There sure is. Most big companies work that way I would imagine. I can install browser extensions, no problem but local apps are restricted. Also Dropbox and others are blocked at the corporate firewall level.
I mean, installing browser extensions to deliberately get around their security measures seems a little bit counterproductive. They aren't more secure than local apps. Do you take this company's security measures seriously or is it just some hurdle to get around for you?
Yes, which is why I posted the alternative to installing an app. You can use Keepass + drive/dropbox sync without installing anything using keeweb.
You do not need to install apps to access drive, dropbox, etc...
