Laurentiu Popescu - PeerSpot reviewer

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.

Provides good threat hunting by finding infected ports, but its initial setup is difficult
The most valuable feature of Security Onion for security monitoring is its ability to find infected ports. I have used the Squert tool within Security Onion the most for threat hunting The initial setup of the solution is a little bit difficult. I have been using Security Onion for one year.…

Quotes from Members

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

Pros

"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 helps improve the security posture of Pakistan through centralized visibility and real-time processing."
"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."
"The most valuable feature of Elastic Security is that you can install agents, and they are not separately licensed."
"It's very customizable, which is quite helpful."
"One of the most valuable features of this solution is that it is more flexible than AlienVault."
"The tool's functionality is good for overall security and incident response times."
"The visualization is very good."
"We use Security Onion for internal vulnerability assessment."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is the most mature solution in the market."
 

Cons

"The solution should generate an automatic product that integrates with ELK Stack to use artificial intelligence."
"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 could also use better dashboards. They need to be more graphical, more matrix-like."
"They don't provide user authentication and authorisation features (Shield) as a part of their open-source version."
"The training that is offered for Elastic is in need of improvement because there is no depth to it."
"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."
"If you compare this with CrowdStrike or Carbon Black, they can improve."
"Better integration with third-party APMs would be really good."
"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

"The solution is not expensive and costs around ten dollars a month."
"Compared to other products such as Dynatrace, this is one of the cheaper options."
"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."
"We use the open-source version, so there is no charge for this solution."
"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 can say that the product is cheaply priced."
"There is no charge for using the open-source version."
"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."
"It is an open-source solution."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
