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

The website mareksivco.sk represents the personal and professional portfolio of Mgr. Marek Sivčo, a Slovak teacher, web developer, poet, and podcaster. The site highlights his extensive experience in web development, teaching engagements, creative works, and supported projects. It targets individuals interested in IT education, Slovak geek culture, and creative arts. The business model is centered on personal branding and educational content delivery, with a niche market position in Slovakia and the broader Slovak-speaking community. Technically, the website employs a modern tech stack including PHP, WordPress, JavaScript, and various Adobe creative tools. Hosting is provided by Websupport, with DNSSEC enabled and HTTPS properly configured, indicating a secure and reliable infrastructure. The site is mobile-optimized and SEO-friendly, though accessibility features are basic. No analytics or tracking scripts are present, reflecting a privacy-conscious approach. From a security perspective, the site benefits from HTTPS and DNSSEC but lacks security headers and formal security policies. No vulnerability disclosure or incident response information is provided, and no privacy or cookie policies are found, which are notable compliance gaps. The absence of forms reduces attack surface but also limits user interaction. Overall, the website is professional, trustworthy, and content-rich, with strong business credibility but room for improvement in privacy compliance and security best practices. Strategic recommendations include adding privacy and cookie policies, implementing security headers, and publishing a vulnerability disclosure policy 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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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';…

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

Marek Sivčo operates as a small personal brand focused on IT education, web development, and creative content production. His market positioning leverages his 20 years of experience and multiple client references, including notable Slovak companies and projects. The business model is service and content-based, with revenue likely from teaching, freelancing, and podcasting. The target audience includes IT learners, Slovak geeks, and creative arts enthusiasts. Partnerships with educational platforms and media outlets strengthen his ecosystem. Growth indicators include ongoing teaching roles and active project development. The website serves as a central hub for his professional and creative activities.

Security posture

The website demonstrates a moderate security maturity level with HTTPS and DNSSEC enabled, ensuring encrypted communication and domain integrity. However, the lack of security headers such as Content-Security-Policy and Strict-Transport-Security reduces protection against common web attacks. No exposed sensitive data or vulnerable libraries were detected. The absence of a security policy or incident response contact limits transparency and preparedness. GDPR compliance is incomplete due to missing privacy and cookie policies. Overall, the security posture is adequate for a personal portfolio site but should be enhanced to protect user privacy and improve trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add security headers like Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to enhance security.
  3. Publish a vulnerability disclosure or security.txt file to facilitate responsible reporting.
  4. Introduce an incident response policy and dedicated security contact channels.
  5. Consider adding accessibility improvements and analytics with privacy-respecting configurations.

Technical notes

Notes

The website uses a mature and well-supported technology stack centered on PHP and WordPress, supplemented by JavaScript and CSS for frontend functionality. Hosting via Websupport with DNSSEC and HTTPS indicates a secure and stable environment. The site is mobile-optimized and SEO-friendly, with clear navigation and rich content. No heavy analytics or advertising scripts reduce performance overhead and privacy risks. Technical debt appears low, but the absence of security headers and formal policies suggests areas for modernization. Overall, the infrastructure supports the business needs effectively with opportunities for security and compliance enhancements.
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.
