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 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

GAP Ltd holds a strong market position in the manufacturing and retail sectors of uPVC building products. Their competitive advantage lies in their extensive depot network, product range, and trade-focused services. The business model combines manufacturing with distribution and online sales, targeting installers, builders, and contractors. The company shows growth through new depot openings and partnerships, supported by a consistent brand and multiple industry certifications. Their marketing ecosystem includes Google Ads, VWO for optimization, and Klaviyo for email marketing, indicating a strategic approach to customer engagement and retention.

Security posture

The website employs HTTPS with good SSL configuration and integrates Google Consent Mode to manage user data privacy. Security best practices observed include cookie consent mechanisms and denial of ad and analytics storage by default until consent is given. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident, and no dedicated security or incident response pages are found. No vulnerabilities or exposed sensitive data were detected in the provided content. The security posture is solid but could be enhanced by adopting additional security headers and publishing formal security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Ensure all forms include anti-CSRF tokens and robust input validation to prevent injection attacks.
  5. Enhance accessibility features and provide detailed data retention policies to strengthen privacy compliance.

Technical notes

Notes

The website utilizes a modern technology stack including Google Analytics, Google Tag Manager, Visual Website Optimizer for A/B testing, jQuery, Swiper.js for sliders, and Toastr.js for notifications. The site is built on a responsive design framework, likely Bootstrap, ensuring good mobile optimization. Performance is moderate with asynchronous script loading and deferred resources. The site lacks explicit CMS identification, suggesting a custom or proprietary platform. Technical debt appears low, with opportunities for improvement in accessibility and SEO metadata completeness.
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.
