User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.

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

"File Integrity Monitoring is really valuable because we have it set up on our core assets. This is one of the key features that I utilize. We also use it quite a lot for event management to do reporting."
"The initial setup is pretty easy."
"Compliance reporting is another great feature of this product. It has built in reports right out of the box."
"LogRhythm has increased productivity because all the tools that we need are in the web UI, allowing us to find threats on our network fast and efficiently."
"It's very easy to create the correlation rules with LogRhythm, and there are some advanced features like SIEM and UEBA, which are also very valuable."
"We use this solution to examine disparate log sources and provide a cohesive method to search for anomalous behavior."
"Provides visibility into the network."
"LogRhythm has shown to us, to this point in time, that it has the capabilities of being able to deliver actionable intelligence to the security engineers and analysts."
"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

"There are other security technologies outside of this SIEM that should be inside of this SIEM. I can see in their roadmap that they're trying to address a lot of these things, and have these technologies built into the solution, because there is no point in going to another vendor or opening up a second window to obtain the data that you need."
"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."
"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."
"Right now there is the concern about being able to gather all of the data into the system."
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"I would probably look for more things to go into the web console that is currently on the fat client."
"The log storage capacity should be increased."
"It should have some more message monitoring features. It can also have some free message monitoring tools."
"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

"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"I give the price a six out of ten."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"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."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"The product is inexpensive than other tools."
"NextGen SIEM's pricing is moderate."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"It’s a single license platform."
