Cloud and SaaS platforms have transformed the way organisations work. Services that once sat behind a clearly defined network boundary are now delivered through collaboration tools, identity platforms, remote access services and line-of-business applications. They are fast to adopt, easy to scale and often essential to day-to-day operations. But they also create a simple security truth: you cannot protect what you cannot see.
For many organisations, the question is no longer whether cloud services are being used, it is whether the organisation has a reliable, up-to-date view of where those services are, who owns them, who has access and how they are being managed. Without that visibility, controls become inconsistent, governance weakens and risks become impossible to manage.
This matters even more as NCSC’s Cyber Essentials scheme continues to reflect the realities of modern cloud-first environments. The scheme’s latest requirements place greater emphasis on cloud services, access control and multi-factor authentication. Any cloud service used to store or process organisational data needs to be understood, assessed and controlled, including SaaS platforms that may have been adopted by individual teams outside central IT oversight.
When this visibility is missing, environments quickly fragment. New tools appear, teams adopt different platforms and access decisions become harder to track. Individually, these services may appear low risk. Collectively, they can create blind spots that make it difficult to demonstrate control, maintain compliance and respond confidently to emerging threats.
A clear cloud inventory is key to overcoming this challenge. At a minimum, it should identify what services are in use, what data they process, who is responsible for them, who can access them and whether essential controls such as multi-factor authentication are enabled. This is not just an administrative exercise; it is the starting point for applying security consistently across a distributed digital environment.
