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 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 solution's most valuable feature is its new interface."
"Message forwarding through the in-built module."
"I like the correlation and the alerting."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"The ability to investigate a particular period of time where you can analyze logs is its most valuable feature."
"The major feature of this solution is its easy configuration which helps different team members to work on it effectively. This kind of feature is not available in other solutions because of a request for specialised schemes for configuration report extraction and searching. Another feature that I really admire is the significant improvement in the compliance in the auditing process by the solution. Our organisation-specific complaints require where the mailbox data needs to be forwarded, stored and searchable for a certain time period. This solution categorises data based on different types, which include cold, warm and hot data. These features allow faster and easier extraction of any data even if the event was occurring several years ago. I also like other features, especially user behaviour analysis and automation. If suddenly someone accesses your side or an unusual traffic is recorded from a user the solution flags it very effectively."
"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."
"It seems like it will scale easily with the way our environment is set up."
"Currently, we are in the implementation phase. LogRhythm is better than QRadar from the point of view of collecting Windows events. It has a much higher view. You can enable monitoring by default."
"LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis."
"NextGen SIEM's best feature is how it presents logs."
"We have to be able to show the evidence, and LogRhythm does a great job of putting it forward and making it easy to create reports with nice looking dashboards, which show off what we are doing as a security program."
 

Cons

"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."
"Lacks sufficient documentation."
"With technical support, you are on your own without an enterprise license."
"When it comes to configuring the processing pipeline, writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work."
"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 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."
"More customization is always useful."
"I would like to see some kind of visualization included in Graylog."
"When we originally got LogRhythm, their tech support was fantastic, and I loved them. Now, we don't quite get as quick of a response. I've been disappointed in the more recent tech support. When you call in, they'll say that they will get you somebody, and you'll finally get someone who will contact you back a day or so later. Whereas before, I would get help right away."
"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."
"It is a product that is very hard to use."
"The software needs to work on its pricing."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
"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."
"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."
"More help and assistance with some of the open source products, everything seems to be focused on Windows versus giving some guidance and some documentation on how to use it."
 

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."
"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."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"We're using the Community edition."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"We are using the free version of the product. However, the paid version is expensive."
"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 product is inexpensive than other tools."
"I would recommend that whatever sales quotes to them upfront, they will probably go up. Because they are probably going to outgrow that very quickly or once they start getting everything into it, they are going to have to move up anyway."
"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."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"The license cost is around $10 per MPS."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
