Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.2
Splunk Enterprise Security boosts efficiency and ROI with enhanced insights and automation, despite potential cost concerns.
Sentiment score
5.4
McAfee's ROI is praised for security management, despite executives seeking better ESM report visibility at the C-level.
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.
Splunk's cost is justified for large environments with extensive assets.
 

Customer Service

Sentiment score
6.7
Splunk Enterprise Security support is generally positive, but response times vary, and complex issues may require escalation.
Sentiment score
5.9
Trellix ESM's customer service is praised, but technical support quality is inconsistent and varies by region, needing improvement.
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.
I would rate support for Trellix ESM 10 out of 10 because if we connect with the support in the UK, we get excellent support.
 

Scalability Issues

Sentiment score
7.7
Splunk Enterprise Security excels in scalable performance, adaptable across environments, though scaling can increase costs.
Sentiment score
8.5
Trellix ESM is adaptable and scalable, suiting diverse business sizes and needs, though setup may challenge smaller users.
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.
Scalability is quite easier with Trellix ESM, because all we need to do is add more receivers to it, so it can go to any point.
 

Stability Issues

Sentiment score
7.9
Splunk Enterprise Security is praised for its stability and performance, though updates and heavy usage can cause minor issues.
Sentiment score
8.5
Trellix ESM is perceived as stable overall, with occasional bugs resolvable by support, especially stable in data centers.
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.
It is very stable.
 

Room For Improvement

Splunk Enterprise Security struggles with UI complexity, costly licenses, integration challenges, setup complications, and limited customization and AI features.
Trellix ESM needs improved stability, a modern interface, better integration, decreased resource use, and enhanced analytics capabilities.
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.
What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel.
If there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that.
 

Setup Cost

Splunk Enterprise Security is costly for smaller businesses, with pricing challenges based on data volume impacting budget considerations.
Trellix ESM offers competitive and flexible pricing, with discounts for large purchases, easy deployment, and annual or monthly payments.
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.
 

Valuable Features

Splunk Enterprise Security offers robust search, effective integration, and adaptability for enhanced visibility and threat management in diverse environments.
Trellix ESM offers user-friendly features like dashboards, integration, threat monitoring, and automation for enhanced security and operational efficiency.
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.
They have approximately 50,000 predefined correlation rules.
The weakest point is it doesn't cover almost all the devices, so the customer has to be more dependent on the parsers to be written by the Professional Services team.

Featured Reviews

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.
Daniel Durian - PeerSpot reviewer
Helps to monitor and detect cyberattacks
The tool's effectiveness depends on how you define your log sources. To build visibility of incoming and outgoing traffic, you need logs from perimeter defense, firewalls, web application firewalls, and endpoint protection. With good traffic visibility, incident response time is really quick. Trellix ESM provides situation awareness. On the dashboard, I can see outbound and inbound communications to known threat hosts, IPS/IDS activity, and threat intelligence of the perimeter defense in the firewall. This information helps preempt attacks.
