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. 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

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

  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

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 focuses on consumer telecommunications services, offering mobile devices and plans, internet, and TV packages. The business model is service-oriented with direct consumer sales and online ordering. The website integrates multiple marketing and analytics tools, suggesting active customer engagement and data-driven marketing. The WHOIS data confirms legitimate ownership and domain age consistent with the company's operational history. No suspicious domains or partners were identified. The company appears to be a large entity in the telecommunications sector in Croatia.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA to protect forms, indicating good baseline security. However, no explicit security policies, incident response contacts, or vulnerability disclosure information are published. Security headers are not explicitly detected in the HTML snapshot. The use of multiple third-party analytics and marketing scripts increases the attack surface but is common for commercial sites. No vulnerabilities or exposed sensitive data were detected in the content. Overall, security posture is good but could be improved with published policies and enhanced headers.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve privacy compliance.
  2. Add explicit security headers such as Content Security Policy, X-Frame-Options, and HSTS.
  3. Provide a public security policy and incident response contact information.
  4. Implement and publish a vulnerability disclosure or security.txt file.
  5. Regularly audit third-party scripts to minimize security risks and improve performance.

Technical notes

Notes

The website is built on Liferay CMS with a modern tech stack including Google Analytics, Microsoft Clarity, and Visual Website Optimizer for analytics and A/B testing. The site uses asynchronous script loading and CDN-hosted resources for performance. Mobile optimization is good, and SEO meta tags are properly set. Some technical debt is indicated by the large number of scripts and complex integrations, which may impact load times. Accessibility features are basic but present. Hosting appears stable and likely managed by the company or a trusted provider.
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.
