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.

Hands-on monitoring has built my threat detection skills and now supports my graduate research

The biggest challenges I have experienced with Security Onion are the learning curve and resource requirements, as it is not necessarily something you can install and immediately understand without networking and Linux knowledge. I actually encountered an HTTP 500 error with the management interface recently, which required troubleshooting and expanding my storage, showing me how important storage planning and system maintenance are when running Security Onion. What I would improve about Security Onion is probably the documentation around troubleshooting common issues, particularly storage management, and making the interface more approachable for new users. Having documentation of what works best would help, especially since you can have nodes or have it all built-in one as a standalone. If you use nodes, you have to have several different Security Onion instances downloaded, then have a manager and connect all of them together.

Quotes from Members

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

Pros

"We now have a central point of monitoring for all potential threats."

"The LogRhythm support system is phenomenal."

"For the same price, we have been able to go from a SIEM that could only manage about 20 percent of our environment to a full 100 percent coverage of all the devices on our network."

"LogRhythm has been a major step with giving me file integrity monitoring, the SIEM capabilities, log collection, a lot of things that we didn't have before."

"We have NetFlow information going into it, so we can examine a lot of traffic patterns and anomalies, especially if something stands out and is not the baseline. This helps a lot."

"As a healthcare company, what we use it for is compliance, then to protect our data from exaltation."

"The consolidation of the logs and being able to manage the items we have coming in -- all in one product -- has really helped this company a lot."

"LogRhythm's correlation capabilities (part of the AIE component) is much better than Splunk's, and the solution as a whole is generally cheaper and easier to implement than ArcSight."

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 a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."

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

"What I appreciate most about Security Onion is that it combines multiple security monitoring tools into one platform."

"Security Onion has positively impacted my organization by enabling students to analyze logs, understand network traffic, comprehend intrusion detection, and utilize threat hunting and incident response skills in a practical environment, which are best practices we have implemented with the students."

Cons

"The ability to customize certain features of the product."

"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."

"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."

"We are seeing performance issues with the appliance."

"I would say the thing that I'd like to see the LogRhythm do a better job of is staying ahead of the curve as it relates to things like cloud."

"We need to get better training for things like creating code and playlists. The way it's done now takes a long time."

"Functionality, ease of use. There are a few gotchas in the applications."

"After a year-and-a-half, we're not stable yet. Every time we think we're stable for a week or two, we wake up the next morning to another million logs backlogged somewhere."

More LogRhythm SIEM cons

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

"The product is not easy to learn."

"Security Onion can be made easier to set up initially, as it is somewhat difficult at the start, but once configured, it becomes a great tool to use."

"One of the improvements for Security Onion could be to address the issue of many logs and false positive alerts by reducing the number of false positives, as storage management is very hard sometimes due to a lack of storage space for logs, and they could implement methods to expand storage."

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

"The biggest challenges I have experienced with Security Onion are the learning curve and resource requirements, as it is not necessarily something you can install and immediately understand without networking and Linux knowledge."

Pricing and Cost Advice

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

"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."

"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."

"The product is inexpensive than other tools."

"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."

"In comparison to the competition, they are more affordable. This allows us to do more with less."

"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."

"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."
