Cyber Security Architects at VaporVM
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.
Security Consultant at Matiq
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.

Featured Reviews

HarshBhardiya - PeerSpot reviewer
SOC Engineer at a outsourcing company with 10,001+ employees
Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.
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.
KamranBhatti - PeerSpot reviewer
Network Engineer at a computer software company with 11-50 employees
Helps reduce response time but has room to improve customization complexity
We are not working on simple standalone solutions like Kaspersky DDoS Protection or Hybrid Cloud Security. Once you understand Zabbix, then it is easy to customize those web pages and graphs for our customer use. It is fully automated to your requirements. Zabbix is working fine with no issues, and I am satisfied with it. We have combined Zabbix and SolarWinds. The integration works fine, and it is easy to integrate Zabbix with the IT environment. We were trying to purchase MDR (Managed Detection and Response), but we are not working on that. I don't have real experience with MDR. We are using Falcon software for that. We are working with Falcon Complete, not with Sandbox. We are not using Kaspersky for business or cloud protection. For that, we are using Zabbix CrowdStrike Falcon Complete solution. I have given this review an overall rating of 8.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
