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

Boost.org hosts the Boost C++ Libraries, a well-established open source project providing peer-reviewed, portable, and free C++ libraries. The organization is community-driven and supported by grants from the C++ Alliance. The website reflects a mature project with a clear mission to advance software development best practices and inspire standard enhancements. The target audience is primarily C++ developers and software engineers seeking high-quality libraries to improve productivity and reduce maintenance costs. Technically, the site uses modern JavaScript frameworks such as Alpine.js and htmx, with a clean, responsive design optimized for desktop and mobile. Analytics are handled via privacy-focused plausible.io, indicating a minimal user tracking approach. Security posture is good with HTTPS enforced, but lacks some advanced security headers and published security policies. WHOIS data is unavailable due to privacy protection, which is typical for open source projects. Overall, the site is professional, trustworthy, and well-maintained.

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

5 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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 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

Boost holds a strong market position as a leading provider of C++ libraries with over 10 million downloads and 165+ individual libraries. Its open source business model relies on community contributions and grants, notably from the C++ Alliance. The project benefits from a broad ecosystem of contributors and maintainers, with active release schedules and community engagement. The absence of direct contact emails or phone numbers suggests a preference for community mailing lists and online collaboration. Social media presence across multiple platforms supports outreach and developer engagement. The project’s transparency and peer-reviewed approach provide competitive advantages in reliability and adoption. Growth indicators include frequent releases and active news updates. Strategic partnerships with the C++ Alliance enhance credibility and resource support.

Security posture

The website demonstrates a solid baseline security posture with HTTPS enabled and no visible exposure of sensitive data. However, it lacks several recommended security headers such as Content-Security-Policy and X-Frame-Options, which could improve protection against common web attacks. There is no publicly available security policy or incident response information, which limits transparency for security researchers and users. No vulnerability disclosure or security.txt files were found, reducing clarity on how to report security issues. The minimal use of tracking and absence of advertising networks reduce privacy risks. Overall, the security maturity is moderate but could be enhanced by adopting best practices in security headers, publishing policies, and formal vulnerability disclosure mechanisms.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance web security.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Introduce a cookie consent mechanism to comply with privacy regulations and improve user trust.
  5. Enhance accessibility features to improve usability for all users and meet compliance standards.

Technical notes

Notes

The website is built with modern front-end technologies including Alpine.js for reactive components, htmx for dynamic content loading, and ApexCharts for data visualization. It uses Google Fonts and FontAwesome for typography and icons, ensuring a visually appealing and consistent design. The site is responsive and optimized for mobile devices, with a clear navigation structure. Performance is moderate, with external dependencies on CDNs for scripts and fonts. No CMS was detected, indicating a custom or static site architecture. Hosting provider details are not disclosed. The site could benefit from improved SEO metadata and enhanced accessibility compliance. Overall, the technical infrastructure supports a professional and user-friendly experience with room for modernization in security and privacy features.
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.
