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

"LogRhythm really helps with our cybersecurity exposure because it gives us insights to make us more proactive versus reactive regarding events happening in our environment."
"PCI compliance was our main driver for purchasing LogRhythm, but it turns out there was just a ton of other information that really came from having that appliance, other than just being PCI compliant and checking that box for us."
"I am pretty impressed with it."
"One of the evidences we have that LogRhythm is being very successful for us is in this year's penetration test."
"It is a really good product with good support."
"This solution has been almost like a transformative change in how we detect and then respond to incidence."
"LogRhythm is a good product for what it is."
"It makes it possible to stay aware of much more of what's going on; we get an overview, a macro view that we can zoom in on as opposed to prior to that when we had individual panes of glass and might be stuck in the firewall interface for half a day while something going on is not getting addressed that we really should probably investigate."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"The main area of improvement is that the client must be installed on the computer for all of the functions to work."
"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."
"Sometimes the error-logging is not altogether helpful. For example, on an upgrade, a systems data processor, a Windows box, was throwing an error code like 1083. Then it just stopped and it died right out of the installer and nobody looked. We searched through Google and what it means is the Windows Firewall wasn't turned on so that it could create a rule for the product. Why wouldn't they bubble up that description so that I wouldn't have to call support and I could just know, "Okay, the firewall wasn't turned on. Turn it back on. Re-run the installer and keep going.""
"The initial setup is complex."
"The user interface needs improvement. The more the user can slide around and know what's going on, the better it will be."
"Better knowledge transfer during implementation. We definitely thought it was complex when we initially set it up, but that is usually just a single pain problem."
"When we had version 7.2.6, there were a lot of issues deploying that version and with the indexing. The indexer was unstable. So, we were not able to use the platform when we were on that version until we were able to upgrade to 7.3.4."
"We were having some challenges initially, especially ingesting those standard log sources. We ran into issues where it was not parsing correctly."
"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

"The product is inexpensive than other tools."
"It is a very cost-effective solution."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"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."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"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."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"It’s a single license platform."
