Executive Key Takeaways
- Cyber Essentials requires high and critical vulnerabilities with CVSS >= 7.0 to be patched within 14 days of release.
- External vulnerability scans are a mandatory pass/fail component of Cyber Essentials Plus certification.
- Running HackGuardX year-round prevents last-minute assessment failures and retest fees.
1. Why Organisations Fail Cyber Essentials Plus on First Attempt
The most common cause of Cyber Essentials Plus failure is an unpatched external service, a forgotten subdomain running end-of-life software, or missing multi-factor authentication on a cloud service. Continuous scanning surfaces these issues weeks before your assessor runs their test.
