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

Telge is a comprehensive municipal service provider focused on delivering essential services to the city of Södertälje, Sweden. Their offerings span housing, electricity networks, district heating and energy, fiber networks, water and sewage, and recycling services. The website targets both private individuals and businesses within the local community, positioning Telge as a key local player in public utilities and municipal services. The company also maintains partnerships with related entities such as Södertälje Hamn and Tom Tits Experiment, indicating a diversified municipal group structure. Technically, the website leverages modern web technologies including Blazor WebAssembly, Microsoft Application Insights for telemetry, and Google Maps API for location services. The site is hosted on Azure infrastructure, ensuring reliable performance and scalability. The site is mobile-optimized, accessible, and SEO-friendly, with a clear navigation structure and professional design. From a security perspective, the site enforces HTTPS, uses nonce-based script loading, and integrates monitoring via Application Insights. However, it lacks explicit public-facing security policies, incident response contacts, and vulnerability disclosure mechanisms, which are recommended for enhanced transparency and trust. Privacy compliance is strong with clear GDPR-aligned privacy and cookie policies, including a consent mechanism. Overall, Telge's website reflects a mature digital presence consistent with a large municipal service provider. The security posture is solid but could be improved with additional transparency around incident response and vulnerability disclosures. The site is trustworthy, well-branded, and provides comprehensive service information to its audience.

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

7 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

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

Telge operates as a municipal service provider with a broad portfolio covering housing, energy, utilities, and recycling. Their business model is centered on serving the local community of Södertälje, Sweden, with essential public services. The company benefits from a strong local market position as a trusted provider and employer. Revenue streams likely include rents, utility fees, and service charges. The website indicates a focus on both private customers and businesses, with dedicated sections for each. Partnerships with entities like Södertälje Hamn and Tom Tits Experiment suggest a strategic ecosystem of municipal subsidiaries and related companies. Growth indicators include active job postings and ongoing service updates. The company maintains a professional online presence with clear branding and social media engagement, supporting community outreach and transparency.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, use of nonce attributes in scripts to mitigate XSS risks, and integration of Microsoft Application Insights for monitoring and telemetry. The presence of a service worker indicates modern progressive web app features. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure page limits transparency and may hinder rapid incident reporting or response. GDPR compliance is evident through privacy and cookie policies with consent mechanisms. Overall, the security posture is solid for a municipal website but could be enhanced by publishing explicit security governance documents and contact channels for security incidents.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Create and publicize an incident response contact email or page to facilitate reporting.
  3. Implement and publish a vulnerability disclosure or security.txt file to encourage responsible disclosure.
  4. Add a terms of service page to clarify user rights and obligations.
  5. Continue monitoring and updating third-party libraries to avoid vulnerabilities.

Technical notes

Notes

The website is built using modern web technologies including Blazor WebAssembly, which allows for rich client-side interactivity using .NET. It uses IndexedDB for client-side storage and registers a service worker for offline capabilities. The site integrates Microsoft Application Insights for telemetry and error tracking, and Google Maps API for geolocation services. Hosting appears to be on Microsoft Azure, inferred from telemetry endpoints. The site is well-structured with responsive design, good accessibility features, and SEO-optimized metadata. Performance is moderate, with deferred script loading and lazy loading of images. Technical risks are minimal but include the need to maintain up-to-date dependencies and improve transparency around security practices.
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.
