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

Kern On is a specialized software tool designed to assist type designers and font producers with kerning tasks, implemented as a plug-in for Glyphs. The business is operated by Just Another Foundry GmbH, a small German company founded in 2018, with clear business identity and contact information. The website provides product demos, purchase options, and user support via a forum, targeting a niche market in typography software. Technically, the site uses standard web technologies (HTML5, CSS3, JavaScript) and is hosted with domain services from DomainControl. The site is mobile-optimized and offers a good user experience with clear navigation and relevant content. Security posture is moderate; domain registration protections are in place, but DNSSEC is not enabled and security headers are missing. Privacy compliance is partial, with a privacy policy linked externally but no cookie consent mechanism despite use of Matomo analytics. Overall, the site is trustworthy and professional but could improve security and privacy practices.

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. 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

      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';…

  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

    • 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

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 operates in a niche technology sector focused on typography and font design tools. Its competitive advantage lies in specialized kerning assistance software integrated with popular font design platforms. Revenue is likely generated through software sales and updates. The target customers are professional type designers and font producers. The company maintains a small but consistent online presence with related domains and social media. Growth potential depends on expanding user base and maintaining product relevance. Partnerships with related font tool providers enhance ecosystem strength. The business model is straightforward, focusing on product quality and user support.

Security posture

The website demonstrates a moderate security maturity level. Domain registration includes standard protection statuses preventing unauthorized transfers or deletions. However, the absence of DNSSEC and security headers reduces resilience against DNS attacks and common web vulnerabilities. No incident response or security policy is published, limiting transparency and preparedness. The use of Matomo analytics suggests privacy-conscious tracking, but lack of cookie consent is a compliance gap. No critical vulnerabilities or exposed sensitive data were detected. Overall, security practices are adequate for a small business but should be enhanced to meet higher compliance standards.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website.
  3. Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
  4. Publish a formal security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.

Technical notes

Notes

The website is built with standard web technologies and shows good mobile responsiveness and user experience. Hosting is managed via DomainControl DNS services. Performance is moderate with no major issues detected. The site lacks advanced frameworks or CMS, indicating a lightweight and custom-built approach. SEO and accessibility are basic but functional. The presence of Matomo analytics indicates a preference for privacy-friendly tracking. Technical debt appears low, but modernization opportunities include adding security headers and improving privacy compliance. No critical technical risks were identified that would impact business operations.
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.
