Top 10 Network Operations
Network operations tools provide intent-based networking, network automation, topology discovery, traffic analysis, and performance monitoring for enterprise and cloud networks.
Why this category matters
Networks underpin every application, and manual CLI-driven management cannot keep pace with modern infrastructure velocity. NetOps tools bring DevOps principles to networking through automation, version control, and continuous validation.
When to use these tools
Invest in network operations tooling when managing multi-vendor environments, when network changes are a deployment bottleneck, or when visibility into application traffic paths is needed.

Network Operations — FAQ
What is intent-based networking?
Intent-based networking lets operators declare desired network behavior in high-level policies, and the system translates those intents into device configurations and continuously validates them.
How does NetBox differ from traditional IPAM tools?
NetBox is an open-source network source of truth that covers IP address management, device inventory, rack layouts, and circuit management, with an API-first design suited for automation workflows.
What is network telemetry and how do tools like Kentik use it?
Network telemetry streams flow data, SNMP counters, and BGP state from devices. Kentik ingests and analyzes this data at scale to provide traffic visibility, DDoS detection, and capacity planning.
