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

The website www.blabolnik.cz is a personal blog and archive maintained by an individual known as Plaváček, focusing on web design, SEO, and internet culture topics primarily in the Czech language. It serves as a repository of articles and commentary with a nostalgic and historical perspective on the evolution of the internet and web technologies in the Czech Republic. The business model is minimal, relying on content publishing, occasional book sales via external links, and voluntary donations through PayPal. The site targets general internet users interested in these niche topics. Technically, the site uses an older technology stack including jQuery, jQuery UI, and Lightbox, with a CMS identified as Pub-Me CMS. Hosting is provided by a Czech hosting provider named Levný webhosting. The site shows moderate performance and basic mobile optimization but suffers from mixed content issues due to loading many scripts and stylesheets over HTTP instead of HTTPS. The use of deprecated Google Analytics urchin.js indicates outdated analytics implementation. From a security perspective, the site lacks modern security headers and has mixed content vulnerabilities, which could expose users to risks. No privacy or cookie policies are present, and no contact information is provided, limiting compliance with GDPR and other privacy regulations. The WHOIS data is unavailable, which raises concerns about domain legitimacy verification, although the site content and branding appear consistent with a personal blog. Overall, the site is functional and provides valuable content to its niche audience but requires technical and security improvements to enhance user safety, privacy compliance, and trustworthiness.

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. 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

  2. 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

  3. 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

The website operates as a small-scale personal blog with a niche focus on web design and SEO topics in the Czech Republic. It leverages content publishing as its primary service, supplemented by book sales and donations. The market position is that of a legacy or pioneer blog with historical significance rather than a commercial enterprise. The business model is low complexity, with no evident revenue streams beyond donations and book sales. The partnership ecosystem includes links to related Czech websites and hosting providers but no formal partnerships or subsidiaries. Growth indicators are limited, reflecting the archival nature of the content. The site’s operations are straightforward, with minimal technical complexity and limited digital marketing or monetization strategies.

Security posture

The security posture of the website is basic and shows several areas for improvement. The presence of mixed content due to HTTP resources on an HTTPS site is a significant vulnerability that can expose users to man-in-the-middle attacks. The absence of modern security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. The use of outdated analytics scripts and JavaScript libraries may introduce vulnerabilities. No privacy or cookie policies are present, indicating non-compliance with GDPR and related regulations. The lack of WHOIS data further complicates trust verification. Incident response and security policy information are not provided, suggesting limited security governance. Overall, the site’s security maturity is low, and it is recommended to address these gaps promptly.

Recommendations

  1. Migrate all website resources to HTTPS to eliminate mixed content vulnerabilities and improve user security.
  2. Implement modern security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against web attacks.
  3. Update analytics implementation to use the latest Google Analytics version and remove deprecated scripts.
  4. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  5. Obtain and maintain accurate WHOIS domain registration data to enhance domain legitimacy and trustworthiness.

Technical notes

Notes

The website uses a legacy technology stack centered around jQuery and Lightbox, managed via the Pub-Me CMS platform. Hosting is provided by a Czech hosting company. The site’s performance is moderate but hampered by mixed content issues due to HTTP resource loading. Mobile optimization and accessibility are basic, with no advanced features detected. SEO optimization is minimal, with basic meta tags but no structured data or Open Graph tags. The site’s design is functional but dated, reflecting its archival nature. Technical debt is evident in the use of outdated analytics and JavaScript libraries. Modernization opportunities include updating the tech stack, improving HTTPS adoption, and enhancing SEO and accessibility features. Technical risks include potential vulnerabilities from outdated libraries and mixed content exposure.
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.
