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

The website karx.xyz is a personal portfolio site belonging to a computer science student at the University of Texas at Austin. It highlights the individual's skills in programming languages such as Rust, Python, Java, and C, as well as interests in Linux server administration and Docker. The site serves primarily as a showcase for personal projects and professional profiles, targeting technology enthusiasts, potential collaborators, and recruiters. The business model is personal branding and project demonstration, with no commercial transactions or services offered directly on the site. Technically, the site uses modern web technologies including ES modules and the flamethrower-router JavaScript framework to enable smooth page transitions. The hosting is inferred to be via Namecheap, consistent with the domain registrar information. The site is mobile optimized and has a clean, simple design with good navigation clarity. However, SEO and accessibility features are basic, and no CMS or analytics tools are detected. From a security perspective, the site uses HTTPS but lacks advanced security headers and policies such as Content-Security-Policy or X-Frame-Options. There are no privacy or cookie policies, and no incident response or vulnerability disclosure information is provided. The domain is privacy protected, which is reasonable for a personal site, and no suspicious WHOIS patterns are found. Overall, the security posture is moderate but could be improved with standard best practices. The overall risk assessment is low given the non-commercial nature and limited data collection. Strategic recommendations include implementing privacy and cookie policies, adding security headers, enabling DNSSEC, and providing vulnerability disclosure information to enhance 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

10 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. 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';…

  3. 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

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

Karx.xyz operates as a personal portfolio and project showcase for an individual in the technology sector, specifically a computer science student. The site positions itself as a personal brand rather than a commercial entity, targeting peers, recruiters, and open source collaborators. The business model is non-commercial, focusing on skill demonstration and networking. There are no revenue streams or partnerships indicated beyond friendly links to other personal sites. Growth indicators include active project development and public code repositories. The partnership ecosystem is limited to personal friends' websites. Overall, the site reflects a small-scale, individual operation with a focus on technology and software development.

Security posture

The security maturity level of karx.xyz is basic to moderate. HTTPS is enforced, which is mandatory, but the absence of security headers reduces the overall security posture. No sensitive data exposure or vulnerable libraries were detected. The site lacks formal privacy, cookie, and security policies, which are important for compliance and user trust. Incident response readiness and vulnerability disclosure mechanisms are not present, indicating limited security governance. The domain's privacy protection is justified given the personal nature of the site. There are no signs of malware or phishing. Overall, the security culture appears informal and could benefit from adopting standard security best practices.

Recommendations

  1. Enable DNSSEC to improve domain security and prevent DNS spoofing.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a privacy policy and cookie policy to improve compliance and user trust.
  4. Implement a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Consider adding basic analytics with privacy-respecting configurations to monitor site usage and improve user experience.

Technical notes

Notes

The website is built with modern web standards including HTML5, CSS, and JavaScript ES modules. It uses the flamethrower-router framework for client-side routing and page transitions, indicating a single-page application approach. The site is hosted on infrastructure associated with Namecheap, inferred from DNS servers. Performance is moderate with no heavy resources detected. Mobile optimization is good, but accessibility features are basic and could be enhanced. SEO is minimal with basic meta tags and Open Graph data present. There is no CMS detected, suggesting a static or custom-built site. The technical debt appears low, but modernization opportunities include adding accessibility improvements, SEO enhancements, and security hardening.
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.
