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

"You can request support and they respond immediately."
"What LogRhythm really excels at is its stability, since, in all the deployments that I have been involved in, there's no break-and-fix at all."
"The ability to drill down and pivot from an event is one of the biggest advantage the product has compared to other things that I have seen in the market."
"So far, my experience has been seamless."
"The web interface is awesome, it's very intuitive and gives a lot of great information."
"It has centralized monitoring for our security operations. Therefore, it improves our analysts' work."
"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."
"Alarms are the most valuable feature. We also like the dashboard and how things are at your fingertips. The fact that we can now edit the report templates is going to be a great thing."
"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."
"We're easily saving at least one hour per day using this solution."
"The platform has significantly enhanced our operational insight into the overall Microsoft 365 environment."
"The main Microsoft feature is that it offers common integration of services, of data, of identity, meaning user accounts, user access, and privileged access."
 

Cons

"I think a must-have feature would be better reporting. The reports do not provide information such as, who are your top ten end users generating the most activity within the environment, or appliances, per se, so that's very limited."
"For instance, we were trying to deal with pass the hash, which is a very common exploit and LogRhythm tech support told us they were just going turn that rule off, that we can't use it."
"Stability is not great but I think that's our issue."
"Appliance-based setups can sometimes pose scalability issues"
"It's not easy for someone new to the solution."
"We are seeing performance issues with the appliance."
"We use Windows Event Forwarding to collect the logs from our Windows clients, and the logs get aggregated as one data source on that collector. Therefore, finding logs specific to one particular Windows system requires some creativity in how we search the SIEM."
"I would really love to be able to take some of the data and not have to export it to a CSV file, so I can pull it into Excel to turn it into some other kind of graph."
"We are still in the early stages of leveraging Microsoft Purview Audit. Currently, it's primarily used for the audit function."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"We do have a Denial of Access happening."
"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."
 

Pricing and Cost Advice

"In comparison to the competition, they are more affordable. This allows us to do more with less."
"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."
"It is a very cost-effective solution."
"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."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"I would rate the tool's pricing around eight out of ten."
"The product is inexpensive than other tools."
