The UK government's announcement that top US cloud groups – including Microsoft, Google, Amazon, and Oracle – will be scrutinised as 'critical third parties' is a stark reminder of the country's reliance on foreign cloud services. According to the Treasury, this move aims to bolster digital resilience, with a focus on mitigating risks to national security and data protection. The number of UK businesses leveraging US-based cloud providers has grown exponentially in recent years, with an estimated 90% of UK companies using at least one US-based cloud service.
The designation will enable regulators to conduct more thorough assessments of the top US cloud groups' impact on the UK's cyber security and resilience. This enhanced scrutiny is expected to lead to improved risk management strategies and better data protection measures for consumers. For example, a study by the Centre for Data Protection found that 71% of UK SMEs would be severely impacted in the event of a major cyber breach involving a US-based cloud provider.
While some experts have raised concerns over the potential for regulatory overreach, many in the tech industry welcome this move as a step towards greater transparency and accountability among cloud providers. The Financial Conduct Authority has already implemented stricter data protection regulations, which are set to come into effect later this year. As part of this effort, cloud providers will be required to disclose more information about their security protocols and risk management practices.
