It depends on the environment. If you put an SNMP base and it's an SNMP-based solution behind a stateful firewall, you will see an issue, but it isn't an issue with HelpSystems InterMapper as such. You need to have proper environment sources. If you put HelpSystems InterMapper behind a fast network and do basic inspections and filtering, I would say it is extremely reliable.

The stability is absolutely fantastic.

No, Intermapper seems rock solid. The application runs 24/7 in our NOC. I cannot remember an instance of it ever failing.

It's a stable solution.
