Sentiment score
4.1
VMware Aria Operations for Logs users experience mixed support quality, with slow but effective escalation to skilled experts.
The technical support is good; we have a separate portal for partners, and since we are paying for the service, they provide a response timeframe based on severity—critical issues are addressed within four hours, medium issues within one day, and non-urgent issues may take a couple of days.
Customer support is very helpful and effectively solves my problems.
If you want to write your own correlation rules, it is very difficult to do, and you need Splunk's support to write new correlation rules for the SIEM tool.
They try to close issues as soon as possible, often just offering documentation links.
They are responsive and effectively resolve issues.
While support staff is knowledgeable, getting access to specialists can be challenging when dealing with the limits of a product.
Customer service and support have declined.
I did not need technical support because I am a professional with VMware.

LogRhythm SIEM is highly scalable as it has modular components allowing me to expand storage, indexing, or other resources as needed.
LogRhythm SIEM is scalable; it can handle about 200 or 500 devices without much difference.
They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.
It is easy to scale.
It's big in a Central European context, and small from a Splunk North American context.
Since payment is based on hardware, scalability impacts are managed more effectively than with other tools paid by data volume.
It's relatively easy to find individuals with the skills to work with VMware because it is a widely spread tool.

Splunk Enterprise Security is stable and reliable, though performance challenges occur with high data volumes and complex queries.
Sentiment score
7.1
VMware Aria Operations for Logs is stable, integrates with Microsoft, and is reliable, with minor issues resolved swiftly.
The platform needs regular updates to fix problems encountered with each quarterly patch and version release.
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
I would rate it a ten out of ten for stability.
Managing a lot of data involves reliance on hardware and network performance, which are external factors that can affect stability.
It has been very stable, and every time I needed it, it was available and working.
VMware as a whole provides very stable tools.
 

Room For Improvement

LogRhythm SIEM needs better integration, UI improvements, enhanced reports, and Linux-based support for efficiency and tool integration.
Splunk Enterprise Security needs interface and integration improvements, streamlined setup, better training, cost adjustments, and enhanced AI features.
VMware Aria Operations for Logs needs better usability, integration, documentation, cost efficiency, stability, and enhanced filtering and dashboard features.
I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.
A more user-friendly user interface with drag-and-drop features, similar to key competitors like Splunk, would be beneficial.
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
Splunk Enterprise Security is not something that automatically picks things; you have to set up use cases, update data models, and link the right use cases to the right data models for those detections to happen.
For any future enhancements or features, such as MLTK and SOAR platform integration, we need more visibility, training, and certification for the skilled professionals who are working.
It would be beneficial to have a roadmap for these dashboards to ensure consistent functionality.
There is also dissatisfaction with Broadcom's broader attitude, which is prompting me to search for alternatives.
VMware Aria Operations for Logs is not a cost-effective tool.
 

Setup Cost

LogRhythm SIEM offers competitive pricing with comprehensive features, though scalability and additional features may increase costs.
Splunk Enterprise Security, seen as costly, offers extensive features, requiring careful data management to optimize expenses.
VMware Aria Operations for Logs is cost-effective within bundles but pricey without, leading to mixed enterprise buyer opinions.
The license cost is around $10 per MPS.
I find LogRhythm SIEM affordable, as it is a bit less costly than QRadar.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.
Splunk is priced higher than other solutions.
Splunk, often paid by the terabytes, becomes expensive quickly if not managed carefully.
The price has risen significantly, and for smaller customers, the cost can be up to ten times more than before.
VMware comes with a lot of packages, however, it remains too expensive.
 

Valuable Features

LogRhythm SIEM excels in threat detection, user-friendly interface, and integration, offering centralized logs and customizable alerts.
Splunk Enterprise Security offers powerful data management, flexible search, seamless integration, and advanced threat detection tools for efficiency.
VMware Aria Operations for Logs optimizes infrastructure with dashboards, real-time notifications, and scalability, enhancing troubleshooting and cost efficiency.
The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient.
We have enough budget for cloud deployment, but we choose to keep it on-prem to ensure data privacy; cyberattacks are a concern, but data privacy is the foremost priority due to sensitive government information.
This capability is useful for performance monitoring and issue identification.
I assess Splunk Enterprise Security's insider threat detection capabilities for helping to find unknown threats and anomalous user behavior as great.
Splunk Enterprise Security provides the foundation for unified threat detection, investigation, and response, enabling fast identification of critical issues.
This tool also provides greater insight when integrated with VMware infrastructure, making it more precise than other tools.
The most valuable features are log centralization and long-term retention for logs.
A valuable feature of VMware Aria Operations for Logs is its ability to allow personalization of dashboards and requests.

Featured Reviews

Mokhammad Rakhman - PeerSpot reviewer
User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.
LarsChristensen - PeerSpot reviewer
Efficient troubleshooting with precise log filtering and an easy setup
The tool could benefit from improved filter settings and dashboarding. While there are dashboards available, they are often created by community members and may not work after updates. It would be beneficial to have a roadmap for these dashboards to ensure consistent functionality. It would also be advantageous if the tool could process even large amounts of data faster, though this may be more related to data movement challenges rather than the software itself.
