H2G Internetagentur AG is a Swiss-based web agency located in Aarau, specializing in consulting, design, development, and hosting of websites and web applications. The company targets businesses and institutions seeking innovative and user-centric digital solutions. Their market position is that of a reputable regional agency with a diverse client base, including international companies and local institutions. The website reflects a professional and modern digital presence with clear service offerings and client references. Technically, the website employs modern web technologies including JavaScript, SVG graphics, and Matomo for privacy-conscious analytics. The site is well-optimized for mobile devices and demonstrates good SEO and accessibility practices. Hosting appears to be managed internally or via trusted providers, with HTTPS enforced and minimal tracking. From a security perspective, the site uses HTTPS and respects user privacy by disabling cookies in analytics and honoring Do Not Track signals.

The risk profile is low, with recommendations to enhance security headers and add explicit cookie consent mechanisms to further improve privacy compliance and security posture.

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

10 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
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

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

      • NIS2 21(2)(e)

      • 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 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"

    • High

      Missing Content-Security-Policy header

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.

Technical appendix

Business context

Business profile

H2G Internetagentur AG operates as a specialized technology service provider focusing on web development and digital transformation services. Their competitive advantage lies in combining user-centered design with robust technical implementation and hosting capabilities. The business model is service-oriented, targeting SMEs, institutions, and international clients. The company demonstrates strong local ties and a broad partnership ecosystem, as evidenced by numerous client references. Growth indicators include a well-maintained website and active social media presence. Strategic observations suggest a focus on quality and innovation, positioning them well in the Swiss digital agency market.

Security posture

The security maturity of H2G Internetagentur AG's website is moderate to high. The use of HTTPS and privacy-respecting analytics indicates a good baseline. The absence of common security headers such as Content-Security-Policy and X-Frame-Options is a minor gap. No exposed sensitive data or vulnerable libraries were detected. The site lacks published incident response or security policies, which could improve transparency and readiness. Compliance with GDPR is evident through the privacy policy and cookie management practices, although a formal cookie consent mechanism is missing. Overall, the security culture appears positive but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Add a clear cookie consent banner/mechanism to comply fully with GDPR and ePrivacy Directive requirements.
  3. Publish explicit security and incident response policies to improve transparency and preparedness.
  4. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.
  5. Enhance trust signals by adding certifications or security badges where applicable.

Technical notes

Notes

The website is built with modern web standards including HTML5, CSS3, and JavaScript. It uses SVG for scalable graphics and Matomo for analytics, indicating a preference for privacy-friendly tools. The site is mobile-optimized and loads efficiently, suggesting good performance practices. No CMS was explicitly detected, implying a custom or static site architecture. Hosting appears stable with HTTPS enforced. Technical risks are minimal, but the absence of some security headers and cookie consent mechanisms represent areas for improvement. The site structure and metadata are well-formed, supporting SEO and accessibility.
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.
