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.

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

"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."
"We have three or four Logstash servers for high availability."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"I can collect logs from various data sources, including hardware."
"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."
"Splunk allows us to customize processing and dashboards, which helps us take care of our customers' needs."
"I haven't had the chance to properly sink my teeth into Enterprise Security but so far I like that they added the MITRE ATT&CK features."
"We can automatically suspend or terminate suspicious sessions."
"This is the right choice if you are looking for a platform that can combine all machine-generated data and use it for various use cases from different domains."
"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."
"The solution's most valuable feature is risk-based alerting, focusing on building out user risks for individuals throughout the enterprise."
"The tool drastically reduces SOC overhead. Its integration with our tool suite is great and helps us correlate events. The solution is also a lot faster than our standalone instances."
"We evaluated several solutions and selected Splunk due to the functionality and cost."
 

Cons

"The product needs to improve its compatibility."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."
"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"Almost all the research can be very bad. We still have a problem with importing the log system."
"The integration feature with other applications, such as anti-DDoS application Arbor, needs to be more powerful."
"In the next release, they should include machine learning-based rules that would streamline the process of finding anomalies."
"The user interface feels clunky to navigate and interact with in Splunk Enterprise Security compared to other case management solutions where it feels easier to use at a high level."
"I think the pricing aspect of Splunk Enterprise Security is quite high compared to other products, which I hear from most of my customers."
"Better education for users would be beneficial as they often don't know what they don't know or how to look for certain features."
"Due to the size limit, we could not see the full product."
"During my experience with Splunk Enterprise Security, I have faced some significant challenges, particularly with customers adapting from version 7 to version 8."
"I would say we haven't seen any return on investment with Splunk Enterprise Security because we are still maturing and trying to get everything situated, and we're experiencing roadblocks with other teams not wanting to give us what we need."
 

Pricing and Cost Advice

Information not available
"Its pricing model can be improved."
"Free Splunk license for PoCs on personal machines and the ability to scale the PoC to an enterprise level app."
"The variables and the flexibility that Splunk provides are helpful, especially in a hybrid and multi-cloud environment."
"Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk."
"The price can always be lower, but it is fair at the moment. The cost efficiencies depend on the licensing and how much data we are bringing in. We have a fairly large footprint, so it is cost-effective."
"Splunk should be able to integrate with other product using the free version."
"While some clients find the cost of Splunk Enterprise Security to be on the higher end, its pricing is comparable to other SIEM solutions."
"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."
