Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.

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

"I see LogRhythm SIEM as value for money; I would rate it eight out of ten."
"The advanced intelligence engine, in fact the whole suite, is very powerful and as far as I’m concerned, it’s one of the best for security management."
"It has centralized monitoring for our security operations. Therefore, it improves our analysts' work."
"LogRhythm is scalable, it's robust, they're constantly growing it, their tech support is good, their Professional Services are good."
"We should be able to response to threats and gain visibility into our environment that we don't currently have."
"The web interface is awesome, it's very intuitive and gives a lot of great information."
"All in all, it's one of the best SIEMs, as a total package, that I've worked with."
"Its benefits are broad. The solution isn't necessarily made to do any one thing, but it can do anything you tell it to. It is able to tackle any different type or size of job."
"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."
"Syslog-ng has a separate config file in addition to the core configuration."
"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."
"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."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
 

Cons

"The integration is slightly difficult with other assets, like EDR technologies or firewalls."
"We are seeing performance issues with the appliance."
"One area for improvement in LogRhythm NextGen SIEM is that it's a Windows-based tool, and I feel it should be on the Linux operating system instead. Another area for improvement in the tool is the UI. There should be minor changes in the UI to make it better, though I like the dashboards in LogRhythm NextGen SIEM."
"I would like the log management database to perform more efficiently."
"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."
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"I face stability issues every quarter that necessitate corrective maintenance."
"I have Windows administrators who will remove the agent when they think that that's what's fouling up their upgrade or their install or their reconfiguration, etc. The first thing they do is to turn off the antivirus, turn down the firewall, and take off anything else. They don't realize that the LogRhythm agent is just sitting there monitoring. Most antivirus products have application protection features built-in where, if I'm an admin on a box, I can't uninstall antivirus. I need to have to the antivirus admin password to do that."
"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."
"The filtering has room for improvement."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"There is room for improvement in terms of observability."
"There is always the potential for additional integration and protocol extensions."
 

Pricing and Cost Advice

"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"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."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"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 product is inexpensive than other tools."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"The nice thing about LogRhythm is you can either use the agents, getting a certain number of agents with your license depending on how you want to go, and those agents do a lot of cool things, or you can use CIS Log host, then you have like an unlimited number of them."
"Syslog-ng is a free open-source solution."
"Syslog-ng is open-source."
