Provides strong detection capabilities but requires improvements in parsing and stability
I cannot think of any specific features that LogRhythm SIEM can improve upon since it supports a wide variety of major vendors. However, they need to improve their parsing techniques; the tool should understand various devices and present data in a human-readable format. For example, if a personal Android mobile needs to be integrated, LogRhythm SIEM should be able to parse that data effectively. They also need to improve their database of supported devices to cover smaller vendors alongside the major players, allowing for better global reach and usability. I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.

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

"We use this solution to examine disparate log sources and provide a cohesive method to search for anomalous behavior."
"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."
"NextGen SIEM's best feature is how it presents logs."
"LogRhythm NextGen SIEM covers all our primary security analysis needs. It makes it easier for us to analyze threats and improves our response times. It's a versatile platform that performs queries fast compared to other SIEM solutions."
"The initial setup process is very user-friendly."
"The artificial intelligence engine."
"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."
"Automations are very valuable. It provides the ability to automate some of our small use cases. The ability to integrate with other products that use an API is also very useful. LogRhythm has a plugin for it that we can connect and start to move down towards the path of a single pane of glass instead of having multiple or different tools."
"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

"Scalability-wise, it's not that great."
"Right now there is the concern about being able to gather all of the data into the system."
"Better integration with different services is needed, as there are quite a few platforms that we use that don't integrate very smoothly with LogRhythm."
"My big thing is the easability. I don't like to go to two different systems. The fat client that you have to install to configure it, then the web console which is just for reporting and analysis. These features need to collapse, and it needs to be in a single solution. Going through the web solution in the future is the way to do it, because right now, it is a bit cumbersome."
"I think there is room for improvement because the system is still running on the Windows Server platform. The problem with running on Windows is that it is not that good for scaling and providing for big deployment environments."
"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."
"It should have some more message monitoring features. It can also have some free message monitoring tools."
"I would like to suggest that they should improve their usage of third party tools for making dashboards and reports. If they would create their own tools for dashboard and report, it would be much better in terms of security purposes."
"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

"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"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."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"In the context of our country, the price of this solution is too high."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"The product is inexpensive than other tools."
"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."
"It’s a single license platform."
