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

Tender Service Schweiz operates as a leading European provider of public tender information and consulting services, targeting both large enterprises and SMEs. The company offers a comprehensive database of public tenders, combined with personalized consulting and advanced analytical tools to help clients win contracts efficiently. Their market position is strong, supported by over 20 years of experience and a broad service portfolio including market intelligence and tender forecasting. Technically, the website is built on modern Angular framework with PrimeNG components, supported by analytics tools such as Google Analytics and Microsoft Clarity, and hosted with good performance and mobile optimization. Security posture is solid with HTTPS enforced and appropriate security headers, though the absence of explicit privacy and terms of service pages slightly reduces compliance maturity. Overall, the website is professional, trustworthy, and well-structured, though improvements in transparency and contact information would enhance user trust and regulatory compliance.

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  3. 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

The company targets businesses interested in public procurement opportunities, providing tailored tender notifications and market insights. Their subscription-based model is complemented by expert consulting, positioning them as a trusted partner in the government sector. The website content and navigation reflect a mature digital presence with clear segmentation of services and industries. The absence of direct contact details on the website suggests a focus on registered users or controlled communication channels. The company is part of the Tender Service Group, indicating a broader organizational structure. Their marketing ecosystem includes tracking and user engagement tools, supporting customer acquisition and retention strategies.

Security posture

The website demonstrates a good security baseline with HTTPS and multiple security headers implemented. Forms are present with validation, reducing risk of injection or data leakage. However, no explicit security or incident response policies are published, and no vulnerability disclosure or security.txt files are found. Cookie consent is implemented, indicating awareness of privacy regulations. The lack of published privacy policy and terms of service pages is a compliance gap. No vulnerabilities or suspicious domains were detected in the analysis. Overall, the security posture is adequate for the business type but could be improved with formalized policies and transparency.

Recommendations

  1. Publish a comprehensive privacy policy page detailing data processing and GDPR compliance.
  2. Add a terms of service page to clarify user rights and obligations.
  3. Provide clear contact information including security incident response contacts.
  4. Implement and publish a vulnerability disclosure policy or security.txt file.
  5. Enhance transparency about data protection officer and certifications to build trust.

Technical notes

Notes

The website uses a modern Angular framework (version 20.3.2) with PrimeNG UI components, ensuring a responsive and interactive user experience. It leverages Storyblok as a headless CMS for content management. Analytics and user behavior tracking are implemented via Google Analytics, Microsoft Clarity, and Google Tag Manager, complemented by Userpilot for marketing automation. The site is well-optimized for mobile devices and performs well with fast loading times. Security headers and HTTPS are properly configured. There is no indication of legacy or vulnerable libraries. The technical infrastructure supports scalability and maintainability, though documentation of security and privacy policies would improve overall maturity.
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.
