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 Security helps improve the security posture of Pakistan through centralized visibility and real-time processing."
"It's not very complicated to install Elastic."
"The performance is good and it is faster than IBM QRadar."
"This is definitely a product that I recommend using."
"The solution has very good logging functionality, the aggregation capability is quite useful, the solution is quite stable, the performance has been good, and the solution scales well."
"It is the best open-source product for people working in SO, managing and analyzing logs."
"Based on my experience, it's quite easy and manageable with small scale implementations, and the time to market is quite fast."
"The feature that we have found the most valuable is scalability."
"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."
"Elastic sometimes does not correctly identify threats or anomalies. It might not classify an issue as malicious or critical accurately."
"One thing they could add is a quick step to enable users who don't have a solid background to build a dashboard and quickly search, without difficulty."
"I'm not satisfied with technical support because whenever you raise a case, it goes to some random support person who asks questions about the architecture."
"Configuring the server is difficult and can be improved."
"We're using the open-source edition, for now, I think maybe they can allow their OLED plugin to be open source, as at the moment it is commercialised."
"The solution's basic setup takes time, and a lot of effort is required from the beginning to make it actually work."
"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."
"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

"I find it better than Splunk in terms of cost-effectiveness. For cost-effectiveness, I would rate it a nine out of 10."
"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 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."
"Compared to other tools, Elastic Security is a cheaper solution."
"We are using the free, open-source version of this 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."
"I can say that the product is cheaply priced."
"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."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
"It is an open-source solution."
