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

"Everything aligns well with improving our organization."
"I can collect logs from various data sources, including hardware."
"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."
"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 benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers."
"Previously, it would take us days to properly analyze, triage, and respond to insider threats; now with risk-based alerting, we are able to reduce that to 10 minutes."
"Being able to track impossible travel logins and things of that nature is valuable. We can track user logins from various IPs, various countries, and at various times to see if everything adds up."
"In terms of technical support, we don't have any issues, as the professional services which they have extended to us are very, very good."
"Splunk's visualizations make it easy for users to understand the data."
"It's very flexible. If you look from the cloud implementation it is there. Reports are made quickly. Unlike other tools, it caters to all kinds of technical information on the front very easily. There's no need to put in any technical information. You can pull on the reports very easily, take action, and notify stakeholders."
"Splunk may be more costly upfront, but in the long run, it saves on time and man-hours."
"Splunk is one of the top SIEM solutions to work with."
 

Cons

"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"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."
"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."
"The system can be intimidating, and sometimes the concepts conveyed in the documentation require adjustment."
"The biggest problem is data compression. Splunk is an outstanding product, but it is a resource hog."
"The area of concern revolves around the fact that Splunk is an expensive product."
"Splunk Enterprise Security is complicated in terms of developing specific cybersecurity use cases."
"Cybersecurity and infrastructure monitoring have room for improvement."
"The main issue that I have with it is that the field transformations sometimes overlap with those in Splunk Enterprise, and then you get permissions issues that lead to troubles."
"My biggest struggle with Splunk in general is memorizing all the commands. If I want to know which users have logged in between certain hours, I cannot write that query out. It would be helpful to have AI so that I can explain in simple terms what I want and then the search gives that back to me. I am waiting for that."
"Index performance is a bit slow but this is partly due to the huge volumes of data for our industry within our environment."
 

Pricing and Cost Advice

Information not available
"It is a bit costly."
"It's a little bit expensive for a small to medium enterprise."
"Licensing is a yearly, one-time cost."
"Some of the insights that we have obtained as a part of using Splunk have greatly helped us in increasing our revenue in terms of selling our products."
"It would be nice if the pricing were cheaper. However, we did purchase it."
"Splunk is priced higher than other solutions."
"Pricing can be a limiting factor. You have to continuously tune what you are bringing in and make sure what you bring in is of value."
"The pricing can be better. We are already considering Elastic because Splunk is too expensive. You have to pay based on per-day ingestion. There should be a more flexible model for the use cases where one day you have a huge amount, and on other days, it is quite less."
