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

"It has improved the organization a great deal because we're able to see much more data, see what activity is actually being found in the network, what type of threats we're encountering, and whatever would not have been seen previously because it aggregates all the logs together and flags us according to the alerts being triggered."
"If I look back to my other SIEM solution providers, the one we had before this, it's light years difference."
"The alarm functions have helped us cut down on the manual work. They bubble things up to us instead of our having to go look for stuff. Also, from an operational perspective, day to day, the Case Management functions are really useful for us. They allow us to track what we see in the incidents that we have."
"Mostly for us the most valuable feature is its aggregation of all the logs into a single platform, and then doing the real-time monitoring based on that."
"It's reliable and the performance is good."
"We should be able to response to threats and gain visibility into our environment that we don't currently have."
"The product is great for medium to large-scale organizations."
"Our security program's maturity has been transformational for my staff."
"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

"Their ticketing system for managing cases can be improved. The current system works and gets the job done, but it is very bare-bones and basic."
"Sometimes the Platform Manager crashes because it's built around Windows."
"I'm not sure if I would recommend the solution to others as they still need to improve a few things."
"I have Windows administrators who will remove the agent when they think that that's what's fouling up their upgrade or their install or their reconfiguration, etc. The first thing they do is to turn off the antivirus, turn down the firewall, and take off anything else. They don't realize that the LogRhythm agent is just sitting there monitoring. Most antivirus products have application protection features built-in where, if I'm an admin on a box, I can't uninstall antivirus. I need to have to the antivirus admin password to do that."
"We have to use tech support pretty regularly and it is sometimes not very good."
"It should have some more message monitoring features. It can also have some free message monitoring tools."
"Their ticketing system for managing cases can be improved. They can either do that or adopt some of the open-source ticket systems into theirs. The current system works and gets the job done, but it is very bare-bones and basic. There are some things that could be improved there. They should also bring in more threat intelligence into the product and also probably start to look into the integration of more cloud or SAS products for ingesting logs. They're doing the work, but with the explosion of COVID, a lot of businesses have started to move towards more cloud applications or SAS applications. There is a whole diverse suite of SAS products out there, which is a challenge for them and I get it. They seem to be focusing on the big ones, but it'll be nice to be able to, for example, pull in Microsoft logs from Office 365. They are working towards a better way of doing that, and they have a product in the pipeline to pull logs in from other SAS applications. The biggest thing for them is going to be moving away from a Windows Server infrastructure into a straight-up Linux, which is more stable in my eyes. For the backend, they can maybe move into more of an up-to-date Elastic search engine and use less of Microsoft products."
"Sometimes the error-logging is not altogether helpful. There have been many times where I've been disappointed, where I'll ramp an agent up to Verbose and it will say, "LogRhythm critical error, the agent won't bind to a NIC," or the like, and I end up with no really actionable or identifiable information coming in, even though I've ramped up the logging level."
"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

"In comparison to the competition, they are more affordable. This allows us to do more with less."
"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."
"NextGen SIEM's pricing is moderate."
"The product is inexpensive than other tools."
"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."
"We work with French-speaking African countries, and it costs more than the average SIEM solution. Also, the pricing isn't too flexible. AlienVault, Splunk, and IBM QRadar are more suitable for customers on a tight budget."
"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."
"It’s a single license platform."
