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

Patch22 is a niche real estate development project focused on sustainable, flexible wooden high-rise construction in Amsterdam North. The project is led by architect Tom Frantzen and building manager Claus Oussoren under Lemniskade Projects. The website presents professional content highlighting architectural innovation and sustainability, targeting architects, developers, and potential residents. The technical infrastructure is based on WordPress with modern plugins and frameworks, providing a good user experience and mobile optimization. Security posture is adequate with HTTPS enabled but lacks security headers and formal security policies. Privacy compliance is limited due to absence of cookie consent and detailed privacy mechanisms. Overall, the website is trustworthy and professionally maintained but could improve in 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

9 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

Patch22 occupies a specialized market segment in sustainable real estate development with award-winning architecture. Its business model centers on innovative wooden construction and flexible housing solutions. The company leverages partnerships with architectural and design firms and maintains an active social media presence. Revenue streams likely derive from property sales or leases. The website content and domain age align with the business history, indicating stable operations. Growth potential exists in sustainable construction markets, though the small size and niche focus limit scale. Strategic partnerships and certifications enhance credibility.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data exposure. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, which may hinder rapid response to security events. Privacy compliance gaps exist due to missing cookie consent mechanisms. The site should implement security best practices and formal policies to improve resilience and regulatory compliance.

Recommendations

  1. Implement comprehensive security headers to enhance protection against common web attacks.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR and other privacy regulations.
  3. Publish a security policy and incident response contact information to improve transparency and readiness.
  4. Enable DNSSEC for the domain to strengthen DNS security.
  5. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities.

Technical notes

Notes

The website uses WordPress CMS with WPBakery Page Builder, Slider Revolution, Bootstrap, and JavaScript libraries like jQuery and GSAP. The design is responsive and mobile-optimized with good SEO meta tags and structured data (JSON-LD). Performance is moderate, with some heavy slider assets potentially impacting load times. Accessibility features are basic but present. Hosting provider details are not disclosed. The site lacks advanced analytics or tracking scripts, indicating minimal user tracking. Technical debt appears low but could be improved by optimizing assets and enhancing security configurations.
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.
