Cyber Security Engineer at Diyar United Company
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.

Has ensured compliance by centralizing log data and supporting secure connections
We currently do not use that feature. We currently have just an open-source release, not a premium release. My boss has indicated that he wants to buy a premium syslog-ng version next month. I think we can use other features of this tool in the future. In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it.

Quotes from Members

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

Pros

"The most valuable feature of LogRhythm for me is the ability to correlate logs throughout many different log sources."
"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."
"The most valuable features of the solution are network monitoring, user behavior analytics, and log collection."
"It has centralized monitoring for our security operations. Therefore, it improves our analysts' work."
"Currently, we are in the implementation phase. LogRhythm is better than QRadar from the point of view of collecting Windows events. It has a much higher view. You can enable monitoring by default."
"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."
"I like LogRhythm's ease of use. The solution has improved compared to previous versions. It had many issues before, like integration, the console, creating reports, false positives, etc. The AI engine has made it stronger in the latest version."
"In general, the visibility of events and advanced analysis of events are good."
"We chose syslog-ng because it is easy to install, easy to maintain, easy to update, and due to the fact that all data arrive in raw format, we can manipulate it as we want."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"Syslog-ng has a separate config file in addition to the core configuration."
"Syslog-ng provides easy access to all my logs. It helps me show managers and other clients precisely where an incident occurred. I also like it because you can integrate syslog-ng with multiple solutions to allow real-time monitoring."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"For us, the most valuable feature is the use of compound search for searching logs at a specific time, by a specific user, or specific behavior."
"What I appreciate most about syslog-ng is its configuration; its C-style config is much easier to understand, read, and write than other popular solutions such as syslog or rsyslog."
 

Cons

"My biggest complaint is documentation. Everyone tells me, "We have documentation on the Community site." I have searched for different types of documentation on numerous occasions, and it might be there, but it's not easily findable."
"I would like it to do a lot of the automation (which I still need to learn more about), because I am essentially a one man shop doing all the jobs. I'd like for it to be able to do more for me."
"There are other security technologies outside of this SIEM that should be inside of this SIEM. I can see in their roadmap that they're trying to address a lot of these things, and have these technologies built into the solution, because there is no point in going to another vendor or opening up a second window to obtain the data that you need."
"The SOAR capabilities need improvements as they currently require programming knowledge."
"We have run into problems with stability going through upgrade processes. Recently, we have been on the front edge of the upgrade path. When that happens we tend to run into issues either with certain functionality not working after the upgrades or stability issues because of the upgrades."
"The software needs to work on its pricing."
"The pricing is the only problem."
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"It's hard to find people who know how to use syslog-ng. I often find problems with configurations, and solutions aren't integrated correctly with syslog-ng. For example, there might be data with extra decimals, or the collector agents are incorrectly named. It isn't a problem with the solution; it's a lack of professionals."
"There is always the potential for additional integration and protocol extensions."
"The filtering has room for improvement."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"There is room for improvement in terms of observability."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
 

Pricing and Cost Advice

"Everything is expensive with LogRhythm, and you don't get anything for free."
"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."
"It is a very cost-effective solution."
"I would rate the tool's pricing around eight out of ten."
"The license cost is around $10 per MPS."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
