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.

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

"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."
"It's open-source and free to use."
"I like that it's a SIEM platform. I like that I can sell Elastic Security quickly. Elastic Security has a large community that can support users."
"The most valuable feature for me is Discover."
"It is an extremely stable solution. Stability-wise, I rate the solution a ten out of ten."
"The most valuable features are the speed, detail, and visualization. It has the latest standards."
"The most valuable feature is the scalability. We are in Indonesia, more engineers understand Elastic Security here. So it is easier to scale and also develop. In features, the discovery to query all the logs is very important to us. It is very easy, especially with the query function and the feature to generate alerts and create tools. Sometimes we use the alert security dashboard to monitor our clients."
"The solution has a good community surrounding it for lots of helpful documentation for troubleshooting purposes."
"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."
"We use Security Onion for internal vulnerability assessment."
 

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."
"The tool should improve its scalability."
"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."
"Upgrades currently released as stacks when it should be a plugin or an extension to save removal and reinstallation."
"The tool needs to integrate with legacy servers. Big companies can have legacy servers that may not always be updated."
"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."
"Anything that supports high availability or ease of deployment in a highly available environment would help to improve this solution."
"There isn't really a very good user experience. You need a lot of training."
"The initial setup of the solution is a little bit difficult."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
 

Pricing and Cost Advice

"Compared to other tools, Elastic Security is a cheaper solution."
"We use the open-source version, so there is no charge for this solution."
"Elastic Security is free to use."
"When compared to other products, the price is average or on the low side."
"Compared to other products such as Dynatrace, this is one of the cheaper options."
"Its price is fine. Its licensing works on a yearly basis. We have to renew the license every year. I also have a good experience with Darktrace. When we buy Darktrace, we get training free of cost, which is not there in Elastic. We have to pay extra for training. There is certainly room for improvement."
"The solution is not expensive and costs around ten dollars a month."
"This is an open-source product, so there are no costs."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
"It is an open-source solution."
