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

"LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis."
"Straight away it was fairly evident that the LogRhythm application itself, and the agent roll-out, was straight out of the box."
"We really appreciate the new cloud functionality."
"Provides visibility into the network."
"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."
"From a security standpoint, it's the solution to have, in regards to LogRhythm."
"The web interface is awesome, it's very intuitive and gives a lot of great information."
"Regarding meeting those goals, in the last two months that we've had LogRhythm it's been very good."
"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

"One of the challenges of the SIEM for the LogRhythm 7 platform is the amount of time it takes to bring new log sources into the MDI."
"The pricing is the only problem."
"We use Windows Event Forwarding to collect the logs from our Windows clients, and the logs get aggregated as one data source on that collector. Therefore, finding logs specific to one particular Windows system requires some creativity in how we search the SIEM."
"The log storage capacity should be increased."
"Technical support could use a little work in the terms of responding back. The feedback that we received is they do need a little more staff."
"When you get LogRhythm out-of-the-box, there are so many knobs to turn and so many things to configure and set up, that it's almost impossible to do it on your own, as an enterprise senior engineer."
"We've had issues with scaling and local support."
"Parsing is totally controlled by LogRhythm and they do not allow any partner or any third-party to handle this part and this is a key challenge on my end."
"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

"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."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"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 think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"I give the price a six out of ten."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"I would recommend that whatever sales quotes to them upfront, they will probably go up. Because they are probably going to outgrow that very quickly or once they start getting everything into it, they are going to have to move up anyway."
"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."
"It’s a single license platform."
