Modern networks encompass a large number of edge devices, including firewalls, load balancers, routers, and switches. Regardless of network size or type, ongoing configuration changes based on business and technical requirements are inevitable. Moreover, the network infrastructure landscape is becoming increasingly complex with the addition of cloud-based services.
Adding a rack, upgrading the operating system (OS), or adding a border gateway protocol (BGP) peer or virtual local area network (VLAN) can cause an outage with significant business repercussions. As a result, organizations require a modern, disciplined approach to network change management, ensuring compliance across all network devices and services. While scope determination, risk analysis, and peer review are manual processes, network validation is automated, accelerating the process and reducing risk by injecting consistency and discipline. Figure 1 shows the network change management process.

Moreover, with increasing security threats to network resources, enterprises must follow standard practices, ensuring configuration and security policies remain compliant with a network source of truth (NSoT) based on the latest industry standards. However, making and keeping track of each change in a multivendor networking environment comprising hundreds or thousands of network devices is overwhelming. Therefore, maintaining network compliance based on business, network, and security intent must be a priority for network administrators.
The GigaOm Key Criteria and Radar reports provide an overview of the network validation market and highlight vendors and products that excel. This Key Criteria report identifies capabilities (table stakes, key criteria, and emerging technology) and evaluation metrics for selecting a network validation solution. The corresponding Radar report provides an overview of notable network validation vendors and solutions that excel. Together, these reports offer essential insights for network automation initiatives, helping decision-makers evaluate solutions before deciding where to invest.
