K2 Cloud Adds Native OVN Traffic Mirroring for NTA/NDR Deployment in Public Cloud

K2 Cloud has implemented traffic mirroring for virtual machine interfaces inside overlay networks built on OVN, solving a long-standing gap that prevented NTA/NDR systems from operating in Russian public clouds. The company contributed the feature upstream, and the patch was accepted into the main OVN codebase. The solution supports source, destination, and mirroring session objects together with optional match/action filters that eliminate duplicate packets, reduce load on sensors, and allow traffic distribution across multiple analyzers. Testing with Positive Technologies PT NAD showed sustained throughput above 3 Gbit/s with approximately 400 000 packets per second and minimal packet loss. The feature works inside a single availability zone; multi-AZ deployments require one PT NAD sensor per zone. Management is available through the web console, an EC2-compatible API, and the official Terraform provider.
