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

McCann Homes is a UK-based real estate developer specializing in stylish, contemporary homes designed for modern living. Their website showcases recent and previous developments and offers consultation booking services. The company targets home buyers and property investors seeking quality residential properties. Technically, the website is built on Squarespace, leveraging modern web technologies including embedded video content and Google Tag Manager for analytics. The site is mobile-optimized and uses HTTPS with HSTS for secure communications. However, the absence of privacy and cookie policies, lack of explicit contact information, and missing WHOIS data reduce overall trust and compliance posture. Security headers are minimal but foundational HTTPS security is in place. Overall, the website presents a professional image but would benefit from enhanced privacy compliance and clearer business contact details.

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

3 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 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

McCann Homes operates as a small real estate developer focusing on high-quality residential properties in the UK market. Their business model centers on property development and sales, supported by consultation services. The website's content and design suggest a niche market positioning emphasizing style and modern living. The company maintains a social media presence through generic Squarespace accounts, indicating potential areas for improvement in brand-specific digital marketing. The lack of detailed WHOIS data and absence of privacy policies may impact customer trust and regulatory compliance. There is no evidence of partnerships or subsidiaries from the website content.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced with HSTS enabled, ensuring encrypted communications. However, security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options are not detected, which could mitigate certain web-based attacks. No exposed sensitive data or vulnerable libraries were identified in the HTML content. The site lacks documented incident response or vulnerability disclosure policies, which are important for security maturity and customer trust. Privacy compliance is weak due to missing policies and cookie consent mechanisms. Overall, the security posture is adequate for a small business but could be significantly improved with additional security controls and compliance documentation.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  3. Publish clear contact information including company emails and phone numbers to improve business credibility and customer support.
  4. Establish and publicize an incident response and vulnerability disclosure policy to demonstrate security maturity.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used and maintain website performance.

Technical notes

Notes

The website is built on the Squarespace platform, utilizing its CDN and hosting infrastructure. It uses modern web technologies including Typekit fonts, Plyr video player for embedded videos, and Google Tag Manager for analytics. The site is responsive and mobile-optimized with a clean design and clear navigation. Performance is moderate, typical for a CMS-based site with rich media content. Accessibility features are basic, with room for improvement. SEO optimization is present but minimal, with canonical tags and Open Graph metadata included. The absence of advanced security headers and privacy compliance features represents technical debt that should be addressed to enhance security and regulatory adherence.
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.
