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

NordVPN operates as a leading VPN service provider offering fast, secure, and privacy-focused internet access to a global audience. The company positions itself as a market leader with a comprehensive suite of cybersecurity products including VPN, threat protection, dedicated IPs, and dark web monitoring. The website reflects a mature digital presence with professional design, multi-language support, and clear navigation. Technically, the site leverages modern frameworks like Astro, uses Cloudflare DNS and CDN services, and implements strong security headers and HTTPS encryption. Privacy compliance is well addressed with cookie consent mechanisms and a comprehensive privacy policy. However, explicit contact information and incident response details are limited, which could be improved to enhance trust and compliance. Overall, the domain registration data aligns with the business claims, indicating a legitimate and trustworthy operation.

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

4 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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 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';…

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

NordVPN's business model is subscription-based, targeting individual users and businesses seeking online privacy and security. The company maintains a strong brand presence with multiple related services such as NordLayer and NordPass, indicating a diversified cybersecurity portfolio. The website's multi-language support and extensive product offerings suggest a large-scale operation with global reach. Partnerships and sister sites are well integrated, enhancing cross-selling opportunities. The absence of direct contact details on the main site may indicate a preference for centralized customer support through dedicated portals. The company demonstrates strong market positioning with recognized awards and guarantees, supporting customer confidence and retention.

Security posture

The website exhibits a robust security posture with enforced HTTPS, multiple security headers, and domain transfer protection. Cookie consent and privacy policies align with GDPR requirements, reflecting good compliance practices. No vulnerabilities or exposed sensitive data were detected in the analysis. However, the lack of a published security.txt file and explicit incident response contacts represents a gap in transparency and vulnerability management readiness. Enabling DNSSEC would further strengthen DNS security. Overall, the security maturity is high but could benefit from enhanced disclosure and incident response mechanisms.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and security.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Add explicit incident response contact information (e.g., security@ or abuse@ emails) on the website.
  4. Enhance visibility of contact information for security and compliance inquiries.
  5. Maintain and regularly update privacy and cookie policies to reflect evolving regulations.

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.
