PRANIL CHANDARKAR - PeerSpot reviewer
Open-source accessibility and ease of implementation empower adaptable log management
As both a customer and an integrator, I think the best features in Logstash are that people prefer it because it is open to all, as it is an open-source version. The functionality of Logstash is quite easy to implement. I can say that the plugin ecosystem of Logstash is great. I have used some plugins for shell script monitoring and for SQL monitoring, and these are all working well with Logstash. The real-time processing capabilities of Logstash are also pretty fine with the tool. When I use the community edition, I have to do many things manually. If I am using enterprise Elastic, then that is taken care of by the Elastic native machine learning.
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

"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"Everything aligns well with improving our organization."
"We have three or four Logstash servers for high availability."
"The transformation means we ship the logs in the way that we want them to be presented in Kibana, which is the main function we use Logstash for."
"I can collect logs from various data sources, including hardware."
"Splunk is quite flexible for our customers. Splunk does not filter from a specific lock, you can define it later."
"The product is good, it satisfies our customers."
"I like Splunk's automated threat detection and orchestration capabilities. Splunk offers a single solution for analyzing, aggregating, correlating, monitoring, reporting, visualizing, etc. You can get all of these capabilities in one place. On top of that, it provides a cloud, testing, on-premise, and hybrid solution, giving customers more flexibility for their use cases."
"Splunk Enterprise Security helped improve our organization’s ability to ingest and normalize data."
"It has virtual visualization, and other products do not."
"Easy to deploy and simple to use."
"Aggregation searches have reduced time and difficulty of identifying trends and conditions which need to reviewed."
"The Splunk user community and forum are most valuable."
 

Cons

"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"The product needs to improve its compatibility."
"We still have a problem with importing the log system."
"Almost all the research can be very bad. We still have a problem with importing the log system."
"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
"We'd like Splunk to reduce false positives."
"Deployment is not difficult but the lock sources and configurations can take time."
"Make it easier to include roles and user controls, as it is horrible now."
"It would be great if I could have a certain dialogue box in Splunk that uses innovative AI tools like ChatGPT, which are available now in the tech department."
"The documentation and training resources available for knowledge and training can be expanded. We need to learn more about Splunk Enterprise Security and new security attacks."
"This is a costly solution."
"If you have to do your own stuff, such as customized charts, it is a little bit more work, but once you're familiar with the Splunk query language, you can pretty much do whatever you want. In terms of features, it should probably have the features that other competitors provide."
"More control with Splunk Cloud as it seems a bit limited. I used to manage an on-premise instance of Splunk Enterprise and really liked having more control over it."
 

Pricing and Cost Advice

Information not available
"The price is comparable."
"It's a yearly subscription."

"Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors."
"The licensing is good, but the pricing absolutely needs some work. It is very high."
"The licensing model can be expensive, but the value it provides is significant."
"Splunk Enterprise Security is affordable."
