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.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Our impression is the solution will be excellent toward meeting our existing security challenges."
"We just had a great experience all round, and when comparing feature sets, the web interface to the alarm drill downs, the AI Engine drill downs, to the network monitor product, it was definitely on the top of the list."
"The most valuable features would be the automation, reporting, and the support."
"Support after implementation is probably the biggest."
"Our clients enjoy having one dashboard to monitor their environments in real time."
"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."
"LogRhythm improves our organization by giving us insight into user activity and potential security threats, and our mean time to detect and respond has really improved with LogRhythm."
"LogRhythm really helps with our cybersecurity exposure because it gives us insights to make us more proactive versus reactive regarding events happening in our environment."
"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

"It should have some more message monitoring features. It can also have some free message monitoring tools."
"More help and assistance with some of the open source products, everything seems to be focused on Windows versus giving some guidance and some documentation on how to use it."
"There have been issues with the hardware which has resulted in the LRM going down a few times."
"I wouldn't give them a 10 out of 10 because there is definitely some room for improvement as far as in the GUI."
"The installation was a bit complex because we are running a virtual infrastructure."
"I would really love to be able to take some of the data and not have to export it to a CSV file, so I can pull it into Excel to turn it into some other kind of graph."
"Logging improvements. I think that the template to reporting is just difficult, it's hard to go back."
"Apparently, it's sitting in a state that's getting a little stale."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"I have seen a measurable decrease in the mean time to detect and respond to threats. We went from not detecting them to detecting them. We can actually pick up what is anomalous in our network now."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"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."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"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."
"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 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."
"It’s a single license platform."
