Security score

73/100

Risk levelMedium

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

Telia is a leading telecommunications company in Sweden, offering a broad range of services including mobile subscriptions, broadband, TV, and streaming. The website reflects a mature enterprise with a strong market position and extensive 5G network coverage. The digital presence is modern, leveraging Next.js and React frameworks, with a focus on user experience and mobile optimization. Privacy and cookie consent mechanisms are well implemented, indicating compliance with GDPR regulations. Security posture is strong with HTTPS enforced and appropriate security headers, though explicit security policy and incident response information are not publicly detailed. WHOIS data for the www subdomain is missing, likely due to domain registration practices or privacy protection, but the overall legitimacy of the site and business is high.

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

5 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

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Telia operates in the telecommunications sector targeting both private consumers and businesses in Sweden. Their business model includes selling mobile devices, subscriptions, broadband, and TV packages, with bundled offers and family plans. The company maintains a strong brand presence with consistent messaging and multiple official social media channels. Partnerships include ethics reporting platforms and payment processors. The website content and structure support a professional and trustworthy image, suitable for a large enterprise. Growth is supported by advanced 5G network deployment and digital service offerings.

Security posture

The website demonstrates a good security maturity level with HTTPS, modern security headers, and no visible vulnerabilities or exposed sensitive data. Cookie consent is actively managed via Onetrust, supporting privacy compliance. However, the absence of a dedicated security policy or vulnerability disclosure page limits transparency. Incident response contact details are not explicitly provided, which could be improved. Overall, the security posture is robust but could benefit from enhanced communication of security governance and incident handling.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and practices.
  2. Provide clear incident response contact information to improve transparency and trust.
  3. Implement and publish a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Enhance data retention policy disclosures to align with GDPR transparency requirements.
  5. Regularly review and audit third-party scripts and integrations for security and privacy compliance.

Technical notes

Notes

The website uses a modern technology stack including React and Next.js, ensuring good performance and mobile responsiveness. Fonts are optimized with WOFF2 format. Cookie consent is managed by Onetrust, and marketing/analytics tools like Optimizely are integrated. The site is well structured with semantic HTML and accessibility considerations. Performance is moderate, with potential for further optimization. Hosting provider details are not explicitly identified. Overall, the technical implementation supports a high-quality user experience and scalable infrastructure.
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.
