Security score

79/100

Risk levelLow

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

Gamma Communications is a large telecommunications company based in the Netherlands, offering a broad portfolio of business communication solutions including internet, mobile telephony, Microsoft Teams integration, cybersecurity, and managed networks. The company operates internationally with multiple country-specific domains, indicating a strong market presence in Europe. The website is professionally designed with good navigation and mobile optimization, reflecting a mature digital infrastructure. The technical stack is modern, leveraging WordPress CMS with NitroPack optimization and multiple analytics and marketing tools. Security posture is solid with HTTPS enforced and no visible vulnerabilities, though explicit security policies and incident response information are absent. Privacy compliance is lacking due to missing privacy and cookie policies. Overall, the website is trustworthy and business-focused but would benefit from enhanced privacy and security transparency.

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 positions itself as a key player in the telecommunications sector, targeting business customers with tailored communication solutions. Its competitive advantage lies in its comprehensive product suite and international footprint. The business model is B2B, focusing on providing scalable and integrated communication services. The presence of multiple related domains suggests a well-established partnership and subsidiary ecosystem. The company leverages digital marketing and analytics tools to engage customers, though privacy compliance gaps may pose regulatory risks. Growth indicators include diversified offerings and multi-country operations.

Security posture

The website demonstrates a good security baseline with HTTPS and no exposed sensitive data. However, the absence of security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in security governance and transparency. The use of multiple third-party scripts requires ongoing monitoring to mitigate supply chain risks. No critical vulnerabilities or malware indicators were detected. Enhancing security headers and publishing formal security documentation would strengthen the security posture and build customer trust.

Recommendations

  1. Publish a comprehensive privacy policy and cookie consent mechanism to ensure GDPR compliance.
  2. Implement and publicly disclose a security policy and incident response procedures.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options.
  5. Regularly audit and update third-party scripts to minimize security risks.

Technical notes

Notes

The website is built on WordPress with NitroPack for performance optimization, ensuring fast load times and good mobile responsiveness. It uses jQuery and Bootstrap for UI components and integrates multiple analytics and marketing tools including Google Tag Manager, Microsoft Clarity, LinkedIn Insight, Qualified, and Sleeknote. The site employs structured data (JSON-LD) for SEO and branding consistency. Hosting provider details are not explicit, but CDN usage is evident. Accessibility features are basic, and SEO optimization is good with proper meta tags and Open Graph data. Technical risks include reliance on multiple third-party scripts and lack of advanced security headers.
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.
