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

Webmention.net serves as an informational hub for the Webmention protocol, a W3C Social Web Working Group specification contributed by the IndieWeb community. The site provides links to the latest published versions, drafts, and implementations of the protocol, targeting developers and web technologists interested in decentralized social web standards. The website is minimalistic, focusing on content delivery rather than commercial services or user engagement features. Technically, the site is hosted on Linode with domain registration through NameCheap, indicating a stable and reputable infrastructure. The technology stack is basic, consisting primarily of HTML and CSS, with no detected CMS or advanced frameworks. Performance and mobile optimization are moderate to basic, reflecting the simple nature of the site. From a security perspective, the site lacks advanced security headers, privacy policies, cookie consent mechanisms, and contact information for incident response. DNSSEC is not enabled, which is a recommended improvement for domain security. No analytics or tracking technologies are present, which reduces privacy concerns but also limits business intelligence capabilities. Overall, the website is safe and trustworthy for its intended audience but would benefit from enhanced security practices, privacy compliance documentation, and improved technical sophistication to better serve its community and maintain trust.

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 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';…

  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

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

Webmention.net operates as a niche technology standard platform within the web development and social web protocol space. It is community-driven, with no evident commercial business model or revenue streams. The target audience includes developers and members of the IndieWeb community interested in decentralized web communication protocols. The site’s market position is specialized and technical, focusing on protocol specification rather than product or service sales. The lack of business contact information and commercial indicators suggests a non-commercial or open-source community project. Growth indicators and partnerships are implied through links to W3C and IndieWeb but no formal partnerships or subsidiaries are identified.

Security posture

The current security posture of webmention.net is basic. The absence of DNSSEC, security headers, and incident response contact details indicates room for improvement in security maturity. The site uses HTTPS (implied by the URL), but no further SSL configuration details are available. No vulnerabilities or exposed sensitive data were detected in the content. The lack of privacy and cookie policies suggests compliance gaps with GDPR and other privacy regulations. Incident response readiness is minimal due to no published security contacts or vulnerability disclosure mechanisms. Overall, the site is low risk but would benefit from adopting standard security best practices and compliance documentation.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user transparency.
  3. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website against common attacks.
  4. Provide clear contact information for security incident response and consider publishing a security.txt file to facilitate vulnerability reporting.
  5. Consider improving technical infrastructure with modern frameworks and mobile optimization to enhance user experience and accessibility.

Technical notes

Notes

The website is built with basic HTML and CSS, with no detected JavaScript frameworks or CMS platforms. Hosting is provided by Linode, a reputable cloud hosting provider. The domain is registered with NameCheap and has a long registration period, indicating stability. Performance is moderate given the minimal content and simple design. Mobile optimization and accessibility are basic but functional. SEO optimization is minimal, with no meta tags or structured data detected. There is no evidence of analytics or tracking technologies, which limits data-driven insights but enhances privacy. The technical setup is sufficient for an informational site but could be modernized for better performance and user engagement.
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.
