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

Sylvie.lol is a personal portfolio and blog website belonging to Sylvia (aka sylvxa), a full-stack software developer and programming enthusiast. The site serves as a platform to share programming knowledge, open source projects, and personal interests such as speedrunning and cats. It targets a niche audience of developers and tech hobbyists. The website is newly created in 2024 and reflects a small-scale personal brand rather than a corporate entity. Technically, the website uses standard modern web technologies including HTML5, CSS3, and JavaScript, with Cloudflare providing DNS and likely CDN services. The site is well-structured with good mobile optimization and SEO meta tags. However, it lacks advanced frameworks or CMS platforms, indicating a lightweight and custom-built approach. From a security perspective, the site benefits from HTTPS and domain transfer protection but lacks DNSSEC and security headers such as Content-Security-Policy. There are no visible forms or data collection mechanisms, reducing attack surface but also limiting user interaction. Privacy and cookie policies are absent, which is a compliance gap. No incident response or vulnerability disclosure information is provided. Overall, sylvie.lol is a safe, well-maintained personal website with moderate trustworthiness. To improve, the owner should consider adding privacy and cookie policies, security headers, and contact information to enhance compliance and user trust.

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 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';…
  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

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 website represents an individual software developer's personal brand rather than a commercial business. Its market positioning is niche and personal, focusing on software development, blogging, and open source contributions. Revenue streams or monetization are not evident. The target audience includes fellow developers and programming enthusiasts. The site leverages partnerships indirectly through external platforms like Discord, GitHub, and Modrinth. Growth indicators are limited due to the site's recent creation and personal nature. There is no evidence of formal partnerships or subsidiaries.

Security posture

The security posture is basic but adequate for a personal portfolio site. HTTPS is enforced, and domain transfer protection is enabled. However, the absence of DNSSEC and security headers reduces defense-in-depth. No forms or user input fields minimize exposure to injection or data leakage risks. The lack of privacy and cookie policies indicates non-compliance with GDPR and related regulations. Incident response readiness and vulnerability disclosure mechanisms are not present, which could delay mitigation of potential issues. Overall, the site is low risk but could benefit from standard security best practices.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  3. Add a privacy policy and cookie policy pages to comply with GDPR and improve user trust.
  4. Provide clear contact information and a security incident response policy to enhance transparency and readiness.
  5. Consider integrating basic analytics with privacy-respecting configurations to understand visitor behavior without compromising privacy.

Technical notes

Notes

The website is built with clean, valid HTML and CSS, and uses JavaScript for minor dynamic content (time display). It employs custom fonts loaded via @font-face. Hosting appears to be via Cloudflare DNS and CDN services, ensuring fast performance and global availability. The site is mobile optimized with responsive meta tags and CSS. No CMS or heavy frameworks are detected, indicating a lightweight custom build. No analytics or advertising scripts are present, minimizing tracking. The site could improve accessibility features and add ARIA roles or landmarks for better compliance.
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.
