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

"We have seen a massive increase in the amount of data that we can collect, the type of things that we can see, the way we can look at logs, the way we can get alerts, and the way can create our own customer roles, which has allowed us to customize the work in our environment."
"It's definitely given us a lot of visibility into areas that we probably wouldn't have normal visibility into, such as code execution and things like that."
"What I found most helpful out of it is the ability to see all of the same data, that I would get from my appliances, in one place."
"The AI engine is what I like the most; it’s all in how LogRhythm correlates the events that it is receiving, taking a lot of guesswork away from the analyst so we don’t have to reinvent the wheel."
"This solution has been almost like a transformative change in how we detect and then respond to incidence."
"The PCI compliance pieces that help us produce reports for our external auditor, and their support."
"LogRhythm SIEM gives us a sense of confidence that, during an investigation, it's a solid source of information that we can use to complement the investigation or perhaps complete the entire investigation within the SIEM."
"We went with LogRhythm because of cost, administration, and ease of use when you're in the tool."
"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'm not sure if I would recommend the solution to others as they still need to improve a few things."
"The installation was a bit complex because we are running a virtual infrastructure."
"I face stability issues every quarter that necessitate corrective maintenance."
"I would like the log management database to perform more efficiently."
"In terms of blind spots, we are looking for more improvements since we don't have visibility over everything."
"We would like to see more things out of the console into the web UI. I guess this is what they are doing in 7.4."
"I would like a more fuller implementation of STIX/TAXII so I can pull in some of the government lists without having to go implement a whole new STIX/TAXII platform."
"Sometimes it's a challenge to bring it to the second level of support and get the answers that we need."
"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

"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."
"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."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"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."
"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 solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"It’s a single license platform."
