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

xxllnc is a Dutch company specializing in developing smart applications for government and semi-government organizations, focusing on domains such as taxes, environment, social affairs, and case management. The company positions itself as a medium-sized, technology-driven provider with a clear focus on digital transformation in the public sector. Their website reflects a professional and consistent brand image with detailed product and team information, targeting government clients in the Netherlands. Technically, the website is built using modern frameworks such as Astro and Svelte, with a CMS likely based on Sanity. The site is well-optimized for performance and mobile devices, uses HTTPS with DNSSEC enabled, and integrates Google Tag Manager for analytics. Hosting appears to be managed via Vercel or a similar platform, ensuring fast load times and reliability. From a security perspective, the site demonstrates good practices including HTTPS enforcement and script integrity checks. However, it lacks some advanced security headers and does not publicly disclose privacy or cookie policies, nor incident response or security policies. No vulnerabilities or suspicious patterns were detected, and the domain registration data aligns well with the company's profile, supporting legitimacy. Overall, the website is trustworthy and professional but could improve privacy compliance and security transparency. Strategic recommendations include publishing privacy and cookie policies, enhancing security headers, and providing clear incident response contacts to strengthen user trust and regulatory compliance.

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

6 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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';…

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

xxllnc operates in the niche market of government software solutions in the Netherlands, offering a suite of applications tailored to various public sector needs such as tax processing, environmental planning, social services, and case management. Their business model is B2B, targeting municipalities and semi-governmental bodies. The company leverages partnerships and maintains dedicated subdomains for support, recruitment, and training, indicating a mature operational structure. The domain age and registration details support a credible market presence since 2020. The company’s competitive advantage lies in its specialized applications and integration capabilities within the government ecosystem.

Security posture

The website exhibits a moderate to good security posture with HTTPS and DNSSEC enabled, script integrity attributes, and minimal security headers like X-Content-Type-Options and Referrer-Policy. However, it lacks comprehensive security headers such as Content-Security-Policy and Strict-Transport-Security, which are recommended for enhanced protection. No exposed sensitive data or vulnerable libraries were detected. The absence of a published security policy or incident response contact limits transparency and readiness perception. Compliance with GDPR is not explicitly demonstrated on the site, and cookie consent mechanisms are missing, representing compliance gaps.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement a cookie consent mechanism to inform and obtain user consent for tracking.
  3. Add advanced security headers including Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Provide a publicly accessible security policy and incident response contact information.
  5. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.

Technical notes

Notes

The website is built on a modern and performant tech stack including Astro and Svelte frameworks, with content managed likely via Sanity CMS. It uses Google Tag Manager for analytics and Partytown for script offloading, indicating attention to performance optimization. Hosting appears to be on a scalable platform such as Vercel. The site is mobile-optimized and accessible with good SEO practices. Technical debt appears low, but opportunities exist to enhance security headers and privacy compliance. Overall, the infrastructure supports a reliable and user-friendly digital 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.
