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

Blowfish is an open source, lightweight theme designed for the Hugo static site generator. It targets developers and users seeking a powerful yet simple theme solution for their Hugo-based websites. The website serves as a demo, documentation hub, and community showcase for the theme, supported by social media presence on Twitter and GitHub. The business model revolves around open source distribution with community engagement and merchandising. Technically, the site is built with Hugo 0.142.0, uses modern JavaScript libraries such as jQuery and medium-zoom, and is optimized for mobile and accessibility. Performance is fast with good SEO practices. Security posture is moderate; HTTPS is used, but explicit security headers are missing and no privacy or cookie policies are present. No forms collect sensitive data, reducing risk exposure. The domain uses privacy protection in WHOIS, which is typical for small open source projects. Overall, the site is professional and trustworthy but lacks formal privacy and security documentation.

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

6 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 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Blowfish occupies a niche market as a Hugo theme provider, leveraging open source principles and community contributions. Its competitive advantage lies in its lightweight design and comprehensive documentation. Revenue streams likely include merchandising and possibly donations via Buy Me a Coffee. The target audience is developers and Hugo users seeking quality themes. The partnership ecosystem includes GitHub and social media platforms for distribution and engagement. Growth indicators include active documentation updates and user showcases. Strategic observations suggest focusing on enhancing privacy compliance and security transparency to build greater trust.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and no sensitive data is exposed in the HTML. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. There is no visible privacy policy or cookie consent mechanism, indicating compliance gaps with GDPR and related regulations. Incident response contact channels are not provided, limiting readiness for security events. No vulnerability disclosure policy or security.txt is present. The use of third-party scripts like Google Tag Manager and Buy Me a Coffee introduces potential tracking and privacy considerations. Overall, the security culture appears informal, typical for small open source projects, but improvements are recommended.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance.
  2. Add explicit security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information for security incidents and consider a vulnerability disclosure policy.
  4. Audit third-party scripts regularly to ensure no vulnerable libraries are included.
  5. Enhance transparency around data collection and user tracking to improve privacy compliance.

Technical notes

Notes

The website is built on the Hugo static site generator version 0.142.0, leveraging modern JavaScript libraries such as jQuery and medium-zoom for enhanced user experience. It uses lite-youtube-embed for optimized video embedding. The site is well-structured with valid HTML and CSS, optimized for mobile devices and accessibility. Performance is fast due to static site architecture. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data. No CMS beyond Hugo is detected. Hosting provider details are not explicit. Technical risks include lack of security headers and absence of privacy compliance mechanisms, which could impact user trust and regulatory adherence.
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.
