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

Builder.cz is a Czech online information portal focused on programming and development topics, operated by Web & Media a.s. The site offers articles, tutorials, and forums targeting programmers and developers interested in languages such as PHP, ASP, JavaScript, Delphi, and C++. It is part of a broader media group with several related projects in graphics, photography, printing, and Apple product communities. Technically, the website uses standard web technologies including HTML5, CSS, JavaScript, and jQuery, with Google Adsense for advertising and AddThis for social sharing. The site is served over HTTPS but lacks advanced security headers and cookie consent mechanisms, which impacts privacy compliance. No WHOIS data was available, which reduces domain trustworthiness, though the website content and related projects indicate a legitimate business. Contact is available via email and a contact form, but no phone numbers or physical addresses were found. Overall, the site is professionally maintained with good content quality and moderate technical implementation.

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

11 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

Builder.cz operates as a content publishing and community engagement platform within the Czech technology media sector. Its competitive advantage lies in its established network of related portals and a focused target audience of developers and programmers. The business model centers on advertising revenue and community-driven content. The presence of multiple sister sites under Web & Media a.s. suggests a stable ecosystem and diversified content offerings. Growth indicators include active content updates and social media integration. Strategic partnerships are evident with sister domains, enhancing cross-promotion and audience reach. The lack of detailed company registration data online suggests a need for improved transparency to bolster business credibility.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options exposes the site to potential risks like clickjacking and MIME sniffing. No explicit incident response or vulnerability disclosure policies are published, indicating limited preparedness for security incidents. The site collects user data via forms but lacks visible cookie consent mechanisms, which may lead to GDPR compliance issues. No vulnerable libraries or exposed sensitive data were detected in the provided content. Overall, the security maturity is moderate but could be significantly improved with standard best practices and compliance measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Add a cookie consent banner and update privacy policies to explicitly address GDPR compliance and user data handling.
  3. Publish an incident response plan and vulnerability disclosure policy to enhance transparency and readiness.
  4. Improve accessibility features to meet modern standards and enhance user experience for all visitors.
  5. Verify and update WHOIS domain registration information to improve domain trust and legitimacy.

Technical notes

Notes

The website uses a traditional web stack with HTML5, CSS, and JavaScript libraries such as jQuery. It employs Google Adsense for monetization and AddThis for social sharing, indicating integration with common third-party services. The CMS identified is WMpublic, a multi-editor system, which supports content management needs. Performance is moderate with no explicit optimization indicators; mobile optimization is basic but present. SEO is supported by meta tags and structured navigation. The site lacks modern frontend frameworks or advanced backend technologies visible from the HTML content. Technical debt appears low but modernization opportunities exist, especially in security and privacy compliance. Hosting provider details are not disclosed, limiting infrastructure assessment.
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.
