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, hydrological information, and air quality monitoring. It targets a broad audience including the general public, government agencies, researchers, and educational institutions. SHMÚ holds a strong national market position as the authoritative source for environmental data in Slovakia. Technically, the website employs modern web technologies including jQuery, Google Tag Manager, Google Analytics, and Facebook SDK for analytics and marketing. It features a cookie consent mechanism compliant with GDPR, and the site is well-structured with good accessibility and SEO practices. Performance is optimized with deferred script loading and prefetching. From a security perspective, the site uses HTTPS and implements cookie consent but lacks explicit security headers and a public security policy or incident response information. No vulnerabilities or exposed sensitive data were detected. WHOIS data confirms the legitimacy of the domain with consistent registrant information matching the official institute. Overall, the website is professional, trustworthy, and compliant with privacy regulations, though it could improve by publishing explicit security policies and adopting additional security headers. The risk level is low, and the site effectively supports its mission as a government environmental data provider.

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

6 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

    • 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

  2. 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 meteorological and hydrological services in Slovakia. Its competitive advantage lies in its official status, comprehensive data offerings, and partnerships with international organizations such as WMO and ECMWF. The business model is service-oriented, funded by government budgets, focusing on public safety, environmental monitoring, and research support. The website supports multiple user segments including citizens, researchers, and policymakers. Growth indicators include continuous updates, new monitoring tools, and active communication of climate and weather events. The partnership ecosystem is robust, involving national ministries, research institutes, and international meteorological bodies.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and cookie consent mechanisms in place, reflecting GDPR compliance. However, it lacks explicit security headers like Content Security Policy and HSTS, which could enhance protection against common web attacks. No incident response or vulnerability disclosure information is publicly available, which is a gap in transparency and preparedness. The absence of security.txt reduces ease of vulnerability reporting. Overall, the site is secure for general use but could benefit from enhanced security policies and headers to align with best practices and regulatory frameworks such as NIS2.

Recommendations

  1. Implement and publish a formal security policy and incident response page to improve transparency and preparedness.
  2. Add security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen web security.
  3. Create and publish a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Enhance monitoring and auditing of third-party scripts to minimize potential vulnerabilities from external libraries.
  5. Regularly review and update privacy and cookie policies to maintain compliance with evolving GDPR and related regulations.

Technical notes

Notes

The website uses a modern and lightweight technology stack centered on jQuery 3.6.0, Google Tag Manager, and analytics tools from Google and Facebook. It employs deferred script loading and DNS prefetching to optimize performance. The HTML is well-structured with accessibility features such as ARIA roles and skip links. SEO is supported by meta tags including keywords and descriptions. The site is mobile-optimized with responsive design elements. No CMS or hosting provider is explicitly identified. Performance is fast with minimal loading delays. Technical debt appears low, but opportunities exist to adopt modern JavaScript frameworks and improve security headers for enhanced robustness.
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.
