No choice
Our customers want to exchange with our Sales force using Whatsapp, Instagram, Skype, Tinder... hmm no, not Tinder.
Of course neither the customers nor the sales force give a fuck about security or confidentiality, all of these being annoyances caused by these bloody IT guys who can't stop making work and life hard to their fellow coworkers... The only thing we could do was specifically saying (more precisely writing, knowing the value of words for salesmen and saleswomen) that we warned them, and we couldn't be held for responsible in case of data theft. I would be surprised if our situation was an exception.
