Key Cyber Essentials 2026 Changes:
Mandatory Multi-Factor Authentication (MFA) – If a cloud service supports MFA, it must be enabled. This applies to cloud platforms, administrative accounts, and remote access. Not enabling MFA where available can result in an automatic assessment failure.

Expanded Scope for Cloud Services and Devices
Any device or cloud service storing or processing company data is in scope unless it is demonstrably segregated. The update removes ambiguity around SaaS platforms and remote working.

14-Day Vulnerability Remediation Rule
High-risk or critical security updates must be applied within 14 days, including vendor-issued fixes. This strengthens patch management and reduces exposure to known threats.

Stronger Backup and Recovery Expectations
Organisations must demonstrate that data can be reliably restored after a cyber incident. Backups should support practical recovery, not just exist on paper.

Why immutable backups matter
While not mandatory, immutable backups can be your last line of defence. Ransomware attackers often target backup systems first. Using a write-once, read-many (WORM) approach ensures recovery points cannot be altered or deleted.

Cyber Essentials provides a strong security baseline, but building resilience beyond compliance ensures your organisation can recover quickly when incidents occur. Call us on 0161 464 6101 or email hello@datacentreplus.co.uk to see how we can assist you too.
