It is very stable.
 

Room For Improvement

Amazon CloudWatch users seek better integration, real-time monitoring, intuitive interfaces, and scalable solutions amid concerns over pricing and log issues.
Splunk Enterprise Security needs improved setup, GUI, user control, pricing, machine learning, and intuitive dashboards for better accessibility.
Maybe Amazon Web Services can improve by providing a library for CloudWatch with some useful features.

Splunk Enterprise Security would benefit from a more robust rule engine to reduce false positives.
What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel.

Rasanpreet Singh - PeerSpot reviewer
Reliable AWS monitoring and logging
The choice of logging solution should always be determined by the specific business requirements. It is crucial to align the logging strategy with what type of logs are needed and how they should be used. There are instances where we require custom solutions to retrieve logs, especially application logs that may not be easily accessible through CloudWatch or similar services. When we heavily rely on AWS native services, CloudWatch is indeed a robust choice. However, in certain scenarios, we might need integration capabilities with other tools, and if they can incorporate such features, it would enhance overall logging capabilities. I would rate it eight out of ten.
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.
