Room For Improvement

Cisco Secure Network Analytics needs better integration, user interface, AI features, and simplified setup with improved training and database management.
VMware NSX struggles with high costs, complex configurations, integration issues, and requires improvements in scalability, user-friendliness, and pricing.
The solution should have the ability to analyze security events not only at the network layer but also at the application and OS layers.
Group Head at Stpi
Proper management of the database is also important; it should be centralized for easier data collection from a single database.
CEO at BRIGHT-i SYSTEMS LIMITED
Advanced reporting and scheduled compliance reports look very attractive for audit and compliance teams at implementation time and can generate structured reports for visibility, risk posture, and traffic summaries.

Featured Reviews

Akash Das Barman - PeerSpot reviewer
Cyber Security Trainee at DataSpace Academy
Network analytics has reduced investigation time and provides deeper visibility into lateral movement
Several features often look very promising during evaluation or implementation but end up being used only lightly in day-to-day operations. Advanced reporting and scheduled compliance reports look very attractive for audit and compliance teams at implementation time and can generate structured reports for visibility, risk posture, and traffic summaries. In practice, many teams do not rely on it heavily because SIEM tools or GRC platforms already handle reporting better. Built-in threat intelligence feeds represent another area where expectations do not always match usage. The platform includes threat intelligence-based detection and classifications. Initially, teams expect to depend on this heavily, but later SOC teams often prefer their own threat intelligence feeds or correlate intelligence inside SIEM instead. The built-in feeds are used but not as a primary detection source. Automated incident summaries and guided investigation views are designed to simplify triage by automatically grouping related activity into incidents. However, teams often move away from them due to various factors affecting adoption.
TAIYAB HASAN - PeerSpot reviewer

Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.
