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

"The most valuable feature is the search function, which allows me to go directly to the target to see the specific line a customer is searching for."
"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."
"Overall, this product does what it is supposed to do, although there is always room for improvement."
"Just the ability to do a lot more than just up-down is nice, which a lot of people take for granted."
"It's not very complicated to install Elastic."
"The most valuable feature is the ability to collect authentication information from service providers."
"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."
"Overall, the product is very stable and it is well-liked."
"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

"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."
"This solution cannot do predictive maintenance, so we have to build our own modules for doing it."
"The price of this product could be improved, especially the additional costs. I would also like to see better-quality graphics."
"It is difficult to anticipate and understand the space utilization, so more clarity there would be great."
"Elastic Security could improve the documentation. It would help if they were more simple and clean."
"The solution could offer better reporting features."
"Anything that supports high availability or ease of deployment in a highly available environment would help to improve this solution."
"The training that is offered for Elastic is in need of improvement because there is no depth to it."
"The initial setup of the solution is a little bit difficult."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
 

Pricing and Cost Advice

"When compared to other products, the price is average or on the low side."
"The product offers an amazing pricing structure. Price-wise, the product is very competitive."
"We are using the free, open-source version of this solution."
"Compared to other tools, Elastic Security is a cheaper solution."
"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."
"I find it better than Splunk in terms of cost-effectiveness. For cost-effectiveness, I would rate it a nine out of 10."
"This is an open-source product, so there are no costs."
"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."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
"It is an open-source solution."
