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.

Integrated auditing has strengthened data retention and improved incident investigations
I have seen areas for improvement, specifically in Microsoft Purview Audit or in general about Microsoft. I have had a situation with documentation. I had a customer who wanted to create alerts and they had Microsoft 365 Business Premium. In the documentation, it was noted that this license is enough for creating alerts. When we tried to make them, we noticed they cannot do it with Microsoft 365 E3 because the customer had limited features to manage alerts. The customer had to buy E3. We created Microsoft support requests, and they confirmed that the documentation displayed not the real situation and they have been going to update documentation. The same situation occurred now with implementing Microsoft Purview Audit in the last autumn. eDiscovery was combined with search and content search, and the documentation was not clear at the beginning. It was a little difficult to describe to customers that now it is a part of eDiscovery. Content search is a very simple functionality, while eDiscovery is a little difficult. I am not entirely sure why Microsoft is going in the way of combining these services because they are the same. However, for a customer who has never seen these services, it is difficult to understand quickly. The same situation occurs with litigation holds and some other holds. For any mail, I am trying to keep data. For example, emails are held for a year or two years, ten years, it does not matter. It is difficult to understand where to find this data and where these emails are being held. I need to use eDiscovery to find out all deleted data that was kept somewhere in some hidden folders of the mailbox. Regular customers and regular administrators know that on-premises Exchange, for example, allows them to find the data in some repository and review the list of kept data. However, with this hold, we do not have any functionality to review the list of kept data. It is difficult to understand for customers how to work with this. I had a case where I spent three or four hours working deeply with a customer to explain how to work with eDiscovery, why Content Search is not there when it was before, what is an eDiscovery case, and why we are talking about all of this just to review a list of kept emails. This is difficult.

Quotes from Members

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

Pros

"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."
"The initial setup is pretty easy."
"In general, the visibility of events and advanced analysis of events are good."
"The most valuable feature to me is certainly the CloudAI, which I have been a beta tester of, and also the SIEM capabilities and automation."
"Regarding meeting those goals, in the last two months that we've had LogRhythm it's been very good."
"LogRhythm allows our IT/IS teams to quickly identify issues across the enterprise."
"We have to be able to show the evidence, and LogRhythm does a great job of putting it forward and making it easy to create reports with nice looking dashboards, which show off what we are doing as a security program."
"Provides visibility into the network."
"The main Microsoft feature is that it offers common integration of services, of data, of identity, meaning user accounts, user access, and privileged access."
"We're easily saving at least one hour per day using this solution."
"The overall user experience with Microsoft Purview Audit is of higher quality than when it was branded as Compliance Center, and Microsoft consistently updates and evolves functionalities and the overall experience."
"The platform has significantly enhanced our operational insight into the overall Microsoft 365 environment."
 

Cons

"We have run into problems with stability going through upgrade processes. Recently, we have been on the front edge of the upgrade path. When that happens we tend to run into issues either with certain functionality not working after the upgrades or stability issues because of the upgrades."
"I think where I see room for improvement for LogRhythm is probably granularization of log source types."
"The reporting aspect is difficult to use and very difficult to get your own reports."
"The customer support system is time-consuming and needs to be improved because it is not very good."
"The integration is slightly difficult with other assets, like EDR technologies or firewalls."
"There have been issues with the hardware which has resulted in the LRM going down a few times."
"One thing we have mentioned to them before is that we'd like to be able to do searches, or drill-downs, directly from an alarm. When you click it and the Inspector tab slides out, that might be a good place to be able to click the host to search for the last 24 hours. I know the search is right there but it would be even nicer to just click that and then have an option to search something there."
"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."
"I had a case where I spent three or four hours working deeply with a customer to explain how to work with eDiscovery, why Content Search is not there when it was before, what is an eDiscovery case, and why we are talking about all of this just to review a list of kept emails."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"We do have a Denial of Access happening."
"We are still in the early stages of leveraging Microsoft Purview Audit. Currently, it's primarily used for the audit function."
 

Pricing and Cost Advice

"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."
"The license cost is around $10 per MPS."
"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."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
