Featured Reviews

Mohammed-Abdelalim - PeerSpot reviewer
Assistant Vice President at QualityKiosk Technologies Pvt. Ltd.
Exploring resilience and integration capabilities while navigating complexity and technical challenges
Logstash lacks a graphical user interface, necessitating a strong programming background to handle it effectively. It is challenging for business users who need a skilled team for its operation. Changing pipelines is not easy because Logstash requires pipelines to be programmed and cannot just be dragged and dropped like other data solutions. Additionally, Logstash does not automatically make actions based on the data it receives; integrating automation tools is required.
Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
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."
"We have three or four Logstash servers for high availability."
"Everything aligns well with improving our organization."
"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."
"I can collect logs from various data sources, including hardware."
"The search function for splunk is like a google search. You just enter and it will quickly show you the results."
"Splunk Enterprise Security has had a positive impact on our organization by allowing us to detect new things with RBA."
"Splunk is our monitoring and investigating Swiss Army knife for key applications and systems."
"Correlation search, in general, is valuable because it allows us to search multiple data sources easily."
"Splunk is good at log collection and log management."
"The risk-based alerting (RBA) is one of the valuable features."
"It saves us a lot of time, just in man-hours, and being able to look at hundreds or thousands of servers simultaneously."
"The detailed log view is easy to read."
 

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."
"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."
"Almost all the research can be very bad. We still have a problem with importing the log system."
"Operational workflow, use case framework, and ticketing systems need improvement to make it suitable for SOC environments."
"The algorithms customization of Splunk could improve. They have limited algorithms for machine learning support. If they can allow the user to add more machine learning algorithms, such as the ability to choose the algorithm that a user might want. Additionally, they should provide the required libraries for those algorithms, and then analyzes the data for use."
"Previously, they developed custom connectors or add-ons for a lot of applications. But that number can be upgraded still. There are a lot of applications in the world that are not supported."
"A lot of people are averse to using new tools so if they make it even more user-friendly than it already is, I think that could go a long way."
"To improve Splunk Enterprise Security, I would suggest allowing third-party SOAR solutions to work with it."
"Deployment is not difficult but the lock sources and configurations can take time."
"The NLP-based thing will give risk-based alerting which will reduce more than 50%, but I could see only 30%."
"In terms of improvement, the dashboards are not up to the mark. If you compare with Tableau and Power BI reports, they are more customized, more user-friendly, and more interactive."
 

Pricing and Cost Advice

Information not available
"Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk."
"It is possible to use a developer's license, which is up to 10GB per day of volume traffic, which is usually enough for most use cases."
"It's definitely worth it."
"Splunk is expensive based on our current requirements, but it's obviously worth what we pay."
"Splunk licensing model might seem expensive but with all the gain in functionalities you will have compared to traditional SIEM solutions I think it’s worth the price."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
"You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
"The pricing model is expensive and a nightmare based on the amount of data."
