Advanced threat detection has improved investigations but complexity and resource use need refinement
LogRhythm SIEM could learn from Wazuh, as Wazuh has a built-in mechanism that allows you to write custom scripting and scripts through languages that Wazuh can then trigger, which is somewhat better and more matured in Wazuh compared to LogRhythm SIEM. Additionally, the parsers that I write for LogRhythm SIEM tend to get quite complex for log parsing, while with Wazuh, I can achieve a similar parser with much less complexity. Those are some of the pain points that some of our customers have been expressing. If LogRhythm SIEM could make a lightweight version of their solution, that would be quite competitive because some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity. Therefore, they have been moved to Wazuh, which I am deploying for them. Even though LogRhythm SIEM has extremely good capabilities, their resource utilization is too heavy for certain customers, so if they could make a separate, lightweight version, that would be quite beneficial.

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

"It's definitely given us a lot of visibility into areas that we probably wouldn't have normal visibility into, such as code execution and things like that."
"From a security standpoint, it's the solution to have, in regards to LogRhythm."
"Being able to see when one of our assets is down and being able to restart it really quickly has been a definite benefit."
"Support after implementation is probably the biggest."
"NextGen SIEM's most valuable feature is its user-friendliness."
"For my situation, besides the investigation that LogRhythm offers, it's the AI Engine rule set that it offers, and it has brought us more significant changes in how we alarm and notify our users about what's going on in our network."
"Scalability is extremely great."
"The initial setup process is very user-friendly."
"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."
"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."
 

Cons

"There have been issues with the hardware which has resulted in the LRM going down a few times."
"The initial setup is not so easy because it is quite a process."
"Scalability has been a little tougher for us."
"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."
"More help and assistance with some of the open source products, everything seems to be focused on Windows versus giving some guidance and some documentation on how to use it."
"Going into the beta, stability was very good, but in the beta it's not been as great for us lately."
"I would like to see our vulnerabilities counter. We will be using Tenable to fill that void right now."
"The solution is likely not the best option for a smaller organization."
"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."
"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."
 

Pricing and Cost Advice

"It is a very cost-effective solution."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"The license cost is around $10 per MPS."
"I give the price a six out of ten."
"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."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"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."
