Wazuh SIEM AMI for AWS: production-ready security monitoring without the build-out

Open-source SIEM is attractive for an obvious reason: it avoids per-endpoint licensing that scales painfully with every new server or workstation added to the environment. Wazuh is a credible answer to that problem. It's a real, widely deployed open-source security platform, but it is not a single application. It is a coordinated stack made up of a Manager, Indexer, Dashboard, and Filebeat, and getting those four components installed, versioned correctly, and configured to talk to each other is its own infrastructure project on a bare EC2 instance, often taking longer than security teams budget for before they see any real detection value.

This AMI collapses that build-out into a single launch. It delivers a production-ready Wazuh deployment on Ubuntu 26.04, with every component of the stack preinstalled, interconnected, and ready to start ingesting data from the first boot.

Quick facts

Table 1. At-a-glance specification of the Wazuh SIEM AMI.

What Wazuh actually does

At its core, Wazuh provides centralized log collection and analysis, intrusion detection, file integrity monitoring, vulnerability detection, compliance auditing, and real-time security alerting. It covers Linux, Windows, containers, and cloud infrastructure through lightweight agents that report back to a central manager, giving a single dashboard view across an entire environment instead of siloed logs scattered per system.

Architecture: how the pieces fit together

Table 2. Core Wazuh stack components and what each one is responsible for.

Understanding this layout matters operationally: the Indexer is the component that scales with event volume, it's where capacity planning effort should go, while the Manager is where detection logic and rule tuning live. Treating Wazuh as "one app" instead of this four-part pipeline is the most common reason self-managed installs stall out before going live.

Who this is built for

This fits SOC teams that want to run their own detection stack instead of paying per-endpoint SaaS SIEM pricing, MSSPs that need to stand up a security monitoring stack per client or tenant on demand, and enterprises that need file integrity monitoring, vulnerability tracking, and compliance auditing to happen inside their own AWS account rather than being shipped off to a third-party service.

Connecting agents

Once the manager is live, endpoints across Linux, Windows, and containerized environments each install a lightweight Wazuh agent pointed at the manager's address. From that point on, file integrity events, log data, and vulnerability findings flow into the central dashboard automatically, with no per-agent manual configuration beyond initial enrollment.

Compliance and audit use cases

Beyond day-to-day alerting, Wazuh's file integrity monitoring and vulnerability detection outputs are exactly the kind of evidence auditors typically ask for during compliance reviews. Having that data centralized and continuously collected, rather than assembled manually before an audit, turns compliance reporting into something that's already happening in the background rather than a scramble before an assessment.

Step-by-step: from launch to first alert

1. Launch the AMI from AWS Marketplace at the recommended instance size for expected log volume.
2. Restrict inbound access to the Dashboard and Manager ports to known/admin IP ranges via security groups.
3. Log into the Dashboard and review the default detection rule set.
4. Install the Wazuh agent on a first batch of endpoints, pointing each at the Manager's address.
5. Confirm agent data is arriving in the Dashboard and tune alert thresholds before wider rollout.
6. Define a retention and backup policy for the Indexer before the environment reaches meaningful scale.

How billing works

Pricing is a usage-based subscription at $0.10 per hour, stacked on top of normal AWS EC2 infrastructure costs for the instance size chosen. There's no minimum commitment, and the subscription can be canceled at any time.
