go-to-market presence and customer reach across key industries, including financial services, health care, telecommunications, and the public sector, backed by a proven track record of delivering outcomes for Global 2000 enterprises. Upon closing, the companies will operate as one organization under the Virtana brand, fully supporting current offerings while accelerating a shared road map that integrates the best of both platforms into a next-generation unified observability solution.
