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.
TO
It consolidates all logs into one place and provides required features and functionalities
Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to do RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It has helped us centralize and have better visibility into devices on our network. We are better able to respond to threats in a timely manner."
"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."
"Their customer support is friendly and willing to help."
"The ability to investigate a particular period of time where you can analyze logs is its most valuable feature."
"It's reliable and the performance is good."
"The initial setup is pretty easy."
"I would say the most valuable feature of LogRhythm is that it has built-in UEBA functionality, among other basic Windows packages."
"It has allowed us to dive deeper into our network and figure out what is going on by parsing logs properly and being able to reduce the time it takes to work cases down from seven days to approximately two days."
"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."
"LogDNA consolidates all logs into one place, which is super valuable."
 

Cons

"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."
"I would like to see more integration with more products that are out there within the same security field."
"One of the challenges of the SIEM for the LogRhythm 7 platform is the amount of time it takes to bring new log sources into the MDI."
"Parsing is totally controlled by LogRhythm and they do not allow any partner or any third-party to handle this part and this is a key challenge on my end."
"Right now there is the concern about being able to gather all of the data into the system."
"In the next release, I would certainly like to see more HIPAA compliance. I would also like to see more integration with Palo Alto Networks, particularly their Traps, which is their endpoint solution."
"Appliance-based setups can sometimes pose scalability issues"
"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."
"Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue."
"No ability to encapsulate a query or a filter, and communicate or share that among the team."
 

Pricing and Cost Advice

"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"I give the price a six out of ten."
"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."
"In the context of our country, the price of this solution is too high."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"The product is inexpensive than other tools."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
