An open-source solution that gave us insight into our clients' network traffic flow
We use the solution for packet capture sampling. We offer it as part of our managed service. It's so we can identify east-west traffic on a customer's network Corelight is low-cost and made on open-source, and the code is Zeek. It's an easy way for us to get visibility in a client's environment.…

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.

Pros

"It's an easy way for us to get visibility in a client's environment."
"It is easy to deploy and easy to handle."
"It's easy to create additional dashboards specific to supporting specific tasks."
"Corelight is easy to use."
"The most valuable feature is the embedded IDS from Suricata."
"RSA NetWitness does market analysis in a more granular form. It gives you full visibility."
"NetWitness Endpoint's most valuable features are its interoperability across many different operating systems and the ease of pivoting from network to endpoint via a single console."
"Ability to isolate the machine when there are malicious files."
"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."
"They have recently updated the features and the most valuable ones are the instant threat response, ease of use, web interface, integration, and easy access. RSA NetWitness Endpoint is very compatible with other solutions and technologies. However, they do not rely on third-party solutions and have most features built-in."
"We've contacted technical support several times. They've been very good. They have been able to help us resolve our issues."
"The most valuable feature is the way it captures the traffic, and it contains every detail of the communication."
 

Cons

"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."
"In the next release, building a graphical user interface would be helpful."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"Machine learning could be a good improvement, but it's very costly."
"Threat detection could be better."
"The solution lacks a reporting engine."
"The contamination feature could be improved."
"I would like to see Security Orchestration and Response Automation (SOAR) integration."
"The initial setup requires a high level of skill, then the setup is good and smooth."
"RSA NetWitness Network could improve on integration with non-native application integration."
"The threat intelligence could improve in RSA NetWitness Endpoint."
"We would like to see the hunting and investigation features of this solution improved, in order to provide better visibility of issues."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"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."
"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."
"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."
"It is an expensive product."
"NetWitness Endpoint is less costly than its competitors, but it offers fewer features."
"The cost depends on the number of endpoints that you want to monitor, but it is not expensive."
"We are on a three-year contract to use RSA NetWitness Network."
