The need for a proactive approach


Businesses have focused on perimeter defences and guarding known devices, but the traditional approach to cyber security isn’t enough to defend against today’s cyber threats. 


In our cloud-enabled mobile economy, there’s no longer a perimeter to defend. Work takes place in environments that organisations don’t control, on devices they don’t support, and on infrastructures they don’t manage. And as business have shifted more to the cloud, so have cyber attackers.
