Featured Reviews

Ivan Kokalovic - PeerSpot reviewer
Facilitates backend service monitoring with efficient log retrieval and API flexibility
Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.
Mokhammad Rakhman - PeerSpot reviewer
User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.

Quotes from Members

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

Pros

"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"The ability to write custom alerts is key to information security and compliance."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"The solution's most valuable feature is its new interface."
"Open source and user friendly."
"I am very proud of how very stable the solution is."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"In terms of security, LogRhythm NextGen SIEM is great."
"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."
"Their customer support is friendly and willing to help."
"The most valuable feature of LogRhythm for me is the ability to correlate logs throughout many different log sources."
"The user interface is pretty good compared to other SIEM tools."
"The content in the community is very helpful and useful for new users."
"We use this solution to examine disparate log sources and provide a cohesive method to search for anomalous behavior."
"LogRhythm has increased productivity because all the tools that we need are in the web UI, allowing us to find threats on our network fast and efficiently."
 

Cons

"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"Lacks sufficient documentation."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"In the next release, I would certainly like to see more HIPAA compliance. I would also like to see more integration with Palo Alto Networks, particularly their Traps, which is their endpoint solution."
"I would really like to see some type of group or global management for RIM policies,"
"The software needs to work on its pricing."
"The responses provided by the cloud team are inefficient."
"I have probably submitted half a dozen log parser requests, and I keep finding more stuff that we need to keep an eye on that doesn't have a definition in LogRhythm."
"One thing we have mentioned to them before is that we'd like to be able to do searches, or drill-downs, directly from an alarm. When you click it and the Inspector tab slides out, that might be a good place to be able to click the host to search for the last 24 hours. I know the search is right there but it would be even nicer to just click that and then have an option to search something there."
"We have gone through a few versions which has caused a lot of instability. We have logged a lot of hours with professional services."
"The main problem I have with LogRhythm SIEM is its stability; the solution is not stable."
 

Pricing and Cost Advice

"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."
"We are using the free version of the product. However, the paid version is expensive."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."
"Having paid official support is wise for projects."
"I use the free version of Graylog."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"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."
"The product is inexpensive than other tools."
"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."
"It is a very cost-effective solution."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"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 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."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
