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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

mtel d.o.o. holds a leading position in the Montenegrin telecommunications market, offering a full suite of telecom services and devices. The company targets a wide customer base including private users and businesses, with specialized offerings such as family packages and digital services. The business model is based on subscription and device sales, supported by a strong online presence and digital marketing efforts. The company maintains active social media channels and provides extensive customer support resources. The domain age and WHOIS data confirm the company's legitimacy and long-standing market presence. No parent or subsidiary companies were identified from the data provided.

Security posture

The website employs HTTPS and integrates cookie consent mechanisms, reflecting compliance with basic security and privacy standards. However, the absence of DNSSEC, security.txt, and explicit security policies or incident response contacts indicates gaps in security maturity. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party analytics and tracking tools is extensive, which requires careful privacy management. Overall, the security posture is moderate but could be enhanced by implementing additional security headers, publishing a security policy, and enabling DNSSEC.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and provide incident response contact information on the website.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure.
  5. Review and optimize third-party tracking to enhance user privacy and GDPR compliance.

Technical notes

Notes

The website uses a combination of modern web technologies including Google Tag Manager, Facebook SDK, Hotjar, and Google Analytics for marketing and analytics purposes. The HTML structure is valid and includes responsive design elements for mobile optimization. The site uses Bootstrap components such as carousel sliders for dynamic content presentation. The CMS appears to be custom or proprietary, with no common CMS detected. Performance is moderate with good SEO practices including meta tags and Open Graph data. Accessibility features are basic and could be improved. Overall, the technical infrastructure supports a professional and user-friendly experience but could benefit from enhanced accessibility and security configurations.
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.
