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

A1 Srbija is a well-established telecommunications company operating in Serbia since 2012, offering mobile telephony, internet services, and device sales targeting private consumers. The website reflects a mature digital presence with professional design, good mobile optimization, and clear navigation. The company leverages multiple modern technologies including JavaScript frameworks, translation services, and marketing/tracking tools to enhance user experience and marketing reach. Security posture is solid with HTTPS enforced and cookie consent implemented, though there is room for improvement in DNS security and security headers.

Overall, the domain registration and website content are consistent and trustworthy, supporting a high legitimacy score.

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.

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 holds a strong market position as a leading mobile network operator in Serbia, focusing on private customers with prepaid and postpaid plans. Its business model combines telecommunications services with retail device sales, supported by an active online webshop. The presence of multiple advertising and tracking services indicates a strategic emphasis on digital marketing and customer engagement. Social media integration is robust, enhancing brand visibility. The company appears to operate independently without publicly listed parent or subsidiary companies. The website content and structure suggest a focus on customer service and product promotion, aligned with industry standards.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and active domain status. However, the absence of DNSSEC and security headers such as Content Security Policy or HSTS reduces the overall security maturity. No explicit security policies or incident response contacts are published, which could hinder transparency and trust in security matters. The use of multiple third-party scripts for advertising and tracking introduces potential privacy risks, though cookie consent mechanisms are in place. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Enhancing security headers and publishing clear security policies would improve the security posture significantly.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement standard security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated privacy policy and security policy page with clear GDPR compliance statements.
  4. Add a security.txt file and vulnerability disclosure policy to facilitate responsible reporting.
  5. Provide explicit incident response contact channels such as security@ or abuse@ email addresses.

Technical notes

Notes

The website uses a modern JavaScript-based tech stack with libraries such as jQuery, Swiper.js, and Weglot for multilingual support. Google Tag Manager and other tracking services are integrated for analytics and marketing. The site is served over HTTPS with a valid SSL certificate, though DNSSEC is not enabled. Performance is moderate with some optimization potential. Mobile responsiveness and accessibility are good but could be improved with enhanced ARIA roles and semantic markup. SEO practices are well implemented with meta tags, Open Graph, and JSON-LD structured data. No CMS or hosting provider details were explicitly detected. Overall, the technical infrastructure supports a professional and functional user experience.
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.
