36/100

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

The website roehler.ch serves as a personal and professional wiki and documentation platform managed by Sven Röhler, focusing on IT solutions and services primarily for small and medium enterprises (KMU) and private users in Switzerland. The site provides extensive technical content, guides, and links related to Linux, Windows, programming, and IT infrastructure. The market position is niche and local, with a focus on knowledge sharing and IT consultancy. Technically, the site is built on CMSimple 5.12 with standard web technologies including HTML5, CSS3, JavaScript, and jQuery. The site is moderately optimized for performance and mobile use but lacks advanced SEO and accessibility features. Security posture is basic, with no HTTPS enforcement or security headers detected, and no published privacy or cookie policies, which are critical gaps. No contact information or incident response channels are provided, limiting user trust and compliance. Overall, the site is functional and content-rich but requires significant improvements in security, privacy compliance, and professional contact transparency to enhance trust and compliance.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

3 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Roehler.ch operates as a small-scale IT service and knowledge platform, targeting SMEs and private clients in Switzerland. The business model revolves around providing IT consultancy, solutions, and a comprehensive wiki for IT professionals and enthusiasts. The site’s extensive content on Linux distributions, programming, and system administration indicates a strong technical expertise focus. There is no evidence of monetization through advertising or affiliate programs, suggesting a service-oriented or personal brand approach. The related domain röhler.ch is positioned as the official business website, indicating a dual-domain strategy. The absence of formal business contact details and certifications limits the perceived credibility and growth potential. The partnership ecosystem includes a Nextcloud service domain, indicating cloud service integration. Strategic observations suggest opportunities to formalize business presence with clearer contact channels and compliance documentation.

Security posture

The current security posture of roehler.ch is minimal. The site lacks HTTPS enforcement, security headers, and published security or privacy policies. No incident response or vulnerability disclosure mechanisms are evident. The absence of cookie consent and privacy policies indicates non-compliance with GDPR and related regulations. No analytics or tracking scripts are detected, which reduces privacy risks but also limits user behavior insights. The site’s use of CMSimple and jQuery is standard but requires regular updates to mitigate vulnerabilities. Overall, the security maturity is low, exposing the site to potential risks such as data interception, lack of user data protection, and reduced trustworthiness. Immediate improvements should focus on implementing HTTPS, security headers, privacy documentation, and contact channels for security incidents.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections site-wide.
  2. Add comprehensive privacy and cookie policies with GDPR compliance and a consent mechanism.
  3. Publish clear contact information including emails and phone numbers for business and security incidents.
  4. Configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Enhance mobile optimization and accessibility to improve user experience and SEO.

Technical notes

Notes

The website is built using CMSimple 5.12, a lightweight PHP-based CMS, combined with jQuery 3.5.1 and jQuery UI 1.10.4 for client-side interactivity. The HTML structure is valid but basic, with multiple CSS stylesheets for layout and theming. The site uses standard meta tags for SEO but lacks Open Graph or JSON-LD structured data. Performance is moderate with no evident advanced optimization techniques. The navigation is extensive but many menu items are hidden by default, which may affect usability. No modern JavaScript frameworks or analytics tools are used, indicating a simple technical infrastructure. Hosting provider details are not disclosed. The site would benefit from modernization, including responsive design improvements, SEO enhancements, and security hardening.
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.
