I'd say the point is valid though if the only function the tunnel is supposed to fulfil is channelling traffic from and to a web browser.

As far as browsers go, only Internet Explorer lacks SOCKS5 support. And I doubt an office which such stringent header filtering has an IT department that doesn't provide people with proper browsers...

I'd actually argue that an office with stringent and archaic filtering of internet use is precisely the type of office to provide only IE, laden with corporate spyware.
