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. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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 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

The company targets real estate investors and partners interested in sustainable and socially responsible investments. Their business model integrates operational expertise with ESG leadership, differentiating them in a competitive market. The portfolio spans multiple major U.S. cities, indicating geographic diversification and growth potential. Certifications such as PRI, GRESB, and B Corporation status reinforce their commitment to responsible investment practices. The firm maintains active social media channels and provides detailed reporting, enhancing transparency and stakeholder engagement. No suspicious or unrelated domains were found, indicating a focused and legitimate business ecosystem.

Security posture

The website employs HTTPS with a valid SSL certificate and domain status protections that prevent unauthorized transfers or deletions. However, DNSSEC is not enabled, which could expose DNS queries to spoofing attacks. No explicit security policies or incident response information are published, which could be improved to enhance trust and preparedness. No vulnerable libraries or exposed sensitive data were detected. The absence of security headers is a minor gap that can be addressed to improve defense-in-depth. Overall, the security posture is good but could benefit from additional hardening and transparency.

Recommendations

  1. Enable DNSSEC to secure DNS queries and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy and X-Frame-Options.
  3. Publish a clear security policy and incident response plan on the website.
  4. Add a cookie consent mechanism to comply fully with GDPR and privacy best practices.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on WordPress with modern front-end technologies including lazy loading images and slick sliders for enhanced user experience. SEO is well implemented using Yoast SEO plugin with comprehensive metadata and structured data (JSON-LD). The site is mobile optimized and performs well with fast loading times. Hosting and DNS are managed via reputable providers (GoDaddy and Cloudflare). There is no evidence of technical debt or outdated components. Opportunities exist to improve security headers and DNSSEC for better resilience. Overall, the technical infrastructure supports a professional and scalable 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.
