0–100, higher is better. How it is calculated

NordLocker is a technology company specializing in secure cloud storage and file encryption services. It offers a zero-knowledge, end-to-end encrypted private cloud vault that allows users to securely store, back up, and share files across multiple devices and platforms. The company positions itself as a trusted provider of privacy-first cloud storage solutions, targeting both individual users and businesses. NordLocker is part of the larger Nord Security group, which includes related services such as NordVPN and NordPass. The website demonstrates a mature digital presence with modern technologies and a strong focus on user privacy and security. However, the current SSL/TLS configuration is invalid, which poses a significant security risk and undermines user trust. The site includes comprehensive privacy and terms of service policies, indicating good compliance with data protection regulations such as GDPR. Marketing and analytics tools are actively used, with moderate user tracking levels and consent mechanisms in place. Overall, NordLocker exhibits a strong security posture in terms of encryption and privacy architecture but requires urgent improvements in transport layer security to ensure safe user interactions.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

5 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

NordLocker operates in the competitive secure cloud storage market, leveraging its zero-knowledge encryption architecture as a key differentiator. Its business model is subscription-based, offering both free and premium plans with up to 2TB of private cloud storage. The company targets privacy-conscious consumers and businesses needing secure file storage and sharing. Its affiliation with Nord Security enhances its market credibility and expands its partnership ecosystem. The website's content and user reviews reflect a focus on simplicity, security, and cross-platform accessibility. The company maintains a consistent brand identity and provides multiple access points including web, desktop, and mobile apps. While no physical address or phone contact is provided, the presence of a support email and active social media channels supports customer engagement. The company appears large and well-established, with a strong emphasis on cybersecurity and privacy as core business values.

Security posture

NordLocker demonstrates a solid security foundation through its use of strong encryption algorithms such as AES-256, XChaCha20-Poly1305, and Ed25519, and a zero-knowledge architecture that ensures user data privacy. The presence of SPF and DMARC records with strict policies indicates good email security practices. However, the absence of a valid SSL certificate and lack of TLS protocol support on the main domain is a critical vulnerability that exposes users to potential man-in-the-middle attacks and data interception. The site also lacks HSTS, OCSP stapling, and session resumption mechanisms, which are important for robust HTTPS security. No explicit security policy or incident response information is found on the site, which may impact transparency and user confidence. Overall, while encryption and data protection are strong, transport layer security and incident response readiness require significant improvement.

Recommendations

  1. Immediately install and maintain a valid SSL/TLS certificate supporting TLS 1.2 or higher to secure all user connections.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce secure connections.
  3. Implement OCSP stapling and session resumption to improve SSL performance and security.
  4. Publish a clear security policy and incident response plan on the website to enhance transparency and trust.
  5. Regularly audit and update security headers and configurations to align with best practices and compliance requirements.
Technical notes

Notes

The website is built using modern web technologies including React and Gatsby, indicating a high level of technical maturity and performance optimization potential. Hosting is provided via Amazon AWS infrastructure, as inferred from IP addresses. The site uses multiple third-party analytics and marketing tools such as Google Analytics, Hotjar, Facebook Pixel, and Twitter Pixel, with appropriate consent mechanisms in place. However, the current page load time is relatively slow (6546 ms), which may impact user experience. Mobile optimization and accessibility are rated good, with responsive design and clear navigation. The absence of a valid SSL certificate is a major technical risk that must be addressed promptly. The site demonstrates good SEO practices with comprehensive metadata and structured data markup. Overall, the technical infrastructure is solid but requires improvements in security configuration and performance tuning.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
