High performance, quick packet monitoring, and helpful support

The solution could improve by having automatic mitigation. For example, as soon as a problem occurs the solution alarms and mitigates the situation immediately. In a feature release of the solution they should add features related to automation and remediation. Automation would help increase level of security the solution provides.

"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."

More Nagios Core pros

"The unique selling point of NIKSUN is its ability to scale and its reporting capabilities. NIKSUN captures the packets at a very high speed, from one GB to 160 Gbps also. It offers report granularity in nanoseconds."

"The most valuable features of NIKSUN NetVCR are its performance and forensic capabilities. Additionally, the information that the solution provides is highly detailed and useful. When dealing with network traffic packets can be sent at a high speed causing some security issues, but this solution is able to rapidly monitor the packets providing security."

Cons

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."

"The user interface could be more interactive because it is pretty basic."

"It is a bit slow due to latency."

More Nagios Core cons

Pricing and Cost Advice

"It's free."

"Nagios Core is free to use."

"I would rate the solution's pricing an eight out of ten."

"The product is cheaply priced."
