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.

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

"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."
"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."
"We have three or four Logstash servers for high availability."
"The feature I appreciate the most about Splunk Enterprise Security is the CIM data model, which allows users to bring in data from different technologies, such as firewalls, endpoints, and perimeter DMZs, enabling every device to pump data into Splunk Enterprise Security, with the data model normalizing all the data and placing it in a common plane."
"We see a lot of return on investment with Splunk Enterprise Security, as once implemented, it gives us a quick and responsive way of understanding alerts, which stands out compared to other solutions."
"We have been very happy with its capabilities in general."
"It has been really good at consolidating a lot of data from different sources. It's really good at generating summaries."
"Support is quick and competent."
"Over the course of using Splunk Enterprise Security, it has helped us grow our business and attract more clients due to its low mean time to respond and various analytic engines that help us address threats daily, resulting in positive customer feedback and satisfaction."
"The best features I've experienced over the past six years with Splunk Enterprise Security are the ability to create use cases and the flexibility to customize searches and use cases based on our specific requirements."
"With good domain knowledge, one can build almost anything. If you throw in Alert Manager or an integration with ServiceNow. Then, you have your own SIEM"
 

Cons

"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."
"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."
"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."
"It's difficult to set up initially, and their billing model is also a bit complicated."
"The way Splunk Enterprise Security could improve is by pulling in and mapping my DHCP data and tracking users' IP addresses as it changes throughout sessions, and being able to keep track of who is actually assigned to what IP address more natively."
"It is very complicated to write your own correlation rules without the help of Splunk support."
"When files are absent, troubleshooting becomes difficult, and performance issues inevitably arise."
"To improve Splunk Enterprise Security, I would suggest allowing third-party SOAR solutions to work with it."
"The integration with all our tool sets felt like we were reinventing the wheel, which was a pain point for us."
"We'd like to have the number of devices covered under the license to be increased."
"Given the ever-increasing number of threats, I would like Splunk to update its threat signatures more frequently."
 

Pricing and Cost Advice

Information not available
"It is not cheap."
"Expensive compared to other options."
"It is a bit costly."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"Splunk is costly but it’s worth it due to the high-end features."
"Its price is fair. Like with anything else, if you go into the cloud, different providers cost more, and you are able to throttle back or throttle up. The cost is comparable with anything else."
"Splunk Enterprise Security is a worthwhile investment given the comprehensive range of features it offers."
"Splunk Enterprise Security is a bit expensive overall, but it provides good value."
