Instant messaging is increasingly penetrating the workplace, and
law firms are no exception. A recent study estimates that nearly
70% of employees use smartphones for business, and that, of those,
73% use instant messaging apps installed on their phones for that
purpose.
Whilst it may be unsurprising that instant messaging has become
the top communication tool for employees using their smartphones
for business, significantly outstripping the use of smartphones for
emails (66%) and voice calls (58%),1 what is probably
less well known is that, whilst one of the leading messaging app
provides end-to-end encryption, ensuring that only the sender and
receiver can read the message and not third parties, with some
other popular messaging apps, it is either only optional, or not
available at all.
