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

"Its benefits are broad. The solution isn't necessarily made to do any one thing, but it can do anything you tell it to. It is able to tackle any different type or size of job."
"For me, the NERC compliance modules are probably the best thing, and the system monitors really pick up a lot for me, helping you get an eagle-eye view and then delve down granularly, and the ease of that is pretty amazing."
"We have seen a measurable decrease in the mean time to detect and respond to threats."
"Overall, my rating for LogRhythm SIEM is nine out of ten."
"It has definitely improved our security program's maturity, because we have visibility that we didn't have before."
"We should be able to response to threats and gain visibility into our environment that we don't currently have."
"I would recommend NextGen SIEM to other users as it is a leading solution with new features at a better price than competitors like Splunk and QRadar."
"LogRhythm is successfully employed in a lot of organizations."
"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 would like to see case management become more independent from LogRhythm itself."
"Ease and setup would be a major improvement because it took over a week to get it all up and running, and that didn't even count tweaking it and getting it all set up for my environment."
"Sometimes the Platform Manager crashes because it's built around Windows."
"Definitely expansion on log parsing. There are some obscure log sources that we don't currently have parsers for."
"The responses provided by the cloud team are inefficient."
"The reporting engine is poor in comparison to other areas. It should be moved to the web interface to improve its functionality and usability."
"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."
"It is a product that is very hard to use."
"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

"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"NextGen SIEM's pricing is moderate."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"The license cost is around $10 per MPS."
"I would rate the tool's pricing around eight out of ten."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"In the context of our country, the price of this solution is too high."
"It’s a single license platform."
