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

Slovenský hydrometeorologický ústav (SHMÚ) is the official Slovak government institute responsible for meteorological, hydrological, climatological, and air quality services. The website serves as a comprehensive portal providing real-time weather data, forecasts, warnings, and scientific information targeted at the general public, researchers, and environmental professionals. It holds a strong market position as the authoritative national source for weather and environmental data in Slovakia. Technically, the website uses modern JavaScript libraries such as jQuery and integrates Google Tag Manager and Facebook SDK for analytics and marketing, all implemented with user consent mechanisms. The site is well-structured, accessible, and optimized for performance and SEO, reflecting a mature digital infrastructure. Security posture is solid with HTTPS enforced and basic security headers present, though there is room for improvement in advanced security policies and incident response transparency. Overall, the website is trustworthy, professionally maintained, and compliant with GDPR and cookie regulations.

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

7 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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';…

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

SHMÚ operates as a government entity providing essential environmental monitoring and forecasting services. Its business model is non-commercial, focused on public service and scientific research. The institute benefits from partnerships with international organizations such as WMO and ECMWF, enhancing its credibility and data quality. The website's content and services cater to a broad audience including citizens, educational institutions, and governmental bodies. The presence of certifications and official documents supports its authoritative role. The partnership ecosystem includes media, research institutes, and public health authorities, indicating a well-integrated operational network. Growth indicators include active publication of scientific updates and engagement with the community through seminars and educational content.

Security posture

The website demonstrates a mature security posture with HTTPS encryption and cookie consent mechanisms that respect user privacy. Basic security headers are implemented, but advanced headers like Content Security Policy are absent, representing an area for enhancement. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a published security policy, incident response plan, or vulnerability disclosure mechanism limits transparency and readiness for security incidents. The integration of third-party analytics is managed with consent, reducing privacy risks. Overall, the security maturity is good but could be improved by formalizing security governance and incident response communications.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website to improve transparency and user trust.
  2. Implement a security.txt file to facilitate responsible vulnerability disclosure.
  3. Add advanced HTTP security headers such as Content Security Policy (CSP) to mitigate cross-site scripting and other attacks.
  4. Regularly audit and update third-party scripts to ensure no vulnerabilities are introduced.
  5. Enhance contact information with explicit security and abuse reporting channels.

Technical notes

Notes

The website uses a stable and modern technology stack including jQuery 3.7.1 and cookie consent management scripts. Google Tag Manager and Facebook SDK are integrated for analytics and marketing purposes with user consent. The HTML is well-structured with appropriate meta tags for SEO and accessibility features such as ARIA roles and skip links. Performance is optimized with preloading fonts and DNS prefetching for external resources. The site is mobile-friendly and accessible, with clear navigation and content hierarchy. There is no detected CMS, suggesting a custom or government-managed platform. Hosting details are not explicit but the site is served securely over HTTPS with good response times. Opportunities exist to modernize security headers and enhance incident response readiness.
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.
