An expensive solution to monitor internet traffic with multiple dashboards

The huge library especially the open source link, makes it the main engine for Corelight with some enhancements in the commercial version. It has a very powerful level, such as signature-based attacks or behavioral attacks, with enhancements in the design. It is very flexible for intelligent implementations like IPs, especially between big companies and banks. Corelight is easy to understand and monitor what is going on behind the team. The solution is already integrated with other systems like Suricata, Elastic, and Microsoft tools. It's very easy to integrate signature-based or behavior-based engines. You can use Elastic for the dashboards to get it from Corelight, along with all the benefits and expandability.

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.

"It does have capabilities of micro-segmenting a network, being able to create smaller segments of various types of applications separated by various tiers."

Cons

"Machine learning could be a good improvement, but it's very costly."

"In the next release, building a graphical user interface would be helpful."

"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."

"Corelight hasn’t added features in a long time."

"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."

"The setup of the solution could be simplified."

"It lacks full knowledge of physical side of the network topology."

"Traffic flow introspection topology visibility is definitely needed because at the moment, NSX-T lacks in this area."

"We would like tenant segmentation available in future releases."

"Just being more knowledgeable about the different functions."

"I would rate NSX's stability eight out of ten - there's room for improvement."

"The price could be better. The non-enterprise version of the product should also be improved. I would like VMware to expand beyond the network and provide some VLAN technologies and more. I think we have one, but it's more on the distribution side because it's more on the upper side of the network. I'm looking forward to that."

"It still needs to grow. There are still some features that it doesn't do, like it doesn't do multicasting."
