Featured Reviews

SyedAli17 - PeerSpot reviewer
Centralized monitoring improves security posture through rapid data processing
The processing part of Elastic Security is very interesting for us since we handle almost 7,000 to 8,000 alerts per minute. We require rapid processing speed for alerts and event data, and Elastic Security is very efficient at handling this level of data. Additionally, Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing.
Ivan Kokalovic - PeerSpot reviewer
Facilitates backend service monitoring with efficient log retrieval and API flexibility
Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

Quotes from Members

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

Pros

"The solution has a good community surrounding it for lots of helpful documentation for troubleshooting purposes."
"Elastic Security is very customizable, and the dashboards are very easy to build."
"The most valuable feature for me is Discover."
"Elastic Security is cost-effective compared to Defender and CrowdStrike."
"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 solution is compatible with the cloud-native environment and they can adapt to it faster."
"What customers found most valuable in Elastic Security feature-wise is the search capability, in particular, the way of writing the search query and the speed of searching for results."
"The visualization is very good."
"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."
"The product is scalable. The solution is stable."
"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."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"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."
"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
 

Cons

"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."
"With Elastic, you have to build the use cases for the specific requirement. Other products have a simple integration and more use cases to integrate out-of-the-box solutions for SIEM."
"Elastic sometimes does not correctly identify threats or anomalies. It might not classify an issue as malicious or critical accurately."
"It is difficult to anticipate and understand the space utilization, so more clarity there would be great."
"It could use maybe a little more on the Linux side."
"The solution needs to be more reactive to investigations. We need to be able to detect and prevent any attacks before it can damage our infrastructure. Currently, this solution doesn't offer that."
"The problem with ELK is it's difficult to administer. When you have a problem, it can be very, very difficult to rebuild indexes."
"One limitation of Elastic Security is that it does not have built-in workflows for all tasks. For example, if you need a workflow for compliance, you will need to create a custom workflow."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"With technical support, you are on your own without an enterprise license."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"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."
"Graylog can improve the index rotation as it's quite a complex solution."
"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."
 

Pricing and Cost Advice

"We are using the free, open-source version of this solution."
"Compared to other products such as Dynatrace, this is one of the cheaper options."
"The tool's pricing is flexible and comes at unit cost. You don't have to pay for everything."
"The solution is not expensive and costs around ten dollars a month."
"This is an open-source product, so there are no costs."
"It is easy to deploy, easy to use, and you get everything you need to become operational with it, and have nothing further to pay unless you want the OLED plugin."
"The base product is open-source but if you need advanced security features then you need to pay for the subscription. Elastic Security's price is reasonable in some cases and in other cases it's not."
"Affordable but with additional costs"
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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."
"Having paid official support is wise for projects."
"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."
"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."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"It's an open-source solution that can be used free of charge."
