SumitKumar20 - PeerSpot reviewer
Security Engineer at Granicus Inc.
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 SIEM has some valuable features, including its ability to maintain backups of events and manage alerts separately through an engine that handles content and administration tasks."
"Now it pulls it all into one spot and we're actually able to correlate data and say, "Hey look, this person's really actually being shady," and go from there."
"We have seen a measurable decrease in the mean time when detecting and responding to threats."
"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."
"Hands down, one of the best security platforms I've seen, easy to use, easy to scale, with huge visibility into your network so you just see everything and you see it easily."
"We went through a competitive comparison of the three leading platforms out there, and it was an easy win, not only from the technology side, but from the company with its support."
"LogRhythm SIEM gives us a sense of confidence that, during an investigation, it's a solid source of information that we can use to complement the investigation or perhaps complete the entire investigation within the SIEM."
"I would say the most valuable feature of LogRhythm is that it has built-in UEBA functionality, among other basic Windows packages."
"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 face stability issues every quarter that necessitate corrective maintenance."
"NextGen SIEM has separate rules for AI, advanced intelligence, and MP rules - it would be better to have a centralized way to write the rules and create alarms."
"Ease and setup would be a major improvement because it took over a week to get it all up and running, and that didn't even count tweaking it and getting it all set up for my environment."
"Functionality, ease of use. There are a few gotchas in the applications."
"We do about 750 million a day and some days we do 715 million. Some days we do 820 million or 1.2 billion. But there's no way to drill in and find out: "Where did I get 400,000 extra logs today?" What was going on in my environment that I was able to absorb that peak? I have no way to identify it without running reports, which will produce a long-running PDF that I have to somehow compare to another long-running PDF... I would like to see like profiling behavior awareness around systems like they've been gunned to do around users with UEBA."
"Better correlation of all events: We seem to get a lot of misinterpreted data coming from multiple sources."
"In terms of just stability of the product, sometimes we have run into some issues there."
"In terms of improvement, their community boards, where to go find things, as a customer. As they're growing and they're moving stuff around, it would be nice if we knew exactly where to find what."
"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

"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."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"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 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."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"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."
"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 nice thing about LogRhythm is you can either use the agents, getting a certain number of agents with your license depending on how you want to go, and those agents do a lot of cool things, or you can use CIS Log host, then you have like an unlimited number of them."
"It’s a single license platform."
