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

Sinoptik.ua is a well-established Ukrainian weather forecasting website providing detailed weather information for over 29,000 localities in Ukraine and more than 104,000 cities worldwide. The site targets residents and visitors seeking reliable weather forecasts, offering 7-day and 10-day detailed forecasts. Its business model is primarily advertising-supported, partnering with FORECA for meteorological data. Technically, the site employs modern JavaScript frameworks and integrates multiple ad networks and tracking services, ensuring a responsive and SEO-optimized user experience. Security posture is solid with HTTPS enforced, though some security headers are missing and no explicit security policy or vulnerability disclosure is present. Privacy compliance is good with a comprehensive privacy policy, but lacks a cookie consent mechanism despite tracking scripts. Overall, the site is professional, trustworthy, and technically mature, with room for improvement in security headers and privacy transparency.

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

4 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

Sinoptik.ua holds a strong market position in Ukraine as a leading weather forecast provider with extensive geographic coverage. Its competitive advantage lies in detailed localized forecasts and partnership with FORECA. The business model relies on advertising revenue, leveraging multiple ad networks and header bidding technologies. Target customers include general public and businesses needing weather data. The site shows indicators of steady growth and digital maturity, with a consistent branding strategy and professional content. The partnership ecosystem includes FORECA and major ad platforms. Strategic observations suggest focusing on enhancing privacy compliance and security transparency to maintain user trust and regulatory alignment.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap that could be exploited. There is no public vulnerability disclosure or security.txt file, which limits incident response readiness. Privacy policy is comprehensive and GDPR compliant, but cookie consent mechanisms are missing despite use of tracking technologies, posing compliance risks. No direct contact channels for security incidents are provided. Overall, the security culture appears functional but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR and other privacy regulations.
  3. Publish a vulnerability disclosure policy or security.txt file to improve incident response and transparency.
  4. Provide direct security contact channels (e.g., security@ or abuse@ email addresses) to facilitate reporting of security issues.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with asynchronous loading of scripts to optimize performance. It integrates Google Tag Manager and Google Analytics for tracking, along with multiple advertising technologies such as Bidmatic and Adtelligent for monetization. The site is mobile-optimized and SEO-friendly with proper meta tags and structured data (JSON-LD) for enhanced search engine visibility. Performance is moderate, with potential improvements in script loading and caching. No CMS or hosting provider is explicitly identified. Technical risks include missing security headers and lack of explicit privacy consent mechanisms, which could impact compliance and security posture.
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.
