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

4 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

      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 as an essential enterprise entity, serving a broad customer base in Sweden. Its business model revolves around providing mobile, broadband, and TV services, supported by a strong brand presence and sustainability credentials. The company leverages partnerships and advanced marketing tools like Optimizely for analytics and user experience optimization. The website's clear navigation and comprehensive service offerings indicate a customer-centric approach. Telia's market position is strong, supported by its extensive network infrastructure and reputation. The absence of direct WHOIS data for the www subdomain is not unusual and does not impact the company's credibility.

Security posture

The website demonstrates a solid security posture with HTTPS, strict security headers, and no visible vulnerabilities or exposed sensitive data. The cookie consent mechanism is well-implemented, supporting privacy compliance. However, the absence of a dedicated security policy page and incident response contact information suggests areas for improvement. No vulnerability disclosure or security.txt files were found, which could enhance transparency and trust. Overall, the security maturity is high, with recommendations to formalize security policies and incident response channels to further strengthen the posture.

Recommendations

  1. Publish a dedicated security policy page to inform users about security practices.
  2. Provide explicit incident response contact details such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance accessibility features to improve inclusivity and compliance.
  5. Regularly review and audit third-party scripts and tracking tools for security risks.

  5. Use of modern web technologies and frameworks.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring server-side rendering and fast load times. The use of WOFF2 fonts and optimized images contributes to performance. The site is mobile-optimized with responsive design and accessibility considerations. SEO is supported by proper meta tags and Open Graph data. No CMS was explicitly detected, suggesting a custom or headless approach. Hosting provider details were not identified from the HTML content. The technical implementation is robust, with opportunities to improve documentation of security policies and incident response mechanisms.
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.
