The domain registration data aligns well with the business history and legitimacy, reinforcing trustworthiness. From a security perspective, the site employs HTTPS with strong SSL configuration and follows best practices in protecting user data and corporate information.

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

Business profile

OpenWeather UK operates in a competitive niche providing weather intelligence to a broad range of industries heavily impacted by weather conditions. Their business model centers on B2B services with flexible pricing plans and enterprise solutions. The company’s partnerships with national meteorological agencies and presence in over 190 countries provide a competitive advantage in data accuracy and reliability. Customer testimonials and a large user base (7 million+) indicate strong market acceptance. The company targets sectors such as energy, logistics, insurance, retail, agriculture, advertising, health, emergency services, and public authorities, reflecting a diversified client portfolio. Growth indicators include continuous product innovation, AI-driven forecasting models, and expansion of global operations. The partnership ecosystem and foundation initiatives further strengthen their market position and corporate responsibility profile.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, likely comprehensive security headers, and no visible exposure of sensitive information. The presence of a corporate security page indicates organizational commitment to confidentiality, integrity, and availability of information. However, the absence of a public incident response contact or vulnerability disclosure policy limits transparency and may impact trust among security-conscious clients. No outdated or vulnerable libraries were detected in the scripts. Tracking and analytics are implemented with consent mechanisms, supporting privacy compliance. Overall, the security maturity is high but could be improved by publishing explicit incident response and vulnerability disclosure information.

Recommendations

  1. Publish a dedicated vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  2. Provide clear incident response contact channels, such as a security@ or abuse@ email address.
  3. Enhance visible documentation of security headers and SSL/TLS configurations for transparency.
  4. Regularly audit third-party scripts and tracking tools to ensure no vulnerabilities or privacy issues.
  5. Consider appointing and publishing Data Protection Officer contact details to strengthen GDPR compliance.

Technical notes

Notes

The website is built on a modern React and Next.js framework, ensuring server-side rendering and fast page loads. The use of preloading for images and scripts optimizes performance. The site is mobile responsive with excellent design quality and accessibility features. Integration with Google Tag Manager and Leadinfo provides analytics and user tracking with privacy considerations. Hosting details are not explicitly stated but domain registration is via Namecheap, Inc. The site uses multiple external scripts for analytics and tracking but no ad networks were detected. Overall, the technical infrastructure is robust, scalable, and well-optimized for business use cases. Opportunities exist to improve technical transparency around security headers and incident response 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.
