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

The website for upc.at, branded as Magenta Austria, represents a major telecommunications provider offering a wide range of services including mobile tariffs, internet packages, TV offerings, and bundled solutions for both consumers and business customers. The site is professionally designed with rich content, clear navigation, and consistent branding that aligns with the corporate identity of T-Mobile Austria GmbH. Structured data and social media presence further reinforce the company's legitimacy and market position in Austria. Technically, the site is built on Adobe Experience Manager CMS and utilizes modern marketing and analytics tools such as Google Tag Manager and Usercentrics for consent management. However, the website currently suffers from a critical security issue: the SSL/TLS certificate is invalid or missing, and no secure HTTPS protocols are enabled. This significantly impacts the security posture and user trust, despite the presence of security headers and content security policies. Privacy compliance is well addressed with clear privacy and cookie policies and an active consent mechanism. Contact information is available primarily via phone numbers and contact forms, though no direct company email addresses are exposed. The WHOIS data confirms the domain's legitimacy and consistency with the business identity. Overall, while the website excels in content quality, user experience, and privacy compliance, the lack of valid HTTPS and proper SSL configuration is a critical vulnerability that must be addressed immediately to ensure secure communications and maintain customer 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Magenta Austria operates as a leading telecommunications provider in Austria, targeting both private consumers and business clients. Their business model revolves around offering comprehensive telecommunications services including mobile plans, internet connectivity, TV packages, and combined offers. The company leverages strong brand recognition and a broad service portfolio to maintain a competitive market position. The website reflects a mature digital presence with extensive product offerings, promotional campaigns, and customer engagement tools. Partnerships with device manufacturers like Samsung and Apple are evident, enhancing their product ecosystem. The use of advanced CMS and marketing technologies indicates a strategic investment in digital transformation and customer experience.

Security posture

The current security posture of the website is weak due to the absence of a valid SSL/TLS certificate and disabled HTTPS protocols, exposing users to potential risks such as data interception and man-in-the-middle attacks. While security headers like HSTS, Content Security Policy, and X-Content-Type-Options are present, their effectiveness is undermined by the lack of HTTPS. No vulnerabilities such as Heartbleed or POODLE are detected, but the missing encryption is a critical flaw. Incident response and security policies are not publicly documented on the site, which could be improved to enhance transparency and readiness. Immediate remediation of SSL issues is essential to protect user data and comply with security best practices.

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. Configure strong cipher suites and enable OCSP stapling for improved security and performance.
  4. Activate HSTS with includeSubDomains and preload flags to enforce HTTPS usage.
  5. Publish clear security and incident response policies to improve transparency and trust.
  6. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.
  7. Enhance contact information visibility with verified company emails for security and support.
  8. Maintain and improve privacy compliance with clear data retention and user rights information.
Technical notes

Notes

The website is built on Adobe Experience Manager CMS, leveraging jQuery and AngularJS frameworks. It integrates Google Tag Manager and Usercentrics for analytics and consent management. The site is mobile-optimized with responsive design and accessibility features. However, performance metrics are missing or zero, indicating potential issues with load time measurement or optimization. The SSL configuration is currently invalid, and no TLS protocols or cipher suites are enabled, which is a critical technical deficiency. The site uses multiple external domains for analytics, advertising, and social media integration. Overall, the technical infrastructure is modern but requires urgent security upgrades and performance monitoring.
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.
