System Administrator at W. O. Grubb Steel Erection, Inc.
We currently rely on disaster recovery and backup recovery, which takes time to recover, during which you're basically blind, so I'm pushing my leadership team to switch over to a clustering environment for constant availability.

Room For Improvement

CrowdStrike Falcon SIEM needs better dashboards, automation, storage, licensing flexibility, and more cat-themed threat actor integrations.
Users seek improved training, data management, UI, pricing, threat detection, performance, and feature expansion in Splunk Enterprise Security.
I would suggest including data normalization, specifically a way to easily normalize data from different sources, as currently you can do it, but it is a little bit more labor-intensive.
System Administrator at W. O. Grubb Steel Erection, Inc.
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.
IAM Senior Software Engineer at MGM Resorts International
I believe CrowdStrike Falcon Next-Gen SIEM can be improved by continuing on the path it is on.
Security Operations at a financial services firm with 5,001-10,000 employees
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
Resident Consultant (Security Analyst) at helpag
Splunk Enterprise Security is not something that automatically picks things; you have to set up use cases, update data models, and link the right use cases to the right data models for those detections to happen.
Security & Risk Analyst at a computer software company with 1,001-5,000 employees
For any future enhancements or features, such as MLTK and SOAR platform integration, we need more visibility, training, and certification for the skilled professionals who are working.

The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.

I find it to be affordable, which is why every industry uses it.

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.
Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.
