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

8 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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

The organization targets local governments, journalists, candidates, and residents, offering services in urban planning and public construction. Its business model is that of a public agency focused on sustainable urban development. The website content and social media presence support its market position as a reputable public sector entity. The lack of direct contact emails or phone numbers on the homepage suggests a structured approach to communication, likely centralized on dedicated contact pages. The agency appears to maintain a medium-sized workforce and actively recruits new talent, indicating growth and operational scale.

Security posture

The website enforces HTTPS and includes a cookie consent banner, demonstrating compliance with privacy regulations. However, no explicit security policies or incident response contacts are published, which could be a gap in transparency. The absence of security headers like Content-Security-Policy or X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The use of Google Analytics and Tag Manager indicates moderate user tracking, balanced with privacy compliance. Overall, the security posture is good but could benefit from enhanced transparency and header configurations.

Recommendations

  1. Implement and publish a dedicated security policy and incident response information to enhance transparency.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  3. Provide clear contact information for security incidents or abuse reports.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Maintain and regularly review privacy compliance measures, especially regarding analytics and cookie management.

Technical notes

Notes

The website is built on a modern React and Next.js stack, ensuring good performance and mobile responsiveness. It uses Google Analytics and Tag Manager for analytics and tracking. The site is well-structured with proper meta tags for SEO and social sharing (Open Graph and Twitter cards). Images are optimized with responsive loading and modern formats (AVIF, WebP). No CMS was explicitly detected, suggesting a custom or headless approach. Hosting provider details are not evident from the HTML. Overall, the technical implementation is robust, with opportunities to enhance security headers and incident response capabilities.
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.
