Splunk Enterprise Security and Trellix ESM both compete in the SIEM category, with Splunk having the upper hand due to its advanced features and broader integration capabilities.
Features: Splunk Enterprise Security offers rich customization options, scalability, and seamless integration with diverse data sources. It also provides advanced machine learning and rapid data querying. Trellix ESM is cost-effective and user-friendly for smaller environments, with robust log management and basic SIEM features making it ideal for companies with straightforward monitoring needs.
Room for Improvement: Splunk Enterprise Security faces criticism for its high cost, complex pricing, and steep learning curve. Enhancements in UI, deployment complexity, and search functionalities are desired. Improved integration and visualization options are also sought. Trellix ESM needs better integration with SaaS solutions and a clearer UI. Alert customization and case management capabilities could be enhanced.
Ease of Deployment and Customer Service: Splunk offers flexible deployment options including on-premises and various cloud environments but requires skilled resources for setup. Customer service varies, with inconsistent expertise reported. Trellix ESM offers easier deployment and is more favorable in cost for straightforward setups. Its customer service is generally well-regarded, though improvements in resolving complex issues are needed.
Pricing and ROI: Splunk's pricing reflects its extensive feature set, which can be expensive for some businesses. Its ROI is realized through enhanced data insights in large ecosystems. Trellix ESM offers a competitive price point suitable for smaller businesses, delivering value through efficient log management and security monitoring at a lower cost, though its ROI may not match Splunk in advanced analytics environments.
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.
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.
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.
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.
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.
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.
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.
