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 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"

  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

The business operates in the telecommunications sector with a business model centered on providing connectivity solutions to individuals and enterprises. Their market position is that of a significant local player, leveraging partnerships and a comprehensive service portfolio. The presence of partner domains such as tradein.one.nz and rewards.one.nz indicates an ecosystem approach to customer engagement and service enhancement. The company appears to have a mature digital presence with a focus on customer experience and service accessibility.

Security posture

The website employs HTTPS and uses modern web technologies including Google Tag Manager and Polymer custom elements. However, there are gaps in security best practices such as the absence of DNSSEC and missing security headers. The site uses multiple third-party tracking and marketing scripts, which may raise privacy concerns. No explicit privacy or cookie policies were found in the provided content, indicating potential compliance gaps. Overall, the security posture is moderate but could be improved by implementing DNSSEC, security headers, and clear privacy compliance mechanisms.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement comprehensive privacy and cookie policies with explicit user consent mechanisms to comply with GDPR and local privacy laws.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  4. Review and audit third-party scripts for privacy and security compliance to minimize data leakage risks.
  5. Establish and publish an incident response policy and contact channels to improve transparency and readiness.

Technical notes

Notes

The website is built using a modern tech stack including JavaScript frameworks, Polymer custom elements, and Brightspot CMS. It leverages CDN hosting and asynchronous loading of analytics scripts for performance. The site is mobile optimized with responsive design and good SEO metadata. However, the absence of DNSSEC and security headers indicates some technical debt in security hardening. Performance is moderate with room for optimization. Accessibility features are basic but present. Overall, the technical infrastructure supports a professional online presence but requires enhancements in security and privacy 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.
