traffic at the surface-level and asking binary
questions, this paradigm shift away from this
insufficient legacy approach asks the right
questions: Not simply ‘are you malicious?’,
but crucially: ‘do you belong?’
Informed by a nuanced understanding
of the recipient, their peers and the
organisation at large, every inbound,
outbound and internal email is analysed in
context, and is then re-analysed over and
over again in light of evolving evidence.
Asking the right questions and
understanding the human invariably
sets a far higher standard for acceptable
catch rates with unknown threats on first
encounter. This approach far outpaces
traditional email defences which have
proven to fail and leave companies and their
employees vulnerable to malicious emails
sitting in their inboxes.
Rather than desperately bashing away at
blacklisted domains and IP addresses in an
ill-fated attempt to beat the attackers, we
can change the game altogether, tilting the
scales in favour of the defenders – securing
our inboxes and our organisations at large. •
