SIEM & Threat Detection – Detecting and Defending Against Threats

Security, SIEM & Logging

Centrally collect, correlate, and respond to security-related events from servers, endpoints, the network, and the cloud. We plan, build, and operate your SIEM using Elastic, Wazuh, and Graylog—including detection and initial response via MyEngineer, if desired.

Detect Attacks Early

Suspicious patterns are correlated across all sources—before a clue turns into actual damage.

A Centralized Situation Report

Logs from servers, endpoints, the network, and the cloud are consolidated in one place—no more isolated silos.

Open source, no lock-in

Elastic, Wazuh, Graylog, and OpenSearch instead of expensive closed-source suites—full control over data and costs.

Endpoint to Network

Wazuh detects issues directly on the device, while Elastic correlates data across the entire landscape—providing a comprehensive view rather than a fragmented one.

Compliance-ready

Complete retention, searchable logs, and audit trails—the foundation for evidence and forensic analysis.

We’ll take care of it for you

MyEngineer can handle detection and initial response upon request.

The Problem

Security incidents can be predicted—but only if the warning signs all point in the same direction. Crucial clues get lost amid scattered logs and a flood of alerts.

Attacks go unnoticed

Without central correlation, the indicators are scattered across individual log silos—and an ongoing attack isn’t detected until it’s too late.

Too many alerts, not enough signals

Individual tools constantly trigger alerts, but without prioritization and context, the actual incident falls through the cracks.

Duty to Provide Evidence

Without complete, searchable logs, there is no basis for audits, compliance, and a thorough forensic investigation.

How we work with you

Four steps, identical for every NETWAYS solution—from use cases to an operational SIEM with a defined response process.

Step 1

Analysis & Concept

We assess security needs, relevant log sources, and compliance requirements, and define the most important detection use cases.

→ Identify where your actual risk lies—not based on gut feeling.

"

Step 2

Setup & Integration

We're setting up the SIEM: connecting log sources, deploying Wazuh agents, and configuring correlation rules in Elastic.

→ A clean pipeline instead of a patchwork of individual scripts.

"

Step 3

Commissioning & Detection

Go-live: Suspicious patterns trigger alerts, which are followed by a clearly defined response process.

→ Clear procedures instead of guesswork in an emergency.

"

Step 4

Support & Operations

Upon request, we can handle operations and monitoring via MyEngineer or provide your team with support and training.

→ A powerful SIEM without having to set up your own SOC.

What Your SIEM Does

From the central collection to the response—the building blocks are interconnected and can be introduced step by step.

Security Monitoring

Collect data centrally

Logs from servers, endpoints, the network, and the cloud are collected centrally and normalized—creating a common data source.

Result: No more scattered, incomparable sources.

Threat Detection

Detect & Correlate

Rules and correlation in Elastic detect suspicious patterns across multiple sources—based on MITRE ATT&CK.

Effect: Actual attacks stand out from the background noise.

Endpoint Detection (EDR)

Securing Endpoints

Wazuh handles detection directly on the device, as well as integrity and compliance checks on servers and clients.

Effect: Detect threats as soon as they arise.

Incident Response

Respond & Escalate

Alerts trigger a defined response process—with detection and response via MyEngineer, if desired.

Result: An alarm leads to an orderly response.

What You’ll Achieve

Faster detection and response, complete documentation, no vendor lock-in.

Detect and Respond Faster

Reduced time to detect and contain an incident—through correlation and clear response procedures.

Complete documentation

Searchable logs and audit trails provide the basis for compliance documentation and forensic analysis.

No vendor lock-in

An open stack consisting of Elastic, Wazuh, Graylog, and OpenSearch—full control over data, rules, and costs.

What is your solution built with?

Tried-and-true open-source components—run in-house or via NWS. You decide what you’ll do yourself and what NETWAYS will handle.

Elastic

Search and analysis engine, including Elastic Security: correlation, detection rules, and dashboards—the analytical heart of the SIEM.

Wazuh

Open-source SIEM and XDR for endpoint detection, integrity checks, and compliance checks—threat detection directly on the device.

Graylog

Centralized log management with powerful search and alerting capabilities—ideal for collecting and processing large volumes of logs.

OpenSearch

Open search and analysis platform for logs and events—a license-free alternative that keeps data searchable.

Questions & Answers

Frequently Asked Questions About This Solution

What is a SIEM?

2

3

SIEM stands for Security Information and Event Management. A SIEM centrally collects security-related events and logs from across the entire IT infrastructure, correlates them based on rules, and triggers an alert when suspicious patterns are detected. This makes attacks visible that would otherwise go unnoticed in individual systems.

SIEM vs. SOC – What's the Difference?

2

3

SIEM is the technology that collects and correlates events and generates alerts. A SOC (Security Operations Center) is the team and the process responsible for assessing these alerts and responding to them. NETWAYS sets up the SIEM—and, upon request, also handles SOC-related detection and initial response via MyEngineer.

Which open-source SIEM is good?

2

3

A tried-and-true combination is Wazuh for endpoint detection and compliance, Elastic for correlation and analysis, and Graylog or OpenSearch for log management. Which components are appropriate depends on the sources, scope, and compliance requirements—we provide vendor-neutral recommendations.

How does threat detection work?

2

3

Threat Detection continuously compares incoming events with detection rules and known attack patterns—such as those based on the MITRE ATT&CK framework or Sigma rules. If a pattern is detected or if behavior deviates significantly, an alert is generated, followed by a defined response process.

How much does a SIEM cost?

2

3

That depends on the volume of data, the sources, and the operating model. Because it is open source, there are no per-data-volume licensing fees, as charged by many commercial SIEMs; the costs are primarily associated with setup, infrastructure, and operation. We'll figure that out together based on the scope of your project.

Do I need my own SOC?

2

3

Not necessarily. Having your own SOC is only worthwhile once you reach a certain size. If you don't want to run your own, you can have MyEngineer handle detection and initial response—that way, you get a response comparable to that of a SOC without having to build your own 24/7 team.
