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

7 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

N.nu holds a strong market position in Sweden as a leading website builder since 2009. Its competitive advantages include ease of use, full HTML/CSS control, and a comprehensive feature set at a competitive price point. The company targets a broad audience from novices to experts, with a focus on small to medium-sized businesses and individual users. Revenue is primarily generated through annual subscriptions. The partnership with Codalex AB provides corporate backing and credibility. The ecosystem includes several partner sites and showcases customer testimonials to build trust. Growth indicators include a large active user base and continuous platform improvements.

Security posture

The website enforces HTTPS and uses secure form inputs, which are positive security practices. However, it lacks DNSSEC, and no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, representing areas for improvement. There is no visible incident response or security policy published, and no vulnerability disclosure or security.txt file is present. Tracking scripts are used without a cookie consent mechanism, which may pose GDPR compliance risks. Overall, the security posture is moderate but could be enhanced by implementing recommended headers, DNSSEC, and privacy compliance mechanisms.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web attacks.
  3. Add a cookie consent banner and detailed cookie policy to comply with GDPR and other privacy regulations.
  4. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and enhance user trust.

Technical notes

Notes

The website uses a modern and stable technology stack including Bootstrap 3.3.4, jQuery, and Font Awesome for UI components and icons. It integrates Google Analytics and Redistats for visitor tracking. Hosting is supported by Cloudflare DNS, providing reliable DNS resolution. The site is mobile optimized and loads quickly, with a clean and professional design. However, the absence of DNSSEC and security headers indicates some technical debt in security hardening. The use of proprietary CMS/platform suggests control over content but also requires ongoing maintenance to keep up with security best practices. Overall, the technical infrastructure is solid but could benefit from security enhancements and privacy compliance improvements.
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.
