Derrick Brockel - PeerSpot reviewer
The solution is a consistent logging platform that provides excellent query mechanisms
We can query a lot of data points and build dashboards. The vendor is good at adjusting their models. Most companies want us to forecast our yearly use and pay it upfront on day one. With Logz.io, we commit to use 14 TB in a year. However, they measure us every month and give us a monthly bill. Depending on our monthly usage, we pay for 14 TB divided by 12 months or a little extra. It's a little bit more like AWS. Other solutions do not do it. They want their money upfront. We really like the dashboards. We have 36 sub-accounts. Each sub-account is an app, and we could put restrictions on that app. Previously, there were capacity restrictions on the sub-accounts. If we have a sub-account of 1 TB and use only 100 GB, we waste 900 GB that day. We could not share it between sub-accounts. Now, they provide an overhead volume. We do a reserve, and any sub-account could use anything over the reserve. It utilizes our footprint better.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We use the product for log collection and monitoring."
"The visualizations in Kibana are the most valuable feature. It's much more convenient to have a visualization of logs. We can see status really clearly and very fast, with just a couple of clicks."
"We use the tool to track the dev and production environment."
"The tool is simple to setup where it is just plug and play. The tool is reliable and we never had any performance issues."
"It is massively useful and great for testing. We can just go, find logs, and attach them easily. It has a very quick lookup. Whereas, before we would have to go, dig around, and find the server that the logs were connected to, then go to the server, download the log, and attach it. Now, we can just go straight to this solution, type in the log ID and server ID, and obtain the information that we want."
"InsightOne is the main reason why we use LogMeIn. This is mostly because of log data that we are pushing tools and logs in general."
"The other nice thing about Logz.io is their team. When it comes to onboarding, their support is incredibly proactive. They bring the brand experience from a customer services perspective because their team is always there to help you refine filters and tweak dashboards. That is really a useful thing to have. Their engagement is really supportive."
"The query mechanism for response codes and application health is valuable."
"Splunk Enterprise Security's dashboards are a key asset."
"The solution's most valuable features are its ability to transact in the cloud and its ability to onboard data easily with minimum connectors."
"The ability to quickly search logs, performance data, and other inputs has helped tremendously with troubleshooting."
"We have found all the features useful. However, the dashboarding and logging have been very helpful. Additionally, the log analysis does a great job."
"We were able to create a catalog of dashboards and have a holistic view at all levels. We could understand our business much better. Real-time errors, which were buried in emails before now, surfaced up on dashboards."
"We evaluated several solutions and selected Splunk due to the functionality and cost."
"I like the ease of setting up dashboards on Splunk. They're easy to create, manage, alter, and share. You can fine-tune them any way you see fit."
"Great platform with user-friendly interface and GUI."
 

Cons

"The solution needs to improve its data retention. It should be greater than seven days. The product needs to improve its documentation as well."
"The solution needs to expand its access control and make it accessible through API."
"The price can be cheaper and they should have better monitoring."
"When it comes to reducing our troubleshooting time, it depends. When there are no bugs in Logz.io, it reduces troubleshooting by 5 to 10 percent. When there are bugs, it increases our troubleshooting time by 200 percent or more."
"I would like them to improve how they manage releases. Some of our integrations integrate specifically with set versions. Logz.io occasionally releases an update that might break that integration. On one occasion, we found out a little bit too late, then we had to roll it back."
"Capacity planning could be a little bit of a struggle."
"I would like granularity on alerting so we can get tentative alerts and major alerts, then break it down between the two."
"The product needs improvement from a filtering perspective."
"I haven't found a way for me to create my own plugins and integrate them into Splunk, but this isn't necessarily a limitation; it could simply be a lack of knowledge on my part."
"Its interface could be improved."
"From the commercial point of view, they have to bring down their costs."
"Splunk could have more built-in use case presets that customers can build on and customize."
"If you have to do your own stuff, such as customized charts, it is a little bit more work, but once you're familiar with the Splunk query language, you can pretty much do whatever you want. In terms of features, it should probably have the features that other competitors provide."
"Although the technical support is adequate, there is still room for improvement."
"Splunk Enterprise Security offers a vast amount of information to learn and comprehend, resulting in a challenging initial learning curve."
"The solution could improve by making it more business analysis oriented. The way it is now is designed more for developers."
 

Pricing and Cost Advice

"The product is a little expensive."
"You pay for what you need, and that is a good model. They are also quite happy to talk to you about your uses and your use case. They will even go as far as suggesting things that you don't need to do in order to save you money. At one point, I was quite surprised at how cheap it could be if we wanted it to be or how much they would help us manage our costs."
"The product's pricing is cheaper than other solutions."
"At the time it was set up, we thought Logz.io was very reasonable for what we were getting in terms of how much time and hosting costs it was saving us, because you don't have to run the servers for it anymore."
"The tool is an open source product."
"The price of this solution is expensive. However, it has great features. If you want a great solution you need to pay a price matching the features."
"It's a little bit expensive for a small to medium enterprise."
"The price is comparable."
"It is pretty straightforward and based on the sizing. If I compare it with other competitors, it makes sense."
"My customers have found the price of the solution to be high."
"From what I have seen so far, Splunk has multiple cost models. The one that we are using is pretty good when it comes to ingesting data into the environment. It has worked out pretty well."
"The pricing of Splunk Enterprise Security is high."
"This product could use better pricing in general."
