Centralized monitoring improves security posture through rapid data processing
The processing part of Elastic Security ( /products/elastic-security-reviews ) 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.
