SumitKumar20 - PeerSpot reviewer
Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"Its benefits are broad. The solution isn't necessarily made to do any one thing, but it can do anything you tell it to. It is able to tackle any different type or size of job."
"When it comes to dealing with support, all my interactions have been great. Everyone has known what they're doing and have been quick to respond. They seem to always know the answer. I haven't stumped anybody yet."
"NextGen SIEM's best feature is how it presents logs."
"One of the main features that I like about LogRhythm NextGen SIEM is that there are a lot of pre-built pieces. Like with our AV, we didn't have to tell it how to read the logs; they already had it pre-made. So, we essentially just had to follow their guide to get the logs imported in and set up some rules for it. We've only had to manually create the parsing rules for a few of our vendors so that we could interpret the logs correctly. Most of them had already been pre-created for us."
"The AI Engine can take an event and correlate it into something else giving us meaningful context regarding what is going on. We integrated it in with our ticketing system, so if an alarm fires, it raises a ticket in our system."
"We integrated Azure logs with it and that makes it simpler. Rather than having to log into the portal, we can just check everything in one place. We can compare those to our Windows and host logs to see if any problems correlate between them."
"In general, the visibility of events and advanced analysis of events are good."
"Its ability to work with all different sorts of log sources has been extremely valuable."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"The web and on-premise console interface should be the same instead of having a separate engine for each."
"I would like a more fuller implementation of STIX/TAXII so I can pull in some of the government lists without having to go implement a whole new STIX/TAXII platform."
"I would really love to be able to take some of the data and not have to export it to a CSV file, so I can pull it into Excel to turn it into some other kind of graph."
"I would really like to see some type of group or global management for RIM policies,"
"The SOAR capabilities need improvements as they currently require programming knowledge."
"The initial setup is not so easy because it is quite a process."
"The pricing is the only problem."
"When we originally got LogRhythm, their tech support was fantastic, and I loved them. Now, we don't quite get as quick of a response. I've been disappointed in the more recent tech support. When you call in, they'll say that they will get you somebody, and you'll finally get someone who will contact you back a day or so later. Whereas before, I would get help right away."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"I give the price a six out of ten."
"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"The license cost is around $10 per MPS."
"In the context of our country, the price of this solution is too high."
"We have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."
"I would recommend that whatever sales quotes to them upfront, they will probably go up. Because they are probably going to outgrow that very quickly or once they start getting everything into it, they are going to have to move up anyway."
"NextGen SIEM's pricing is moderate."
"It’s a single license platform."
