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

The website vieron.net serves as a personal professional portfolio for Javi Sánchez-Marín, an interdisciplinary software engineer with over 15 years of experience specializing in frontend infrastructure and tooling. The site highlights his current role at Stripe and showcases his expertise in software engineering and design. The business model is personal branding and professional presence rather than a commercial enterprise. The website is built using modern technologies such as Astro and hosted on Vercel, indicating a contemporary and performant technical infrastructure. The site loads quickly, is mobile optimized, and uses Google Fonts for typography. Security posture is moderate; HTTPS is implied but no explicit security headers or policies are present. There are no privacy or cookie policies, and no contact information is provided, which limits compliance and user trust. No WAF or blocking mechanisms are detected, and the domain WHOIS data is consistent and transparent, supporting legitimacy. Overall, the site is professional and well-structured but lacks important compliance and security documentation.

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

7 findings rated critical or high. Fix these first.

  1. 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"

    • 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';…

  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 individual behind the website positions himself as a seasoned software engineer with a strong design background, targeting technology professionals and potential employers or collaborators. The site does not operate as a commercial business but as a personal portfolio. The domain age of over 15 years aligns with the professional experience claimed. The site links externally to Stripe, indicating current employment, and uses Vercel for hosting. There is no evidence of revenue streams, partnerships, or subsidiaries. The site’s simplicity and focus on personal branding suggest a low operational complexity but a clear market positioning as a technology professional.

Security posture

The website’s security posture is basic. While HTTPS is presumably enabled (common with Vercel hosting), no security headers such as Content-Security-Policy or Strict-Transport-Security are detected. There are no visible vulnerabilities or exposed sensitive data. However, the absence of privacy and cookie policies, as well as incident response contacts, indicates gaps in compliance and security readiness. The use of Vercel Analytics introduces minimal user tracking without clear privacy disclosures. Overall, the site is low risk but would benefit from enhanced security headers and compliance documentation to improve trust and resilience.

Recommendations

  1. Implement comprehensive privacy and cookie policies with GDPR compliance considerations.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information including a security incident response contact or abuse email.
  4. Enable DNSSEC for the domain to strengthen DNS security.
  5. Regularly audit and update third-party scripts and analytics tools to ensure no vulnerabilities.

Technical notes

Notes

The website is built using Astro v3.0.12, a modern static site generator, and hosted on Vercel, which provides fast and reliable performance. Google Fonts are used for typography, and Vercel Analytics is implemented for minimal user tracking. The site is mobile optimized and loads quickly. No CMS is detected, indicating a static site architecture. There is no evidence of technical debt or outdated technologies. However, the lack of security headers and compliance documentation represents a technical risk. The site’s SEO and accessibility are basic but adequate for a personal portfolio. Overall, the technical implementation is modern and efficient but could be improved with enhanced security and compliance features.
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.
