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.

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

"One of the most valuable features of this solution is that it is more flexible than AlienVault."
"Elastic Security actually has a very good cost-benefit ratio compared to other vendors in the market."
"The product has huge integration varieties available."
"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 Security is cost-effective compared to Defender and CrowdStrike."
"The indexes allow you to get your results quickly. The filtering and log passing is the advantage of Logstash."
"ELK Logstash is easy and fast, at least for the initial setup with the out of box uses."
"Elastic Security offers advanced features such as machine learning and integration with ChatGPT."
"Security Onion is the most mature solution in the market."
"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."
 

Cons

"Elastic Security could improve the documentation. It would help if they were more simple and clean."
"I would like more ways to manage permissions and restrict access to certain users."
"It could use maybe a little more on the Linux side."
"We had issues with scalability. Logstash was not scaling and aggregation was getting delayed. We moved to Fluentd making our stack from ELK to EFK."
"Email notification should be done the same way as Logentries does it."
"Their visuals and graphs need to be better."
"We set up a cron job to delete old logs so that we wouldn't hit a disk space issue. Such a feature should be available in the UI, where old logs can be deleted automatically. (Don’t know if this feature is already there)."
"Elastic Security consumes a lot of resources, requiring a substantial deployment setup."
"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 product offers an amazing pricing structure. Price-wise, the product is very competitive."
"Elastic Stack is an open-source tool. You don't have to pay anything for the components."
"The solution is free."
"I can say that the product is cheaply priced."
"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."
"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."
"It is an open-source solution."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
