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

Yank Note is an open-source Markdown editor focused on extensibility, local data storage, and encryption for privacy-conscious users. It offers advanced Markdown features, plugin support, and AI integration to enhance the writing experience. The project is hosted on GitHub and provides multi-platform desktop applications for Windows, macOS, and Linux. The website is professionally designed with clear navigation and up-to-date content, reflecting a mature and active software project. Technically, the website leverages modern web technologies including React and Next.js, with Monaco Editor as the core editing engine. The site is fast, mobile-optimized, and accessible, with comprehensive download options and documentation links. However, there is room for improvement in security practices, such as enabling DNSSEC, implementing security headers, and publishing explicit privacy and cookie policies. From a security perspective, the project emphasizes local data storage and document encryption, reducing risks associated with cloud storage. The open-source nature enhances transparency, but the website lacks formal security policies and incident response contacts. Google Analytics is used for user tracking, but privacy compliance is minimal due to missing policies. Overall, Yank Note presents a trustworthy and technically sound offering in the Markdown editor market, with a strong focus on user privacy and extensibility. Strategic improvements in security disclosures and compliance documentation would enhance user trust and regulatory alignment.

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

9 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

  3. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Yank Note occupies a niche in the Markdown editor market by combining extensibility, encryption, and AI features. Its open-source business model supplemented by premium licenses targets developers, technical writers, and privacy-conscious users. The project demonstrates steady growth with active GitHub presence and user testimonials. Revenue streams include paid licenses for advanced features. The ecosystem includes documentation, plugin development guides, and API references, fostering community engagement. Partnerships appear limited to GitHub and related service providers. The business model balances free community access with monetization through premium offerings, positioning Yank Note as a specialized tool in the productivity software sector.

Security posture

The security posture of Yank Note is moderate. Strengths include local data storage, end-to-end document encryption, and open-source transparency. Weaknesses are the absence of DNSSEC, lack of security headers on the website, and missing formal security policies or vulnerability disclosure mechanisms. Incident response contacts are not publicly available, which may delay handling of security issues. The use of Google Analytics introduces moderate user tracking without clear privacy disclosures. Compliance with GDPR and other regulations is not explicitly addressed. Overall, the security maturity is adequate for a small open-source project but requires enhancements to meet enterprise-grade standards.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies to enhance compliance and user trust.
  3. Add security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options to harden the website against common attacks.
  4. Establish a vulnerability disclosure policy and publish a security.txt file to facilitate responsible reporting of security issues.
  5. Provide clear incident response contact information to improve security incident handling and transparency.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, with Monaco Editor powering the Markdown editing experience. It supports multi-platform desktop applications with clear versioning and download links hosted on GitHub. The site is well-structured, mobile-optimized, and fast-loading. However, the absence of DNSSEC and security headers indicates some technical debt in security hardening. The use of Google Analytics is standard but requires privacy policy alignment. Overall, the technical infrastructure is solid for a small to medium open-source project, with opportunities for security and compliance modernization.
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.
