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

ZFA Group is a modern property management company operating primarily in London and Dublin, offering services such as guaranteed rent, free maintenance, tenant sourcing, and hospitality management. The company positions itself as a trusted and fast-growing player in the residential asset management sector, managing over 1,300 properties valued at approximately £500 million. Their website reflects a professional business with clear service offerings and customer testimonials, targeting landlords and tenants seeking reliable property management solutions. Technically, the website employs a modern front-end stack including jQuery, Bootstrap, Google Analytics, and Google Tag Manager, with asynchronous script loading to optimize performance. The site is mobile responsive and SEO optimized, though accessibility features are basic. The absence of a CMS or hosting provider information limits deeper infrastructure insights. Performance is moderate, with room for improvement in accessibility and security headers. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks visible security headers such as Content-Security-Policy or X-Frame-Options. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of privacy and cookie policies and no incident response contact details indicate gaps in compliance and security transparency. The WHOIS data is missing, which raises concerns about domain registration legitimacy despite the professional website presence. Overall, the website is functional and professional but would benefit from enhanced security practices, privacy compliance, and domain registration transparency to improve trustworthiness and reduce risk exposure.

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. 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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

ZFA Group operates in the real estate and hospitality sectors, focusing on property management services with a unique selling proposition of guaranteed rent and free maintenance. Their market positioning as a fast-growing company with government contract experience provides competitive advantage and credibility. The business model revolves around managing rental properties for landlords, ensuring rent payments, and maintaining property standards. Their target customers are landlords and tenants in London and Dublin, with a growth strategy likely based on expanding property portfolios and service offerings. The partnership with Adeo Group for web design indicates a professional approach to digital presence. The absence of detailed financial or founding year data limits deeper business intelligence insights.

Security posture

The current security posture is moderate. The website enforces HTTPS and uses modern analytics tools with asynchronous loading, reducing some risk vectors. However, the lack of security headers and absence of privacy and cookie policies indicate incomplete security and compliance implementation. No incident response or abuse contact information is provided, which is a gap in readiness for security incidents. The missing WHOIS data is a significant concern, potentially indicating domain registration or privacy issues that could affect trust. Overall, while no critical vulnerabilities are evident, improvements in security headers, privacy compliance, and domain transparency are recommended to enhance security maturity.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  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. Publish incident response and abuse contact information to improve transparency and readiness.
  4. Investigate and resolve the missing WHOIS data issue to ensure domain registration legitimacy and improve trust.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a modern front-end technology stack including jQuery, Bootstrap 4, Font Awesome, and Slick Slider for UI components. Google Analytics and Google Tag Manager are integrated for tracking and marketing purposes. The site loads scripts asynchronously to optimize performance and uses Google Maps API for location features. The HTML structure is valid with proper meta tags for SEO and social sharing (Open Graph). However, no CMS or hosting provider information is evident. Performance is moderate with good mobile responsiveness but basic accessibility. There is an opportunity to improve security headers and privacy compliance to reduce technical debt and enhance overall site robustness.
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.
