Managing threats to organisations can no longer be separated between departments or siloed out to service providers. With data in the Cloud and people on the ground in new geographies, the need to evolve the relationship between logical and physical controls has increased. The key to holistic security is to bring all aspects of security under one umbrella to ensure all bases are covered.
