Cloud Security Misconfigurations UK Businesses Should Fix First
Summary: Many cloud breaches come from misconfiguration rather than advanced malware. Learn which weaknesses UK businesses should fix first.
Cloud platforms are powerful, but small configuration mistakes can expose large amounts of data. UK businesses often use Microsoft 365, Google Workspace, AWS, Azure, hosting dashboards, CRM platforms and file sharing tools without a single view of access and risk.
Public storage and oversharing
Check public buckets, shared folders, anonymous links, guest access and inherited permissions. Sensitive files should not be exposed through convenience sharing. Review who can download, edit, share and invite others.
Weak identity controls
Enable MFA, protect administrators, remove inactive users, block legacy authentication and review third-party app access. Identity compromise is one of the fastest routes to cloud data exposure.
Missing logs and alerts
Without logging, incidents become guesswork. Enable audit logs for sign-ins, file access, admin changes, email rules and external sharing. Alerts should be actionable and reviewed regularly.
Fix what attackers can reach
Prioritise public exposure, admin access, sensitive data repositories and systems connected to payments or customer records. A cloud security review should produce clear remediation actions, not only a list of settings.
