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.

Real-time incident detection and user-friendly dashboard benefit daily operations
There are many types of AI, and this AI is very limited in SQL and features. There may be potential for improvement. So far, it seems very limited. It shows some good features in the correlation part, but I think there is room for improvement. For instance, when creating rules, it can suggest more rules, reducing the effort needed. If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules. Sometimes logs I receive don't mean anything, and I need technical stakeholders to share or forward logs, but these are sometimes inadequate. Keywords can help identify insufficient logs. I often lack time to verify logs. Sharing false positive results could be reduced to help my team.

Quotes from Members

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

Pros

"The solution's most valuable feature is its new interface."
"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."
"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."
"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."
"I like the correlation and the alerting."
"Real-time UDP/GELF logging and full text-based searching."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"We run 65 servers globally with just two people: an engineering person and me."
"Provided that the report is prebuilt and I can find what I am looking for, the reporting is the most valuable feature in this solution."
"It is very stable. We have not faced interruptions in the past four and a half years."
"The threat protection network is the most valuable feature, because when you get an offense, you can actually trace it back to where it originated from, how it originated, and why."
"It showed us where weaknesses were in our environment, so we could actively target those patches first."
"IBM Qradar's ability to simplify the number of events, not only on a technical level but by making that information easy to pan through the orchestration deduplication. It is very impressive given that we have hundreds of devices that send event logs through."
"When it comes to QRadar, they can do the correlation and not only in networks but also endpoints. This is one of the good features that we have noticed."
"It is a very optimized engine."
 

Cons

"With technical support, you are on your own without an enterprise license."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"Dashboards, stream alerts and parsing could be improved."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"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."
"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."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"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."
"The modularity could be improved."
"Whenever we are upgrading or installing any type of patch, at that time we have some delays."
"We have had problems with networking."
"QRadar needs a lot of fine tuning"
"The whole process for support is something that needs to be improved."
"I have noticed the interface has room for improvement."
"There is a lot of manual configuration required in order for the product to run smoothly, and I think that it could be made more automatic."
"They should speed up the incident response and also, at the same time, reduce the amount of manual effort that is required."
 

Pricing and Cost Advice

"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."
"​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."
"It's an open-source solution that can be used free of charge."
"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."
"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."
"We're using the Community edition."
"The cost of this product is expensive."
"There is a license required for this solution."
"The pricing needs to be such that they are more competitive with other vendors."
"IBM Security QRadar is a very expensive tool."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate IBM Security QRadar's pricing a five out of ten."
"IBM's Qradar is not for small companie. Unfortunately, it would be 'overkill' to place it plainly. The pricing would be too much."
"There is a license required for this solution. There are some limitations depending on what license you purchase."
"It is overly expensive and overly complex in terms of licensing. They have many different appliances, which makes it extremely difficult to choose the technology. It is very difficult to choose the technology or QRadar components that you should be deploying. They have improved some of it in the last few years. They have made it slightly easy with the fact that you can now buy virtual versions of all the appliances, which is good, but it is still very fragmented. For instance, on some of the smaller appliances, there is no upgrade path. So, if you exceed the capacity of the appliance, you have to buy a bigger appliance, which is not helpful because it is quite a major cost. If you want to add more disks to the system, they'll say that you can't."
