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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Coldwell Banker operates as a major real estate brokerage and franchise network, targeting home buyers, sellers, and real estate agents primarily in the United States with international reach. Its business model includes property listings, agent services, home valuation tools, and seller support programs. The company benefits from a long-standing brand reputation since 1906 and is part of Anywhere Advisors LLC. The website integrates partnerships with home warranty providers and maintains active social media channels to engage customers. The platform's comprehensive content and clear navigation support a positive user experience and strong market positioning.

Security posture

The website exhibits a mature security posture with enforced HTTPS, presence of key security headers, and no visible exposure of sensitive data or vulnerable libraries. The use of consent management tools indicates attention to privacy compliance. However, the absence of a dedicated security policy page, incident response contact information, and vulnerability disclosure mechanisms suggests areas for improvement. The current security measures provide a solid foundation but could be enhanced by formalizing security governance and transparency to users.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  4. Enhance accessibility features to meet or exceed standards for all users.
  5. Maintain and communicate clear data retention and privacy practices aligned with GDPR and other regulations.

Technical notes

Notes

The website is built on a modern technology stack including React and Next.js frameworks, supported by Material UI for consistent design. It uses Directus as a CMS backend and integrates analytics and marketing tools such as Google Tag Manager, Datadog, and LaunchDarkly. The site demonstrates fast loading times, responsive design, and good SEO practices. Technical debt appears minimal, with opportunities to further optimize accessibility and security transparency. Hosting provider details are not explicit, but performance and uptime indicators suggest a reliable infrastructure.
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.
