Agentic NetOps: The Right Direction, and the Real Work Ahead
NetBrain’s big announcement was so big, it took over the Sphere. But this was Cisco Live, so let’s talk about what Cisco had to say too. In his keynote, Jeetu...
Network leaders know that even a small configuration change can have ripple effects across the entire enterprise infrastructure. In today’s complex, multivendor environments, a single update—whether it’s a new firmware version, a security policy tweak, or a shift in application traffic paths—can unintentionally disrupt business-critical services or open new security vulnerabilities. The stakes are high: a misstep can trigger widespread outages, performance degradation, or compliance failures.
Yet, keeping pace with constant change is non-negotiable. As organizations evolve, so do their networks—through equipment upgrades, cloud migrations, and ongoing vendor-driven updates. The real challenge for network leaders is not just managing these changes, but understanding their systemwide impact before they go live. This is where network digital twins come into play.
Why Network Digital Twin and Infrastructure Assurance Matter
Gartner projects that “Through 2028, organizations using network digital twins to model their configuration and software/firmware updates will reduce their unplanned outages by 70%.”
By creating a virtual replica of the entire network, digital twins allow leaders to simulate and validate configuration changes in a risk-free environment. But building and leveraging these models is no small feat. In this post, we’ll explore the unique challenges network teams face in predicting and controlling the systemwide effects of configuration changes—and how digital twins are poised to transform this critical aspect of network management.
Network digital twins are gaining popularity because they provide a cost-effective, automated, and reliable way to manage the growing complexity of modern networks, reduce risk, ensure compliance, and support agile business needs-all while minimizing downtime and operational costs.
We’re excited to share that NetBrain has been recognized in Gartner’s 2025 Leverage Network Digital Twins to Increase Agility and Lower Risk research.
This recognition highlights our dedication to empowering organizations to automate network discovery, mapping, and documentation; create automation in a turnkey manner; and proactively identify and resolve network issues before they impact business operations.
What Is a Network Digital Twin?
According to Gartner, “A network digital twin, by definition, is a model of the behavior of campus, software-defined WAN (SD-WAN) or data center network components, deployed as a stand-alone application or integrated into a larger management or security application.”
These models help network teams:
- Avoid outages from config drift or firmware changes
- Simulate and test policy and architecture changes
- Safely adopt new vendor equipment in multivendor environments
- Eliminate the need for costly “shadow IT” testing labs
NetBrain’s Digital Twin
NetBrain’s Digital Twin stands out for its comprehensive, real-time modeling and automation.
- Golden State & Config Layer:
Captures and enforces golden configurations and compliance standards,
ensuring network intent aligns with best practices and security protocols.
- Path Layer:
Monitors and analyzes live, baseline, and historical end-to-end traffic flows, calculating end-to-end forwarding paths and identifying bottlenecks or performance issues. - Topology Layer:
Visualizes the physical and logical structure of the network, mapping all connections, dependencies, and relationships at Layer 2/3 and across overlays. - Device Layer:
Real-time inventory and status of all network devices, including configurations, resource utilization, and software versions across traditional, virtual, and cloud components.
NetBrain’s dynamic network modeling and automation capabilities are central to achieving this vision, enabling:
- Real-time visibility and observability across hybrid, SDN, SD-WAN, and cloud environments
- Automated network discovery, mapping, and documentation, eliminating manual processes and static diagrams
- Continuous compliance enforcement and security validation through intent-based automation and AI-powered insights
