Hi! I'm one of the developers of the Sentry. Someone suggested I do a little intro bit here, so here goes.<p>The Sentry stemmed from over a decade of doing traffic analysis (from a security perspective) for local small and mid-sized businesses. We had a great conglomeration of tools (ntop, cacti, snort, some custom connection indexers, etc), but it was almost impossible to use effectively if you weren't the guy who made it.<p>We wanted our clients to be able to monitor their own network, so we set about making the Sentry. The primary feature of the Sentry is usability. Traffic analysis is typically hard. There's no reason it needs to be.<p>We would love to have any feedback you guys are willing to offer. Hackernews is famed for it's frank discussion. Bring it on.
