Gajewski Marek - PeerSpot reviewer
Provides good anomaly detection and connectivity reporting
We previously used Splunk but switched to Elastic Security because Splunk was more expensive. Feature-wise, both tools are pretty much the same. They have almost the same functions. Elastic Security has a much better AI assistant that allows you to ask questions like a normal person. With Elastic Security, I can also predict the price and how much it will cost. Splunks's pricing depends on how much data we use and the different add-ons I have to add. The pricing is much better with Elastic Security.
Andrey Mostovykh - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"The most valuable thing is that this solution is widely used for work management and research. It's easy to jump into the security use case with the same technology."
"ELK documentation is very good, so never needed to contact technical support."
"Elastic Security offers advanced features such as machine learning and integration with ChatGPT."
"It's open-source and free to use."
"Elastic has a lot of beats, such as Winlogbeat and Filebeat. Beats are the agents that have to be installed on the terminals to send the data. When we install beats or Elastic agents on every terminal, they don't overload the terminals. In other SIEM solutions such as Splunk or QRadar, when beats or agents are installed on endpoints, they are very heavy for the terminals. They consume a lot of power of the terminals, whereas Elastic agents hardly consume any power and don't overload the terminals."
"The most valuable feature is the ability to collect authentication information from service providers."
"The most valuable feature is the scalability. We are in Indonesia, more engineers understand Elastic Security here. So it is easier to scale and also develop. In features, the discovery to query all the logs is very important to us. It is very easy, especially with the query function and the feature to generate alerts and create tools. Sometimes we use the alert security dashboard to monitor our clients."
"I like that it's a SIEM platform. I like that I can sell Elastic Security quickly. Elastic Security has a large community that can support users."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"I am very proud of how very stable the solution is."
"The ability to write custom alerts is key to information security and compliance."
"Message forwarding through the in-built module."
"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."
"The solution's most valuable feature is its new interface."
"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."
 

Cons

"Improvements in Elastic Security could include refining and normalizing queries to make them more user-friendly, enhancing the user experience with better documentation, and addressing any latency issues."
"We'd like to see some more artificial intelligence capabilities."
"Authentication is not a default in Kibana. We need to have another tool to have authentication and authorization. These two should be part of Kibana."
"Its documentation should be a bit better. I have to spend at least a couple of hours to find the solution for a simple thing. When we buy Elastic, training is not included for free with Elastic. We have to pay extra for the training. They should include training in the price."
"There should be a simulation environment to check whether my Elastic implementation is functioning perfectly fine. Other solutions have their own Android and iOS applications that I can install on my mobile so that I am continuously connected to the SIEM."
"Elastic sometimes does not correctly identify threats or anomalies. It might not classify an issue as malicious or critical accurately."
"If you compare this with CrowdStrike or Carbon Black, they can improve."
"Elastic Security's maintenance is hard and its scalability is a challenge. There are complications in scaling and upgrading. The solution needs to also provide periodic upgrade checks."
"With technical support, you are on your own without an enterprise license."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"There should be some user groups and an auto sign-in feature.​"
"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."
"Graylog can improve the index rotation as it's quite a complex solution."
"I would like to see some kind of visualization included in Graylog."
"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-"
 

Pricing and Cost Advice

"Elastic Stack is an open-source tool. You don't have to pay anything for the components."
"There is no charge for using the open-source version."
"The price is reasonable. It probably costs the same as ArcSight and LogRhythm SIEM. FortiSIEM might cost less than Elastic Security. There are no hidden or additional costs."
"The licensing cost of Elastic Security is based on the daily ingestion rate. I can't recall the exact figure, but for 10GB of log action daily, it would cost around $20,000."
"I find it better than Splunk in terms of cost-effectiveness. For cost-effectiveness, I would rate it a nine out of 10."
"The tool's pricing is flexible and comes at unit cost. You don't have to pay for everything."
"I can say that the product is cheaply priced."
"The pricing is in the middle. I think it is not an expensive experience if we compare it with big names, for example, QRadar, and also Oxide. I think Elastic Security is quite cheap. I would rate the pricing of this solution a five out of ten."
"We are using the free version of the product. However, the paid version is expensive."
"I use the free version of 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."
"We're using the Community edition."
"It's an open-source solution that can be used free of charge."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"Having paid official support is wise for projects."
"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."
