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

8 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. 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 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

Telekom Slovenije holds a leading market position in the Slovenian telecommunications sector, offering comprehensive communication services. The company targets a wide audience including individual consumers and enterprises. Its business model is based on providing telecommunication infrastructure and services, supported by a strong brand presence and digital engagement via social media platforms. The website's integration of analytics and marketing tools indicates a mature digital marketing strategy. The absence of explicit privacy and security policies on the site suggests an opportunity to strengthen compliance and customer trust. The company appears to maintain a stable and consistent online presence aligned with its corporate identity.

Security posture

The website employs HTTPS and a cookie consent mechanism, indicating baseline security and privacy awareness. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and absence of a published security policy or incident response contact reduces the overall security maturity. No vulnerabilities or exposed sensitive data were detected in the provided content. The company would benefit from publishing a vulnerability disclosure policy or security.txt file and enhancing transparency around incident response. Overall, the security posture is moderate but could be improved to meet higher compliance standards such as GDPR and NIS2.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Implement and publish a security policy including incident response contacts and vulnerability disclosure guidelines.
  3. Add security headers (Content-Security-Policy, X-Frame-Options, Strict-Transport-Security) to improve protection.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Increase transparency on data retention policies and user data handling to strengthen GDPR compliance.

Technical notes

Notes

The website is built using the Angular framework, indicating a modern single-page application architecture. It uses Google Tag Manager and Hotjar for analytics and user behavior tracking, and CookieYes for cookie consent management. The site loads custom fonts and uses Swiper for carousels, showing attention to design and interactivity. Performance is moderate with good mobile optimization. SEO is supported by proper meta tags and structured data in JSON-LD format. However, no CMS or hosting provider information was detected. The technical stack is robust but could benefit from enhanced security configurations and accessibility improvements.
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.
