Transforms logs for real-time insights and seamless reporting
Logstash is used for transforming logs, and you can use many plugins in Logstash. Logstash works with configuration files that contain three main parts: an input part, a filter part, and an output part. In the input part, we can take logs from many sources such as Beats, files, or Kafka. The filter part is used to filter the logs that are shipped from Beats. From my understanding and experience with Logstash, it is usually used for processing logic, meaning I can control what fields should be transferred to Elastic and what fields shouldn't be transferred. This is the main function I use Logstash for. Elastic is a famous open-source searching engine that helps operation teams speed up the investigation process and provides real-time insights for performance reporting.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

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."
"I can collect logs from various data sources, including hardware."
"We have three or four Logstash servers for high availability."
"The functionality of Logstash is quite easy to implement and the plugin ecosystem of Logstash is great, with plugins for shell script monitoring and SQL monitoring working well with the tool."
"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."
"The feature I appreciate the most about Splunk Enterprise Security is the dashboard."
"The site is constantly up, and it's been really easy to adjust the data."
"The search function for spam is like a google search. You just enter and it will quickly show you the results."
"The query functionality is very easy to use and fast to retrieve logs in comparison to other SIEM solutions."
"It definitely does help with both auditing and as well as regular monitoring. SOC does more monitoring, but ES also gives you other features that are auditing-related. The dashboards are also beneficial."
"The most valuable feature is the incident dashboard, and the extensive use of correlation searches, which isn't available with a standard Splunk search package. This feature is important to me because it enables SOC analysts to do their job more efficiently and be able to investigate or mediate incidents at a faster pace."
"Splunk has a single purpose in life: ingest machine data and help analyze and visualize that data."
"They provide excellent predefined user cases."
 

Cons

"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."
"The product needs to improve its compatibility."
"Almost all the research can be very bad. We still have a problem with importing the log system."
"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"We still have a problem with importing the log system."
"Splunk can improve regex/asset analysis as we do not want to crawl until it is done."
"The setup time is quite long."
"The access and identity features could be improved. For example, let's say we have onboarded 65 logs. Now, we can identify the various processes, but we run into trouble when we're updating the processes for AWS CloudTrail, EDR, MDR, and XDR."
"Queries are not always as easy or straightforward as they might be, so it can be difficult to figure out what you need to look for."
"The Web Application Firewall will send you too much information because it's more dedicated to security than a normal firewall."
"The TERM licensing model is still not very useful. It's not helping us."
"It's missing some features that other solutions have, such as the ability to upgrade the endpoint and perform endpoint universal forwarders from a deployment server instead of using a third-party solution, such as Puppet or Ansible."
"We do have to educate developers on how to not blow it up. It is a little to easy to write an expensive query and overly stress the system. This could be improved."
 

Pricing and Cost Advice

Information not available
"It is not cheap."
"Splunk can be an expensive solution. It all depends on how we configure the alerts and the events from the endpoints. You can save some money if you do that correctly. If not, it becomes an expensive solution."
"Splunk Enterprise becomes extremely expensive after the 20GB/month license."
"I assume that the pricing is reasonable, because if it was too costly, there are other alternatives."
"While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
"Free Splunk license for PoCs on personal machines and the ability to scale the PoC to an enterprise level app."
"I believe that Splunk Enterprise Security is worth the price, but it is expensive."
"The pricing is based on the volume of data fed into it, which can lead to substantial costs. This pricing model is complex and unpredictable, making cost management difficult."
