Featured Reviews

Laurentiu Popescu - PeerSpot reviewer
Chief Product Officer at ClusterPower
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.

Has ensured compliance by centralizing log data and supporting secure connections
We currently do not use that feature. We currently have just an open-source release, not a premium release. My boss has indicated that he wants to buy a premium syslog-ng version next month. I think we can use other features of this tool in the future. In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it.

Quotes from Members

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

Pros

"It can handle millions of loads at a time, and you can always use the filters to find exactly what you are looking for and detect errors in every log message you are searching for, basically."
"This is one of the best open-source log management and log analyzer tools in the world."
"The most valuable feature is the speed, as it responds in a very short time."
"Based on my experience, it's quite easy and manageable with small scale implementations, and the time to market is quite fast."
"Elastic Security makes data communication easier."
"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."
"This solution enables us to monitor application performance from Elasticsearch and we can predict some behaviors for applications using ELK."
"Elastic provides the capability to index quickly due to the reverse indexes it offers. This data is crucial as it contains critical information. The reverse index allows fast data indexing because of Elastic's efficient search engine."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"What I appreciate most about syslog-ng is its configuration; its C-style config is much easier to understand, read, and write than other popular solutions such as syslog or rsyslog."
"For us, the most valuable feature is the use of compound search for searching logs at a specific time, by a specific user, or specific behavior."
"Syslog-ng provides easy access to all my logs. It helps me show managers and other clients precisely where an incident occurred. I also like it because you can integrate syslog-ng with multiple solutions to allow real-time monitoring."
"We chose syslog-ng because it is easy to install, easy to maintain, easy to update, and due to the fact that all data arrive in raw format, we can manipulate it as we want."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"Syslog-ng has a separate config file in addition to the core configuration."
 

Cons

"I think because we are a cybersecurity company, the thing that can be improved is the prebuilt tools, especially quality. Compared to its competitor, they still have fewer prebuilt security rules. Elastic Security, in terms of generating alerts, cannot group the same products into one another. Even though the alerts are the same, they still generate them one by one. So, it is very noisy in our dashboard. I would like the Elastic Security admin to group all the same alarms into one alarm so that our dashboard is not noisy."
"Because of the notification issue we moved to Logentries, as it provides a simple way to get notification whenever a server encounters an error or something unexpected happens (which we have defined using Regex)."
"The solution's basic setup takes time, and a lot of effort is required from the beginning to make it actually work."
"There are connectors to gather logs for Windows PCs and Linux PCs, but if we have to get the logs from Syslog then we have to do it manually, and this should be automated."
"The training that is offered for Elastic is in need of improvement because there is no depth to it."
"There isn't really a very good user experience. You need a lot of training."
"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."
"The initial configuration and setup are complicated and not straightforward."
"The filtering has room for improvement."
"There is always the potential for additional integration and protocol extensions."
"It's hard to find people who know how to use syslog-ng. I often find problems with configurations, and solutions aren't integrated correctly with syslog-ng. For example, there might be data with extra decimals, or the collector agents are incorrectly named. It isn't a problem with the solution; it's a lack of professionals."
"There is room for improvement in terms of observability."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
 

Pricing and Cost Advice

"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."
"Compared to other tools, Elastic Security is a cheaper solution."
"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."
"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 solution is free."
"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."
"There is no charge for using the open-source version."
"We are using the free, open-source version of this solution."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
