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

"In comparison to others, LogRhythm SIEM has certain features that other solutions are lacking; for example, user analytics and user behavior monitoring are features that some of the other SIEMs lack."
"LogRhythm lights up when an event occurs; as opposed to just giving us everything, it will piece things together for you and let you know that you probably should look at this, providing the evidence and making qualifying or investigations a little bit quicker and allowing us to close down on remediation times."
"If I look back to my other SIEM solution providers, the one we had before this, it's light years difference."
"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."
"Customer Service: It's the best there is. Technical Support: It's the best there is."
"It's definitely given us a lot of visibility into areas that we probably wouldn't have normal visibility into, such as code execution and things like that."
"What LogRhythm really excels at is its stability, since, in all the deployments that I have been involved in, there's no break-and-fix at all."
"It has far exceeded what I thought it was going to do for me in my job role."
"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

"I think where I see room for improvement for LogRhythm is probably granularization of log source types."
"LogRhythm's SOAR and NDR features don't stack up well against competitors. maybe integrating theme functionality as the other do. But in general, it's okay."
"Definitely expansion on log parsing. There are some obscure log sources that we don't currently have parsers for."
"The responses provided by the cloud team are inefficient."
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"We have a lot of alarms that get overlooked, there's not a lot of prominence to them."
"Right now there is the concern about being able to gather all of the data into the system."
"I do think there is room for improvement because the system is still running on the Windows Server platform. The problem with running on Windows is that it is not that good for scaling and providing for big deployment environments."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"The setup and licensing for small and medium size businesses is straightforward, though when it comes to the enterprise it pays to keep in mind the possibility for complications given all the extras and add-ons that may be required."
"The pricing is very reasonable and accessible compared to other products in the market but I am not very sure about the exact licensing cost per year for our company."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"It costs a great amount, but its pricing is competitive with some of the other vendors. For licensing and support, we pay about 20,000. There are no additional costs or anything like that."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"I have seen a measurable decrease in the mean time to detect and respond to threats. We went from not detecting them to detecting them. We can actually pick up what is anomalous in our network now."
"It is a very cost-effective solution."
"In the context of our country, the price of this solution is too high."
"It’s a single license platform."
