We have paid for Splunk support, and we’re not on the free tier hoping for assistance; we are a significant customer and invest a lot in this service.
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.
 

Scalability Issues

Sentiment score
7.3
Elastic Security scales effectively across business sizes, though infrastructure, licensing, and resource management adjustments may be necessary.
Sentiment score
6.4
Fortinet FortiAnalyzer is considered scalable, highly rated in virtual environments, but costs and hardware can limit expansion.
Sentiment score
7.5
Splunk Enterprise Security offers scalable, flexible solutions handling large data volumes effortlessly, though cost concerns persist, especially on-premise.
It allows us to think about specific use cases, such as gathering malicious IPs in a single view and analyzing threats based on geolocation.

Elastic Security is stable and reliable, but big data challenges require proper configuration for optimal performance and care during upgrades.
Sentiment score
7.4
Fortinet FortiAnalyzer is highly stable, with strong user ratings, improved performance, and rare connectivity or resource issues.

7.6
Splunk Enterprise Security is stable and resilient, though resource-heavy queries can cause occasional bugs, needing optimized use cases.
In terms of stability, I would rate Elastic a solid eight out of ten.
We faced some CPU consumption issues, which caused the machine to slow down and required a restart of FortiAnalyzer.
It remains stable during implementation for one or two years.
It provides a reliable solution for managing network-wide data.
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.
 

Room For Improvement

Users seek better authentication, automation, machine learning, intuitive design, scalability, integration, training resources, and pricing transparency in Elastic Security.
Fortinet FortiAnalyzer needs UI improvements, better integration, enhanced analytics, and competitive pricing for multi-vendor compatibility and ease of use.
Splunk Enterprise Security users desire improved GUI, integration, pricing, training, data handling, and advanced features for better efficiency.
CrowdStrike and Defender have more established threat intelligence integration due to having a larger client base.
My security testing team continuously reports vulnerabilities, and we have to fix and update the versions frequently.
Elastic Security consumes a lot of resources, requiring a substantial deployment setup.
When licensing, each device is licensed separately, such as the firewall, which can become expensive.
This would help in analyzing various security incidents and events more effectively by delivering a handful of relevant logs instead of thousands.
Enhanced deep inspection features would make troubleshooting easier.
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.
 

Setup Cost

Elastic Security offers a competitive pricing model with a free core version, suitable for small to medium enterprises.
Fortinet FortiAnalyzer's pricing is competitive but high, with subscription-based licensing that may be costly for smaller businesses.
Splunk Enterprise Security is costly but valued for features and scalability, with pricing concerns for smaller businesses.
The pricing is reasonable, especially for Small Medium Enterprises (SMEs), making it a viable option for businesses building their security infrastructure.
This is beneficial for SMEs as they do not need extensive budgets for security solutions.
Elastic Security is considered cost-effective, especially at lower EPS levels.
Its licensing model is based on the amount of log data processed per day, making it more cost-effective compared to QRadar, which is EPS and device-based.
In terms of pricing, FortiAnalyzer is not expensive.
In the Indian market, Fortinet's pricing is very competitive, allowing us to win most of our deals.
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.
I find it to be affordable, which is why every industry uses it.

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.

Centralized monitoring improves security posture through rapid data processing
The processing part of Elastic Security is very interesting for us since we handle almost 7,000 to 8,000 alerts per minute. We require rapid processing speed for alerts and event data, and Elastic Security is very efficient at handling this level of data. Additionally, Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing.
Manikandan Kannan - PeerSpot reviewer
Simplifying log management by displaying detailed access information
The most valuable feature of Fortinet FortiAnalyzer is its ability to simplify and display logs clearly, providing details like which IPs are accessing the system, the destination, and the policies applied. This visualization and detail make managing logs more straightforward. In conjunction with our VMware setup, Fortinet FortiAnalyzer enhances organizational efficiency, meeting the standard log retention period for up to a year.
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.
