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

MTEL Austria is a telecommunications provider offering a range of services including mobile tariffs, internet, and TV entertainment packages primarily targeting private and business customers in Austria. The company is part of the Telekom Serbien Group, indicating a solid regional market presence. The website is professionally designed with good content quality, clear navigation, and mobile optimization. It leverages modern JavaScript libraries and integrates marketing and analytics tools such as Google Tag Manager, Hotjar, and Cookiebot for consent management. However, the site currently lacks a valid SSL certificate and does not serve content over HTTPS, which is a critical security shortfall. Security headers are properly configured, but the absence of HTTPS and modern TLS protocols significantly lowers the security posture. Privacy and cookie policies are comprehensive and GDPR compliant, with a consent mechanism in place. Contact information including email and phone numbers is clearly provided, enhancing business credibility. Overall, the website is functional and professional but requires urgent security improvements to protect user data and build trust.

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

6 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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

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 Austria operates in the telecommunications sector with a medium-sized business model focused on providing mobile, internet, and TV services. Its affiliation with Telekom Serbien Group strengthens its market position and brand trust. The company targets both private consumers and business clients, offering prepaid and postpaid tariffs, device sales, and entertainment content. The website reflects a mature digital presence with multi-language support and integration of social media channels. The business ecosystem includes sister domains in neighboring countries, indicating a regional expansion strategy. The absence of explicit security policies or certifications on the site suggests room for improvement in transparency and compliance communication.

Security posture

The website demonstrates basic security hygiene through the use of security headers like X-Frame-Options, Content-Security-Policy, X-XSS-Protection, and X-Content-Type-Options. However, the lack of a valid SSL certificate and disabled TLS protocols is a critical vulnerability that exposes users to data interception and undermines trust. No HSTS or OCSP stapling is configured, and session resumption is disabled, indicating outdated SSL/TLS configuration. No explicit incident response or vulnerability disclosure policies are found, which could hinder timely security issue management. The site uses secure cookies with HttpOnly and Secure flags, which is positive. Overall, the security posture is weak and requires immediate remediation to meet industry standards and regulatory requirements.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Configure OCSP stapling to improve certificate revocation checking performance and security.
  5. Develop and publish a clear security policy and vulnerability disclosure program.
  6. Regularly audit third-party libraries and update them to mitigate vulnerabilities.
  7. Enhance accessibility features to improve compliance and user experience.
  8. Consider adding structured data (JSON-LD) for business and contact information to improve SEO and trust.
Technical notes

Notes

The website is built on a modern frontend stack using Bootstrap 4, jQuery, and various carousel and animation libraries (Owl Carousel, Slick Carousel, AOS). It integrates third-party services such as Google Tag Manager, Cookiebot for consent management, Hotjar for analytics, and Tawk.to for live chat support. The site uses nginx as the web server. Despite the modern frontend technologies, the lack of HTTPS and poor SSL configuration is a major technical risk. Performance metrics are not available, but the presence of multiple large image banners and external scripts may impact load times. The site is mobile optimized with responsive design and language localization. No CMS or backend platform is explicitly detected. DNS records show professional email setup via Outlook protection. Overall, the technical infrastructure is adequate but requires security upgrades and performance optimization.
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.
