# Best Container Networking Software *By [Adam Crivello](https://research.g2.com/insights/author/adam-crivello)* Container networking software creates a virtualized, defined network to facilitate container-to-container connectivity. These internally virtualized networks allow communication and integration between containers or applications powered by container sets. The networks create isolated regions to allow multiple containers to communicate with the same network independently. Companies utilize these solutions for increased scalability and data accessibility of applications. They provide a higher level of [security](https://research.g2.com/blog/g2-on-cloud-security-conquering-container-security) and increased capability for service discovery, essentially powering the microservices industry through linked container applications. Container networking software can increase the functionality of [container management software](https://www.g2.com/categories/container-management) and [container orchestration software](https://www.g2.com/categories/container-orchestration) solutions by connecting designated applications. To qualify for inclusion in the Container Networking category, a product must: - Create isolated networks for container instances - Connect containers through designated networks - Provide security layers for application networks - Allow privileged external connectivity - Allow for IP address management ## How Many Container Networking Software Products Does G2 Track? **Total Products under this Category:** 26 ### Category Stats (May 2026) - **Average Rating**: 4.36/5 - **New Reviews This Quarter**: 15 - **Buyer Segments**: Mid-Market 47% │ Small-Business 35% │ Enterprise 18% - **Top Trending Product**: HAProxy (+0.003) *Last updated: May 22, 2026* ## How Does G2 Rank Container Networking Software Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 1,600+ Authentic Reviews - 26+ Products - Unbiased Rankings G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts.
