What Zenoss does

Zenoss is a real-time IT service monitoring and observability software provider founded in 2005 and headquartered in Austin, Texas. The company's core platform provides unified visibility across cloud, virtual, and physical IT environments through real-time service modeling, dependency mapping, and impact analysis. Its proprietary features include AI-assisted root-cause analysis, predictive analytics and AIOps, intelligent automation across IT operations workflows, and an extensible ZenPack framework for adding monitoring capabilities. The platform targets large enterprise IT organizations that require comprehensive observability and proactive issue prevention across hybrid infrastructure.

Zenoss generated quantifiable operational outcomes for customers including an 85% improvement in Mean Time to Resolution (MTTR), a 99.99% reduction in alert noise, and a 70% increase in ITOM system automation. The platform integrates with major ITSM/DevOps tools (ServiceNow) and infrastructure partners including AWS, NetApp, Dell Technologies, Cisco, Nutanix, Pure Storage, Infinidat, Hitachi, and AppDynamics. Zenoss raised approximately $57M+ in cumulative disclosed funding across multiple rounds from 2006 to 2023, with notable investors including Boulder Ventures, Grotech Ventures, Industry Ventures, Intersouth Partners, Maryland Venture Fund, and Summit Partners. Greg Stock serves as Chairman & CEO.

In May 2025, Zenoss was acquired by Virtana, a Palo Alto-based hybrid-infrastructure observability company. Following the acquisition, Zenoss's technology was integrated into the Virtana Platform as the Service Observability module, and Zenoss Service Dynamics was rebranded as Virtana Service Dynamics. The combined entity operates under the Virtana brand and targets the observability and hybrid cloud monitoring market expected to surpass $19 billion by 2028. Pricing details have not been publicly disclosed.

Core offering

Zenoss develops real-time IT service monitoring and analytics software that delivers unified visibility across cloud, virtual, and physical IT environments. Its platform combines service modeling, dependency mapping, and AI-assisted root-cause analysis to help enterprise IT operations teams prevent disruptions, reduce alert noise, and accelerate incident resolution. Following its May 2025 acquisition by Virtana, Zenoss technology is delivered as the "Service Observability" module within the Virtana unified hybrid observability platform.

Product overview

Zenoss is now fully integrated into the Virtana Platform as Service Observability. The Virtana Platform is a unified hybrid observability platform composed of multiple integrated modules: Global View AIOps, Infrastructure Observability, Application Observability, Service Observability (formerly Zenoss), AI Factory Observability, and Virtana Copilot. Service Observability builds on core Zenoss capabilities—service modeling, dependency mapping, and impact analysis—and extends them with Virtana's AI-powered root cause intelligence, predictive analytics, and deeper integration across infrastructure, containers, and AI workloads. The platform correlates signals across domains to cut noise, pinpoint issues faster, and automate recovery. Virtana Service Dynamics (formerly Zenoss Service Dynamics) provides flexible deployment options available on-prem or in the cloud.
