Real-time analysis, easy setup, and open source
We stopped using it for analytics because of its price, and at the moment, we are using it mostly for log centralization. If you use it with high traffic for analytical purposes, as well as for the logs, the infrastructure costs are unbelievable. Graylog is a great product backed by Elasticsearch as the storage and query engine. It is just an interface on top of Elasticsearch and some Elasticsearch management. The indexes that are kept in Elasticsearch are managed by Graylog software. Elasticsearch is a decent product, but it's very infrastructure-heavy. It requires lots of resources, and if you make a mistake with provisioning, you are likely to not get a cluster back. We had a couple of outages like that, and we hated that. So, we ended up over-provisioning resources just to avoid such situations from happening. If you have a whole team trying to fix the Graylog instance for two days, that's a bit too much. That may be my Norwegian take on it, but the engineering resources are expensive. It's better to just provision the infrastructure. Overall, the product is great, and the features are just fine, but the infrastructure cost is what is killing it. The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic. I'm not sure if they can improve the infrastructure cost with the way Elasticsearch is. If they keep using Elasticsearch, maybe there are some opportunities there, or they can support other backends with cheaper storage. They could have a different backend to replace Elasticsearch or do some tweaks to Elasticsearch to reduce the costs. There could be partial parsing of logs or parsing on demand so that when you write data through Graylog to Elasticsearch, it doesn't need to crunch in every detail requiring that much CPU.

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

"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"Message forwarding through the in-built module."
"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."
"The ability to write custom alerts is key to information security and compliance."
"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."
"Open source and user friendly."
"File Integrity Monitoring is really valuable because we have it set up on our core assets. This is one of the key features that I utilize. We also use it quite a lot for event management to do reporting."
"It's positively affected our overall rate of efficiency."
"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."
"The initial setup process is very user-friendly."
"We now have a central point of monitoring for all potential threats."
"The user interface is pretty good compared to other SIEM tools."
"LogRhythm SIEM offers advanced features such as AI engine modules, machine learning, and threat intelligence integration, which help reduce false positives. Advanced analytics streamlines incident response processes, enabling incident responders to prioritize and automate alerts."
"As a healthcare company, what we use it for is compliance, then to protect our data from exaltation."
 

Cons

"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"I would like to see some kind of visualization included in Graylog."
"There should be some user groups and an auto sign-in feature.​"
"Graylog can improve the index rotation as it's quite a complex solution."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"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."
"Scalability-wise, it's not that great."
"We've tried to work with a couple of engineering department guys there. We've called them and called them but we never hear anything back."
"Technical support could use a little work in the terms of responding back. The feedback that we received is they do need a little more staff."
"I would really love to be able to take some of the data and not have to export it to a CSV file, so I can pull it into Excel to turn it into some other kind of graph."
"The product's stability needs improvement."
"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."
"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."
"The web and on-premise console interface should be the same instead of having a separate engine for each."
 

Pricing and Cost Advice

"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"It's an open-source solution that can be used free of charge."
"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."
"We're using the Community edition."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"I use the free version of Graylog."
"We are using the free version of the product. However, the paid version is expensive."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"The setup and licensing for small and medium size businesses is straightforward, though when it comes to the enterprise it pays to keep in mind the possibility for complications given all the extras and add-ons that may be required."
"We have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."
"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."
"NextGen SIEM's pricing is moderate."
"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."
