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.
"Real-time UDP/GELF logging and full text-based searching."
"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"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."
"Open source and user friendly."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"LogRhythm does a very good job of helping SOCs manage their workflows."
"I would say the most valuable feature of LogRhythm is that it has built-in UEBA functionality, among other basic Windows packages."
"The Web Console is my favorite. It enables me, at a glance, to see the health of the environments."
"The dashboards in the LogRhythm SIEM really help us as a starting point. It gives us a starting point we can go to every day. We walk through several dashboards to see anomalous activity for further investigation."
"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."
"SOAR is integrated with the dashboard that we use for threat management. Because it's all integrated, it is useful for us when we deploy something on-prem."
"The most valuable feature of LogRhythm for me is the ability to correlate logs throughout many different log sources."
"We take in around 750 million logs a day. We have a lot of products and that would be a lot of different panes of glass that we would have to look through otherwise. By centralizing, we can triage and take steps much more quickly than if we tried to man that many interfaces that come with the products."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"Elasticsearch recommendations for tuning could be better. Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"There should be some user groups and an auto sign-in feature."
"Dashboards, stream alerts and parsing could be improved."
"The installation was a bit complex because we are running a virtual infrastructure."
"I would like to see our vulnerabilities counter. We will be using Tenable to fill that void right now."
"The initial setup is not so easy because it is quite a process."
"Scalability misses the mark sometimes, especially when you have an integrated disaster recovery built into the solution."
"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 really like to see some type of group or global management for RIM policies,"
"I would like to suggest that they should improve their usage of third party tools for making dashboards and reports. If they would create their own tools for dashboard and report, it would be much better in terms of security purposes."
"The web and on-premise console interface should be the same instead of having a separate engine for each."
