Room For Improvement

CrowdStrike Falcon SIEM needs better dashboards, automation, storage, licensing flexibility, and more cat-themed threat actor integrations.
Microsoft Sentinel needs enhancements in integration, usability, performance, automation, and cost management to better serve users and organizations.
An agent that advises me or notifies me what changes have happened since my last login to the platform, what has changed, what errors it has detected, what connector or parsing failures there have been, and that it gives me a prioritization approach indicating which of these failures are more important and where I should start applying fixes or resolving them.

KS
IAM Senior Software Engineer at MGM Resorts International
Centralized log onboarding has transformed root-cause analysis and streamlined alert-driven triage
I do not use automations within CrowdStrike Falcon Next-Gen SIEM at this point, but that is something that we want to do in the future. Maybe I did not experiment or did not investigate, but if we can get alerts based upon the CPU utilizations and the metrics over there, probably that would make this one tool used for everything. Actually, the circumstances that prompted my company to explore new SIEM solutions maybe include a point where the storage space or the license that we have, probably compared to other SIEM products, they have more, or the pricing and sales that go into the picture there. Again, that is above my pay grade to comment on, but it probably could be better if we can provide more storage of the data for the license that has been provided for organizations.
Kallamuddin Ansari - PeerSpot reviewer
Cyber Security Consultant at HR Software Solution
Centralized monitoring has improved threat response but cost control still needs refinement
Based on real operations used in our corporate IT environment, the key features include log correlation and incident view. Microsoft Sentinel's biggest strength is how it correlates multiple related alerts into a single incident. This significantly reduces alert noise and helps the SOC focus on real threats instead of isolated events. Another valuable feature is KQL-based threat hunting with Kusto Query Language. The flexibility of this language allows us to build custom hunting queries based on our environment's behavior. This is extremely useful for detecting low and slow threats or hidden threats that default rules may miss. Cloud-native scalability and stability is another important feature. Being cloud-native, Microsoft Sentinel scales well for medium to large corporate environments without infrastructure management. Stability has been solid in day-to-day production. SOAR automation using playbooks is a feature we highly recommend. Microsoft Sentinel's SOAR functionality helps automate repetitive SOC tasks like alert enrichment and notification. This saves analyst time and improves response consistency.
