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.

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'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."

"Corelight is easy to use."

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

"The most valuable feature is the embedded IDS from Suricata."

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

"It's a scalable solution. We have around five to eight customers using RSA NetWitness Endpoint, and we hope to increase the number of users."

"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."

"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."

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

"The most valuable feature is the way it captures the traffic, and it contains every detail of the communication."

"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."

Cons

"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."

"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 threat intelligence could improve in RSA NetWitness Endpoint."

"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."

"I would like to see Security Orchestration and Response Automation (SOAR) integration."

"We would like to see the hunting and investigation features of this solution improved, in order to provide better visibility of issues."

"The solution lacks a reporting engine."

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

"Threat detection could be better."

"The contamination feature could be improved."

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."

"We are on a three-year contract to use RSA NetWitness Network."

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

"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 an expensive product."
