Corelight excels in data visibility, deploying open-source technology to facilitate cost-effective security monitoring and incident response. Its integration capabilities enhance threat detection and forensics, making it a vital tool in cybersecurity.

Room for Improvement: VMware NSX should focus on improving scalability and enhancing cloud service integration, alongside creating smoother migration paths from legacy systems. Its user interface could be made more intuitive to improve user experience. Corelight needs to address its high pricing and simplify its architecture to increase accessibility and adoption rates, although its interface could benefit from an overhaul for better usability.

Ease of Deployment and Customer Service: VMware NSX offers flexibility in deployment across various cloud environments, yet its complex setup often requires skilled engineering support, which can be a hurdle. Corelight's deployment is straightforward, allowing for quicker implementation. Both products have gaps in customer service, with NSX facing slower support response times and Corelight struggling with market penetration.

Pricing and ROI: VMware NSX tends to be more expensive, often bundling features that are not always necessary, which raises costs.

Network visibility has transformed how we detect nation state threats and protect critical industry

Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale. However, I think with a lot of the artificial intelligence that they are building in, it is getting a lot easier to query in the platform. I would definitely encourage them to continue down that path where anybody can hop into the platform and start running queries, whether it is a simple instruction like I want this, and an artificial intelligence process can actually build the query and do it. I think that would be super powerful. Cyber skill sets are in high demand, and there is a huge backlog in cyber talent. We cannot fill all the positions we need. The easier we can make these cyber systems for people to pick up and be effective on, I think is really key. Explainability of data is hyper important. In the past few artificial intelligence related updates we have gotten from Corelight, that has been one of the first questions our team has asked every time or that I have asked: show me what the model is doing, show me how it came to this analysis. Within Investigator platform, they are able to walk through and see exactly what data the artificial intelligence pulled from where and why it did what it did as far as making its suggestions. They have definitely built their system with artificial intelligence in mind up front, and having that openness as one of the key features of any of their artificial intelligence and machine learning processes in the platform is important. The issue with black boxes is obviously hallucinations from artificial intelligence and just not being able to trace to ground truth. When we are talking about these cyber incidents and being able to do forensics, you need to be able to pinpoint and tie everything together, and black boxes really obscure that and prevent you from doing so. Corelight has done a really good job of making sure that everything is explainable and everything is mapped when it comes to leveraging any of their artificial intelligence features.

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.

Cons

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

"Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale."

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

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

"It's an expensive solution and the price could be reduced."

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

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

"The response time of the technical support team could improve. We also sometimes had the feeling that they didn't properly understand the issue."

"The solution could benefit from improvements in its pricing and scalability."

"If an organization is not able to use NSX to its full potential (Switching, Routing, Load-balancing, Firewall, IDS, IPS etc.) then its not worth it."

"VMware NSX can improve the migration tools from the older environments to the new environment. For example, the NSX-V has become a legacy solution, it's out of support, but customers are able to keep using it. For migration purposes, it's better for them to provide a proper tool. It will be easy to migrate from an old environment to a new one."

"It might be nice to have more AI in the future."

"We have been satisfied with the technical support. They were able to solve our problems. However, they could be faster."

"The ticket support response time from VMware could be improved. Often, callbacks are delayed, which can be problematic if the servers are in production."

"Just being more knowledgeable about the different functions."

More VMware NSX cons

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."

"There is a license required for this solution and there is also a support license available. The price of the solution could be better."

"The price is significantly high and it can be a hurdle for many potential users."

"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."

"VMware has a subscription and perpetual license. In the New Year, they're changing many things about the licensing model. Previously, NSX was licensed according to the number of sockets inside the appliance, so we bought VMware licenses based on that. However, that may have changed this year. We are still contacting the vendors to understand the new licensing strategy."

"We are using the free version of the solution."

"The price could be better. We pay for the license every three years. The last time I checked, it cost around three million pesos in the Philipines. Most of the expense will go towards implementation and renovation."

"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."

"The price of VMware NSX is reasonable."
