We compared Graylog and LogRhythm SIEM based on our users' reviews in five categories. We reviewed all of the data, and you can find the conclusion below.
Features: Graylog stands out with its exceptional search functions, seamless integration with Elasticsearch, and real-time data access. Users praised LogRhythm SIEM for its user-friendly centralized dashboard, strong integration capabilities, and event-filtering capabilities. Graylog could benefit from additional customization options and an improved rule-creation process. LogRhythm SIEM has the potential to improve its SOAR and NDR features, platform stability, and MDI integration. LogRhythm users requested expanded log storage, better load balancing, and streamlined search capabilities.
Service and Support: Graylog's customer service is generally well-regarded, with reviewers noting effective solutions and satisfactory experiences. While response times may differ, Graylog's support is considered superior compared to that of other products. LogRhythm SIEM was generally praised for its helpful and knowledgeable support, although there have been occasional delays and knowledge problems.
Ease of Deployment: Some Graylog users said the setup was easy. Other reviewers faced challenges, but these were easily resolved with help from the vendor’s support staff. Graylog is easier to set up in smaller environments, but it could get complicated in large clusters. LogRhythm SIEM's setup is considered to be straightforward. However, it is more time-consuming and complex for enterprise deployments involving multiple components or vendors, and users often require assistance from professional services or LogRhythm-certified engineers.
Pricing: Graylog offers an enterprise edition and an open-source option with a daily capacity restriction. Some users said that data costs can be expensive. LogRhythm SIEM’s license typically includes all elements. However, enterprise customers may encounter complexities related to additional features and add-ons.
ROI: Graylog can offer some cost savings. The precise ROI may vary depending on the organization’s size and use case. LogRhythm SIEM has proven to be highly valuable, delivering a significant ROI by reducing the mean time to detect and respond.
"Open source and user friendly."
"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."
"The ability to write custom alerts is key to information security and compliance."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"We should be able to response to threats and gain visibility into our environment that we don't currently have."
"In terms of security, LogRhythm NextGen SIEM is great."
"The initial setup process is very user-friendly."
"Their customer support is friendly and willing to help."
"I would rate the product a ten out of ten. The solution is very user-friendly and straightforward. The tool's report customization is interesting."
"Overall effectiveness is very good. I like how it is oriented to both analysts and technical support people. It's easily adopted by end users as much as by technologists."
"It has allowed us to dive deeper into our network and figure out what is going on by parsing logs properly and being able to reduce the time it takes to work cases down from seven days to approximately two days."
"Technical support has always been helpful."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."
"More customization is always useful."
"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."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"Graylog can improve the index rotation as it's quite a complex solution."
"We've had issues with scaling and local support."
"I would like a more fuller implementation of STIX/TAXII so I can pull in some of the government lists without having to go implement a whole new STIX/TAXII platform."
"The log storage capacity should be increased."
"We would like to see more things out of the console into the web UI. I guess this is what they are doing in 7.4."
"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."
"Stability has probably been one area where Health Checks have not been great with the product. We have been told that they are going to improve Health Checks on product, though we do struggle with them on a daily basis."
"The solution is likely not the best option for a smaller organization."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
