Seamless SIEM Integration with Stellar Support **Rating:** 5.0/5.0 stars **Reviewed by:** Erik P. | Security Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** May 03, 2026 **What do you like best about Open XDR Security Operations Platform?** I use Open XDR Security Operations Platform as a SIEM. It aggregates and correlates logs from our different security solutions in one place, which is incredibly helpful for acting on them accordingly. I really like their implementation team; they can basically integrate any security solution with Open XDR Security Operations Platform. They develop parsers for different security solutions, and integrating them is a breeze. The initial setup was very easy, thanks to the presales team who helped us get to know the platform very quickly. **What do you dislike about Open XDR Security Operations Platform?** GUI could be improved by the standards of material design **What problems is Open XDR Security Operations Platform solving and how is that benefiting you?** It aggregates and correlates logs from different security solutions in one place, enabling us to act accordingly. ### 2. Comprehensive and unified platform for streamlined security operations **Rating:** 5.0/5.0 stars **Reviewed by:** Clem C. | SOC Analyst L1, Mid-Market (51-1000 emp.) **Reviewed Date:** August 10, 2024 **What do you like best about Open XDR Security Operations Platform?** As an SOC Analyst, I use the Open XDR Security Operations Platform daily to monitor, investigate, and respond to security incidents. What I like best is how it consolidates multiple data sources into a single, unified view. Instead of switching between different tools for endpoint, network, and cloud telemetry, I can correlate everything in one dashboard. This saves significant time during investigations and reduces alert fatigue. The automated correlation engine is particularly valuable. It highlights relationships between alerts and helps prioritize true threats over noise. The built-in playbooks for response automation also make incident handling faster and more consistent. For example, I can automatically isolate a compromised endpoint or enrich alerts with threat intelligence without manual effort. **What do you dislike about Open XDR Security Operations Platform?** The main drawback is that the initial setup and integration phase can take time, especially when connecting multiple third-party tools. Some dashboards can also feel slightly cluttered until they’re customized to match your team’s workflow. Despite this, once configured, the platform runs smoothly and significantly improves visibility and response efficiency. **What problems is Open XDR Security Operations Platform solving and how is that benefiting you?** Before implementing Open XDR, our team relied on separate systems for endpoint detection, network monitoring, and threat intelligence. This caused delays in correlating alerts and made it difficult to get a complete picture of incidents. With Open XDR, we now have centralized visibility and automated alert correlation, which cut investigation time by around 40 percent. It also reduced the number of false positives and improved our mean time to respond. Overall, Open XDR Security Operations Platform has become a core part of our SOC workflow. It enhances collaboration, improves accuracy in detections, and allows analysts to focus on real threats instead of manual data gathering. ### 3. SIEM with 360 visibility and Vendor Agnostic **Rating:** 5.0/5.0 stars **Reviewed by:** Jose Maria M. | SOC Analyst L1, Small-Business (50 or fewer emp.) **Reviewed Date:** October 10, 2025 **What do you like best about Open XDR Security Operations Platform?** The thing I like best about Stellar Cyber is its ability to integrate a variety of connectors. There has been an instance where there are hesitations regarding its compatibility with what we used. But those were not an issue with this platform. Custom alerts and filters are also great because it gives us a more refined visibility on what's needed to focus on. It is also easy to implement and pretty straightforward. The dashboard is great for beginners because you can easily understand what you see. It doesn't look super technical unlike the other platforms related to Stellar Cyber. **What do you dislike about Open XDR Security Operations Platform?** There are some bugs that makes it quite troublesome to use such as alerts that are already done and sometimes gets involved with the recent alerts when you're doing a bulk assignments. I figured that some workarounds for this is to uncheck the bulk assignments and redo the process. That way only the recent alerts will get involved. There are some cases that pop-up sometimes but no alerts generated but those are still bearable. Aside from these, the platform is great. **What problems is Open XDR Security Operations Platform solving and how is that benefiting you?** Inbound and outbound traffic analysis is really important for us. Having a platform that helps with the detection and showing related alerts greatly helps us understand what action we need to make. This will lead to a more proactive actions to prevent further malicious activities from occurring. User behavior is also required as much. People within the organization might not be very attentive with the way they act on the internet. Some of user's actions intentionally or not can become a risk that can compromised not only their accounts, devices but also the assets within the same network. That is what we are looking to prevent. The visibility for all those activities provided by Stellar Cyber greatly helps. ### 4.
