Wazuh vs AlienVault? Which is better for you?
In today’s cybersecurity landscape, Security Information and Event Management (SIEM) tools are no longer optional — they’re essential.
Businesses face an ever-growing range of threats, from ransomware attacks to insider misuse, and they need centralized systems to collect, analyze, and respond to security events in real time.
Two major players in this space are Wazuh and AlienVault (now AT&T Cybersecurity).
Wazuh is an open-source security platform that evolved from OSSEC and offers a wide array of features including log analysis, intrusion detection, vulnerability detection, and cloud security monitoring.
AlienVault USM (Unified Security Management), now part of AT&T Cybersecurity, provides a commercial, all-in-one security solution combining SIEM, asset discovery, vulnerability assessment, intrusion detection, and behavioral monitoring.
The purpose of this post is to give you a detailed Wazuh vs AlienVault comparison, helping security teams, IT managers, and buyers understand the strengths, weaknesses, and ideal use cases of each platform so they can make an informed decision.
To deepen your understanding, you might also explore helpful resources like AT&T Cybersecurity’s official site, the Wazuh documentation.

Let’s dive in and break down what makes each of these platforms unique.
What is Wazuh?
Wazuh is a powerful open-source SIEM and XDR platform designed to provide unified security monitoring and threat detection across hybrid environments.
Originally forked from OSSEC, Wazuh has matured into a robust security solution used by enterprises, government agencies, and educational institutions worldwide.
At its core, Wazuh focuses on host-based security by collecting and analyzing logs, monitoring system behavior, and detecting vulnerabilities and anomalies.
It excels in environments that prioritize visibility, flexibility, and control, especially when organizations prefer a self-managed solution without vendor lock-in.
Key Features of Wazuh:
Host-based Intrusion Detection (HIDS): Monitors system behavior and file changes to detect intrusions at the endpoint level.
File Integrity Monitoring (FIM): Tracks unauthorized changes to critical system files and directories.
Log Data Analysis & Correlation: Collects logs from multiple sources and applies rules to detect suspicious behavior.
Vulnerability Detection: Scans endpoints for outdated software and known vulnerabilities.
Compliance Monitoring: Helps meet regulatory requirements such as PCI DSS, HIPAA, and GDPR.
Integration with the Elastic Stack: Pairs seamlessly with Elasticsearch and Kibana to deliver real-time dashboards and visualizations.
Wazuh is particularly popular among teams that value:
Open-source transparency
Full control over their security stack
Cost-effective scalability
Customizability through rule tuning and scripting
It’s a great fit for organizations with Linux expertise, DevSecOps workflows, or those already using the Elastic Stack for observability — which makes it highly compatible with setups discussed in our posts like Zeek vs Suricata and PRTG vs LibreNMS.
In the next section, we’ll take a closer look at how AlienVault compares as a commercial alternative.
What is AlienVault (AT&T Cybersecurity)?
AlienVault, now known as AT&T Cybersecurity, is a commercial security platform that combines SIEM, threat intelligence, and Unified Security Management (USM) into a streamlined solution designed for businesses of all sizes.
It offers both cloud-based (USM Anywhere) and on-premises (USM Appliance) options, making it flexible for organizations with diverse deployment needs.
Unlike open-source solutions like Wazuh, AlienVault emphasizes ease of use, rapid deployment, and built-in integrations — helping organizations quickly establish a comprehensive security monitoring posture without needing deep in-house expertise.
Key Features of AlienVault:
Built-in Threat Intelligence: Access to continuously updated threat intelligence from AlienVault Labs, including indicators of compromise (IOCs), correlation directives, and response templates.
Asset Discovery & Inventory: Automatically identifies and inventories assets across networks, providing visibility into what needs protection.
Vulnerability Scanning & Behavioral Monitoring: Proactively detects vulnerabilities and monitors network and endpoint behavior for anomalies.
Compliance Management Tools: Offers pre-built reporting and controls to help meet regulatory requirements like PCI DSS, HIPAA, and ISO 27001.
Seamless Integrations: Works well with cloud services, network infrastructure, and third-party tools for centralized security management.
AlienVault is often preferred by:
Small to midsize enterprises (SMEs) seeking an all-in-one, out-of-the-box security solution.
Organizations with limited in-house security staff.
Companies prioritizing turnkey deployment with ongoing vendor support and regular threat intelligence updates.
In contrast to Wazuh’s open-source, self-managed approach, AlienVault delivers a commercial, supported platform that reduces the operational burden on security teams — a point we also touched on in our Wazuh vs Suricata and Zeek vs Suricata posts.
Next, we’ll place Wazuh and AlienVault side by side in a feature comparison table to highlight their core differences.
Wazuh vs AlienVault: Feature Comparison

Wazuh vs AlienVault: Pricing and Licensing
Wazuh
Firstly, Wazuh follows an open-source model, meaning there is no licensing fee for using the platform.
Organizations can download, deploy, and manage Wazuh entirely on their own, making it highly attractive for teams with in-house expertise and limited budgets.
However, large enterprises or teams seeking service-level agreements (SLAs), priority support, and access to enhanced updates can opt for Wazuh’s optional enterprise support packages.
These are offered through the official Wazuh team or certified partners and typically include helpdesk access, expert consultation, and faster troubleshooting.
Costs with Wazuh usually come from:
Internal infrastructure (hardware, cloud hosting, storage)
Staffing and operational overhead for deployment, tuning, and maintenance
AlienVault (AT&T Cybersecurity)
AlienVault operates under a commercial subscription-based model, with pricing usually determined by the number of monitored assets or events per second (EPS).
This subscription covers:
– Access to the software (cloud or on-premises)
– Regular updates and patches
– Access to AlienVault Labs Threat Intelligence (continuously updated rules and signatures)
– Commercial technical support and customer success services
While AlienVault’s pricing is higher than Wazuh’s free model, it offers a turnkey solution that reduces the need for internal security engineering effort.
This makes it popular among organizations that prioritize fast deployment and want to avoid the operational burden of managing an open-source stack.
