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. 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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

NL College operates in the education sector focusing on language learning, leveraging accreditations from recognized institutions to build credibility. Their business model centers on providing tailored Spanish courses, exam preparation, and student support services including visa assistance and accommodation. The school targets international students, supported by multilingual content and diverse community testimonials. Marketing efforts include active social media engagement and use of tracking pixels for retargeting. The company appears small but professional, with a consistent brand and clear contact channels. No parent or subsidiary companies were identified, and no suspicious domains are linked.

Security posture

The website demonstrates a solid security foundation with HTTPS enforced and cookie consent implemented, aligning with GDPR requirements. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options suggests room for enhancement to mitigate risks like clickjacking and cross-site scripting. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of a publicly available security policy or incident response contact limits transparency in security governance. Overall, the security posture is good but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen defense against common web attacks.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and user trust.
  3. Conduct regular audits of third-party scripts and dependencies to identify and remediate potential vulnerabilities.
  4. Enhance accessibility features to improve inclusivity and compliance with standards.
  5. Maintain up-to-date privacy and cookie policies with clear user consent mechanisms aligned with evolving regulations.

Technical notes

Notes

The website is built using Vue.js, a modern JavaScript framework, and leverages multiple third-party services including Google Tag Manager, Facebook Pixel, TikTok Pixel, Mailchimp, and Cookiebot for marketing and analytics. Hosting utilizes AWS Cloudfront CDN for content delivery, contributing to moderate performance. The site is mobile optimized with responsive design and prefetching of CSS and JS chunks to improve load times. SEO is supported by proper meta tags and alternate language links. However, accessibility is basic and could be improved. No CMS was detected, suggesting a custom or static site architecture. Overall, the technical implementation is modern and functional with opportunities for security and accessibility enhancements.
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.
