It consolidates all logs into one place and provides required features and functionalities
Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to do RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue.
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.

Quotes from Members

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

Pros

"LogDNA consolidates all logs into one place, which is super valuable."
"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."
"Splunk works based on parsing log files."
"The tool helps with advanced reports and keeps the system scalable and flexible. It provides a clear picture of the current status of any incidents. As a CISO, I see a lot of potential for future innovation, which is interesting. I've noticed better performance, especially with the reports."
"The integration is seamless with many devices and operating systems."
"I like the search feature and the indexing. It's very fast and comprehensive."
"The Splunk user community and forum are most valuable."
"On the cloud, we are pushing through less than half a petabyte of data. So far, it has been fairly stable because it runs on all the underlying AWS infrastructures."
"We used it to create a custom anomaly detection data model to monitor the activity of our back-end services on an hourly basis relative to the past three months of activity."
"They have approximately 50,000 predefined correlation rules, which is quite a lot, and I find that good."
 

Cons

"No ability to encapsulate a query or a filter, and communicate or share that among the team."
"Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue."
"I think the machine learning should be emphasized. Now, it's really important to analyze Big Data, data mining. A SIEM solution, like Splunk, needs an improved data mining solution, artificial intelligence."
"There are new services which are coming up. If Splunk can catch up with the speed of Amazon, and with the integration, instead of us waiting for another year or so, that would be good."
"It takes time to train people."
"Its interface and usability can always be improved."
"They should make data onboarding easier."
"I would like to see more SIEM functionality and a better ticket tool."
"The administration of the cluster and app deployment to indexers or search heads can be done only using ssh access and command line, there is no GUI tools for that."
"At Splunk .conf24, I saw a demo for Splunk Enterprise Security 8. All the things that they have done in Splunk Enterprise Security 8 are what it can be better at."
 

Pricing and Cost Advice

Information not available
"While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."
"Licensing is a yearly, one-time cost."
"Splunk Enterprise Security is expensive."
"It's a yearly subscription."
"The tool's pricing model is great. You can choose between workloads or volume."
"I remember Splunk being relatively affordable. Kibana was more reasonable, but you get more with Splunk. If I was suggesting something, I would probably suggest Splunk because it is better to pay a little bit more and get a lot more."
"While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
"Splunk is definitely not a cheap solution. It is an expensive product."
