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

Tudu AS is a Norwegian IT company founded in 2016, specializing in digital solutions for business administration, including HMS compliance systems, secure collaboration platforms, and digital board portals. The company targets businesses seeking to simplify administrative and compliance tasks through user-friendly SaaS products. Their market position is supported by a professional website, customer logos, and active social media presence. Technically, the website is built on modern frameworks such as Nuxt.js and Vue.js, with integrations for analytics (Matomo, Google Tag Manager) and customer engagement (LiveChat). Security posture is strong with HTTPS, reCAPTCHA, and cookie consent mechanisms, though explicit security policies and headers could be improved. Overall, the site is trustworthy, well-designed, and compliant with basic privacy standards, though it lacks published privacy and terms of service documents.

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. 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';…

  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

  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

Tudu AS operates in the technology sector, providing essential digital tools for compliance and collaboration to Norwegian businesses. Their business model is B2B SaaS, focusing on HMS systems, secure communication, and board management. The company leverages partnerships (e.g., Brucy.io for hosting and site creation) and maintains a clear brand identity. Revenue likely derives from subscriptions or licenses for their software products. The target customer segment includes SMEs and organizations requiring streamlined administrative workflows. Growth indicators include a professional web presence and integration of modern digital marketing and analytics tools.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of reCAPTCHA on forms, and cookie consent via Cookiebot. No exposed sensitive data or vulnerable libraries were detected. However, the absence of explicit security policies, incident response contacts, and security.txt files indicates room for improvement in transparency and readiness. Security headers such as Content-Security-Policy and X-Frame-Options are not explicitly observed and should be implemented to enhance protection. Overall, the security posture is good but could be elevated to excellent with these additions.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement and publicly disclose a security policy and incident response plan with dedicated contact channels.
  3. Add explicit security headers (CSP, X-Frame-Options, X-Content-Type-Options) to harden the website against common attacks.
  4. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Continue enhancing transparency around data collection, retention, and user privacy to align with GDPR best practices.

Technical notes

Notes

The website is built using modern JavaScript frameworks Nuxt.js and Vue.js, ensuring a performant and responsive user experience. Hosting and CDN services are provided by Brucy.io, which supports fast content delivery. Analytics are handled via Matomo and Google Tag Manager, providing robust tracking capabilities. The site is mobile-optimized and accessible, with clear navigation and structured content. Technical debt appears minimal, but the site would benefit from explicit security header implementation and formalized privacy and security documentation to reduce operational risks.
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.
