I work for a managed IT provider that offers cloud services. We have hundreds of VM servers running that would greatly benefit from the ability to monitor bandwidth usage at the level of detail that GlassWire offers. However, I have to second Mr. Bond's sentiment that without access to the data, it's a deal-breaker. Without the ability to export that data into a universally compatible format, we can't use that data to develop better usage and security policies, we can't combine that data with all the other data we gather to develop better, more profitable solutions, we can't use that data to show our clients how and why their current IT strategy sucks and why they need us to fix it all (for a modest fee).
More importantly... without the ability to export the collected data, I can't make a case to my company to consider purchasing your software. Seriously, in the age of "big data," it's absurd that this cannot be done. There are TONS of firewall applications out there. There aren't a lot of programs out there that collect application-layer bandwidth usage data as easily and efficiently as yours does. You're missing out on a huge opportunity by leaving out such a base feature. Even if you only export comma-delimited text at first, at least it's something. More difficult formats like Excel can come in time.
Thank you for an awesome program. I will be on the lookout for this feature in the future.
