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

nuun - webs & apps GmbH is a Swiss-based digital agency specializing in custom web design, app development, and online shops, primarily serving clients in the Thurgau region, specifically Weinfelden. The company positions itself as a local expert offering tailored digital solutions including corporate branding and web hosting. The website content is professionally presented in German, targeting small and medium-sized businesses seeking bespoke digital services. The agency maintains an active presence on social media platforms such as Facebook, Instagram, and LinkedIn, and offers newsletter subscriptions to engage its audience. Technically, the website is built on the Contao Open Source CMS and leverages modern web technologies including jQuery and Slick Carousel for interactive content. It integrates Google Tag Manager and Matomo for analytics, indicating a moderate level of digital maturity and user tracking. The site is mobile-optimized with good SEO practices, although accessibility features could be enhanced. Performance is moderate, with no critical technical debt observed. From a security perspective, the website enforces HTTPS and includes several important security headers such as Content-Security-Policy and Strict-Transport-Security. Forms are protected with CSRF tokens, and no exposed sensitive data or vulnerable libraries were detected. However, the absence of a cookie consent mechanism and explicit security or incident response policies represents areas for improvement. Privacy compliance is generally good, with a clear privacy policy in place and GDPR compliance indicators, but cookie consent and terms of service pages are missing. Overall, nuun.ch presents a trustworthy and professional digital presence with a solid security posture and business credibility. Strategic recommendations include implementing a cookie consent banner, publishing terms of service and security policies, and enhancing accessibility. These steps will improve compliance, user trust, and security culture, supporting the agency's growth and reputation in the competitive Swiss digital market.

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

6 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 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';…

  3. 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

    • 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

  4. 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 · found on this site
  • 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.

Business context

Business profile

nuun - webs & apps GmbH operates as a specialized web agency focused on delivering custom digital solutions to local businesses in Switzerland. Its competitive advantage lies in personalized service and regional expertise in Thurgau. The business model centers on service provision including web design, app development, online shops, and branding, targeting SMEs. Revenue streams likely derive from project-based contracts and ongoing hosting or maintenance services. The company leverages social media and newsletters for client engagement and marketing. Growth indicators include a professional website with integrated analytics and active social media links. The partnership ecosystem includes analytics providers and newsletter services, but no explicit business partners or subsidiaries were identified. Strategic observations suggest the company is well-positioned locally but could benefit from enhanced compliance and security transparency to strengthen market trust.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented, reducing risks of common web attacks. The use of CSRF tokens in forms and absence of exposed sensitive data indicate good security hygiene. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure mechanisms limits transparency and preparedness. Privacy compliance is partial, with a privacy policy present but missing cookie consent and terms of service. No vulnerabilities or malware were detected in the provided content. The security score is high but could be improved by addressing compliance gaps and publishing incident response information. Overall, the security culture appears professional but could be enhanced with formalized policies and user-facing disclosures.

Recommendations

  1. Implement a cookie consent banner to ensure compliance with EU cookie laws and enhance user privacy transparency.
  2. Publish a comprehensive terms of service page to clarify user rights and obligations.
  3. Develop and publish a security policy and incident response contact information to improve transparency and readiness.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance website accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on the Contao Open Source CMS platform, utilizing jQuery and Slick Carousel for interactive UI components. It integrates Google Tag Manager and Matomo for analytics, reflecting a moderate level of technical sophistication. The site is mobile-optimized and includes proper meta tags for SEO. Performance is moderate with no critical technical issues detected. Security headers and HTTPS are properly configured. Technical debt appears low, but opportunities exist to modernize accessibility and implement cookie consent mechanisms. Hosting provider details were not explicitly detected. Overall, the technical infrastructure supports the business needs effectively with room for incremental improvements.
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.
