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.

Centralized threat monitoring has improved visibility but demands complex setup and configuration

The best features Security Onion offers include acting as the intrusion detection system in my organization and helping me to address traffic, logs, and events happening within the organization. Since Security Onion is an open-source system that integrates with tools like Suricata and Zeek with the ELK stack, it enables threat detection and response capabilities, delivering high-level security measures at a cost, making it suitable for businesses of varying skill levels. These integrations with Suricata and Zeek have greatly impacted our workflow and our team's effectiveness by helping us address issues such as identifying intrusions, evaluating threats, and overseeing log files. This tool is very cost-effective, making it suitable for any size of organization wanting to use it.

Quotes from Members

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

Pros

"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."

"One of the main features that I like about LogRhythm NextGen SIEM is that there are a lot of pre-built pieces. Like with our AV, we didn't have to tell it how to read the logs; they already had it pre-made. So, we essentially just had to follow their guide to get the logs imported in and set up some rules for it. We've only had to manually create the parsing rules for a few of our vendors so that we could interpret the logs correctly. Most of them had already been pre-created for us."

"It has helped us centralize and have better visibility into devices on our network. We are better able to respond to threats in a timely manner."

"LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis."

"It makes it possible to stay aware of much more of what's going on; we get an overview, a macro view that we can zoom in on as opposed to prior to that when we had individual panes of glass and might be stuck in the firewall interface for half a day while something going on is not getting addressed that we really should probably investigate."

"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."

"This solution has been almost like a transformative change in how we detect and then respond to incidence."

"If I look back to my other SIEM solution providers, the one we had before this, it's light years difference."

More LogRhythm SIEM pros

"Security Onion has positively impacted my organization by greatly improving our security posture, making alert triage easier to handle, simplifying the analysis of threats, and decreasing the cost of threat analysis and detection."

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

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

"We use Security Onion for internal vulnerability assessment."

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

Cons

"When we had version 7.2.6, there were a lot of issues deploying that version and with the indexing. The indexer was unstable. So, we were not able to use the platform when we were on that version until we were able to upgrade to 7.3.4."

"I would probably look for more things to go into the web console that is currently on the fat client."

"Right now I know there's a big issue with reporting. It's challenging, at least for us, to do some of the reporting within the system itself."

"LogRhythm's SOAR and NDR features don't stack up well against competitors. maybe integrating theme functionality as the other do. But in general, it's okay."

"Sometimes, LogRhythm will parse the rule but perhaps it won't get every little detail out of the rule."

"It should be improved for automated setup and auto-configuration. There should be ease of integration and ease of setup."

"Setting up LogRhythm SIEM is complex. Everything is complicated — the activity, integration, and analysis."

"I'm not sure if I would recommend the solution to others as they still need to improve a few things."

More LogRhythm SIEM cons

"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."

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

"The product is not easy to learn."

"For Security Onion, setting up and configuring the system can be quite challenging for newcomers due to the need for a grasp of networking and security concepts."

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

Pricing and Cost Advice

"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."

"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."

"NextGen SIEM's pricing is moderate."

"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."

"I would rate the tool's pricing around eight out of ten."

"It is a very cost-effective solution."

"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."

"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."
