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

The website 'Chez DeuZa (aka 0x2a)' is a personal blog primarily targeting tech enthusiasts, geeks, and hobbyists interested in AI, open source projects, cats, and DIY topics. It is hosted on the Tumblr platform and features a variety of posts including technical guides, personal opinions, and project links. The site demonstrates moderate digital maturity with basic mobile optimization and standard SEO practices. However, it lacks formal privacy, cookie, and terms of service policies, which impacts compliance and user trust. Security posture is minimal with no detected security headers or incident response information. The WHOIS data is incomplete, raising concerns about domain legitimacy. Overall, the site serves as a niche personal blog with good content quality but requires improvements in security and compliance to enhance trustworthiness.

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

3 findings rated critical or high. Fix these first.

  1. 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

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 platform without commercial business operations or revenue streams evident. It leverages open source and community-driven content, linking to projects on GitHub and other platforms. The target audience includes French-speaking tech-savvy individuals and cat lovers. The site does not present formal business information or certifications, indicating a hobbyist or individual operator rather than a corporate entity. Partnerships appear limited to community and open source projects. Growth indicators and market positioning are modest, focused on content sharing rather than monetization.

Security posture

Security maturity is low with no visible security headers such as CSP, HSTS, or X-Frame-Options. The site uses HTTPS (assumed from Tumblr hosting) but lacks explicit privacy and cookie policies, reducing GDPR compliance. No incident response or vulnerability disclosure information is provided. Tracking pixels from Tumblr analytics and Comscore indicate moderate user tracking without clear privacy controls. The absence of registrant data in WHOIS and lack of security best practices suggest potential risks. The site would benefit from implementing security headers, formal privacy documentation, and incident response contacts to improve security posture.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers such as Content Security Policy, HSTS, and X-Frame-Options to enhance protection.
  3. Publish incident response and vulnerability disclosure information to build trust and readiness.
  4. Improve mobile optimization and accessibility to enhance user experience across devices.
  5. Verify domain registration details and ensure WHOIS information is complete and accurate.

Technical notes

Notes

The website is built on the Tumblr platform, utilizing standard HTML, CSS, and JavaScript. It includes embedded videos, images, and links to external resources. The site uses Tumblr's analytics and tracking pixels, with no custom hosting or advanced frameworks detected. Performance is moderate with basic mobile responsiveness. The technical stack is simple and typical for a personal blog, with opportunities to modernize SEO and accessibility features. No CMS other than Tumblr is detected, and hosting provider details are not explicit but presumed to be Tumblr's infrastructure.
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.
