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.

A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

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

Pros

"Elastic SIEM is pretty stable."
"We chose the product based on the ability to scan for malware using a malware behavioral model as opposed to just a traditional hash-based antivirus. Therefore, it's not as intensive."
"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."
"Elastic Security is cost-effective compared to Defender and CrowdStrike."
"The most valuable feature is the machine learning capability."
"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."
"My advice is that this is a good product to use if you are financially contained, and you want to start with something small."
"The stability of the solution is good."
"We use Security Onion for internal vulnerability assessment."
"Security Onion is the most mature solution in the market."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"We'd like better premium support."
"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."
"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."
"The solution could also use better dashboards. They need to be more graphical, more matrix-like."
"This type of monitoring is not very mature just yet. We need more real-time information in a way that's easier to manage."
"The biggest challenge has been related to the implementation."
"Email notification should be done the same way as Logentries does it."
"The price of this product could be improved, especially the additional costs."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
"The initial setup of the solution is a little bit difficult."
 

Pricing and Cost Advice

"Compared to other products such as Dynatrace, this is one of the cheaper options."
"The solution is not expensive and costs around ten dollars a month."
"Compared to other tools, Elastic Security is a cheaper solution."
"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."
"Elastic Stack is an open-source tool. You don't have to pay anything for the components."
"We are using the free, open-source version of this solution."
"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."
"I can say that the product is cheaply priced."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
"It is an open-source solution."
