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

烧饼博客 is a specialized Chinese technical blog focusing on Linux server administration, Docker, and domain investment analysis. The website provides detailed tutorials and guides targeting IT professionals and enthusiasts interested in server operations and domain management. It holds a niche position in the technology sector, catering primarily to a small audience of technical users. The business model appears to be content publishing with possible monetization through donations, as indicated by a donation link. The site is compliant with Chinese regulations, evidenced by the ICP备案 number, and maintains a consistent brand identity with a clear focus on technical content. Technically, the website is built on a modern Next.js framework, leveraging React and JavaScript for a fast and responsive user experience. The site is mobile-optimized and SEO-friendly, with structured data (JSON-LD) and Open Graph metadata implemented. Performance is good, and the site uses a custom CMS approach rather than a traditional CMS. However, no hosting provider details were detected. Analytics are minimal, using a custom tracking script from stat.u.sb. From a security perspective, the site enforces HTTPS with excellent SSL configuration but lacks important security headers such as Content-Security-Policy and X-Frame-Options. There is no published privacy policy, terms of service, or security policy, which are areas for improvement. The cookie consent banner is present, indicating some privacy compliance efforts. No vulnerabilities or exposed sensitive data were detected. WHOIS data is consistent with the website's origin and content, supporting legitimacy. Overall, the website is a well-maintained technical blog with good content quality and technical implementation but could improve its security posture and privacy compliance by adding relevant policies and security headers. The risk level is low, but enhancing transparency and security practices would strengthen trust and compliance.

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

4 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 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 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

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

烧饼博客 operates as a niche technical blog focused on Linux server administration and domain investment, targeting IT professionals and enthusiasts primarily in China. The business model centers on content publishing with tutorials and guides, supported by donations. The site maintains a consistent brand and regulatory compliance with an ICP备案 number. It leverages modern web technologies for performance and user experience. The lack of direct contact emails or phone numbers suggests a low-touch customer interaction model, relying on contact forms and social media (Mastodon) for engagement. The site does not appear to have partnerships or subsidiaries. Growth indicators include recent and frequent content updates. Strategic observations include the opportunity to expand privacy and security policies to enhance credibility and compliance.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a cookie consent mechanism in place. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended best practices to mitigate common web attacks. No incident response or vulnerability disclosure policies are published, limiting transparency in security management. No exposed sensitive data or vulnerable libraries were detected. The absence of privacy and terms of service policies indicates compliance gaps, particularly regarding GDPR and other privacy regulations. Incident response readiness and security culture indicators are minimal. Overall, the security posture is adequate for a small technical blog but requires enhancements to meet higher compliance and security standards.

Recommendations

  1. Implement comprehensive privacy policy and terms of service pages to improve legal compliance and user trust.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web vulnerabilities.
  3. Publish a security policy and vulnerability disclosure or security.txt file to improve transparency and incident response readiness.
  4. Enhance contact information availability by providing verified company emails or phone numbers to facilitate communication and trust.
  5. Regularly review and update security practices and privacy compliance to align with evolving regulations and best practices.

Technical notes

Notes

The website is built on a modern Next.js framework utilizing React and JavaScript, providing a fast and responsive user experience. It employs structured data (JSON-LD) and Open Graph metadata for SEO optimization. The site is mobile-optimized and has a clear navigation structure. Performance is good with minimal tracking scripts used. No CMS detected, indicating a custom-built solution. Hosting provider details are not disclosed. The site lacks some security headers, which is a technical debt area. Overall, the technical infrastructure is modern and well-implemented but could benefit from enhanced security configurations and documented policies.
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.
