Are my certificate files really safe?
Security, Privacy & Data Protection
Yes — your certificate files are securely stored and protected using enterprise-grade cloud encryption and access controls.
Where Your Files Are Stored
- All PDF uploads are stored in Azure Blob Storage, a Microsoft-managed cloud platform used by banks, governments, and healthcare systems
- 256-bit AES encryption-at-rest is enabled by default for every file — no exceptions
- All data in transit is protected via HTTPS using TLS 1.2+ encryption
Who Can See Your Files?
- Files are never public: Raw storage containers are private and cannot be browsed — not even by CertNudge staff
- Time-limited access: When you click “View PDF,” the system generates a one-time signed URL that expires after a short window
- Only your account: Can request and use this URL — no one else can access your file without it
- Zero persistent file links: Files are not exposed via permanent URLs or embedded into the page
Compliance & Reliability
CertNudge's storage infrastructure is hosted entirely within Microsoft Azure’s UK-based data centres, which are:
- ISO 27001, SOC 1/2/3, and GDPR compliant
- Regularly audited for security best practices
- Designed for durability and availability (≥ 99.9%)
Need to remove a file?
You can delete any uploaded certificate at any time from your dashboard — it is immediately removed from storage and no longer accessible via any link.
