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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 · found on this site
  • 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 platform operates as a content aggregator and community hub for book reviews, leveraging user-generated content from over 100 blogs and nearly 10,000 books reviewed. Its business model likely revolves around content engagement and possibly advertising or donations, as indicated by a 'Buy me a coffee' link. The site’s market position is niche but stable, serving Slovak and Czech literary communities. Partnerships include social media channels and a web developer's site. Growth indicators include active blog additions and a sizable review database. The platform’s competitive advantage lies in its localized focus and aggregation of diverse literary opinions.

Security posture

Knihomola.sk demonstrates a moderate security posture with mandatory HTTPS and cookie consent compliance. However, it lacks explicit security policies, incident response contacts, and security.txt files. The absence of security headers like Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No exposed sensitive data or vulnerable libraries were found. The site uses third-party analytics and social SDKs, which may increase tracking risks but are industry standard. Overall, the security maturity is adequate for a content platform but could be improved with formal policies and enhanced headers.

Recommendations

  1. Implement and publish a comprehensive privacy policy detailing data handling and GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to meet recognized standards and improve user inclusivity.
  5. Establish an incident response contact channel to improve transparency and readiness.

Technical notes

Notes

The website uses a combination of well-known JavaScript libraries and frameworks including jQuery, Bootstrap, Owl Carousel, and Modernizr, ensuring compatibility and responsiveness. Google Analytics and Tag Manager are used for tracking and marketing purposes, integrated asynchronously to optimize load times. Hosting is provided by Webglobe, a known provider, with domain DNS configured accordingly. The site loads moderately fast with good SEO metadata and Open Graph tags for social sharing. Some technical debt is noted in the lack of security headers and absence of structured data like JSON-LD. The site is mobile-optimized and accessible but could benefit from enhanced accessibility and performance tuning.
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.
