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.

R-Vision SIEM Debuts at Standoff 17 Cyber Battle and Processes 8.8 Million Correlation Events

R-Vision presented its SIEM solution for the first time at the Standoff 17 cyber exercise, where the akPots team used it to monitor a telecom operator infrastructure and investigate incidents. The product was deployed in two weeks, with 80 percent of required event sources already supported out of the box. During four days of continuous attacks the system triggered 46 correlation rules, generated more than 8.8 million correlation events and 40 thousand alerts, while analysts created 13 custom widgets and executed over 9,000 search queries. Resource consumption remained low, with the collector averaging 0.7 CPU and 1.9 GB RAM even under peak load. Participants rated the solution 4 or 5 out of 5 and highlighted raw-text search, the RQL query language and event grouping as the most useful features. The exercise also identified areas for interface and alert-description improvements.
