A solid SIEM solution that should improve technical support and online resources to be easier to use
A big problem with the product is that we don't have much professional experience in Israel installing, implementing, and integrating this product. There is not enough of a knowledge base. There is no support for this product in this country, so problems have to be resolved through global technical teams. We like to work locally because of the language, and when the product is only supported outside the country, it's a little difficult to implement and use this product. Moreover, AI is something that must be added immediately. Artificial intelligence is a part of the competitors' products, and it's not been implemented for us.

Centralized threat monitoring has improved visibility but demands complex setup and configuration
The best features Security Onion offers include acting as the intrusion detection system in my organization and helping me to address traffic, logs, and events happening within the organization. Since Security Onion is an open-source system that integrates with tools like Suricata and Zeek with the ELK stack, it enables threat detection and response capabilities, delivering high-level security measures at a cost, making it suitable for businesses of varying skill levels. These integrations with Suricata and Zeek have greatly impacted our workflow and our team's effectiveness by helping us address issues such as identifying intrusions, evaluating threats, and overseeing log files. This tool is very cost-effective, making it suitable for any size of organization wanting to use it.

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 really scalable for the high-end power, enterprise customer."
"The most valuable features are its ingestion of logs and raising of alerts based on those logs."
"It's fully scalable. There is no limit. Of course, the license limits per day the number of terabytes. In my opinion, it's very flexible."
"I can have enterprise security, email security, next generation firewall security log, HIDS and NIDS logs, etc. all on the same dashboard. It makes it easy to pinpoint or correlate our server to this. I can find out if there is lateral movement. This is the biggest advantage of this solution."
"Performance and reporting are very good."
"Over time, NetWitness Logs and Packets has matured from a boxed solution with multiple parts to the current, more streamlined version for which we only need the software license to put it up on our own cloud and deliver it to multiple clients."
"The product's initial setup phase was not at all difficult."
"It's quite economical compared to other solutions in the market."
"Security Onion is the most mature solution in the market."
"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 has positively impacted my organization by greatly improving our security posture, making alert triage easier to handle, simplifying the analysis of threats, and decreasing the cost of threat analysis and detection."
"We use Security Onion for internal vulnerability assessment."
 

Cons

"RSA NetWitness Logs and Packets can improve the threat level aspect, it is lacking compared to other solutions."
"Lots of competing products have vulnerability protection built into their products, and this solution would be improved by including that support."
"I'd like to see improvement in its ease of use. It's basically unusable. It's overly complex."
"The system architecture is complex and sometimes it’s hard to troubleshoot potential problems."
"RSA NetWitness Logs and Packets can improve the threat level aspect, it is lacking compared to other solutions. Whenever any hacking activity or any other threat factor occurred they used to provide the coverages very fast when comparing RSA NetWitness Logs and Packets. I heard the other three solutions, from a discussion with my team members who had experience in other solutions, they used to say that. Whenever any issues happened across the globe RSA NetWitness Logs and Packets are a little bit slow improving those detection mechanisms."
"Cross Platform Integration could be improved."
"The multi-tenant capabilities are lagging compared to IBM QRadar."
"It is not so easy to customize this product."
"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."
"For Security Onion, setting up and configuring the system can be quite challenging for newcomers due to the need for a grasp of networking and security concepts."
"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

"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"We have yearly licensing costs. The license fee can be based on the volume of EPS. Some organizations may have, as a gentlemanly gesture, 10,000 EPS and get a 3,000 EPS license but actually use 5,000 EPS."
"Our license is for one year."
"This is a pricey solution; it's not cheap."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"The licenses are good but the cost is very expensive."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."
"It is an open-source solution."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
