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

"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 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 product for log collection and monitoring."
"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."
"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."
"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."
"We are much faster finding and addressing issues with Splunk."
"Splunk gives my clients the ability to bring multiple, disparate types of data together, then correlate and report on them."
"The most valuable function is the notable events. When I joined the team, I asked them what they could currently see, and they said nothing. I was pretty shocked. I know for a fact that they're using Enterprise Security or at least they had purchased it. I told them that there are several dashboards within Splunk that we can leverage. There is also notable events where we can see potential incidents or potential alerts about the infrastructure and the network itself."
"The incident review pane is the best part of it because that is where the SOC lives. It is the heartbeat of what the SOC needs to do. You are able to start the investigative process. As you are sitting in the incident review pane, you see the alert, and from that one alert, which is called a notable alert, you can drill in and see all the different specific details that are tied to that."
"The ability to view all of these different logs, then drilling down into specific times or into specific data sources, has proved to be the greatest aspect in decreasing our troubleshooting overhead time."
"The ability to ingest any data and display it in a way that anyone can understand."
"They have approximately 50,000 predefined correlation rules, which is quite a lot, and I find that good."
"The site is constantly up, and it's been really easy to adjust the data."
 

Cons

"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."
"The solution needs to expand its access control and make it accessible through API."
"The product needs improvement from a filtering perspective."
"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 solution needs to improve its data retention. It should be greater than seven days. The product needs to improve its documentation as well."
"The Enterprise Security app could be improved. We have had trouble with it working from the first day."
"They can improve their support teams. They can also improve their capability of ingesting data from different IoT sources."
". Having a trial version or more training on Splunk would be helpful."
"Integrating tools and creating use cases could be easier. It's hard for a junior security engineer with only a couple of years of experience to write use cases. They can do it, but it's much easier in a solution like IBM QRadar. Setting conditions is like a multiple-choice type of thing. It's a more user-friendly process."
"The prices are complicated as we operate in a small third-world country."
"Splunk Enterprise Security incurs a significant cost because of the amount of data we send, but we are fine with the value we're getting for that price."
"It would be great if I could have a certain dialogue box in Splunk that uses innovative AI tools like ChatGPT, which are available now in the tech department."
"It needs more thoroughly tested releases. Every new big version (6, 7, etc.) has had so many bugs that it makes me wary of customers upgrading right away."
 

Pricing and Cost Advice

"The tool is an open source product."
"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 product is a little expensive."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"It is possible to use a developer's license, which is up to 10GB per day of volume traffic, which is usually enough for most use cases."
"This solution is costly. Splunk is obviously a great product, but you should only choose this product if you need all the features provided. Otherwise, if you don't need all the features to meet your requirements, there are probably other products that will be more cost-effective. It's cost versus the functionality requirement."
"Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost."
"I think the price could be improved."
"Personnel costs are saved by not having to involve the domain developers from multiple teams when tracing a problem that spans multiple platforms."
"Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises."
"Splunk Enterprise Security is not at all cost-friendly to be deployed in very small enterprises like start-ups."
