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. 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
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  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

Tele2 holds a strong market position in Estonia's telecommunications sector, targeting both private and business segments with a broad portfolio of services including mobile plans, wireless internet, and TV packages. The business model is service-oriented with additional revenue streams from device sales via an e-commerce platform. The company leverages partnerships with major advertising and analytics providers to optimize marketing efforts. The domain age and registration data align with the company's established presence since 2010. The website content and structure support customer engagement and self-service, indicating a focus on customer experience and operational efficiency.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and no exposed sensitive data in the HTML content. Cookie consent is granular and transparent, supporting GDPR compliance. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident in the provided data and should be verified and implemented if missing. No incident response or vulnerability disclosure information is found, which could be improved to enhance security readiness. The use of multiple third-party scripts necessitates ongoing monitoring for vulnerabilities. Overall, the security posture is solid but could benefit from enhanced header policies and published incident response procedures.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear terms of service page to improve legal transparency.
  3. Establish and publicize a vulnerability disclosure policy and incident response contact information.
  4. Enhance accessibility features to meet higher compliance standards.
  5. Regularly audit third-party scripts and marketing tools for security and privacy compliance.

Technical notes

Notes

The website is built using Next.js, a React-based framework, indicating a modern and scalable technical infrastructure. Integration with Google Tag Manager, Exponea, Genesys, and Cookiebot shows a mature approach to analytics, marketing automation, customer engagement, and privacy compliance. Performance is moderate with multiple CSS and JS chunks loaded asynchronously, supporting good user experience. Mobile optimization is good with responsive design elements. No CMS is explicitly detected, suggesting a custom or headless architecture. Hosting provider details are not explicit but domain registration and DNS data show stable and consistent management. Opportunities exist to improve accessibility and security header implementation.
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.
