Has improved threat detection with deep log analysis and streamlined investigation workflows
The most useful features I find in Elastic Security are the forensic ones that allow us to carry deeper analysis into the logs for in-depth investigations, and the dashboards, with the reporting dashboard being quite user-friendly. Elastic Security is quite good at identifying threats, as it is part of the deep investigation tool that I mentioned before. Unless we need to look further into a certain log, we can carry out a deeper analysis and forensics on those particular logs. I can assess the impact of Elastic Security's real-time data analysis on our threat response efficiency as working pretty good. We are looking for real-time analysis because we have a continuous inflow of logs from different sources: from our cloud, from Active Directory, from our network. So it works pretty well.

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.
SumitKumar20 - PeerSpot reviewer

Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.

Quotes from Members

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

Pros

"I use the stack every morning to check the errors and it's just so clear. I don't see any disadvantage to using Logstash."
"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."
"It is an extremely stable solution. Stability-wise, I rate the solution a ten out of ten."
"Elastic Security is very customizable, and the dashboards are very easy to build."
"ELK Logstash is easy and fast, at least for the initial setup with the out of box uses."
"The most valuable feature is the machine learning capability."
"The tool's functionality is good for overall security and incident response times."
"This solution helps us because we can find all of the logs in one place."
"I know that there are other similar tools available, but I enjoy using Graylog the most."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"The best feature of Graylog is the Elasticsearch integration; we can integrate and run filters, such as an event of interest, and those logs we can send to any SIEM tool or use as analytics, and 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."
"The ability to write custom alerts is key to information security and compliance."
"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 centralized logs where one can find bugs quicker and find the line of code that is a problem has made us more efficient."
"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."
"LogRhythm really helps with our cybersecurity exposure because it gives us insights to make us more proactive versus reactive regarding events happening in our environment."
"LogRhythm is scalable, it's robust, they're constantly growing it, their tech support is good, their Professional Services are good."
"The product was easy to deploy and easy to learn how to use, and the web console is the best I have seen when compared to other SIEMs."
"The ability to investigate a particular period of time where you can analyze logs is its most valuable feature."
"The security operation center is excellent."
"We just had a great experience all round, and when comparing feature sets, the web interface to the alarm drill downs, the AI Engine drill downs, to the network monitor product, it was definitely on the top of the list."
"When it comes to dealing with support, all my interactions have been great. Everyone has known what they're doing and have been quick to respond."
"We have seen a measurable decrease in the mean time when detecting and responding to threats."
 

Cons

"They don't provide user authentication and authorisation features (Shield) as a part of their open-source version."
"The solution could also use better dashboards. They need to be more graphical, more matrix-like."
"It's a little bit of a learning curve to understand the logic of searching for things and trying to find what you're looking for in Elastic Security."
"The solution should generate an automatic product that integrates with ELK Stack to use artificial intelligence."
"We'd like better premium support."
"If the documentation were improved and made more clear for beginners, or even professionals, then we would be more attracted to this solution."
"An area for improvement in Elastic Security is the pricing. It could be better. Right now, when you increase the volume of logs to be collected, the price also increases a lot."
"The solution could also use better dashboards. They need to be more graphical, more matrix-like."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"The initial setup was really complex because I did it myself."
"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."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"More customization is always useful."
"The technical support is a weak point in this product. It's not so easy to contact them and they don't answer immediately."
"Lacks sufficient documentation."
"There should be some user groups and an auto sign-in feature.​"
"We would like to see a better base templates for reporting."
"My main thing I'd like to see is, when you're using canned reports, that they're not blank."
"The installation was a bit complex because we are running a virtual infrastructure."
"When we had version 7.2.6, there were a lot of issues deploying that version and with the indexing. The indexer was unstable. So, we were not able to use the platform when we were on that version until we were able to upgrade to 7.3.4."
"In terms of improvement, their community boards, where to go find things, as a customer. As they're growing and they're moving stuff around, it would be nice if we knew exactly where to find what."
"More features that I would like to see more development in are the automation and the smart response."
"One thing we have mentioned to them before is that we'd like to be able to do searches, or drill-downs, directly from an alarm. When you click it and the Inspector tab slides out, that might be a good place to be able to click the host to search for the last 24 hours. I know the search is right there but it would be even nicer to just click that and then have an option to search something there."
"We would like to see more things out of the console into the web UI. I guess this is what they are doing in 7.4."
 

Pricing and Cost Advice

"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, open-source version of this solution."
"We use the open-source version, so there is no charge for this solution."
"Elastic Security is free to use."
"Affordable but with additional costs"
"I can say that the product is cheaply priced."
"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."
"Compared to other tools, Elastic Security is a cheaper solution."
"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 are using the free version of the product. However, the paid version is expensive."
"It's an open-source solution that can be used free of charge."
"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."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"We're using the Community edition."
"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 use the free version of Graylog."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"The license cost is around $10 per MPS."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"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 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."
"NextGen SIEM's pricing is moderate."
"It costs a great amount, but its pricing is competitive with some of the other vendors. For licensing and support, we pay about 20,000. There are no additional costs or anything like that."
"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."
