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

8 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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

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 site operates as a niche personal blog with a focus on AI and full-stack development, targeting developers and AI practitioners. Its business model includes content sharing, open source software promotion, and SaaS product marketing. The domain has been active since 2015, indicating a stable presence. The blog author appears to be an independent full-stack developer with a passion for creating tools and sharing knowledge. The site links to multiple GitHub repositories and SaaS offerings, suggesting an ecosystem of related projects. There is no explicit company or corporate entity disclosed, and no direct contact information is provided, which is typical for personal blogs.

Security posture

The website uses HTTPS, ensuring encrypted communication, but lacks DNSSEC which would enhance DNS security. No security headers such as Content-Security-Policy or X-Frame-Options were detected, representing an area for improvement. There are no forms or user input fields, reducing attack surface. Baidu Analytics is used without visible cookie consent or privacy policy, indicating potential compliance gaps with privacy regulations like GDPR. No incident response or security policy information is provided. Overall, the security posture is moderate but could be strengthened by implementing security headers, enabling DNSSEC, and adding privacy and cookie policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and security.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish clear privacy and cookie policies to enhance compliance with GDPR and other privacy regulations.
  4. Add visible contact information including a security or abuse email address for incident response.
  5. Regularly review and update third-party scripts and analytics tools to mitigate vulnerabilities.

Technical notes

Notes

The website is built on a modern static site generator (Hugo) with a clean and responsive design. It uses well-known JavaScript libraries for syntax highlighting and DOM manipulation. Hosting leverages cloud storage for media assets and possibly Vercel for deployment, indicating a modern infrastructure. Performance is likely fast due to static content delivery. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but present with skip links and viewport settings. No CMS or dynamic backend detected, reducing complexity and attack surface. Technical risks are low but could be improved by adding security headers and DNSSEC.
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.
