Cloud security vs cybersecurity: what UK financial firms need to know
Moving data, applications and workloads to the cloud brings flexibility, but for financial services firms it also brings a specific set of regulatory and operational responsibilities.
Cloud security and cybersecurity are closely connected, but they are not the same thing. For firms regulated by the FCA and PRA, knowing the difference is not just a technical detail. It shapes how you demonstrate operational resilience, meet third-party risk requirements, and respond when something goes wrong.
Alternit One helps financial services businesses design and manage secure cloud infrastructure, covering identity governance, network security, monitoring and resilience. Here's how cloud security and cybersecurity differ, and why financial firms need both working together.
The security landscape is changing
Cloud adoption has changed how financial firms store data and run critical systems. Public, private and hybrid environments mean more areas to secure, and more areas regulators expect firms to account for.
According to IBM's 2026 Cost of a Data Breach Report, the global average cost of a data breach reached US$4.99 million, up 12% from the previous year. AI-driven attacks increased by 56%. For firms in scope of FCA operational resilience rules, a breach isn't just a cost. It can trigger reporting obligations and scrutiny of your third-party arrangements.
What is cybersecurity?
Cybersecurity is the broader practice of protecting an organisation's systems, networks, devices, applications and information from digital threats. It looks at the organisation as a whole, not one technology or environment.
It covers:
Area | What it means |
Threat detection and monitoring | Spotting suspicious activity across the estate |
Endpoint protection | Securing laptops, devices and access points |
Identity and access management | Controlling who can reach what |
Vulnerability management | Finding and fixing weaknesses before attackers do |
Incident response | Acting fast when something goes wrong |
Business continuity | Keeping the firm running through disruption |
What is cloud security?
Cloud security is more specific. It protects cloud-based infrastructure, applications, workloads and data, and it addresses risks created by how a firm configures and uses cloud platforms.
For a financial services firm, this typically includes:
Cloud identity and privileged access controls
Network segmentation between systems handling client data
Encryption of sensitive financial data, at rest and in transit
Secure cloud configuration and continuous monitoring
Backup and disaster recovery aligned to resilience requirements
Cloud compliance evidence for audits and regulatory reviews
Cloud security vs cybersecurity, side by side
Cloud security | Cybersecurity | |
Scope | Cloud environments specifically | The organisation's entire digital environment |
Protects | Cloud workloads and services | Systems, devices, networks, data, applications |
Focus | Cloud configuration and access | Risk across every environment |
Role | One part of the strategy | The overall framework |
In simple terms: cloud security sits inside cybersecurity. A firm can have strong cloud controls and still carry risk elsewhere, for example through poorly secured employee devices or excessive access
privileges that have nothing to do with the cloud itself.
Why UK financial firms need both cloud security and cybersecurity
Cloud environments connect to users, devices, applications and third parties. A weakness anywhere in that chain becomes a cloud security risk.
Compromised employee credentials are a common way in. IBM X-Force research shows attackers increasingly target identity and application layers rather than infrastructure directly. For a regulated firm, that means access reviews, authentication controls and third-party oversight all need to work together, not sit in separate silos.
Building a connected strategy: what we'd prioritise
Identity and access. Review privileged accounts and authentication controls regularly. Removing unnecessary access limits the blast radius if credentials are compromised.
Network and data protection. Segment cloud networks, encrypt sensitive data throughout its lifecycle, and know exactly where client data lives.
Resilience and governance. Build backup, disaster recovery and continuity plans that specifically account for cloud and SaaS incidents, with monitoring that keeps pace as your environment changes.
Which approach does your firm need?
Both. Cloud security should sit inside a broader cybersecurity strategy, not operate as a separate workstream.
Cybersecurity = the wider security framework
Cloud security = protection focused specifically on cloud environments
Cloud cybersecurity = applying cybersecurity principles to cloud-based systems, workloads and data
For a regulated firm, this means identity governance, incident response and resilience planning should all extend into the cloud rather than treating it as a separate concern.
