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

The website www.domena-webhosting.cz is an informational portal focused on webhosting and domain registration advice primarily for the Czech Republic market. Operated by THINline interactive s.r.o., it provides guidance on selecting webhosting services, domain names, free hosting options, and catalogs of providers. The site leverages affiliate partnerships with Czech hosting companies such as Český hosting and promotes related services like virtual and dedicated servers. The content is well-structured, relevant, and targeted at individuals and small businesses seeking hosting knowledge. Technically, the site uses standard HTML, CSS, and JavaScript with Google Analytics and Tag Manager for visitor tracking. However, it lacks modern security headers and privacy/cookie policies, which impacts compliance and trust. The absence of WHOIS data for the domain raises concerns about domain registration legitimacy, although the website content and footer information suggest a legitimate small business presence. Overall, the site is functional and informative but would benefit from enhanced security and privacy measures.

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 business operates in the technology sector, specifically providing webhosting and domain-related information and affiliate referrals. Its market position is niche and localized to the Czech Republic, targeting individuals and small businesses. The business model relies on content marketing and affiliate commissions from recommended hosting providers. The company THINline interactive s.r.o. appears to be the owner and operator, with no subsidiaries or parent companies indicated. The website's partnership ecosystem includes reputable Czech hosting providers and related service sites. Growth potential depends on expanding content, improving compliance, and enhancing trust signals. The lack of WHOIS transparency is a notable risk factor that could affect credibility with partners and users.

Security posture

The website demonstrates a basic security posture with no forms or user input fields that could introduce vulnerabilities. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security, which are best practices to mitigate common web attacks. The site uses HTTPS (assumed from modern standards, though not explicitly confirmed), but no explicit SSL configuration details are available. There is no evidence of privacy or cookie policies, incident response contacts, or vulnerability disclosure mechanisms, indicating gaps in compliance with GDPR and security transparency. The absence of WHOIS data for the domain is a significant concern, potentially indicating domain registration issues or privacy protection that is not justified for this business type. Overall, the security posture is moderate but requires improvements to meet modern standards and build user trust.

Recommendations

  1. Implement and enforce HTTPS site-wide with a valid SSL certificate and ensure strong SSL/TLS configuration.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and inform users about data collection.
  3. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  4. Publish contact phone numbers and physical address to improve business credibility and user trust.
  5. Create a security.txt file and establish an incident response contact channel to facilitate vulnerability reporting and improve security transparency.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS, and JavaScript. It integrates Google Analytics and Google Tag Manager for visitor tracking and marketing analytics. The site does not appear to use a CMS or modern JavaScript frameworks. Performance is moderate with basic mobile optimization and accessibility features. SEO is supported by proper meta tags and structured navigation. There is no evidence of technical debt or legacy code, but the site could benefit from modernization including responsive design improvements and enhanced accessibility compliance. Hosting provider details are not disclosed. Overall, the technical infrastructure is sufficient for a small informational site but could be improved for scalability and security.
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.
