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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Google APIs, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

ByggeBolig AS operates in the Real Estate and Media sectors, providing content and community services related to housing and construction in Norway. Its business model relies on content publishing, community engagement, and advertising revenue. The platform partners with related Norwegian services such as Boligmappa.no and Hjemla.no, enhancing its ecosystem. The target audience includes homeowners and professionals interested in building and renovation. The company maintains a medium-sized online presence with consistent branding and a good reputation. Growth indicators include active content updates and user engagement through forums. The partnership ecosystem and use of multiple analytics and advertising tools suggest a mature digital marketing strategy.

Security posture

The website demonstrates a solid security posture with mandatory HTTPS, use of Google reCAPTCHA on user forms, and GDPR-compliant consent management. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of explicit security headers such as Content-Security-Policy and lack of a published security or incident response policy represent areas for improvement. The site uses multiple third-party scripts for analytics and advertising, which are managed with user consent. Incident response readiness and vulnerability disclosure mechanisms are not publicly documented, which could be a compliance gap. Overall, the security maturity is good but could be enhanced with formal policies and additional HTTP security headers.

Recommendations

  1. Implement and publish a dedicated security policy and incident response contact information on the website.
  2. Add explicit HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and Referrer-Policy to improve security posture.
  3. Create and host a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a custom CMS platform using jQuery and Bootstrap for frontend UI, hosted on Microsoft Azure. It integrates multiple analytics platforms (Google Analytics, Matomo, Hotjar, Plausible) and advertising networks (Google Adsense, Adnami, InMobi, DoubleClick). The site is mobile optimized with responsive design and good SEO practices. Performance is moderate, with asynchronous loading of scripts and deferred JavaScript to improve load times. The use of multiple third-party scripts introduces some complexity and potential risk, but consent management is implemented to comply with GDPR. Technical debt appears low, but the site could benefit from modern security header implementations and improved accessibility compliance.
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.
