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

    • 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

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, targeting both home users and businesses. Its business model revolves around providing bundled telecom services including internet, TV, and mobile plans without long-term contracts. The company leverages its parent company Hrvatski Telekom's infrastructure and brand reputation. The website's content and linked partner domains indicate a mature ecosystem with customer support portals, recruitment sites, and value-added services like Jumbo file sharing. The presence of multiple contact channels and clear policy documents suggests a customer-centric approach. Market positioning is solid as a large player in the Croatian telecom market with a focus on innovation and customer experience.

Security posture

The website demonstrates a good security posture with HTTPS enforced and integration of Google reCAPTCHA v3 to mitigate automated abuse. Cookie consent is implemented with granular user controls, supporting GDPR compliance. No sensitive data is exposed in the HTML content. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not visibly configured, which could be improved to enhance protection against common web attacks. There is no publicly available security policy or vulnerability disclosure program, which limits transparency in incident response readiness. Overall, the site is secure but could benefit from enhanced header configurations and published security practices.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a clear security policy and vulnerability disclosure page to improve transparency and encourage responsible reporting.
  3. Provide incident response contact channels such as security@ or abuse@ email addresses to facilitate communication.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance user education on privacy and security through visible notices and best practice guidelines.

Technical notes

Notes

The website is built on the eZ Publish CMS platform powered by Netgen, utilizing modern JavaScript libraries including jQuery and Bootstrap for responsive design and interactivity. It integrates Google Tag Manager for analytics and Google reCAPTCHA for bot protection. SnapEngage chat and PushPushGo notifications are used for customer engagement and marketing. The site is mobile-optimized with good accessibility features such as ARIA roles and keyboard navigation support. Performance is moderate with asynchronous loading of scripts and optimized images. Hosting and domain registration are managed by Hrvatski Telekom d.d., ensuring reliable infrastructure. Opportunities exist to improve security headers and streamline some legacy code for enhanced performance and security.
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.
