Traditional security, which focused on protecting an organisation’s perimeter, which meant placing trust in devices inside the network and having full control over all data flows, has grown less effective as the technology landscape has changed. In today’s modern world, we see a rise in remote work, portable devices, collaboration with third parties, cloud application (SaaS) usage, cloud infrastructure, and a technologically savvy workforce. This means data now flows across many external networks, cloud services, and endpoint devices, often in locations outside of traditional security’s corporate controls. To account for this increased attack surface, an organisation's security architecture design should move to a Zero Trust model.
