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

Iskon.hr is the official website of Iskon, a Croatian telecommunications provider offering fixed internet, television (Iskon.Play TV), and other telecom services for residential and business customers. The website presents a professional and modern design built with React and Next.js frameworks, utilizing Ant Design components. The content is relevant and targeted primarily at Croatian consumers and businesses seeking telecom solutions. However, the site lacks explicit privacy and cookie policies, which are critical for GDPR compliance and user trust. Security posture is moderate with HTTPS likely enabled but missing key security headers and no visible incident response or vulnerability disclosure information. Overall, the website is functional and credible but would benefit from enhanced privacy compliance and security 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

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. 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

      • OWASP A04:2025
      • ASVS V3.4.1

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

Iskon operates in the telecommunications sector in Croatia, providing internet and TV services to both home users and businesses. The business model focuses on bundled telecom services, including broadband internet and IPTV. The company appears well-established with a consistent domain registration and a clear market presence. The website targets Croatian customers, emphasizing fast fixed internet and business telecom solutions. The lack of visible contact emails and detailed company registration data on the site limits direct business transparency but the presence of a dedicated info phone number supports customer engagement. The use of Google Tag Manager indicates active marketing and analytics efforts.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is presumably enabled, but no security headers such as Content-Security-Policy or X-Frame-Options were detected in the provided data. There is no published security policy, incident response plan, or vulnerability disclosure mechanism, which are important for managing security risks and compliance. The absence of privacy and cookie policies also indicates gaps in GDPR compliance. No exposed sensitive data or vulnerable libraries were identified in the HTML content. Overall, the security maturity is average, with room for improvement in transparency and technical safeguards.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement and configure security headers to enhance protection against common web attacks.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  5. Enhance transparency by including company registration and legal information on the website.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, with Ant Design UI framework for consistent styling. The site loads multiple asynchronous JavaScript chunks, indicating a modular and performant architecture. Google Tag Manager is used for analytics and marketing tracking. The site appears mobile optimized with responsive design. However, no CMS or hosting provider information was detected. Performance is moderate, with potential for optimization in loading times and accessibility features. The absence of security headers and privacy compliance mechanisms represents technical debt that should be addressed to improve security and regulatory adherence.
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.
