Distribute Elastic Endpoint Artifacts via NetEye Satellites

In real-world security environments, “simple” rarely means simple. As a technical consultant, I often see Elastic Defend deployed within infrastructure that’s anything but standard: segmented networks, restricted outbound connectivity, compliance-driven isolation, and operational constraints that make direct internet access impossible for managed endpoints. One recurring requirement in these environments is the local delivery of Elastic…

Postfix is ​​not typically the first component that comes to mind when talking about critical services. And yet it’s through Postfix that all notifications, ticketing system-related correspondence, and monthly SLA reports are sent out from NetEye.

Inside Elastic Security Detection Rules: Internal Structure & Upgrade Mechanics

A Rule Is More Than a Query In modern detection engineering, a rule is often misunderstood as just a query that triggers alerts. In reality, within Elastic Security, a detection rule is a structured, versioned, and lifecycle-managed object that goes far beyond simple query logic. Understanding this structure is essential for anyone operating in a…

One Elastic Fleet Policy, Multiple Behaviors: Selective Agent Configuration with Agent Providers

In many Elastic deployments, the natural approach every time you encounter a server with different needs is to create a new Fleet policy. Each group seems to require its own small set of tweaks or additional integrations. But the more policies you create, the harder it becomes to maintain and scale your configuration. In reality…

Elastic Integration: Which New Features Can Be Activated?

From a Technical Consultant’s Perspective “How can I tell if a new Elastic Integration feature or PR is already included in my NetEye version?” Elastic adds new features quite often.
