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

Delex spol. s r.o. is a Czech advertising and communication agency established in 1992, offering a wide range of marketing, advertising, graphic design, printing, event production, and publishing services primarily targeting businesses in the Plzeň region. The company positions itself as a full-service agency with experience and resources to meet diverse client needs. The website is built on WordPress with common plugins and technologies, providing a professional and user-friendly experience with clear contact information. Security posture is moderate with HTTPS enabled and anti-spam measures in place, but lacks advanced security headers and visible privacy or cookie policies, indicating compliance gaps. The absence of WHOIS data limits domain legitimacy verification, which slightly reduces trustworthiness. Overall, the website is functional, professional, and safe for general audiences but would benefit from enhanced privacy compliance and security practices.

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

8 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

Delex operates in the media and advertising sector as a small-sized, established local agency with a broad service portfolio including marketing analyses, multi-channel advertising campaigns, graphic and web design, printing, event management, and publishing. Their business model focuses on service provision to local and regional clients, leveraging long-term experience since 1992. The company maintains a professional web presence with clear contact details and branding consistency. However, the lack of WHOIS transparency and privacy policies suggests areas for improvement in trust and compliance. No evident partnerships or subsidiaries were identified from the website content or linked domains.

Security posture

The website demonstrates a basic to moderate security maturity level with HTTPS enabled and use of CleanTalk anti-spam protection. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. There is no visible incident response or vulnerability disclosure information, and privacy compliance is weak due to missing privacy and cookie policies. These gaps could expose the business to compliance risks under GDPR and other regulations. Enhancing security headers, publishing privacy documentation, and establishing incident response contacts would improve security maturity and trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies with visible user consent mechanisms to ensure GDPR compliance.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options to strengthen website security.
  3. Publish a security.txt file and provide clear incident response contact information to improve transparency and readiness.
  4. Regularly update WordPress core and plugins to mitigate vulnerabilities and maintain security hygiene.
  5. Consider verifying and publishing WHOIS domain registration details to enhance domain legitimacy and trust.

Technical notes

Notes

The website is built on WordPress 6.8.1 with common plugins such as Photo Gallery and CleanTalk anti-spam. It uses jQuery 3.7.1 and Google Fonts for styling. The site loads moderately fast and is mobile optimized with responsive design elements. SEO optimization is basic with standard meta tags and canonical links. Accessibility features are minimal but present. There is no evidence of advanced frameworks or custom backend technologies. Hosting provider details are not disclosed. The technical stack is standard for small business websites but could benefit from performance and security 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.
