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 now have a central point of monitoring for all potential threats."
"I have found the Advanced Intelligence Engine has provided the most value to us because we can customize alarms based on our requirements and have created hundreds of alarms that notify different people for different scenarios."
"One of the main features that I like about LogRhythm NextGen SIEM is that there are a lot of pre-built pieces. Like with our AV, we didn't have to tell it how to read the logs; they already had it pre-made. So, we essentially just had to follow their guide to get the logs imported in and set up some rules for it. We've only had to manually create the parsing rules for a few of our vendors so that we could interpret the logs correctly. Most of them had already been pre-created for us."
"As a healthcare company, what we use it for is compliance, then to protect our data from exaltation."
"It's positively affected our overall rate of efficiency."
"NextGen SIEM's best feature is how it presents logs."
"It gives us insight into our entire installation, where we are multiple sites, going as far as the East Coast to the Central West Coast."
"This solution has improved our organization in many different ways. The biggest benefit is being able to view all information in one dashboard instead of having to look at several different applications and dashboards. I can see information across our entire environment and every aspect of our network."
"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 there is the concern about being able to gather all of the data into the system."
"We've had issues with scaling and local support."
"Scalability misses the mark sometimes, especially when you have an integrated disaster recovery built into the solution."
"I would really like to see some type of group or global management for RIM policies,"
"Their ticketing system for managing cases can be improved. They can either do that or adopt some of the open-source ticket systems into theirs. The current system works and gets the job done, but it is very bare-bones and basic. There are some things that could be improved there. They should also bring in more threat intelligence into the product and also probably start to look into the integration of more cloud or SAS products for ingesting logs. They're doing the work, but with the explosion of COVID, a lot of businesses have started to move towards more cloud applications or SAS applications. There is a whole diverse suite of SAS products out there, which is a challenge for them and I get it. They seem to be focusing on the big ones, but it'll be nice to be able to, for example, pull in Microsoft logs from Office 365. They are working towards a better way of doing that, and they have a product in the pipeline to pull logs in from other SAS applications. The biggest thing for them is going to be moving away from a Windows Server infrastructure into a straight-up Linux, which is more stable in my eyes. For the backend, they can maybe move into more of an up-to-date Elastic search engine and use less of Microsoft products."
"The reporting on the dashboard should be improved from a management perspective. It would be helpful if they adjusted the colors and the presentation to make things clearer and easier to read."
"We've tried to work with a couple of engineering department guys there. We've called them and called them but we never hear anything back."
"LogRhythm NextGen SIEM is currently based only on the Windows platform. This means that some of our customers have to purchase a Windows license elsewhere. If LogRhythm can move to a Linux platform or a proprietary platform, it would be very helpful."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."
"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."
"The support which allows more customized to the environment when we are deploying new systems is called Professional Service and is very expensive. The technical annual support and there is an annual fee."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"It is a very cost-effective solution."
"It’s a single license platform."
