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

2 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  2. 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

Gamma Communications operates primarily in the telecommunications sector targeting business customers in the Netherlands and Europe. Their business model focuses on B2B services including internet connectivity, unified communications, and cybersecurity solutions. The company maintains multiple regional websites indicating a broad European presence and partnerships. The use of advanced marketing and analytics tools suggests a mature digital marketing strategy. However, the absence of detailed privacy and security policies may impact trust with privacy-conscious clients. The company appears well-positioned with a consistent brand and clear service offerings.

Security posture

The website enforces HTTPS and uses several security and analytics scripts loaded asynchronously to minimize risk. No exposed sensitive data or vulnerable libraries were detected in the scanned content. However, the lack of explicit security headers (such as CSP, HSTS) and absence of published security policies or incident response contacts indicate areas for improvement. No vulnerability disclosure or security.txt files were found, which could enhance transparency and trust. Overall, the security posture is solid but could benefit from enhanced documentation and header configurations.

Recommendations

  1. Publish a comprehensive privacy policy detailing GDPR compliance and data handling practices.
  2. Add explicit security headers like Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  3. Provide a public security policy and incident response contact information to improve transparency.
  4. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Ensure all forms have proper security controls such as anti-CSRF tokens and input validation.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Google Tag Manager, Microsoft Clarity, and NitroPack for performance optimization. The site loads quickly and is mobile-optimized with good SEO practices including meta tags and structured data (JSON-LD). The use of multiple analytics and marketing tools indicates a mature digital infrastructure. There is no indication of outdated or vulnerable libraries. Hosting provider details are not explicit but the use of NitroPack and CDN services suggests a robust hosting environment. Accessibility is basic but functional. Overall, the technical implementation supports a professional and performant web presence.
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.
