Every packet flowing through a Corelight sensor contains both security-relevant data and performance-relevant data. Until now, Corelight has focused exclusively on extracting security value from network traffic: connection logs, protocol analysis, and threat detections. But the same traffic that reveals lateral movement also reveals TCP latency. The same DNS queries that surface potential C2 channels also reveal resolution timing.

Agentic AI is evolving from assistants that answer questions into systems that can remember, use tools, call APIs, interact with SaaS applications, and improve over time. Hermes Agent, developed by Nous Research, reflects this shift as a self-improving agent that can create skills, persist knowledge, and build context across sessions., reflects this shift as a self-improving agent that can create skills, persist knowledge, and build context across sessions.

For connecting physical servers and computers to a network, you need physical network adapters, switches, and routers. With virtual machines, virtual network concepts are used for communication between the different components of an infrastructure. The proper configuration of ESXi networking on a host is critically important to the configuration of any ESXi environment. Generally, ESXi host networks include storage, vMotion, VM, and management networks.

Corelight Sensor v29.1 and Fleet Manager v29.1.1 fundamentally expand what a Corelight Sensor delivers. The release turns existing network evidence into a shared source of truth for SecOps, NetOps, triage, and forensic investigation. Network performance monitoring and asset classification unlock new value from traffic you're already collecting.

Cato CTRL recently analyzed an operator’s command-and-control (C2) server’s entire 33 days operation, including the steps he took to preserve access after the takedown. 339 commands. Four French victims. Between March 30 and May 1, 2026, Cato CTRL studied every command issued by a French-speaking threat actor (“Poisson”) against one French automotive small business and four French individuals.

A CVE lands in the morning. Hours later, attackers are exploiting it in the wild. The patch is not ready, the change window is days away, and the clock is already running. None of this is new. What changed is that vulnerability exploitation is now the most common path into organizations.
