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

"The user interface is good."
"The most useful feature that I've found so far is the search function. I like all the different ways you're able to search through metadata and the different ways you're able to correlate or search through logs to find out what's going on."
"LogRhythm does a very good job of helping SOCs manage their workflows."
"The AI Engine can take an event and correlate it into something else giving us meaningful context regarding what is going on. We integrated it in with our ticketing system, so if an alarm fires, it raises a ticket in our system."
"The most valuable feature of LogRhythm for me is the ability to correlate logs throughout many different log sources."
"Overall, my rating for LogRhythm SIEM is nine out of ten."
"NextGen SIEM's most valuable feature is its user-friendliness."
"We integrated Azure logs with it and that makes it simpler. Rather than having to log into the portal, we can just check everything in one place. We can compare those to our Windows and host logs to see if any problems correlate between them."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"I face stability issues every quarter that necessitate corrective maintenance."
"LogRhythm's SOAR and NDR features don't stack up well against competitors. maybe integrating theme functionality as the other do. But in general, it's okay."
"We had a little bit of difficulty implementing a disaster recovery situation because it was leveraging only Microsoft native DNS and it wouldn't work with our Infoblox DNS deployment that we use in our environment. They've been working on that behind the scenes."
"NextGen SIEM's integration with other software is good but could be improved."
"The pricing is the only problem."
"For our market, the solution is quite expensive. It would be ideal if they could work on and improve their existing pricing plans to help make it more affordable in our country."
"LogRhythm NextGen SIEM could improve by adding more applications for the banking sector. There are not any custom applications at this time."
"It will definitely help if the parsing side would be much easier, meaning it would be better if we could easily make adjustments on the parser, both on standard and non-standard log sources."
"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

"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"The license cost is around $10 per MPS."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"The setup and licensing for small and medium size businesses is straightforward, though when it comes to the enterprise it pays to keep in mind the possibility for complications given all the extras and add-ons that may be required."
"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."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"I give the price a six out of ten."
"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."
