NC
Security Officer at JSC "Moldtelecom" S.A.
Log analysis has become clearer and faster but visualization and extensibility still need work
The problem was with the complexity and the cost to add extensions. We found this very expensive to buy another version with additional features. I think that Graylog Enterprise does not have customizable dashboards. I did not see them in Graylog Enterprise because most of the time we used the open source free version, which is limited. I think Graylog Enterprise should improve some things that they have in the paid version and perhaps provide users with a menu that gives examples of parsing logs and draws graphics so that people do not need to improve another system such as Grafana. This would be interesting. When it comes to functionalities, I found the log management in Graylog Enterprise acceptable. It is very simple to use and to collect logs. It has support for different protocols and different ports, and the sidecar is easy to use. However, in visualization, I think it needs to be much better.

Provides strong detection capabilities but requires improvements in parsing and stability
I cannot think of any specific features that LogRhythm SIEM can improve upon since it supports a wide variety of major vendors. However, they need to improve their parsing techniques; the tool should understand various devices and present data in a human-readable format. For example, if a personal Android mobile needs to be integrated, LogRhythm SIEM should be able to parse that data effectively. They also need to improve their database of supported devices to cover smaller vendors alongside the major players, allowing for better global reach and usability. I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.

Quotes from Members

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

Pros

"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"Graylog is very handy."
"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."
"I am very proud of how very stable the solution is."
"The ability to write custom alerts is key to information security and compliance."
"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"The most valuable features of the solution are network monitoring, user behavior analytics, and log collection."
"Its ability to work with all different sorts of log sources has been extremely valuable."
"The correlation engine is extremely valuable because it uses machine learning to process information from the central manager and identifies issues in the network."
"The GUI is very intuitive and the solution has good integration."
"The log analysis feature is valuable."
"LogRhythm has shown to us, to this point in time, that it has the capabilities of being able to deliver actionable intelligence to the security engineers and analysts."
"It has centralized monitoring for our security operations. Therefore, it improves our analysts' work."
"It's positively affected our overall rate of efficiency."
 

Cons

"The problem was with the complexity and the cost to add extensions."
"More customization is always useful."
"There should be some user groups and an auto sign-in feature.​"
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"With technical support, you are on your own without an enterprise license."
"Dashboards, stream alerts and parsing could be improved."
"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 complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"The initial setup is not so easy because it is quite a process."
"In terms of blind spots, we are looking for more improvements since we don't have visibility over everything."
"I face stability issues every quarter that necessitate corrective maintenance."
"Scalability misses the mark sometimes, especially when you have an integrated disaster recovery built into the solution."
"Granted, we haven't enabled the UEBA module, but we're forwarding all our proxy logs to LogRhythm and we have a really hard time pulling those proxy logs back out of LogRhythm. However, when we take LogRhythm and forward the same logs into somebody else's user-based analytics software, we get the majority of what we were missing... If we've got all our proxy logs and I go out to Google or Facebook or the like, we should be able to go in and pull that information out ten minutes later, but it's a big challenge to do that."
"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."
"Their ticketing system for managing cases can be improved. They can either do that or adopt some of the open-source ticket systems into theirs. The current system works and gets the job done, but it is very bare-bones and basic. There are some things that could be improved there. They should also bring in more threat intelligence into the product and also probably start to look into the integration of more cloud or SAS products for ingesting logs. They're doing the work, but with the explosion of COVID, a lot of businesses have started to move towards more cloud applications or SAS applications. There is a whole diverse suite of SAS products out there, which is a challenge for them and I get it. They seem to be focusing on the big ones, but it'll be nice to be able to, for example, pull in Microsoft logs from Office 365. They are working towards a better way of doing that, and they have a product in the pipeline to pull logs in from other SAS applications. The biggest thing for them is going to be moving away from a Windows Server infrastructure into a straight-up Linux, which is more stable in my eyes. For the backend, they can maybe move into more of an up-to-date Elastic search engine and use less of Microsoft products."
"It is a product that is very hard to use."
 

Pricing and Cost Advice

"We're using the Community edition."
"We are using the free version of the product. However, the paid version is expensive."
"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."
"Having paid official support is wise for projects."
"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."
"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."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"I use the free version of Graylog."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"I give the price a six out of ten."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"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."
"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."
