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

The website supkadavid.cz represents ADD ADVERTISING DESIGN, a small Czech graphic design agency founded in 2007. The company offers a range of services including graphic design, web design, corporate identity, printing materials, and advertising graphics. The website content is primarily in Czech and targets local clients seeking professional design services. The business appears to be a small, service-oriented agency with a focus on personalized client solutions and portfolio presentation. Technically, the website relies on outdated Flash technology, which significantly impacts usability, accessibility, and security. The site lacks modern web standards such as responsive design and accessibility features. There is no evidence of HTTPS enforcement or security headers, which weakens the security posture. Google Analytics is used for tracking, but no cookie consent or privacy policies are present, indicating poor privacy compliance. From a security perspective, the absence of HTTPS, security headers, and privacy policies are notable weaknesses. The use of Flash technology introduces potential vulnerabilities and compatibility issues. The WHOIS data shows a consistent and long-standing domain registration, supporting the legitimacy of the business. However, the website would benefit from modernization and improved security and privacy practices. Overall, the website scores moderately due to its business credibility and content relevance but is held back by technical and security shortcomings. Strategic improvements in technology stack, security implementation, and privacy compliance are recommended to enhance trust and user experience.

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

12 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. 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 CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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"

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.

Business context

Business profile

ADD ADVERTISING DESIGN operates as a small local graphic design agency in the Czech Republic, focusing on comprehensive design services including web design, corporate identity, and advertising materials. The business model is service-based, targeting clients needing professional graphic and web design solutions. The company has maintained a stable domain since 2007, indicating operational continuity. The website serves as a portfolio and contact point rather than an e-commerce or interactive platform. The lack of advanced digital marketing or privacy compliance features suggests a traditional business approach with limited digital maturity. Partnerships appear limited to the design agency's own domain and related portfolio sites. Growth indicators or revenue streams are not evident from the website content.

Security posture

The website exhibits a low security maturity level. Key vulnerabilities include the use of deprecated Flash technology, absence of HTTPS enforcement, and lack of security headers such as Content-Security-Policy or X-Frame-Options. No privacy or cookie policies are present, indicating non-compliance with GDPR requirements. The site does not provide incident response contacts or security policies. Google Analytics is implemented without visible consent mechanisms, raising privacy concerns. The overall security posture is weak, exposing the site and its users to potential risks. Immediate remediation should focus on migrating away from Flash, implementing HTTPS, adding security headers, and establishing privacy compliance measures.

Recommendations

  1. Migrate website content from Flash to modern HTML5/CSS3/JavaScript technologies to improve security, accessibility, and compatibility.
  2. Implement HTTPS with a valid SSL/TLS certificate to secure data transmission and improve user trust.
  3. Add comprehensive privacy and cookie policies with clear GDPR compliance and user consent mechanisms.
  4. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  5. Improve website accessibility and mobile responsiveness to enhance user experience and SEO performance.

Technical notes

Notes

The website is built using basic HTML, CSS, and JavaScript, with a significant reliance on Flash (SWF) for main content delivery, which is deprecated and unsupported by most modern browsers. The meta tags are present but limited to basic SEO and language settings. No modern frameworks or CMS platforms are detected. Hosting is provided by Tele3 as indicated by the registrar and name servers. Performance is likely slow due to Flash content and lack of optimization. The site lacks mobile optimization and accessibility features, limiting usability on modern devices. Google Analytics is used for tracking but without privacy controls. Overall, the technical infrastructure is outdated and requires modernization to meet current web standards and security best practices.
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.
