Sealrite Limited is a UK-based specialist company focused on the repair, maintenance, and replacement of industrial valves and pumps, serving primarily industrial and commercial clients. Established in 2005, the company offers a range of services including valve repairs, pump repairs, gland packing, mechanical seals, materials handling, electrical engineering, and fabrication engineering. The website reflects a professional and consistent brand image with clear service offerings and contact information, positioning Sealrite as a trusted specialist in its niche market. The technical infrastructure of the website is built on WordPress using the Divi theme, enhanced with Yoast SEO for search optimization and Google reCAPTCHA for form security. The site is hosted by Ionos SE and employs modern web technologies including HTTPS with strong SSL configuration, security headers, and cookie consent mechanisms, indicating a mature digital presence. Performance and mobile optimization are good, though accessibility features could be improved. From a security perspective, the website demonstrates good practices such as HTTPS enforcement, security headers, and use of CAPTCHA to protect forms. However, it lacks explicit security policies, incident response contacts, and vulnerability disclosure mechanisms, which are recommended for enhanced security posture and compliance. No vulnerabilities or suspicious patterns were detected in the analysis. Overall, Sealrite Limited's website is professional, secure, and compliant with GDPR, providing a trustworthy online presence for its industrial services. Strategic recommendations include adding a security policy page, implementing a vulnerability disclosure program, enhancing accessibility, and publishing terms of service to further strengthen trust and compliance.

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

5 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 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

Sealrite Limited operates in the manufacturing sector, specializing in industrial valve and pump repair services. The company targets industrial clients requiring maintenance and repair of boilers, pumps, and pipework distribution systems. Its business model is service-oriented, focusing on technical expertise and engineering solutions. The domain age and registration data support the company's established market presence since 2005. The website's clear service segmentation and professional presentation suggest a stable market position with potential for growth in industrial maintenance sectors. The absence of partner or subsidiary domains indicates a focused standalone operation. Marketing efforts include SEO optimization and Google Analytics tracking, supporting data-driven business decisions.

Security posture

The website exhibits a solid security posture with HTTPS enabled and well-configured SSL certificates. Security headers such as Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, and Content-Security-Policy are present, enhancing protection against common web attacks. The use of Google reCAPTCHA on forms mitigates automated abuse. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure mechanisms represents gaps in transparency and readiness. No exposed sensitive data or vulnerable libraries were detected. GDPR compliance is supported by a comprehensive privacy policy and cookie consent mechanism. Overall, the security maturity is good but can be improved by formalizing security governance and incident response information.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Add incident response contact information such as security@ or abuse@ email addresses.
  4. Enhance website accessibility to meet WCAG standards for broader user inclusivity.
  5. Consider publishing terms of service to clarify user agreements and legal protections.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Divi theme, which provides a flexible and visually appealing design. The integration of Yoast SEO indicates attention to search engine optimization best practices. JavaScript libraries include jQuery and Google reCAPTCHA for enhanced interactivity and security. Hosting by Ionos SE is consistent with the domain registrar, suggesting streamlined management. Performance is moderate with room for optimization, particularly in loading times and accessibility features. The site is mobile optimized with responsive design elements. Technical debt appears low, but ongoing updates and security patches are recommended to maintain stability and security.
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.
