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.

A mature and affordable solution that is easy to install and easy to update

The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

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

Pros

"Quicker ability to troubleshoot the problem, find the problem, get it fixed, and get the customers back up and using our system."

"Customer service and technical support were both excellent, and we experienced no issues with stability or scalability while using the solution for security logging and traffic-aware reporting."

"It allows us to automate a lot of things with a smaller team."

"It gives us insight into our entire installation, where we are multiple sites, going as far as the East Coast to the Central West Coast."

"The LogRhythm AIE (Advanced Intelligence Engine) is very good at alerting my SOC to events of interest and potential security issues without flooding my team with noise."

"It is a big project, but very worthwhile, and LogRhythm has plenty of documentation, support people, professional services, and classes that can help get a business implemented and push them all the way to completion."

"SOAR is integrated with the dashboard that we use for threat management, and because it's all integrated, it is useful for us when we deploy something on-prem."

"SOAR is integrated with the dashboard that we use for threat management. Because it's all integrated, it is useful for us when we deploy something on-prem."

More LogRhythm SIEM pros

"We use Security Onion for internal vulnerability assessment."

"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."

"Security Onion is the most mature solution in the market."

Cons

"I would really like to see some type of group or global management for RIM policies,"

"Better integration with different services is needed, as there are quite a few platforms that we use that don't integrate very smoothly with LogRhythm."

"More features that I would like to see more development in are the automation and the smart response."

"LogRhythm SIEM can improve its user interface. The current interface is quite complex and can be challenging to navigate. While it offers many valuable features, understanding how to access and utilize them efficiently takes time. Simplifying the client console's user interface would significantly enhance the user experience and make it more user-friendly."

"I would like to see additional features around alarm management."

"We have a lot of alarms that get overlooked, there's not a lot of prominence to them."

"We're still struggling to get a real return on it and finding something that isn't false noise."

"My main thing I'd like to see is, when you're using canned reports, that they're not blank."

More LogRhythm SIEM cons

"Security Onion's user interface could be improved."

"The initial setup of the solution is a little bit difficult."

"The product is not easy to learn."

Pricing and Cost Advice

"It is a very cost-effective solution."

"Look for whatever will give you the most value. That's the main point. It is not one size fits all."

"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."

"I give the price a six out of ten."

"We have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."

"We work with French-speaking African countries, and it costs more than the average SIEM solution. Also, the pricing isn't too flexible. AlienVault, Splunk, and IBM QRadar are more suitable for customers on a tight budget."

"The license cost is around $10 per MPS."

"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."
