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

Telia.fi is the corporate website for Telia Company’s business segment in Finland, offering a broad range of telecommunications and ICT services tailored for enterprises and public sector customers. The site highlights key offerings such as mobile subscriptions, devices, IT services, network solutions, security, cloud, IoT, and consulting services, positioning Telia as a leading and comprehensive ICT partner in the Finnish market. The website is professionally designed with consistent branding and good content quality, targeting Finnish-speaking business customers with language options for English and Swedish. Technically, the site uses Magnolia CMS, is hosted on Sonera/Telia infrastructure, and employs modern analytics and marketing tools including Datadog RUM, Google Tag Manager, OneTrust for cookie consent, and AddSearch for search functionality. Security headers are implemented, but TLS protocols are outdated and HSTS is not fully enabled, indicating room for improvement in transport security. Privacy and cookie policies are present and GDPR compliant, with consent mechanisms in place. Contact information is primarily via web forms, with no direct emails or phone numbers visible on the main page. Overall, the site demonstrates a mature digital presence with strong business focus but could enhance security posture and incident response transparency.

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.

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 operates as a major telecommunications and ICT service provider in Finland, serving business customers with a wide portfolio of products and services. Their business model integrates device sales, mobile and fixed subscriptions, IT and cloud services, security solutions, and consulting, enabling a one-stop-shop approach for enterprise ICT needs. The company leverages its strong brand and market position to offer bundled services such as Telia ONE and Telia Business Duetto. The website reflects a strategic focus on digital transformation, IoT, and AI technologies, targeting medium to large enterprises and public sector organizations. Partnerships with entities like inmicsnebula.fi and teliacygate.fi indicate an ecosystem approach to service delivery. The company’s content strategy includes customer stories, articles, webinars, and podcasts to engage and educate their audience, supporting customer retention and acquisition. The absence of direct contact emails suggests a controlled communication channel via web forms, likely for security and customer management reasons.

Security posture

The website exhibits a moderate security maturity level with several best practices in place, including strict transport security headers (HSTS header present but not fully enabled), X-Frame-Options, X-Content-Type-Options, and X-XSS-Protection. The SSL certificate is valid and issued by a trusted CA but the site does not support modern TLS protocols (TLS 1.2 or 1.3), which is a significant security gap. No vulnerabilities such as Heartbleed, POODLE, FREAK, or Logjam were detected. The site lacks a published security.txt file or explicit vulnerability disclosure policy, which limits transparency and incident response readiness. Contact channels for security incidents are not publicly visible. Cookie consent is implemented via OneTrust, indicating GDPR compliance and user privacy respect. Overall, while foundational security controls are present, the site should upgrade TLS support, enable full HSTS, and improve incident response visibility to enhance its security posture.

Recommendations

  1. Enable TLS 1.2 and TLS 1.3 protocols to ensure secure and modern encrypted communications.
  2. Fully enable HSTS with includeSubDomains and preload directives to protect against protocol downgrade attacks.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure and improve incident response.
  4. Provide clear and accessible contact information for security incidents, such as abuse@ or security@ email addresses.
  5. Establish CAA DNS records to restrict certificate issuance to authorized CAs and reduce risk of mis-issuance.
Technical notes

Notes

The website is built on Magnolia CMS and hosted on Sonera/Telia infrastructure, indicating a robust enterprise-grade platform. It uses modern JavaScript libraries such as jQuery and integrates advanced analytics and monitoring tools like Datadog RUM and Google Tag Manager. The site employs OneTrust for cookie consent management and AddSearch for search functionality, reflecting a mature digital marketing and compliance approach. Performance is fast with good mobile optimization and accessibility. SEO is well addressed with comprehensive metadata and Open Graph tags. However, the lack of support for modern TLS protocols and incomplete HSTS implementation represent technical debt and security risks. The site’s multi-level navigation and rich content structure demonstrate good technical architecture but could benefit from further modernization of security protocols and enhanced 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.
