Trellix Helix enhanced security, reduced costs, increased efficiency, minimized manual work, decreased downtime, and offered deeper security insights.

I have noticed a return on investment with Splunk Enterprise Security, as it delivers substantial value for money.
Customers see the value in investing in this solution, particularly when it helps resolve issues quickly, turning a potential 20-hour response into one hour.
 

Customer Service

Sentiment score
5.7
OpenText Enterprise Security Manager's service is satisfactory but faces issues with technical support consistency and problem management resolution.
Sentiment score
6.6
Splunk Enterprise Security support is praised for its knowledge, but concerns exist about response times and initial contact expertise.
Sentiment score
6.8
Trellix Helix Connect's customer service is praised for quick, efficient support despite minor delays, maintaining high user satisfaction.
If I raise a P1 or P0 ticket, the response time is often delayed by four to eight hours.
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.
We experienced some challenges due to the ongoing transformation and fusion of McAfee and FireEye, but we are committed to improving response times.
 

Scalability Issues

Sentiment score
7.1
OpenText Enterprise Security Manager offers strong scalability but is costly, requiring expertise and careful budgeting for extensive deployments.
Sentiment score
7.6
Splunk Enterprise Security excels in scalability; however, costs and infrastructure needs can impact on-premise and cloud deployments.
Sentiment score
7.8
Trellix Helix Connect is scalable and favored by many, despite some considering cost as a limiting factor.
It lacks some capabilities compared to other tools available in the market.
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.
We support the largest companies in the world and can cater to large environments.
 

Stability Issues

Sentiment score
7.1
OpenText Enterprise Security Manager is reliable but depends on proper setup; issues are rare when optimized correctly.
Sentiment score
7.8
Splunk Enterprise Security is stable and reliable, requiring careful capacity planning and monitoring for optimal performance.
Sentiment score
8.4
Trellix Helix Connect is highly reliable with strong stability, minimal bugs, and crucial support for critical applications.
The stability of ArcSight Enterprise Security Manager (ESM) is not very robust.
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.
The availability is high, which is critical for our customers who rely on a single panel of glass to operate.
 

Room For Improvement

OpenText Enterprise Security Manager needs UI upgrades, performance improvements, better integration, support, deployment, analytics, and scalability enhancements.
Splunk Enterprise Security requires better user guidance, intuitive tools, AI improvements, affordable pricing, and enhanced performance and integration.
Trellix Helix Connect requires enhancements in interface, integration, support, and pricing, despite praise for its AI capabilities.
The integration aspect of ArcSight Enterprise Security Manager (ESM) needs improvement.
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.
We have just released the solutions to the market recently, making it a revolution in the cybersecurity sector.
 

Setup Cost

OpenText Enterprise Security Manager pricing, while high, is justified by its robust features and deemed competitive for enterprise needs.
Splunk Enterprise Security can be costly due to data volumes, but offers extensive features and potential ROI for enterprises.
Trellix Helix Connect is costly but valued for comprehensive security, especially for large enterprises and bundled solutions.
ArcSight Enterprise Security Manager (ESM) is very cheap compared to other tools.
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.
It is not the cheapest, but also not the most expensive solution.

OpenText Enterprise Security Manager offers powerful integration, real-time threat detection, customization, and robust event management for security teams.
Splunk Enterprise Security excels in log management, swift searches, scalability, user-friendly interface, integration, and compliance, mitigating risks efficiently.
Trellix Helix Connect offers seamless API integration, automation, and AI for efficient threat detection and incident resolution.
The ability to interpret data is highly valued.
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.

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.
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.
BiswabhanuPanda - PeerSpot reviewer
You can use it for everything, incident response, automated responses, alerts, visibility
I would give the product an overall rating of eight out of 10. We have 10 people currently using this software. Six are on the list, plus two managers and two IR experts. It's not possible for just one person to maintain the solution, and it's not really allowed. It has to be a team effort, with two or three people. It's not about users. Helix works differently, collecting logs from 6,000 different sources integrated with the solution. The licensing is not based on users; it's based on APIs. It's more of a SIEM SGL type of platform. It collects logs from around 6,000. But have around 10 people maintaining that.
