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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

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."
"I didn't know what to expect back in 2015 when we bought the product, but it's showing to be agile, scalable, and the people are very knowledgeable."
"The product was easy to deploy and easy to learn how to use, and the web console is the best I have seen when compared to other SIEMs."
"The correlation engine is extremely valuable because it uses machine learning to process information from the central manager and identifies issues in the network."
"LogRhythm is successfully employed in a lot of organizations."
"We take in around 750 million logs a day. We have a lot of products and that would be a lot of different panes of glass that we would have to look through otherwise. By centralizing, we can triage and take steps much more quickly than if we tried to man that many interfaces that come with the products."
"We looked at LogRhythm, and LogRhythm seemed to have a lot of the stuff built in, canned already."
"We have seen a massive increase in the amount of data that we can collect, the type of things that we can see, the way we can look at logs, the way we can get alerts, and the way can create our own customer roles, which has allowed us to customize the work in our environment."
"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

"Right now I know there's a big issue with reporting. It's challenging, at least for us, to do some of the reporting within the system itself."
"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."
"My biggest challenge always come back to log sources."
"We run across the odd vendor which we are using that we think are large players in their environment, but there is not necessarily a native support for their log ingestion per se, where it requires customization in order to be able to parse and accept their logs."
"It seems with all of the advanced features that we haven't quite figured them out. It is very complex."
"Out of 10, I would give it an eight. We upgraded our firewall and that broke our parsing rules and it took a while to get that all fixed, but other than that it's been great."
"Just integration into our ticketing system, which we're using service now."
"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."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"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."
"In the context of our country, the price of this solution is too high."
"I would rate the tool's pricing around eight out of ten."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"NextGen SIEM's pricing is moderate."
"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."
"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"It’s a single license platform."
