Cyber Security Lead at Orange

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.

Hands-on monitoring has built my threat detection skills and now supports my graduate research

The biggest challenges I have experienced with Security Onion are the learning curve and resource requirements, as it is not necessarily something you can install and immediately understand without networking and Linux knowledge. I actually encountered an HTTP 500 error with the management interface recently, which required troubleshooting and expanding my storage, showing me how important storage planning and system maintenance are when running Security Onion. What I would improve about Security Onion is probably the documentation around troubleshooting common issues, particularly storage management, and making the interface more approachable for new users. Having documentation of what works best would help, especially since you can have nodes or have it all built-in one as a standalone. If you use nodes, you have to have several different Security Onion instances downloaded, then have a manager and connect all of them together.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The solution is free."

"The solution's most valuable features are anomaly detection and connectivity reporting."

"It is an extremely stable solution. Stability-wise, I rate the solution a ten out of ten."

"It's simple and easy to use."

"Overall, the solution is good."

"Elastic Security is very easy to adapt."

"The indexes allow you to get your results quickly. The filtering and log passing is the advantage of Logstash."

"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."

More Elastic Security pros

"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."

"Security Onion has positively impacted my organization by enabling students to analyze logs, understand network traffic, comprehend intrusion detection, and utilize threat hunting and incident response skills in a practical environment, which are best practices we have implemented with the students."

"Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."

"What I appreciate most about Security Onion is that it combines multiple security monitoring tools into one platform."

"Security Onion brings these tools together in one platform, making it easier to investigate security events and understand what's happening across the network."

"Security Onion is the most mature solution in the market."

Cons

"Technical support could respond faster."

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

"It would be better if Elastic Security had less storage for data. My customers do not like this. Other vendors have local support in different countries, but Elastic Security doesn't. I would like to have Operational Technology (OT) security in the next release."

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

"The solution could also use better dashboards. They need to be more graphical, more matrix-like."

"We'd like to see some more artificial intelligence capabilities."

"There is room for improvement in the Kibana dashboard and in the asset management for the program."

"Because of the notification issue we moved to Logentries, as it provides a simple way to get notification whenever a server encounters an error or something unexpected happens (which we have defined using Regex)."

More Elastic Security cons

"One way Security Onion could improve is by making the initial setup and configuration easier, especially for new users."

"One of the improvements for Security Onion could be to address the issue of many logs and false positive alerts by reducing the number of false positives, as storage management is very hard sometimes due to a lack of storage space for logs, and they could implement methods to expand storage."

"The biggest challenges I have experienced with Security Onion are the learning curve and resource requirements, as it is not necessarily something you can install and immediately understand without networking and Linux knowledge."

"Security Onion can be made easier to set up initially, as it is somewhat difficult at the start, but once configured, it becomes a great tool to use."

"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

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

"We use the open-source version, so there is no charge for this solution."

"I find it better than Splunk in terms of cost-effectiveness. For cost-effectiveness, I would rate it a nine out of 10."

"Elastic Security is free to use."

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

"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."

"The product offers an amazing pricing structure. Price-wise, the product is very competitive."

"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."
