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

张戈博客 is a personal technology blog focused on IT operations, scripting, and web technologies, primarily targeting IT professionals and enthusiasts in China. The site offers a rich collection of tutorials, technical articles, and resource sharing, positioning itself as a reputable source within the personal tech blogging community. The domain has been active since 2018 and is hosted on Tencent Cloud with CDN support, ensuring stable performance and moderate loading speeds. The website is built on WordPress and uses common web technologies such as PHP and jQuery, with additional references to modern frameworks like FastAPI in its content. Security-wise, the site employs HTTPS but lacks advanced security headers and explicit security or privacy policies, which could be improved to enhance trust and compliance. Analytics are handled via Baidu Analytics, with moderate user tracking but no visible cookie consent mechanisms. Overall, the site is well-designed, mobile-optimized, and provides good user experience, though it would benefit from enhanced privacy compliance and security best practices.

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. 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. 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

    • 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

The blog operates as a small-scale personal business focused on content creation and knowledge sharing in the IT operations and scripting domain. It leverages a content-driven business model without evident monetization through ads or affiliate programs. The target audience includes IT professionals, system administrators, and developers interested in Linux, scripting, and web technologies. The site maintains a consistent brand and has established trust indicators such as ICP备案 and social media presence. Its partnership ecosystem is limited to social media and CDN providers, with no evident commercial partnerships. Growth is organic, driven by content quality and community engagement through comments and social sharing.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, which is mandatory for secure communications. However, the absence of security headers like Content-Security-Policy, X-Frame-Options, and others reduces protection against common web attacks. No explicit privacy or cookie policies are present, indicating potential compliance gaps with GDPR or similar regulations. There is no published incident response or vulnerability disclosure policy, which limits transparency and preparedness. The site does not expose sensitive data or use known vulnerable libraries based on the provided content. Recommendations include implementing security headers, publishing privacy and security policies, and establishing incident response contacts to improve security maturity.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear consent mechanisms to improve compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Publish a security policy and incident response contact information to increase transparency and readiness.
  4. Regularly audit and update all plugins and scripts to mitigate vulnerabilities.
  5. Enhance accessibility features to meet broader compliance and user needs.

Technical notes

Notes

The website is built on WordPress, utilizing PHP and jQuery, with additional modern technologies referenced in blog content such as FastAPI. Hosting is provided by Tencent Cloud with CDN acceleration from multiple providers, ensuring moderate to good performance. The site is mobile-optimized and SEO-friendly with proper meta tags and structured navigation. However, there is room for improvement in accessibility and security configurations. The technical infrastructure is stable and suitable for a personal blog but could benefit from modernization in security practices and privacy compliance to reduce risks and improve user trust.
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.
