The documentation is good and provides clear instructions, though it's targeted at those with technical backgrounds.

Sentiment score
6.6
Wazuh offers adaptable scaling, effective for most, despite challenges, excelling in compliance and endpoint management with varied scalability scores.
It lacks some capabilities compared to other tools available in the market.
It can accommodate thousands of endpoints on one instance, and multiple instances can run for different clients.
Currently, I don't see any limitations in terms of scalability as Wazuh can still connect many endpoints.
Scalability depends on the configuration and the infrastructure resources like compute and memory we allocate.

The stability of Wazuh is largely dependent on maintenance.
The stability of Wazuh is strong, with no issues stemming from the solution itself.
 

Room For Improvement

Wazuh requires enhanced interface usability, scalability, AI integration, and easier deployment, with improved reporting and native system integration.
The integration aspect of ArcSight Enterprise Security Manager (ESM) needs improvement.
Machine learning is needed along with understanding user behavior and behavioral patterns.
I think Wazuh should improve by introducing AI functionalities, as it would be beneficial to see AI incorporated in the threat hunting and detection functionalities.
Wazuh could improve by creating videos on YouTube covering installation, use cases, and integration of third-party APIs for different scenarios that other SAAS services provide.
 

Setup Cost

OpenText Enterprise Security Manager is costly but offers robust features and scalability, with possible discounts and cost management strategies.
Wazuh is cost-effective for enterprises with open-source availability but incurs costs for infrastructure, support, and managed hosting.
ArcSight Enterprise Security Manager (ESM) is very cheap compared to other tools.
Wazuh is completely free of charge.
I would definitely recommend Wazuh, especially considering Fortinet's licensing model which is confusing and overpriced in my opinion.
Wazuh is free to use, but there are licensing fees for third parties.

Featured Reviews

Ramnesh  Dubey - PeerSpot reviewer
Allows for monitoring logs according to industry standards within ESM but has a total capacity capped at 12 TB, limiting real-time data retention periods
The first limitation is with the ArcSight Data Storage Manager (ADSM). ArcSight's total capacity is currently capped at 12 TB. This becomes an issue if a customer needs a longer real-time data retention period, such as exceeding 90 days or reaching a year or even ten months. Increasing the disk space beyond 12 TB is not currently possible. So, increasing the storage capacity is one area for improvement. Additionally, the real-time data retention is limited due to the 12 TB restriction. Depending on the Events Per Second (EPS) you receive, you might only be able to retain data for seven to ten days. Overall, the 12 TB limit is the main issue we face in terms of maximizing real-time data storage. Moreover, there are a few improvements I would like to see in future releases. My main suggestion for ArcSight is to simplify the deployment process. Currently, the installation process is quite complex. There are various components involved, including transformations, multiple installations, and containerization for various components. Ideally, I'd recommend that ArcSight allow the entire installation, including the ESM and database, to be completed within a single unified setup process for a streamlined experience. Additionally, having readily available and well-organized documentation for the step-by-step installation process would be incredibly helpful. I would also like to see better support.
Ebenezer Okoh - PeerSpot reviewer
Innovative platform enables proactive threat hunting and endpoint monitoring
I have not seen Wazuh moving in the direction of AI-driven threat detection projects myself, but since the market is moving that way, I wouldn't be surprised if they implemented it soon. My plans to increase the usage of Wazuh or switch to another tool depend on what my boss decides. We don't refer to any community support specifically, as we rely on other platforms such as GitHub or Discord, depending on the application. I recommend that as more companies come on board with Wazuh, it will motivate those who contribute to it, but I am also cautious that as it gains attention, a large company might buy it and change its course of business. Overall, I rate Wazuh a nine out of ten.
