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.

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."
"I can collect logs from various data sources, including hardware."
"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."
"Everything aligns well with improving our organization."
"We have three or four Logstash servers for high availability."
"The ability to ingest different log types from many different products in our environment is most valuable."
"Splunk Enterprise Security is fast and well-documented, and user interface and user interaction are well-designed compared to other SIEM solutions."
"The most useful feature for me is the ability to create different kinds of alerts and set a different kind of denominator that will capture the real event. That is helpful for a power user like me."
"The solution's most valuable features are its ability to transact in the cloud and its ability to onboard data easily with minimum connectors."
"This solution is the best security solution."
"The most valuable feature is the DSS, also known as SPL, because it allows users to script advanced queries with limited knowledge."
"The features of Splunk Enterprise Security that I prefer most are the correlation engine and the common information model, basically the aggregation of data."
"The integration and plugin availability are nice, and the AI module is also great."
 

Cons

"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."
"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"Sometimes, there is latency in the logs."
"Because the licensing model is very complicated to understand, it would be better to start with another product that provides a better licensing model."
"It can be tough to get a hold of somebody in technical support depending on the complexity of the issue."
"Search head clustering is often temperamental in its current state and should be improved, replaced by something better, or be reverted to search head pooling."
"The GUI can be improved. Splunk has always suffered from having a kind of goofy UI, it needs some updating."
"There is another new term called benign positives. It is better to clearly identify each definition of those terms since it has not been popular in the industry, and everyone needs to be aware of those things."
"One of the improvement points that Enterprise Security could offer is on-prem training, the availability to have a Splunk representative come out to different sites and actually sit down with the organizations and help them understand."
"The solution is expensive."
 

Pricing and Cost Advice

Information not available
"Splunk Enterprise Security is affordable."
"Splunk should be able to integrate with other product using the free version."
"Splunk Enterprise Security is an expensive solution."
"The cost is on the high end, which makes it difficult for some organizations to use."
"Splunk Enterprise Security's pricing is pretty competitive."
"Splunk can be expensive, as its licensing is based on the daily data ingestion volume."
"It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."
"The Splunk Enterprise Security license is expensive."
