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.

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

"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."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"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 initial setup is pretty straightforward."
"Splunk Enterprise Security has had a positive impact on our organization by allowing us to detect new things with RBA."
"UBA, User Behavior Analytics, is a key feature."
"An example of how these features benefited my organization is that the mean time to detect compromised accounts from the time that we're able to detect that account and then launch some automation to actually disable the account and work with the end user to fix the issue has gone from taking a couple of days to literally taking two to three minutes."
"The site is constantly up, and it's been really easy to adjust the data."
"Splunk has many good apps and has a contribution from all security vendors."
"The metrics and trends that Splunk Enterprise Security generates using all the data points we send allow customers to understand better what their users are doing."
"Splunk Enterprise Security is a valuable tool that allows us to monitor data from the APS daily."
 

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."
"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."
"It would be nice if Splunk reduced the cost of training. Their training sessions are way too costly."
"In the next releases, I would like to see more pricing flexibility."
"To improve Splunk Enterprise Security, I would suggest allowing third-party SOAR solutions to work with it."
"I do not like the pricing model. It is expensive."
"The most significant challenges I face when using Splunk Enterprise Security for advanced threat detection include not having enough time to be in it, the resources and people to also be in there, and trying to configure it and teach people how to use it. A lack of resources prevents us from giving it the attention it needs."
"Splunk is such a large product. Allowing it to be more easily used by people who have not had a lot of training on it would be an improvement."
"I didn't face any major issues with Splunk Enterprise Security. There were only one or two issues related to the user account, but nothing major."
"I encounter issues such as downtime, bugs, glitches, and unbox errors."
 

Pricing and Cost Advice

Information not available
"Splunk Enterprise Security is priced lower than competitors."
"It is not cheap."
"My customers have found the price of the solution to be high."
"My experience with the solution's setup cost, pricing, and licensing was really good."
"Splunk Enterprise Security is expensive."
"It is expensive. I work for multiple clients. I am working for more than five clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel."
"We have seen ROI and improvements as we have continued to use the product, but they are more reactive."
"Truly evaluate the data you want to ingest and go slow. Pulling in data that can provide no use to your mission only wastes data against your license."
