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

The website perseuslynx.dev is a personal portfolio and blog site for an individual named Perseus Lynx. It serves as a digital space to showcase projects, share blog posts, and provide personal information. The site targets a general audience interested in technology and personal projects. The business model is that of a personal brand with no commercial or enterprise scale operations. Technically, the site uses standard web technologies including HTML5, CSS3, and JavaScript, with modern image formats like WebP. Hosting appears to be via Cloudflare, with analytics provided by Umami and Cloudflare Insights. The site is moderately optimized for mobile and performance but lacks advanced SEO and accessibility features. Security posture is basic; HTTPS is presumed but no explicit security headers or policies are present. No privacy, cookie, or terms of service policies are found, indicating low privacy compliance. No contact information or incident response details are provided, limiting business credibility and user trust. Overall, the site is functional and professional for a personal portfolio but lacks formal security and compliance measures.

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

9 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

Perseus Lynx operates as an individual personal brand in the technology sector, focusing on project showcases and blogging. The site does not indicate any commercial transactions or partnerships. The business model is content and portfolio driven, targeting peers, potential collaborators, or employers. There is no evidence of revenue streams or formal business registrations. The lack of contact information and policies suggests a low level of formal business infrastructure. The site’s use of privacy protection in WHOIS is typical for personal domains and does not raise suspicion. The absence of trust indicators such as certifications or testimonials limits perceived credibility. The site’s ecosystem is minimal with no partner or subsidiary domains identified.

Security posture

Security maturity is basic. The site uses HTTPS and external analytics but lacks explicit security headers such as Content-Security-Policy or X-Frame-Options. No forms or inputs are present that collect sensitive data, reducing attack surface. No vulnerability disclosure or incident response information is provided, which is a gap for security readiness. The absence of privacy and cookie policies indicates non-compliance with GDPR and related regulations. No suspicious or malicious content detected. Overall, the security posture is adequate for a personal site but would benefit from formal policies and security headers to improve trust and compliance.

Recommendations

  1. Implement and publish privacy and cookie policies to improve compliance and user trust.
  2. Add explicit security headers (CSP, X-Frame-Options, etc.) to enhance security posture.
  3. Provide clear contact information and incident response channels for transparency.
  4. Consider adding a vulnerability disclosure policy or security.txt file.
  5. Improve accessibility and SEO features to enhance user experience and discoverability.

Technical notes

Notes

The website is built with standard web technologies including HTML5, CSS3, and JavaScript. It uses modern image formats (WebP) and external analytics services (Umami, Cloudflare Insights). Hosting is inferred to be via Cloudflare, providing CDN and security benefits. The site loads scripts deferred and uses local storage for theme preferences, indicating some client-side interactivity. Performance is moderate with no obvious errors or broken elements. Mobile optimization is good with viewport meta tags and responsive design. SEO is basic with meta description but no Open Graph or structured data found. Accessibility is basic with semantic HTML but no ARIA roles or landmarks detected. No CMS or frameworks detected, indicating a custom or static site build.
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.
