Customer Service

Sentiment score
5.4
OpenText Enterprise Security Manager support receives mixed reviews, with common complaints about slow resolution and inadequate expertise in complex issues.
Sentiment score

Wazuh support is effective for paid users, but open-source users face variability in community responsiveness and documentation use.

They responded quickly, which was crucial as I was on a time constraint.
There is no dedicated technical support for Wazuh as it is open source.
The documentation is good and provides clear instructions, though it's targeted at those with technical backgrounds.
 

Scalability Issues

Sentiment score
5.9
OpenText Enterprise Security Manager is scalable for large deployments but faces cost challenges at the logger level.
Sentiment score
7.5
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.
 

Stability Issues

5.1
OpenText Enterprise Security Manager is stable and reliable, though performance varies with challenges in virtualization and specific components.
Sentiment score
6.6
Wazuh's stability generally ranges from moderate to high, contingent on proper maintenance, updates, and user-specific technical environments.
The stability of ArcSight Enterprise Security Manager (ESM) is not very robust.
The stability of Wazuh is largely dependent on maintenance.
The indexer frequently times out, requiring system restarts.
The stability of Wazuh is strong, with no issues stemming from the solution itself.
 

Room For Improvement

OpenText Enterprise Security Manager needs user interface upgrades, better integration, improved documentation, and enhancements in analytics and scalability.
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.
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.
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.
The integration modules are insufficiently developed, necessitating the creation of custom integration solutions using tools like Logstash and PubSub.
 

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.
Totaling around two lakh Indian rupees per month.
Wazuh is free to use, but there are licensing fees for third parties.

Wazuh offers customizable open-source security solutions with SIEM, MITRE, and compliance tools for cloud-native, Kubernetes, and Azure environments.
The ability to interpret data is highly valued.

With this open source tool, organizations can establish their own customized setup.

Featured Reviews

Gaurav Ranade - PeerSpot reviewer
Excels at performing regression and correlation on the data
ArcSight is a legacy technology, and many customers want AI-powered technologies integrated with it. That hasn't been done yet, but ArcSight needs to catch up with the newer solutions and technologies available in the market. It can't just rely on the legacy technology from 2010 or 2012. You can't run that in 2024. It's a legacy technology with its own limitations. Customers often face issues that other software or newer solutions can resolve easily. That's the main challenge we face from customers right now. So, the only concerns are that AI needs to be integrated and scalability improved. Those are the main areas to be improved.
Sandip_Patel - PeerSpot reviewer
Evaluating robust file monitoring with insights for community support improvements
Wazuh's most valuable features include file monitoring and compliance reporting, which do not require excessive costs. These aspects are vital as they provide alerts for changes and facilitate the monitoring of compliance. The platform is also relatively easy to set up and operate. Reports are straightforward to extract and prove useful for compliance requirements.
