Featured Reviews

Laurentiu Popescu - PeerSpot reviewer
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

"ELK documentation is very good, so never needed to contact technical support."
"It is very quick to react. I can set it to check anomalies or suspicious behavior every 30 seconds. It is very fast."
"The most valuable features are the speed, detail, and visualization. It has the latest standards."
"It is scalable."
"The scalability is good. It can be scaled easily in the production environment."
"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."
"I use the stack every morning to check the errors and it's just so clear. I don't see any disadvantage to using Logstash."
"It can handle millions of loads at a time, and you can always use the filters to find exactly what you are looking for and detect errors in every log message you are searching for, basically."
"Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is the most mature solution in the market."
"Security Onion brings these tools together in one platform, making it easier to investigate security events and understand what's happening across the network."
"What I appreciate most about Security Onion is that it combines multiple security monitoring tools into one platform."
"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."
 

Cons

"The solution could offer better reporting features."
"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."
"There is an area of improvement in the Logs list. The load list may need to be paginated as there are limits."
"Email notification should be done the same way as Logentries does it."
"The tool should improve its scalability."
"Sometimes, the solution isn't the easiest to use."
"Elastic Security has a steep learning curve, so it takes some time to tune it and set it up for your environment. There are some costs associated with logging things that don't have value. So you need to be cautious to only log things that make sense and keep them around for as long as you need. You shouldn't hold onto things just because you think you might need them."
"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."
"The initial setup of the solution is a little bit difficult."
"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."
"The product is not easy to learn."
"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."
"Security Onion's user interface could be improved."
"One way Security Onion could improve is by making the initial setup and configuration easier, especially for new users."
"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."
 

Pricing and Cost Advice

"We use the open-source version, so there is no charge for this solution."
"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 tool's pricing is flexible and comes at unit cost. You don't have to pay for everything."
"We are using the free, open-source version of this solution."
"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."
"Affordable but with additional costs"
"Elastic Stack is an open-source tool. You don't have to pay anything for the components."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
"It is an open-source solution."
