Has provided reliable alerts and helped identify infrastructure issues through detailed reporting
The best features of CrowdStrike Observability include the way they show issues to the client or agent, and their data collection method is interesting because they use an agent-less approach in some cases, collecting data from infrastructure such as firewalls. Additionally, they have the agent, but the presentation in the management console is excellent as we have observability end-to-end with the servers and all the services configured in the use cases. The intelligent alerting feature is excellent and configured on our console, being highly effective as it detects real alerts and just warnings or real issues. Identifying performance bottlenecks is important because they collect numerous MD5 or hash keys including movements or playbooks. The way they organize that in the console is excellent, allowing you to have reports detecting issues, which not only includes detection but also provides solutions to those issues.

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.

Pros

"The intelligent alerting feature is excellent and configured on our console, being highly effective as it detects real alerts and just warnings or real issues."
"In the logs and the trajectory, it shows detailed information about where the source of infection comes from, how it travels, and how to reach there."
"CrowdStrike Observability offers strong predictive analytics capabilities, and the intelligent alerting system helps minimize noise and optimize IT resources effectively."
"The log aggregation and correlation of data are notable features that enhance our operations."
"The intelligence database provided by CrowdStrike is very impressive."
"CrowdStrike Observability is a signature-less solution where you don't need to update your endpoints or the CrowdStrike Observability agents regularly, and it is completely based on AI and ML search engines."
"The dashboard and user interface of CrowdStrike Observability are quite good, and the support is responsive."
"The price is worth it."
"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."
"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."
"We use Security Onion for internal vulnerability assessment."
 

Cons

"For reporting or log management, having a longer duration for backup without needing to purchase a paid subscription would be beneficial. Currently, there is a default ninety-day backup period."
"Technical support received a rating of 4 out of 10."
"The pricing is very high and small companies cannot afford it. They should reduce the price because the backend infrastructure is the same."
"From the different deployments I have worked with, the shortcomings of CrowdStrike Observability are often because of what clients are able to share with CrowdStrike."
"We had some difficulties at the beginning, but at this moment they are improving, so probably in some months I will give them a ten."
"Integration with Huawei should be more straightforward."
"The customer service is not satisfactory for me. The support is only available in English, and my users in LATAM regions such as Peru and Colombia require local language support, which is not currently provided."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
"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."
