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

3 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Nimsys operates in the telecommunications sector, providing ICT infrastructure and communication services primarily to businesses in the Netherlands. Their business model is B2B, offering a portfolio of solutions including cloud telephony, Microsoft Teams integration, mobile and internet services, and workspace management. The company benefits from its association with Gamma Group, enhancing credibility and market reach. Their client base includes large enterprises, indicating a capacity to serve demanding customers. The website reflects a focus on quality service, fast deployment, and personal support. Strategic partnerships and certifications like ISO 27001 further position Nimsys as a reliable ICT partner in a competitive market.

Security posture

The website demonstrates a solid security posture with HTTPS enforced, DNSSEC enabled, and ISO 27001 certification prominently displayed. Privacy compliance is evident through a comprehensive privacy policy, cookie consent mechanisms, and GDPR adherence. However, the absence of explicit incident response contact information and a security.txt file suggests room for improvement in vulnerability disclosure and incident management transparency. No vulnerabilities or exposed sensitive data were detected in the analysis. The use of third-party scripts is controlled, but continuous monitoring is recommended to mitigate risks from external dependencies. Overall, the security maturity is good, supporting business trust and regulatory compliance.

Recommendations

  1. Publish explicit incident response and abuse contact information on the website.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosure.
  3. Enhance website accessibility features to meet higher compliance standards.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  5. Maintain and communicate data retention policies to strengthen privacy compliance.

Technical notes

Notes

The website is built on WordPress CMS, leveraging jQuery and optimized with NitroPack for performance. It uses Google Tag Manager and Microsoft Clarity for analytics and tracking, alongside Cookiebot for cookie consent management. The site is mobile-optimized with responsive design and good SEO practices including meta tags and structured data (JSON-LD). Hosting details are limited but domain registration is stable and DNSSEC enabled, indicating a secure DNS setup. Performance is fast with lazy loading and prefetching techniques. Technical risks are minimal, though continuous updates and security audits are advisable to maintain robustness.
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.
