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.

Quotes from Members

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

Pros

"Nagios Core is stable."

"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."

"The solution is quite efficient."

"The reporting structure and the feature set are valuable to me."

"I would rate the overall solution ten points out of ten."

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."

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

"t was a little hard to get our setup represented in the configuration."

"The UI is a little outdated and graphics could be displayed in a better way."

"The solution could improve by having automatic mitigation. For example, as soon as a problem occurs the solution alarms and mitigates the situation immediately."
