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

Telia Company is a major telecommunications provider focused on delivering better connected living experiences. The website reflects a modern digital presence with a React-based single-page application architecture and integrates industry-standard privacy compliance tools such as OneTrust for cookie consent management. The company targets both consumers and businesses with telecommunications and connectivity services. The site demonstrates good mobile optimization and accessibility features, although content depth and navigation clarity could be improved. From a security perspective, the website employs a robust cookie consent mechanism and uses reputable third-party analytics and marketing tools. However, there is a lack of explicit security headers and no visible security or incident response policies, which are areas for improvement. The WHOIS data confirms the legitimacy and consistency of the domain registration with the company's identity, supporting a high trust level. Overall, the website is professionally designed and compliant with GDPR requirements, but it would benefit from enhanced security practices and more transparent contact and policy information to strengthen user trust and security posture.

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

3 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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

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 Company holds a strong market position as a telecommunications enterprise, offering connectivity and related services. The business model revolves around providing telecommunications infrastructure and services to a broad audience. The company leverages partnerships with analytics and privacy compliance providers to enhance its digital operations. While the website does not expose detailed business intelligence data such as revenue streams or subsidiaries, the presence of advanced cookie consent and analytics tools indicates a mature approach to customer data management and marketing. The lack of direct contact information on the main site suggests a focus on centralized customer service channels possibly hosted elsewhere.

Security posture

The current security posture shows moderate maturity. The use of OneTrust for cookie consent and the presence of secure external scripts indicate awareness of privacy and security best practices. However, the absence of security headers, vulnerability disclosure mechanisms, and explicit incident response contacts are notable gaps. No exposed sensitive data or vulnerable libraries were detected in the provided content. The site uses HTTPS as implied by external script URLs, but SSL configuration details are not available. Enhancing security headers and publishing security policies would improve the overall security maturity and compliance.

Recommendations

  1. Implement and configure standard security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance navigation and content clarity to improve user experience and trust.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built as a modern single-page application likely using React, supported by JavaScript bundles and CSS files. It integrates OneTrust for cookie consent management and uses Google Tag Manager and Decibel Insight for analytics and tracking. The site demonstrates good mobile responsiveness and accessibility features. Performance is moderate, with potential improvements in loading speed and SEO optimization. Hosting provider details are not explicitly available. The technical stack is contemporary but could benefit from additional security hardening and performance tuning.
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.
