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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 company targets a broad general audience interested in weather information, including individuals planning daily activities, travelers, and outdoor enthusiasts. Revenue streams primarily come from advertising networks such as Google Ad Manager and Hubvisor, supplemented by subscription services for streaming weather videos. The partnership ecosystem includes regional weather sites and advertising technology providers. The business model leverages free content to attract high traffic volumes, monetized through targeted advertising and data-driven marketing tools. Growth indicators include extensive use of modern analytics and marketing platforms, as well as GDPR-compliant consent management. The company demonstrates a mature digital presence with consistent branding and a focus on user engagement through community features and multimedia content.

Security posture

The website exhibits a mature security posture with HTTPS enforced and integration of a consent management platform to comply with GDPR. Security best practices observed include asynchronous loading of scripts to reduce attack surface and no visible exposure of sensitive data in the HTML source. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy are not clearly documented in the provided data and should be verified. The lack of WHOIS transparency is a security concern, as it impedes verification of domain ownership and legitimacy. No immediate vulnerabilities or malware indicators were detected. Incident response and vulnerability disclosure mechanisms are not publicly evident, suggesting room for improvement in security governance and transparency.

Recommendations

  1. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy to enhance protection against common web attacks.
  2. Publish a security.txt file and provide clear incident response contact information to improve vulnerability disclosure and response readiness.
  3. Conduct regular audits of third-party scripts and advertising technologies to mitigate risks from external dependencies.
  4. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.
  5. Address the lack of WHOIS data by ensuring domain registration information is accurate and publicly available to strengthen trust and legitimacy.

Technical notes

Notes

The website uses a modern JavaScript-heavy architecture with asynchronous script loading to optimize performance. Key technologies include Google Tag Manager, Google Publisher Tags for advertising, Hubvisor for ad management, and AppConsent for GDPR compliance. The site leverages IntersectionObserver for lazy loading and Leaflet.js for interactive maps. Performance is moderate with good mobile optimization and SEO practices. The absence of a detected CMS suggests a custom or proprietary platform. Hosting provider details are not evident. The technical stack is robust but could benefit from enhanced accessibility and explicit security header implementation. The extensive use of third-party ad and tracking services necessitates ongoing security and privacy monitoring.
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.
