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

ZooplaValuations.co.uk is an online property valuation tool operated by Blue Spark Limited, established in 2018. The website offers users the ability to estimate property values by entering postcode and property details, targeting UK property owners and sellers. The platform integrates Zoopla data, indicating a partnership or data source relationship, and uses modern web technologies including Vue.js and Google services for analytics and bot protection. The site is functional but minimalistic, lacking comprehensive privacy, cookie, or terms of service policies, and does not provide direct contact information. Security measures include Google reCAPTCHA, but no advanced HTTP security headers were detected, and no vulnerability disclosure or incident response information is available. Overall, the site demonstrates a moderate level of technical maturity but requires improvements in privacy compliance and security transparency to enhance trust and regulatory adherence.

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

10 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 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';…

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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 business operates in the Real Estate sector, focusing on providing online valuation services leveraging Zoopla's property data. Its small size and niche market position suggest a targeted service model aimed at UK property owners seeking quick valuation insights. The lack of visible contact details and policies may limit user trust and regulatory compliance. The partnership with Zoopla is a key competitive advantage, providing credible data sources. The business model appears to be service-oriented, possibly generating leads or data for further real estate services. Growth potential depends on expanding service transparency, compliance, and user engagement.

Security posture

The website employs basic security practices such as HTTPS and Google reCAPTCHA to mitigate automated abuse. However, the absence of security headers like Content Security Policy (CSP), HSTS, and X-Frame-Options reduces its defense-in-depth posture. No explicit privacy or cookie policies are published, indicating compliance gaps with GDPR and related regulations. The lack of incident response contact channels and vulnerability disclosure mechanisms further limits security readiness. While no critical vulnerabilities were detected in the HTML content, the site would benefit from enhanced security configurations and transparency to reduce risk and improve user trust.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Provide clear contact information including security incident response channels.
  4. Introduce a security.txt file or vulnerability disclosure policy to encourage responsible reporting.
  5. Enhance accessibility and SEO metadata to improve user experience and search visibility.

Technical notes

Notes

The website is built using modern JavaScript frameworks, likely Vue.js, and integrates Google Analytics and reCAPTCHA for tracking and security. The HTML and CSS are valid and the site appears mobile-optimized with responsive design elements. Performance is moderate with asynchronous loading of scripts. However, the site lacks advanced SEO metadata and accessibility features. There is no detected CMS or hosting provider information from the HTML content. The technical stack is appropriate for a small online service but could be improved with better security headers and privacy compliance mechanisms.
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.
