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

vibed.org is the official website for vibe.d, an open source asynchronous I/O and web toolkit framework written in the D programming language. The project targets developers seeking efficient, fiber-based blocking programming models and high-performance web frameworks. The site provides detailed feature descriptions, code examples, documentation, and community resources, positioning itself as a niche but mature technology framework with a consistent update cadence since its founding in 2012. Technically, the website employs standard web technologies including Bootstrap CSS and Normalize.css for styling, and Prettify.js for code syntax highlighting. Hosting is managed through German-based hosting providers, with stable DNS configurations. The site is mobile optimized and well structured, offering a good user experience and clear navigation. However, it lacks advanced accessibility features and modern security headers. From a security perspective, the site uses a domain status that prevents unauthorized transfers but does not enable DNSSEC. No HTTPS or SSL configuration details were provided, and no security headers were detected in the HTML content. Privacy compliance is minimal, with no cookie consent mechanisms or GDPR-specific disclosures. Contact information is limited to a contact page form, with no direct emails or phone numbers published. No vulnerability disclosure or incident response policies are present. Overall, vibed.org is a credible and professional technical project website with good content quality and business credibility. Security posture and privacy compliance require improvement to meet modern standards. The site is safe for general audiences and free from suspicious or malicious content.

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

vibe.d operates as an open source software project focused on asynchronous I/O and web frameworks for the D programming language. Its market positioning is niche, targeting developers who require high-performance, fiber-based concurrency models. The business model revolves around community engagement, open source contributions, and dissemination of knowledge through documentation and a published book. Revenue streams are not explicit but may include book sales and potential sponsorships. The ecosystem includes GitHub for code hosting and community interaction, with no evident commercial partnerships or subsidiaries. Growth indicators include regular software releases and active community forums. Strategic observations suggest focusing on enhancing privacy compliance and security policies to increase trust and adoption.

Security posture

The current security maturity level of vibed.org is moderate. The domain is registered with a reputable registrar and has a long history consistent with the project age. However, the absence of DNSSEC, security headers, and explicit HTTPS/SSL details indicates room for improvement. No exposed sensitive data or vulnerabilities were detected in the content. The lack of a published security policy or incident response contacts limits transparency and readiness. Compliance gaps exist regarding GDPR and cookie consent mechanisms. The security culture appears informal, typical for open source projects, but could benefit from formalized policies and disclosures to enhance trustworthiness.

Recommendations

  1. Enable DNSSEC and implement comprehensive security headers (CSP, HSTS, X-Frame-Options) to strengthen domain and site security.
  2. Publish explicit privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  3. Develop and publicize a vulnerability disclosure policy and security incident response contacts to enhance transparency and readiness.
  4. Add direct contact information such as verified company emails and phone numbers to improve business credibility and user trust.
  5. Regularly audit and update technical infrastructure to maintain performance, accessibility, and security best practices.

Technical notes

Notes

The website uses a clean and modern tech stack centered around the D programming language framework vibe.d, with Bootstrap and Normalize.css for styling and Prettify.js for code highlighting. Hosting is stable with German-based providers. The site is mobile responsive and well structured, offering good performance and SEO optimization. However, accessibility features are basic and could be improved. No CMS is detected, indicating a custom or static site approach. The absence of analytics or tracking scripts suggests minimal data collection, aligning with privacy-conscious design. Technical risks include missing security headers and lack of DNSSEC, which could expose the site to certain attack vectors.
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.
