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

"Technical support is very helpful and responsive."
"The most valuable features would be the automation, reporting, and the support."
"So far we're pretty happy with the overall functionality of the system."
"LogRhythm is a good product for what it is."
"This solution has been almost like a transformative change in how we detect and then respond to incidence."
"All in all, it's one of the best SIEMs, as a total package, that I've worked with."
"We should be able to response to threats and gain visibility into our environment that we don't currently have."
"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."
"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

"For instance, we were trying to deal with pass the hash, which is a very common exploit and LogRhythm tech support told us they were just going turn that rule off, that we can't use it."
"We are seeing performance issues with the appliance."
"The main area of improvement is that the client must be installed on the computer for all of the functions to work."
"There used to be the ability to create alarms based on message text that was included in LR Version 6.x that has been removed in LogRhythm 7.x, and on that, I would like to see it added back."
"Key challenges are our users and network."
"There are other security technologies outside of this SIEM that should be inside of this SIEM."
"We have a lot of alarms that get overlooked, there's not a lot of prominence to them."
"The responses provided by the cloud team are inefficient."
"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 for whatever will give you the most value. That's the main point. It is not one size fits all."
"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."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"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 give the price a six out of ten."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"I would rate the tool's pricing around eight out of ten."
"It’s a single license platform."
