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 is easy to deploy and easy to handle."
"The most valuable feature is the embedded IDS from Suricata."
"Corelight is easy to use."
"It's easy to create additional dashboards specific to supporting specific tasks."
"The feature that I have found the most useful is the decode of packets. It gives us a variety of information that helps us in figuring out what to look at. The networks are getting really complex, and without the information that we get from Iris Session Analyzer, we couldn't do our job. Its graphical user interface is also very easy to use and intuitive."
"A great feature is the memory utilization graph."
 

Cons

"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."
"In the next release, building a graphical user interface would be helpful."
"Machine learning could be a good improvement, but it's very costly."
"They can increase flexibility in the search engine. Basically, I go with the information I have at the time. If I could just type in the parameter that I want to search for and its value, it might be easier than having to do the groundwork upfront before I can get my traces."
"Sometimes the network analyzer will show that a server is down when it's actually working."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"I don't know what the cost to buy the solution was, but I doubt if it's a significant part of the budget as far as the maintenance and support are concerned."
