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

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."

"The intelligence of the system has been very impressive. It's not quite AI, but the technical bit where it correlates information, based on the seen attacks within an organization is good."

"The product has huge integration varieties available."

"Elastic Security is very customizable, and the dashboards are very easy to build."

"Elastic Security is very easy to adapt."

"The tool's functionality is good for overall security and incident response times."

"The most valuable feature is the ability to collect authentication information from service providers."

"Elastic Security makes data communication easier."

More Elastic Security pros

"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

"There isn't really a very good user experience. You need a lot of training."

"Elastic sometimes does not correctly identify threats or anomalies. It might not classify an issue as malicious or critical accurately."

"There is an area of improvement in the Logs list. The load list may need to be paginated as there are limits."

"The price of this product could be improved, especially the additional costs. I would also like to see better-quality graphics."

"Elastic has one problem. In the past, Elastic Security was free. Now, they currently only offer the basic license or a certain period of time."

"The initial configuration and setup are complicated and not straightforward."

"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 should generate an automatic product that integrates with ELK Stack to use artificial intelligence."

More Elastic Security cons

"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

"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."

"Compared to other products such as Dynatrace, this is one of the cheaper options."

"The solution is free."

"I can say that the product is cheaply priced."

"Elastic Stack is an open-source tool. You don't have to pay anything for the components."

"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."

"Compared to other tools, Elastic Security is a cheaper 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."

More Elastic Security pricing and cost advice

"Security Onion is an open-source solution."
