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.

Reliable and good support but can be expensive

I have no real complaints about the solution. Threat detection could be better. They need to enhance their threat intelligence feeds. We would like to have more IOCs or more trade intelligence to not only rely on the intelligence of the engineer in charge but to have some threat intelligence and some seeds of IOCs and to have the host have some artificial intelligence to reduce the number of false positives. I don't see this solution being very scalable. The solution is pricey.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It is easy to deploy and easy to handle."

"Corelight is easy to use."

"Corelight makes much easier the remediation of cyber attacks; instead of facing a chaotic amount of logs, Corelight provides correlated metrics that allow pivoting to find, in seconds, all the data related to an alert, detection, or asset."

"Corelight Open NDR has had a positive impact on my company, providing visibility as the Suricata engine can scan huge volumes of traffic, including north-south and east-west, revealing signatures and exposures I was not expecting and enabling me to catch them with Suricata alerts."

"Our company has seen massive improvements in cybersecurity position for our clients."

"Technical support seems to be good."

"It's an easy way for us to get visibility in a client's environment."

"It's easy to create additional dashboards specific to supporting specific tasks."

More Corelight Open NDR pros

"The stability of the RSA NetWitness Endpoint is very good."

"The most valuable feature of RSA NetWitness Network is the single unified dashboard from which you can manage all the different products of RSA. Additionally, the integration with native applications is good."

"It is very easy to use, and its usability is great. The use cases are also very easy. The visualizations of the use cases are magnificent. You cannot find this in any other solution. From my point of view, it is great."

"The interface of this solution is very flexible and easy to use."

"Technical support is knowledgeable."

"RSA NetWitness does market analysis in a more granular form. It gives you full visibility."

"The log correlation is good."

"It helps our security team respond more accurately when there are threats, then we get less false positives or negatives."

More NetWitness NDR pros

Cons

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

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

"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."

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

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

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

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

"This solution needs an upgrade in reporting. I have heard from RSA that they are working on this, but as of yet it is not available."

"The solution lacks a reporting engine."

"The solution doesn't have a reporting engine which would be helpful."

"The threat intelligence could improve in RSA NetWitness Endpoint."

"RSA NetWitness Network could improve on integration with non-native application integration."

"The solution is modular, for example you can buy the RSA ePack, which you buy as a module is not part of the conduit solution. They could include it and have it as an all-in-one solution."

"When analyzing something, you have to click several times. It requires a lot of effort to find something."

"One of the drawbacks of using this product is that when you deploy, you have to create MSI files."

More NetWitness NDR cons

Pricing and Cost Advice

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

"The cost depends on the number of endpoints that you want to monitor, but it is not expensive."

"They can easily adjust if you have the requirements which are required. If you have a budget cut or a budget constraint, they can bend."

"The pricing is not very economical. It is a quite costly product for India. One thing is that when you purchase it, you have to purchase a module separately."

"With RSA, there is flexibility in choosing the service, products, and the range that meets your requirement, as well as they are flexible in terms of pricing."

"I do not have any opinion on the pricing or licensing of the product."

"It is highly scalable. It can be bought based on your requirements."

"NetWitness Endpoint is less costly than its competitors, but it offers fewer features."

"The price of the solution depends on the environment. If the environment is large then it will cost more. However, the larger the environment with more endpoints, you will receive an increased discount. If the environment is very small, then you might think it is expensive. It is always better to buy in bulk to receive a discount. The minimum number of assets is usually 500, with discounts on 1000 and 2000."
